Research fellow opportunity at the University of Toronto-Scarborough
The Cadotte lab at the University of Toronto-Scarborough is looking for a
Postdoctoral researcher in ‘ecological dynamics in urban ecosystems’.
Urban green areas provide important ecosystem function and services to large
human populations. While there have been numerous experiments assessing the
effect of diversity on ecosystem function, there has not been a comprehensive
attempt to apply these principles to existing ecosystems. Urban green areas
represent a number of different ecosystem types and different management
policies that directly or indirectly affect species diversity, thus affecting
functioning within green areas. At a larger scale, a diversity of types of green
areas may provide greater service than repeated, singular types of green areas.
Given this diversity and the fact that municipalities depend on the ecosystem
functions and services provided by urban green areas, it is important to
understand the biological components of ecosystem function.
I am looking for a postdoctoral research fellow to join our team to address
questions broadly related to terrestrial diversity and ecosystem function in urban
areas. Examples of the types of research questions of interest include: 1) how do
plant invasions influence (disrupt or enhance) the ecosystem functions provided
by urban green areas? 2) How are plant-soil feedbacks affected by urban
environments? 3) How does plant diversity (taxonomic, functional, or
phylogenetic) influence pollinators (diversity or service provisioning) in urban
green areas. Or any other related question.
Toronto is uniquely situated to be the focus of urban ecology research as it has a
number of large green areas, with the flagship being the new Rouge Urban
National Park, situated on the University of Toronto-Scarborough’s doorstep.
Further, Toronto contains several replicate watersheds, each with large ravine
forests, semi-wild parks, maintained parks, and small green areas. Projects will
necessarily involve developing partnerships with local governmental and non-
governmental organizations, and the work will be put into a broader context that
should benefit outside groups.
I am looking for a terrestrial community or ecosystem ecologist with broad
ecological interests. Desirable skills/interests include spatial analyses,
quantitative modelling, plant-insect interactions, soil biodiversity, functional or
phylogenetic diversity, and R programming. Candidates should have strong:
conceptual/theoretical understanding of ecological processes; oral and written
communication skills; publication record; and an interest in outreach. The
candidate should have completed, or nearly completed, a PhD in ecology or
related disciplines. The successful candidate will be expected to provide
leadership in the lab, and interact with graduate and undergraduate students.
The Cadotte lab also has a strong commitment to outreach, running programs
with local elementary schools, and the candidate is expected to participate.
The University of Toronto-Scarborough (UTSC) is located on the eastern edge of
Toronto, and makes up one of the three campuses of the University of Toronto.
The tri-campus Ecology and Evolutionary Biology program, which also includes
the Royal Ontario Museum (http://www.eeb.utoronto.ca/), is an excellent
department with more than 50 faculty members
(http://www.eeb.utoronto.ca/people/G-faculty.htm). The candidate will be housed
at UTSC, in the Biological Sciences department
(http://www.utsc.utoronto.ca/biosci/), which sits on a forested ravine, and is a
relatively short commute to the Toronto city centre. UTSC is an exciting place to
do research, with a relatively young and active research community, and
excellent students. Toronto is Canada’s largest city and is extremely culturally
diverse, full of parks and green areas, and hosts numerous cultural, culinary, and
The start date is flexible, but May 2015 is preferred, and the position is for two
years –second year contingent on first year performance. The salary is
$40,000/year, and comes with a benefits package. Postdocs are unionized at the
University of Toronto.
Applicants are required to send an updated CV, two representative reprints or
preprints, a cover letter and/or statement describing the candidate’s past
experience and accomplishments, interests (generally and with respect to the
specifics of this position), and the names and e-mails of at least two references.
These materials should be combined into a single pdf document and sent to
firstname.lastname@example.org. Applications will be accepted until September 19th,

