On 20<sup>th</sup> June, Dr Robert Bradburne, Head of Science in the
Sustainable Land Management and Livestock Farming team at Defra, visited
the department. He gave a talk and led a discussion with graduate
students about working as a scientist in government, and about the role
of science in policy making.<br />
<br />
This visit followed a twelve-week placement by PhD student Robin
Thompson (from the Theoretical and Computational Epidemiology group) at
Defra, working as part of the UK-China Sustainable Agriculture
Innovation Network (SAIN) team. Robin spent the first six weeks of the
placement writing six papers that were tabled at the recent SAIN
Governing Board meeting in Beijing, covering a range of issues including
future challenges to sustainable agriculture in the UK and the role of
agriculture in social and economic development. The papers were used as
a basis for discussion about ongoing UK-China collaboration in
sustainable agriculture. Robin spent the second six weeks of the
placement putting the decisions made at the Beijing meeting into
practice, and learning more about the interface between science and
policy by, for example, spending a day shadowing Chief Scientific
Advisor at Defra, Ian Boyd.<br />
<br /><a class="internal-link" href="https://www-falcon.csx.cam.ac.uk/site/PLANTSCI/images/news/2013-06-20-defra" target="_self" title=""></a>
The talk on 20<sup>th</sup> June was an excellent introduction
to working at a scientist in government, and was inspirational for
graduate students interested in such a career. Robin’s twelve-week
placement was undertaken as part of the BBSRC Professional Internships
for PhD Students (PIPS) scheme.<br />

independent Tree Health and Plant Biosecurity Expert Taskforce, chaired by
Professor Chris Gilligan, was established late last year to address the current
and emerging threats to the UK’s trees and plants. Working with an advisory

a number of initiatives aimed at minimising the risk of plant pests and

Chris Gilligan, chair of the taskforce and Professor of Mathematical Biology
and Head of the School of Biological Sciences at the University of Cambridge,
said: “The UK needs to be better prepared for threats to plant health. In the

task force scientists believe that the threats have increased because of
globalisation in trade and travel and the subsequent escalation in volume and
diversity of plants and plant products entering the UK, all of which
potentially harbour plant pests and pathogens. Once established, pests and
pathogens can wreak havoc on biodiversity, timber and crop production, the
landscape and, in certain circumstances, human health. (In addition to Chalara,
recent examples include horse chestnut leaf mining moth, oak processionary
moth, bleeding canker of horse chestnut and Dothistroma needle blight on

the remit was to focus on trees and related woody species, the taskforce noted

agricultural, horticultural and biomass crops, indigenous vegetation and
ornamental plants).<o:p></o:p></span></span></div>

there are numerous risk assessments for individual pests and pathogens at both
the national and European level. The taskforce recommends a single national
Risk Register for plant health. This new UK Plant Health Risk Register would
serve to identify and prioritise pests and pathogens that pose a threat to the
UK and to identify what actions must be taken should the threat
materialise. <o:p></o:p></span></span></div>

of globalisation, more and more people and goods are travelling greater
distances at an increasingly greater rate. As a result, there is a significant
increase in the risk of introducing non-native pests and pathogens. In order to
minimise the risks of introduction at the border, the taskforce has made
several recommendations regarding the import of trees and other plants. They
propose that no plant material for personal use be imported from outside the
EU.<o:p></o:p></span></span></div>

import of live plants, foliage, branches and other plant parts has seen a 71
per cent increase since 1999, dramatically increasing the risk a pathogen or
pest might be introduced. Therefore they also propose the Plant Passport
scheme, which currently only applies to some plants associated with pests and
pathogens, be strengthened and also applied to seeds as a means of ensuring
traceability (showing all ports of calls within the EU and last port before
entry to the EU).<o:p></o:p></span></span></div>

University of Cambridge researchers, who have already been working closely with the government on the issue, will be an integral part of the initiative.
</p><p>
£2.4M of fast-track research funding has been awarded to gather an in-depth understanding of the ash dieback fungus and to provide genetic clues about some ash trees’ natural resistance to attack. Computer models will also be built to develop monitoring plans for the distribution and spread of the fungus, as well as charting how the disease might progress. This knowledge will help to fight the fungus and replace lost trees with those more able to survive.
</p><p>
<a href="http://www.plantsci.cam.ac.uk/research/chrisgilligan.html"><b>Professor Christopher Gilligan</b></a> with Drs <a href="http://www.plantsci.cam.ac.uk/research/nikcunniffe.html"><b>Nik Cunniffe</b></a> and <a href="http://www.plantsci.cam.ac.uk/research/gilligan/group/castle.html"><b>Matt Castle</b></a> at the University of Cambridge and <a href="http://www.rothamsted.ac.uk/PersonDetails.php?Who=555"><b>Dr Frank van den Bosch</b></a> at Rothamsted Research, have been awarded £1M in funding to develop and test mathematical, computer-based models to predict the spread of ash dieback in the UK, to improve strategies for surveillance and monitoring of the disease, and to inform ways to stop or delay the spread.
</p><p>
Professor Chris Gilligan, Head of the Epidemiology and Modelling group welcomed the award, saying: “This timely award will enable us to solve some of the fundamental epidemiological questions that underpin the ability of the UK to respond quickly and effectively to pest and disease incursions. The project is also designed to provide practical advice about the spread, where to sample, and the potential for management of ash dieback to policy makers and stakeholders throughout the course of the project.”
</p><p>
The ability to predict the future spread of an epidemic is crucial for designing both efficient sampling strategies and effective management plans. The use of models, informed by the most up-to-date data, allows different potential surveillance and management strategies to be explored in advance so the most effective ones can be identified and put into practice.
</p><p>
Specifically, using computational models for the spread of a pathogen provides a way to integrate information from the different strands of research (such as what environmental conditions are suitable for infection and how much of the ash tree population is resistant). This framework will allow management questions, such as “given the uncertainties involved, what control strategies would be effective?”, to be explored prior to the implementation of any given management program.
</p><p>
Dr Castle said: “This is an exciting opportunity for us; the award will allow us to build upon our existing modelling capabilities and explore even more sophisticated techniques for investigating the dynamics and future spread of ash dieback. This in turn will place us in an even stronger position to provide practical management advice.”
</p><p>
Dr Cunniffe said: "This award will allow us to develop epidemiological techniques and models applicable not only to ash dieback, but also to threats to our trees that we may face in the future."
</p><p>
The models will build on preliminary work by the Cambridge group to model the initial incursion of ash dieback and other diseases. Models of the patterns, causes, and effects of the disease will link with geographical information systems to predict the spread of disease across the UK landscapes.
</p><p>
The research will help inform where the disease is most likely to occur, where it will spread most rapidly and cause most damage, and where and when mitigation strategies should be most effectively used to slow or halt the spread. It will also help to answer key questions about monitoring the disease, such as: how to detect the disease in new areas early enough to control it; where to sample to find new outbreaks efficiently; and how we know if the disease is absent from an area.
</p><p>
The project will also look at how diseases might spread due to industries and trades involving trees and through atmospheric dispersal.
</p><p>
In addition to Cambridge, funding has been awarded to the Nornex consortium that brings together tree health and forestry specialists with scientists working with state-of-the-art genetic sequencing, biological data and imaging technologies to investigate the molecular and cellular basis of interactions between the fungus and ash trees.
</p><p>
Genome sequences of up to 30 samples of the fungus from the UK and Europe will rapidly help to acquire in-depth genetic information to shed light on the infection process. These data will reveal clues to the origins of the disease and provide genetic ‘markers’ to allow the spread of different strains of the fungus to be followed. Genetic data will also provide direct insights into the nature of the fungus.
</p><p>
The consortium will obtain information about how the disease spreads by studying infection in climate-controlled growth facilities, tracking the fungus as it colonises the plant. This vital information will help to develop effective disease control strategies.
</p><p>
The project will also uncover how some ash trees can partially resist attack. About 2% of Danish trees appear to ward off the disease but little information on the genetic basis for this is known. Genetic data from these trees will be compared to susceptible trees to find variations in their genetic codes. By identifying these differences, genetic makers can be developed to help breeders produce more resistant trees.
</p><p>
BBSRC Chief Executive <a href="http://www.bbsrc.ac.uk/organisation/structures/executive/chief-executive.aspx"><b>Professor Douglas Kell</b></a> said: “This agile funding response will ensure we improve our understanding of this devastating tree disease as quickly as possible. Little is known about the fungus, why it is so aggressive, or its interactions with the trees that it attacks. This prevents effective control strategies. These grants will enable the UK’s world-leading bioscience community to speed up the response to tackling the disease directly. It will also help us to understand and harness the ways in which some ash trees can defend themselves naturally.”

<p>As part of their annual global operations conference, AB Sugar invited members of the CambPlants Initiative to an afternoon of talks, posters and discussions surrounding how the company could respond to challenges and opportunities posed by global developments.
</p><p>
Dr Bhaskar Vira (Geography) gave an overview of the Strategic Initiative in Global Food Security and issues around political economy, such as land- and resource-grabbing; Prof Howard Griffiths (Plant Sciences) talked about water stress, carbon concentrating mechanisms and genetic innovation in crop plants, and Prof Paul Dupree (Biochemistry) highlighted opportunities for production of energy and chemicals from sugar and lignocellulosic by-products.
</p><p>
The talks were followed by a lively panel discussion and then a poster-pitch session. Dr Matthew Castle (Plant Sciences) introduced modelling of disease spread and mitigation options, Dr Matthew Davey (Plant Sciences) explained bioremediation and generation of value-from-waste using algae, Dr Paolo Bombelli (Biochemistry) and Ross Dennis (Plant Sciences) showcased the power of biophotovoltaics with the moss clock, and Dr Sue Barnard (Zoology and Tropical Biology Association) highlighted benefits of biodiversity conservation.
</p><p>
Throughout the afternoon, delegates captured ideas of how the new information could be incorporated into forward planning of the business, and follow-up conversations will take place with AB Sugar's innovation department.