Dr Keith Kirby Awarded Top Eco Medal
Renowned woodland expert awarded prestigious ecology medal in recognition of a lifetime’s work
This year the Chartered Institute of Ecology and Environmental Management (CIEEM) will present its most prestigious award, the Institute Medal to Dr Keith Kirby FCIEEM, a woodland ecologist at Oxford University, in recognition of his contribution to driving forward woodland conservation in the UK.
The Award will be presented by Andrew Sells, the newly appointed Chair of Natural England, on Thursday 26 June 2014 at Birmingham Botanical Gardens at the 2014 CIEEM Awards ceremony, which recognises outstanding achievements by organisations and individuals in the fields of ecology, environmental management and sustainability.
Regarded by his peers as the ‘oracle on woodlands’, Kirby’s career has spanned nearly forty years. He gained a first class honours degree in Agricultural and Forestry Sciences from Oxford University in 1973, and went on to complete a doctorate on multiple aspects of bramble ecology in 1976. Since retiring from Natural England in 2012, Kirby has returned to Oxford University in the Department of Plant Sciences where he continues to write about woodland conservation.
He co-edited Wytham Woods (OUP) based on Oxford’s ecological field laboratory which is home to some of the longest running field research in conservation management. Here, Kirby has commissioned and conducted research which has closely monitored the impact of rising deer numbers on woodland environments, and how tree canopies may slow the pace of climate change at ground level.
Following the announcement of his award Keith Kirby commented, “I am very pleased to be honoured in this way. I have worked in woodland ecology for nearly forty years, yet that is merely a tenth of the time it would take a single oak tree to reach biological maturity. Trees have been under threat from mankind since the invention of the first axe, and natural disasters such as the great storm of 1987 still leave an ecological legacy today, making long term monitoring an essential part of woodland conservation.”
Sally Hayns, Chief Executive of CIEEM says, “The Institute Medal is CIEEM’s highest accolade and we are delighted to be presenting it to Keith Kirby this year. He has dedicated his life and career to topical and applied research on issues such as climate change and tree disease, basing his theories on sound woodland ecology which has made him a highly reputable and sought after voice in the field. He leads by example, minimising his own personal footprint wherever possible, and providing guidance to young emerging ecologists.”
Kirby has worked as a woodland ecologist for the government’s statutory nature conservation agencies – in their various incarnations, firstly with the Nature Conservancy Council, then English Nature, and most recently Natural England – developing national policies in forestry and advising the UK government on forest sustainability and rewilding. He is also a Fellow of both CIEEM and the Institute of Chartered Foresters, while being a long-serving member of the British Ecological Society and the Royal Forestry Society.
In academic circles he has actively engaged with students providing guidance, teaching and mentoring on projects from a number of prestigious institutions, including University College London, Birkbeck University of London, Imperial College London and the University of Liverpool.
Emma Goldberg and Richard Jefferson, both from Natural England, jointly nominated Keith Kirby for the award, stating, “Keith is widely respected by his peers in the forestry industry as the oracle on woodlands. His guidance and teaching of individual students, courses, and talks to the general public, and his wisdom over policy-related matters, mean that he has driven woodland conservation forward hugely over the course of his career.”

Eutrophication weakens stabilizing effects of diversity in natural grasslands
Members of the department were united today in remembrance of Professor Lorna Casselton CBE FRS. Her funeral provided an occasion to mourn her passing and to celebrate her life.
Lorna was an outstanding scientist whose passion and enthusiasm inspired all around her; ten years after her retirement she frequently came into the Department to talk to postdocs and students about their research. She was always encouraging and could always offer practical suggestions to solve any problems presented.
Above all, Lorna was a highly respected colleague and friend to many of us. She had been a member of the Plant Sciences Department for over 20 years and was proud to call it her base when she was Vice President of The Royal Society after her retirement.
She will be greatly missed.
'Tree of life' distances are no shortcut to conservation
Attempts to preserve the most diverse range of biological features that target which organisms to save based on distances on a 'tree of life' may not succeed, Oxford University research suggests.
Some conservation strategies assume that the evolutionary distances between species on a phylogenetic 'tree of life' (a branching diagram of species popularised by Charles Darwin) can be used to predict how diverse their biological features will be. These distances are then used to select which species to conserve in order to maximise interesting biological features - such as potentially useful drug compounds and resilience to climate change.
But a new analysis of data from 223 studies of animals, plants, and fungi, shows that methods based on such distances are often no better at conserving interesting biological features than picking species at random. A report of the research is published this week in the journal Diversity and Distributions.
"Whilst 'close neighbours' on the branches of the tree of life are likely to share more biological features than distant ones, we found that you only have to move a short distance away before predictions about how much more diverse an organism's features should be are no better than a random choice," said Dr Robert Scotland of Oxford University's Department of Plant Sciences. "Much of this may be down to parallel or convergent evolution that sees similar biological features - such as eyes and wings - evolving independently again and again throughout the history of life."
The new analysis suggests that phylogenetic distance by itself is not an adequate way of prioritising which organisms are most dissimilar to target for conservation.
"Maximising biological feature diversity is clearly important to conservation but you won't achieve this if you don’t select the right range of species, and our study shows that you are unlikely to select the right range of species if you use phylogenetic distance," said Dr Scotland. "What our work suggests is that we need better, more nuanced, methods for identifying feature diverse species to underpin conservation strategies."

Land-use intensity and the effects of organic farming on biodiversity: a hierarchical meta-analysis
A paper entitled "Land-use intensity and the effects of organic farming on biodiversity: a hierarchical meta-analysis" is published today in the Journal of applied Ecology by Sean L. Tuck, Camilla Winqvist, Flávia Mota, Johan Ahnström, Lindsay A. Turnbull, Janne Bengtsson
We analysed 30 years of studies comparing the number of species on organic and conventional farms. We found that, on average, organic farming increases the number of species by a third. This shows that organic farming is a tried and tested method for increasing biodiversity on farmlands. Organic farming is therefore an important tool in reversing continued declines of formerly common species in developed nations.

To value our ancient woods we must estimate the cost of 'irreplaceable'
An article by Keith Kirby, University of Oxford published at The Conversation.
The threat to Britain’s ancient woodland has been much discussed recently, the suggestion being that where they are lost to housing development they might be replaced with new woods through biodiversity offsetting schemes.
This issue will need to be addressed, particularly in relation to HS2, the route of which is likely to cut through or close to about 60 ancient woods.
So what makes ancient woodland different? After all, 40 years ago the term was virtually unknown, even in conservation circles.

G E blackman lecture given by Scott Poethig from the University of Pennsylvania
Scott Poethig from the University of Pennsylvania gave the G E Blackman lecture this afternoon. As plants age they go through distinct phases that are defined by changes in their morphology and physiology. This is shown clearly in ivy, where the juvenile leaves are pointed and the adult leaves rounded. Using painstaking genetics, Scott’s lab discovered that two highly conserved micro RNAs regulate these phase changes. More recently he showed that the same microRNAs control phase change in woody plants like Acacia. This indicates that an ancient microRNA network controls phase change in flowering plants and the same mechanism operates in short lived plants like Arabidopsis and long lived woody trees like acacia.

(This session formed part of their assessment module entitled "Getting the public excited about your science".)
The afternoon was a great success and was rounded off with tea and cake in the Conservatory at the Oxford Botanic Garden.
How the daffodil got its 'trumpet'
The daffodil is one of the few plants with a 'corona', a crown-like structure also referred to as the 'trumpet'. New research suggests that the corona is not an extension of the petals as previously thought, but is a distinct organ sharing more genetic identity with stamens, the pollen-producing reproductive organs.
The origin of the corona has long been a subject of debate in botany, and in the 1930s botanist Agnes Arber claimed that it was an extension from the petals. With its colourful petal-like appearance, it's easy to see why this was believed for so long. Yet by studying the corona's development and genetic information, this new study has shown that it is in fact related to stamens.
Dr Robert Scotland of the University of Oxford led the research, and was supported by colleagues at Harvard University, the United States Department of Agriculture and the University of Western Australia. The researchers were funded by the Gatsby Charitable Foundation and the United States National Science Foundation. The study is published online in The Plant Journal.
By studying the development of daffodil flowers, the researchers found that the corona only begins to form after the other parts of the flower are fully established. 'This shows that the corona could not be a straightforward modification of either petals or stamens,' explains Dr Scotland, 'Since it develops independently of both, it is more accurately described as a separate organ.'
The different parts of daffodil flowers are located on a small cup-like platform termed the 'hypanthium'.
The researchers analysed genetic activity in all parts of the daffodil flower, and found that daffodil coronas were genetically similar to the stamens and hypanthium, but not the petals.
'We found that the corona develops from the hypanthium, and is not simply an extension of the petals or stamens,' says Dr Scotland, 'The corona is an independent organ, sharing more genetic identity with stamens, and which develops after the other organs are fully established.'

Kirsty Monk joins forces with local school to bring science to life for children
Kirsty Monk, in collaboration with Mrs Geerthi Ahilan, Science co-ordinator at St Ebbe’s C.E. (Aided) Primary School have won a Royal Society Partnership Grant, worth £2896 for their study, "War and Peace: Species interactions on Hogacre Common".
Children from all years from foundation stage to year 6 will be involved in this exciting project to assess and interrogate the biodiversity on and ecosystem services provided by hogacre common. This 11 acre plot of old private sports field has been leased to the community by Corpus Christi College and contains areas of grassland (managed and unmanaged), scrubland, woodland and waterways. In collaboration with Low Carbon Oxford, St Ebbe's Primary School aims to convert this diverse area into a rich community resource. By partnering with Kirsty Monk, the children will experience all aspects of an ecological investigation, from planning, sampling and data collection to data manipulation, analysis and conclusion drawing. This project will meet the learning requirements of all ages through stratified tasks, incorporating art, mathematics and literacy as well as science, and involving partnership with New Hinksey Primary school and Grandpont Childrens Centre, both of which are part of the same community. This will be an invaluable project to both the schools and the local community who will benefit from a greater understanding of the biodiversity of the common and the enhancement resulting from the restoration and conservation aspects of the project.