<p>The Department has been awarded two grants from the BBSRC-led programme 'Sustainable Crop Production Research for International Development' (SCPRID).
</p><p>
The aim of Julian Hibberd's grant "<b>Wild rice MAGIC</b>" (£1.4M) is to increase drought tolerance and tolerance to bacterial and viral infections in domesticated rice using naturally existing variation in wild rice species. MAGIC is shortened from Multi-Advanced Generation Inter-Crossing. The research team includes not only scientists in Julian's lab in the Plant Sciences Department, but also colleagues at NIAB, IRRI in the Philippines as well as partners in Coimbatore, India and Tanzania.
</p><p>
The aim of the project <b>"Modelling and manipulation of plant-aphid interactions: A new avenue for sustainable disease management of an important crop in Africa"</b> (led at Plant Sciences by John Carr, Chris Gilligan and David Baulcombe) is to understand how changes in plant biochemistry caused by virus infection alter the behaviour of aphids (insects that transmit viruses between plants) and to see how this knowledge could be used to better protect crop plants against these insects and the viruses they transmit. In this £2M project the main focus is on bean and its viruses and the work will be carried out in collaboration with colleagues at Rothamsted and in Kenya and Uganda. <a href="http://ilrijobs.wordpress.com/2012/12/21/ilri-vacancy-post-doctoral-research-fellow-plant-molecular-biologist-closing-30-january-2013/"><b>Post Doctoral Research Fellow</b></a> job is available for this grant (closing date 30 January).

Students took part in a shortened practical adapted from our first year undergraduate "Physiology of Organisms" course.
<br /><br />
"Labmash; an introduction to enzyme induction" allowed students hands-on experience of extracting and assaying for nitrate reductase. It was great fun for staff and students alike.
<br /><br />
Feedback comments included: <i>"It's like CSI Miami!"</i> <i>"ABSOLUTELY BRILLIANT! I loved it - I'm considering studying Biology for uni"</i> and <i>"Very interactive, friendly and well supported"</i>.
<br /><br />
Thanks go to Barbara Landamore, teaching staff and volunteer post-grads.

<p>A new paper published in PNAS this week provides evidence for chloroplast pyrenoid formation in the green alga Chlamydamonas. The pyrenoid, once thought to be a starch-storage granule, is now recognized to be the centre of a carbon concentrating mechanism which turbocharges photosynthesis.
</p>
<p>Moritz Meyer, Maddie Mitchell and Howard Griffiths, in collaboration with colleagues in UNL Nebraska, have shown that modifications to the primary carboxylase, Rubisco, are responsible for pyrenoid formation. Specifically, it seems that two regions of the small subunit, the alpha helices, interact to allow Rubisco to aggregate into the pyrenoid, which also regulates CCM activity.</p>

<b>The Power of Plants</b>
<br />
as the Botanic Garden hosts first Fascination of Plants Day on
<br />
<b>Saturday 19 May 2012</b>
<br /><br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://2.bp.blogspot.com/-BCkIf76a2fU/T5VkV7KjjsI/AAAAAAAAAHY/X96SVvU4FCA/s1600/powerofplants.jpg" imageanchor="1" style="clear:right; float:right; margin-left:1em; margin-bottom:1em"><img border="0" height="194" width="200" src="http://2.bp.blogspot.com/-BCkIf76a2fU/T5VkV7KjjsI/AAAAAAAAAHY/X96SVvU4FCA/s200/powerofplants.jpg" /></a></div>
Plants have a unique talent: the ability to gather energy from the sun’s rays
travelling through space to synthesise their own food. This is the foundation of
all other life on earth, from the oxygen in our lungs to the medicines that keep
us healthy. They’re also some of the most stunning organisms on the planet,
and the most varied, adapted to every ecological niche across every
continent.
<br /><br />
On Saturday 19 May, plant scientists, biochemists, horticulturists and
representatives from the plant science industries will gather at the Botanic
Garden to share with visitors the power of plants for the first international
Fascination of Plants Day. Demonstrations and activities will run from
10.30am: science experiments will include balloons inflated by gases released
by fermenting plants, children can dress up as bees to collect nectar from
giant flowers to learn about pollination and there’ll be quizzes to match the
product to the plant. Plus the chance to test a laser remote sensing system –
the latest tool in forest conservation.
<br /><br />
The living world is a rich source of chemicals with many medicines, dyes,
flavourings and foodstuffs having their origins in compounds produced by
plants. Ampika Ltd, an ethical enterprise spinout of the University of
Cambridge, will be bringing a display about medicinal plants, including a new
anaesthetic gel derived from a plant found in the Peruvian rainforest, which is
currently under trial as a pain-relief treatment for toothache. The Botanic
Garden and Cambridge Crystallographic Data Centre will also be launching a
new Chemicals in Plants trail that identifies some of the poisonous, beneficial
(and occasionally both!) chemicals produced by plants.
<br /><br />
Launched under the umbrella of the European Plant Science Organisation,
the Fascination of Plants Day held at the Botanic Garden on 19 May will be a
day of interactive plant fun and demos that will also highlight the critical role
plant science plays in the social, environmental and economic landscape now
and into the future. The event is co-organised by the Cambridge Partnership
for Plant Science, a consortium that connects cutting-edge research
undertaken in the region with the business community that develops plants for
application in food, energy and other material uses.