Prestigious award from the Royal Geographical Society Slawson Grant
Congratulations go to Fran Lambrick, who has been awarded a prestigious award from the Royal Geographical Society Slawson Grant for her project 'Community Forestry in Cambodia: Ecological effects and Potential for Climate Mitigation Funding'. The awards are to "support geographical fieldwork involving development issues with a high social and economic value" and will contribute towards Fran's DPhil project on the effect of community forestry in Cambodia. There has been rapid global increase in the area of community forestry (CF), which aims to support livelihoods and conserve forests. Cambodia has recently expanded CF, but no independent studies have evaluated the results. Fran's research investigates the effect of CF on biodiversity, regeneration and biomass at 20 forest sites in central Cambodia, comparing CF sites with paired controls. Fran addresses the feasibility of using CF to deliver deforestation reductions, which could bring economic and social benefits to isolated communities. She also considers the ecological and social risks of creating a new carbon commodity market in the area. Well done Fran!

Harriet McWatters co-authors important study of Malaria Parasites
Anyone who has ever taken a trans-Atlantic flight is aware of jetlag. Most people dismiss it as no more than a temporary inconvenience, but for malaria
parasites infecting the red blood cells of their host, getting the timing right is, literally, a matter of life and death. Harriet McWatters, a chronobiologist from Oxford University, working with malaria researchers at the University of Edinburgh, has shown that if parasites do not align their lifecycle with the bodyclock of their host they suffer a 50% reduction in their ability to cause infection and spread disease.
The findings of this research may be found online in: A.J. O'Donnell, et al., "Fitness costs of disrupting circadian rhythms in malaria parasites," Proceedings of the Royal Society B, doi:10.1098/rspb.2010.2457.

Lorna received back a piece of wood from Isaac Newton's apple tree that had been taken to the International Space Station in May. One of the 6 astronauts was British-born Piers Sellers, who took both the wood and a picture of Isaac Newton to the Space Station on behalf of the Royal Society. This photograph was taken in the atrium of the Royal Society, where the the world's first international satellite hangs.
Congratulations to Dr Lee Sweetlove
Lee Sweetlove is part of an international consortium that has been awarded 1.1 million Euros through the ERASYSBio Plus scheme to work on a multi-scale model of tomato fruit growth and metabolism. The consortium consists of 6 partner laboratories from the University of Oxford (Sweetlove), Oxford Brookes University, The University of Bordeaux, INRA Avignon, Max-Planck Institute for Molecular Plant Physiology and The University of Stellenbosch.
Commercial fruit production is under significant pressure from environmental stresses, but also by changes in the consumer's demand for taste and nutritional value. One of the key goals of fruit biology is therefore to understand the factors that influence the levels of metabolites in cells and tissues, ultimately with a view to manipulating these levels for improvement of fruit traits. Both genetic and environmental factors have a strong and multifaceted influence on fruit quality. They usually act and interact in such a complex way that it is extremely difficult to study their effects experimentally. To circumvent such difficulty, an integrative model of fruit metabolism in the tomato will be built.

The Future of Plants
The Department's vision of Plants for the 21st Century is highlighted in the latest 'Blueprint' magazine. In an article in the May edition of the magazine, Jane Langdale describes how a 21st century herbarium should be a comprehensive electronic resource combining modern mapping technology with high-quality images and data. The knowledge held by traditional herbaria would be enhanced with the enormous quantities of digital information about plants and ecosystems that is being collected every day by researchers in the field. The data held in the ‘e-herbarium’ would be easily available to anyone, from Government policy makers to rare plant enthusiasts. Funding from the InterContinental Hotels Group, the Bill and Melinda Gates foundation and the James Martin foundation are helping to make this vision a reality.

Insect Pollination POST Briefing Note by Rebecca Ross
Rebecca Ross, a DPhil student in Plant Sciences, has recently published a science policy briefing note on Insect Pollination. This was written during her three-month Fellowship at the Parliamentary Office of Science and Technology, sponsored by the British Ecological Society. The Parliamentary Office of Science and Technology (POST) provides independent, balanced and topical analysis of public policy issues related to science and technology to inform MPs and Lords. Recent briefing notes have covered topics as broad as: Diagnosing Dementia, Climate Change Engagement and Behaviour, and Technology for the Olympics.
Insect pollination is a highly topical and relevant issue as many plants, including crops, depend on insects to transfer pollen between flowers. Maintaining enough insect pollinators is therefore vital for biodiversity and a diverse food supply. Declines in pollinators, particularly in Europe and the USA, have provoked claims of a global pollination crisis. The POSTnote examines the risks of pollinator decline for the UK and explores strategies to provide stable pollination services into the future.
A seminar was held to launch the Insect Pollination note in Parliament on January 20th 2010.
The POSTnote can be downloaded from the POST website here:

Department's research highlighted in the Oxford Science Blog
Feeding the future Guest: Penny Sarchet | 06 Jan 10
At the current growth rate the global population is predicted to reach 10 billion by 2050. To feed this many people, food production worldwide will need to double during a period when climate change will worsen, fossil fuels will dwindle, and water availability will become unpredictable.
In addition, if we are to protect what biodiversity we can, this doubling of agricultural output must take place using the same amount of farmland, without impacting upon remaining natural habitats.
To tackle this problem, scientists in Oxford University’s Department of Plant Sciences are aiming to develop high-yield crop strains which will be better adapted to this climate-altered, resource-poor agricultural landscape of the near future.
Boosting rice crops
Professor Jane Langdale, Head of the Department of Plant Sciences, is engaged in the ‘C4 Rice’ project, an international effort funded by the Bill & Melinda Gates Foundation [more here]. 700 million people in Asia currently depend on rice for the bulk of their calorific intake and it is predicted that during the next 40 years, rice production needs to increase by 50 per cent in order to feed the growing Asian population, whilst adapting to adverse changes in climate and water availability.
Photosynthesis converts carbon dioxide and the energy from sunlight into chemical energy and takes place in cell organelles called chloroplasts. The chemical energy produced in these chloroplasts is then used by plants to live, grow, and in the case of crops, produce grain.
Conventional rice varieties use a standard photosynthesis pathway known as ‘C3’, but under certain conditions, such as warmer temperatures, this pathway is inefficient. A number of plants, including maize, have evolved an extra photosynthesis pathway, called ‘C4’, to solve this problem. The C4 photosynthesis pathway can increase efficiency by 50 per cent and iintroducing it into rice could provide the answer to Asia’s impending food problem.
The C4 Rice project is often quoted as being ‘highly ambitious’. In order to work, large changes need to be made to both the anatomy of rice leaves and the chemical reactions that take place inside them. However, there is encouraging evidence that it could be done.
Jane’s work on the GLK genes suggests that they may play a role in regulating whether a plant’s chloroplasts use C3 or C4 photosynthesis. Ongoing work in her laboratory seeks to put GLK genes from maize, a naturally C4 crop, into rice plants. Her work on chloroplasts began due to an interest in the genetic control of development in plants, rather than a specific aim to put C4 photosynthesis into other plant species. Whilst developing new C4 crops had always seemed like an interesting idea, she never thought it would be realistic.
20 years of chloroplast research later, Jane was ready to move into new research areas. It was at this point, in 2006, that the International Rice Research Institute (IRRI) invited Jane to a C4 Rice Consortium workshop. Originally reluctant to go, she was persuaded to attend by Julian Hibberd from the University of Cambridge, and found herself getting excited by the proposed project. She is now 5 months into a 3 year “proof of concept” project involved in testing the feasibility of C4 Rice, a necessary step called for by a paper inCurrent Opinions in Plant Biology written with Julian and John Sheehy from IRRI last year.
Using less fertiliser
As well as facing climate change, 21st century agriculture will also have to cope with the decline in fossil fuels. The work of Oxford’s new Sherardian Professor of Botany, Liam Dolan, aims to produce crops which grow healthily without excessive phosphate-rich fertiliser application.
Phosphate is required by all living organisms to build cellular components and the low availability of phosphate in natural environments can severely limit plant growth. The soil of all of sub-Saharan Africa and one third of China is deficient in this crucial nutrient. The application of artificial fertilisers all over the world has so far dealt with this problem and contributed to the increase in productivity seen in the Green Revolution of the 20th Century.
Phosphate is extracted from mines, mainly in Morocco, the USA, China, the Former Soviet Union and South Africa, with 80 per cent of the phosphate produced being put into fertilisers. The extraction and transport of phosphate for agricultural use constitutes a considerable annual cost and carries a large carbon footprint. Furthermore, like oil, phosphate reserves are finite, and some predictions claim that phosphate mines could be exhausted within the next 30 years.
Liam’s work aims to develop crops which are better adapted to scavenge their own phosphate from the soil, making them less dependent on artificial fertilisers.
Plants can naturally extract their own phosphate from the soil using root hairs, single-cell structures which grow along roots. Liam’s research group have discovered a family of genes which control root hair growth and they are working to modulate the expression of these genes in crop plants. Their aim is to increase the number of root hairs a plant produces in response to naturally occurring phosphate in the soil. They have developed transgenic wheat and rice varieties capable of producing longer root hairs and are now moving on to field experiments to test the yield of these plants in the absence of commercial fertiliser.
Unlike Jane Langdale’s chloroplast work, this has always been the aim for Liam. He jokes that his team are now finally at the stage he had hoped to be at by the end of his PhD, explaining that this has been a very large project, starting from scratch and requiring the discovery of all the necessary genes involved.
Planning for 21st Century
In light of the global food security crisis we will soon be facing, the University’s Department of Plant Sciences will next year be launching a 21st Century Cropsresearch initiative. This initiative seeks to found an Oxford Professorship in Crop Science and to encourage translational research, so that discoveries made about plant metabolism, growth and development can be transferred to agriculturally valuable crop plants.
However, both Jane and Liam believe that whilst plant science has a lot to offer in solving the food security challenge, the role of governments and funding bodies is crucial, a point that was emphasised at the 'Food Security in the 21st Century' Symposium hosted by the Department’s graduate students last October.
Due to the unequal distribution of global wealth, the countries facing the most immediate problems do not have the funds to overcome them. Jane argues that to tackle food security there must be sustained funding and input from wealthy countries in order to bring about developing nation benefits. Liam points out that every day the same number of people die from malnutrition as from cancer, reflecting the bias of interest in developed countries. However, whilst scientific research alone cannot solve the issue of food security in the face of global politics, it is, says Jane, a very exciting time to be a plant scientist.

Congratulations to Xiaoqi Feng!!
Congratulations to Xiaoqi Feng, who was presented with the Young Scientist of the Year award at the recent Society for Experimental Biology meeting in Glasgow.
Xiao was awarded the first prize of £600 for her talk in a competition designed to recognise the best young researchers. This award is open to PhD students and those in the first three years of their first postdoctoral position.
Xiao’s talk which won the award was under the title of "Cell lineages determine the fates of germ cells and their tapetal feeder cells in the Arabidopsis anther". In her work with Professor Hugh Dickinson, she discovered that the male reproductive cells and their feeder cells in the plant Arabidopsis each develop from a distinct lineage – just as in animals. This discovery changes our current ideas about plant development, as well as opening up potential new strategies for improving seed production.

Departmental contribution to new exciting study on evolution of leaf shape
Work from our Department features in a recent “Science” paper demonstrating that CUP SHAPED COTYLEDON transcriptional regulators are necessary to direct compound leaf formation in diverse plant species ranging from the basal eudicot Columbine to pea, tomato and mustards (http://www.sciencemag.org/cgi/content/abstract/322/5909/1835). Compound leaf morphology was independently derived in these lineages, therefore this comparative investigation is a striking example of the repeated evolutionary deployment of a key developmental regulator in sculpting diverse organ shapes. The study makes heavy use of the Arabidopsis thaliana relative, Cardamine hirsuta, which is a novel model system developed by Miltos Tsiantis and Angela Hay who collaborated on this study with P.Laufs in Versaille who lead the study.
The story is also featured in a news article in “Nature”
The Department is pleased to announce the results of the 2008 Research Assessment Exercise. Based on three criteria (percentage 4*, GPA and 'rank of ranks') we have been ranked 4th out of 52 Biological Sciences Research Institutions in the UK.
Graduate students win the Environment YES competition
A team of graduate students, four from Plant Sciences Department, have been rewarded for their exceptional entrepreneurial skills by scooping first prize of £1000 in the Environment Young Entrepreneurs Scheme (YES) competition. The Oxford team are Rebecca Ross, Xiaoqi Feng, Christina Vinson, Gillian Petrokofsky and Bartu Ahiska. They beat teams from universities across the UK to the final prize and impressed the judges with their virtual business ‘ProBee’, which they say would offer a solution to the serious problem of colony collapse disorder. The national competition, run by NERC and BBSRC encourages young scientists to develop skills and contacts needed to turn research into commercially viable products and to pitch their ideas to a panel of potential investors.
Liam Dolan has accepted appointment to the Sherardian Professorship of Botany and will join the Department in September 2009.
Liam Dolan is undoubtedly one of the major contributors to our understanding of how developmental mechanisms operate in plants. His research will complement and enhance current activities in the Department.

Project Title - Evolution of Development In Plants
Abstract - Different morphologies evolve in different organisms in response to changing environments. As land plants evolved, developmental mechanisms were either generated de novo, or were recruited from existing toolkits and adapted to facilitate changes in form. Some of these changes occurred once, others on multiple occasions, and others were gained and then subsequently lost in a subset of lineages. Why have certain forms survived and others not? Why does a fern look different from a flowering plant, and why should developmental biologists care? By determining how many different ways there are to generate a particular morphology, we gain an understanding of whether a particular transition is constrained. This basic information allows an assessment of the extent to which genetic variation can modify developmental mechanisms and an indication of the degree of developmental plasticity that is possible and/or tolerated both within and between species. This proposal aims to characterize the developmental mechanisms that underpin the diverse shoot forms seen in extant plant species. The main goal is to compare developmental mechanisms that operate in vegetative shoots of bryophytes, lycophytes, ferns and angiosperms, with a view to understanding the constraints that limit morphological variation. Specifically, we will investigate the developmental basis of three major innovations that altered the morphology of vegetative shoots during land plant evolution: 1) formation of a multi-cellular embryo; 2) organization of apical growth centres and 3) patterning of leaves in distinct spatial arrangements along the shoot. To facilitate progress we also aim to develop transgenic methods, create mutant populations and generate digital transcriptomes for ‘model’ species at key phylogenetic nodes. The proposed work will generate scenarios to explain how land plant form evolved and perhaps more importantly, how it could change in the future.

The species is derived from hybrids of two closely related Senecio species growing on Mount Etna in Sicily1,2. Unlike the British endemic, which is now geographically isolated from these taxa, the mechanisms maintaining species differences in the hybrid zone on Mt. Etna are unclear. A cline in gene frequencies is observed between the two species on Mt. Etna which may be caused by diversifying selection (heterozygote disadvantage) or simply recent hybridization. To interpret the cline, we will conduct a multigenic DNA diversity and divergence study of high and low altitude Senecio species from Mt. Etna to estimate the length of time the two species have been hybridizing and when the two species diverged. In addition, the role of gene flow and natural selection in the maintenance of key reproductive traits will be studied by sequencing genes differentially expressed in capitulum (inflorescence) buds and flower buds. Flowering physiology differs between the two Senecio species growing at high and low altitude, and aspects of key reproductive traits are likely to be adaptive responses maintaining these different evolutionary units.

The paper reports the putative spread of an advantageous allele across the range of two hybridizing plant species. Such sharing of adaptive mutations by several species may be an important mechanism of adaptation in plants.
The results also illustrate that recovery of population structure after the sweep occurs quickly at the local scale, but much more slowly at the continental scale, resulting in a counter-intuitive pattern of high population structuring at the level of demes and very little structure at higher population/species levels.

Research from the Gurr lab featured on the front cover of Plant Cell
The paper by Pari Skamnioti and Sarah Gurr demonstrates that cutinase is involved during penetration of host plant cells by the rice blast fungus, Magnaporthe grisea. Using a cutinase mutant they are able to show that cutinase is required for surface sensing leading to correct germling differentiation, penetration, and full virulence in this model fungus.

New book on the Flora Graeca by Stephen Harris
The Book is called The Magnificent Flora Graeca.
Publisher: Bodleian Library.
ISBN: 1 85124 306 2
The Flora Graeca is one of the most extraordinary botanical publications of all time. The spectacular quality of the botanical illustrations, the size of the publication (10 double folio volumes), its cost on publication (over GBP 620 in 1830) and the lengths to which people went to see it all added to the Flora's reputation.
Indeed, there were so few copies of the first printing - just twenty five - that some people were skeptical that the book existed! This book summarizes the story of the Flora Graeca enterprise, profiling the leading characters, John Sibthorp and his celebrated illustrator Ferdinand Bauer, and charting their eastern Mediterranean adventures; the scientific and artistic aspects of the publication and its printing history.
It also looks at the horticultural legacy of Sibthorp's voyages and the plants he brought back to England, such as Crocus flavus ssp. flavus collected in Turkey, now popular in its own right as one of the parents of a popular garden hybrid, 'Golden Yellow', and Cyclamen persicum collected in Cyprus, now one of the most widely grown autumn-flowering species and the parent of many of the garden cyclamens. Heavily illustrated, the book brings together images of Sibthorp's specimens (looking remarkably fresh after 180 years) and illustrations from the original watercolours and the engravings preserved in Oxford.

NO Focus: A role for Nitric Oxide in the Cereal Killer Magnaporthe grisea
Mary Frances Illes, Pari Skamnioti and Sarah Jane Gurr
Department of Plant Sciences, University of Oxford, Oxford, OX1 3RB, UK.
Cereals are man’s most important food crops, indeed rice forms the staple diet of half the world’s population. Yet 18% of the world’s rice harvest, and 13% of the wheat harvest are lost to disease caused by fungal pathogens, such as the devastating Magnaporthe grisea, the rice blast fungus. To design fungicides that disrupt the fungal lifecycle without compromising plant or consumer health requires a detailed understanding of the biochemical signalling pathways that drive pathogen differentiation and infection of the host.
The free radical nitric oxide (NO) is small and simple, yet it mediates some of the most intricate and significant signalling functions known. In animals, it acts in neurotransmission and regulation of blood pressure, and is induced during the inflammatory response. In plants, NO affects development, can protect against drought and salinity, and may contribute to the induction of an immune response. As yet, little is known about the functions of NO in fungi; this work investigates its roles in M. grisea.
Analysis of the M. grisea genome identified four nitric oxide synthase (NOS) genes with high sequence homology and similar domain structure to animal NOSs. Quantitative real-time RT-PCR traced the expression profiles of these genes over a time-course of development of M. grisea: from germination of the fungal spore and growth of the emerging germ tube to differentiation of the specialized infection cell (the appressorium) and penetration of host leaves. The transcript profile of one gene, NOS3, was upregulated 200-fold at the time of appressorium maturation and penetration, compared with levels seen in the ungerminated spore. Chemical inhibitors of NOS enzymes inhibited the formation of appressoria, signifying a role for NO in their development. However, the small signalling molecule cAMP allowed normal appressoria formation in the presence of NOS inhibitors, suggesting cAMP acts downstream of NO in a signalling pathway. To permit deeper investigation of the importance of NO in M. grisea development, a nos3 knockout mutant was generated. It forms very few appressoria and consequently causes radically fewer disease lesions on leaves. However, exogenous cAMP “rescues” the mutant to normal wild type development. NO therefore appears to be pivotal to pathogenicity in the rice blast fungus, offering us a new insight towards the rational design of fungicides.

Work from Sweetlove lab published in PNAS
The Sweetlove lab have established a physiological role for the Arabidopsis mitochondrial uncoupling protein. The catalytic function of uncoupling proteins has been previously established - they reside in the inner mitochondrial membrane and transport protons, dissipating the proton gradient across this membrane. However, until now, the physiological role of this uncoupling of mitochondria was not understood. Using a knockout mutant of AtUCP1, Sweetlove et al. were able to demonstrate that uncoupling protein is required in leaves to maintain a high flux through the photorespiratory pathway. Knockout of UCP1 reduces photorespiration leading to a decreased photosynthetic assimilation rate and a decrease in growth.

Research by Tsiantis group on the molecular basis of leaf development published in Nature
Nature 437, 1022-1026 (13 October 2005)
SERRATE coordinates shoot meristem function and leaf axial patterning in Arabidopsis
Stephen P. Grigg, Claudia Canales, Angela Hay and Miltos Tsiantis
Leaves of flowering plants are determinate organs produced by pluripotent structures termed shoot apical meristems. Once specified, leaves differentiate an adaxial (upper) side specialized for light capture, and an abaxial (lower) side specialized for gas exchange. A functional relationship between meristem activity and the differentiation of adaxial leaf fate has been recognized for over fifty years, but the molecular basis of this interaction is unclear. In Arabidopsis thaliana, activity of the class I KNOX (KNOTTED1-like homeobox) genes SHOOTMERISTEMLESS (STM) and BREVIPEDICELLUS (BP) is required for meristem function but excluded from leaves, whereas members of the HD-Zip III (class III homeodomain leucine zipper) protein family function to promote both meristem activity and adaxial leaf fate. Here we show that the zinc-finger protein SERRATE acts in a microRNA (miRNA) gene-silencing pathway to regulate expression of the HD-Zip III gene PHABULOSA (PHB) while also limiting the competence of shoot tissue to respond to KNOX expression. Thus, SERRATE acts to coordinately regulate meristem activity and leaf axial patterning.