Sibley Centennial Professor in Plant Molecular Genetics at The University of Texas at Austin and his colleagues, including David Baulcombe at the University of Cambridge, provide the first genetic evidence that seed development is controlled by maternally inherited "small interfering RNAs," or siRNAs.<br /><br /><a href="http://esciencenews.com/articles/2012/04/11/seed.size.controlled.maternally.produced.small.rnas.scientists.find"><b>Read more...</b></a><br /><br /><a href="http://www.pnas.org/content/109/14/5529.abstract?sid=16b6121b-c91e-4f47-9081-60b04b83c111"><b>Read the publication.</b></a>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-2787313723173041309.post-31989269995870738662012-04-10T09:24:00.003+01:002012-04-10T09:27:40.503+01:00Lighting up plant cells to engineer biology<a href="http://www.cam.ac.uk/research/files/2012/04/fernan-560x315.jpg"><img style="float:right; margin:0 0 10px 10px;cursor:pointer; cursor:hand;width: 560px; height: 315px;" src="http://www.cam.ac.uk/research/files/2012/04/fernan-560x315.jpg" border="0" alt="" /></a><br />Jim Haseloff's lab have developed a new technique for measuring and mapping gene and cell activity through fluorescence in living plant tissue. <br /><br /><a href="http://www.cam.ac.uk/research/news/lighting-up-plant-cells-to-engineer-biology/"><b>Read more...</b></a>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-2787313723173041309.post-3979934182928389642012-03-21T10:31:00.004+00:002012-03-21T10:34:06.020+00:00University Lectureship in the Department<a href="http://www.plantsci.cam.ac.uk/research/henderson/images/ianhenderson.jpg"><img style="float:right; margin:0 0 10px 10px;cursor:pointer; cursor:hand;width: 200px; height: 193px;" src="http://www.plantsci.cam.ac.uk/research/henderson/images/ianhenderson.jpg" border="0" alt="" /></a><br />David Baulcombe is pleased to announce that Dr Ian Henderson has accepted the offer of a University Lectureship in the Department and will take up the Lectureship duties when his Royal Society Fellowship finishes. <br /><br />Visit Ian Henderson's <a href="http://www.plantsci.cam.ac.uk/research/ianhenderson.html"><b>web page</b></a>.Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-2787313723173041309.post-20275336392290871172012-03-20T16:08:00.004+00:002012-03-20T16:18:11.191+00:00Yoan Coudert won 3rd Prize in the University of Cambridge Research Image Competition<a href="http://3.bp.blogspot.com/-SZd6NOlxSJU/T2irm4ele9I/AAAAAAAAAHA/Z1cnv74J1mE/s1600/branching-moss.jpg"><img style="float:right; margin:0 0 10px 10px;cursor:pointer; cursor:hand;width: 200px; height: 106px;" src="http://3.bp.blogspot.com/-SZd6NOlxSJU/T2irm4ele9I/AAAAAAAAAHA/Z1cnv74J1mE/s200/branching-moss.jpg" border="0" alt=""id="BLOGGER_PHOTO_ID_5722012011058265042" /></a><span style="font-weight:bold;">Branching moss.</span><br />Plant architecture diversification necessitated the evolution of branching mechanisms. The first land plants that appeared on earth about 450 million years ago were bryophyte‐like and had no branches but a single‐stemmed body. Mosses are the biggest group of extent bryophytes. The earliest branching plants were as tiny as mosses, exhibited a dichomomously branching stem but do not exist anymore except as fossils. The picture taken with a Nikon D80 camero and macro lens shows a natural variant of Bryum radiculosum with a branching shoot (left). Such variants represent a precious ressource to help us understanding how the switch from unbranched to branching growth happened several hundred millions years ago on earth. By reproducing artificially such developmental alterations in the lab, we aim at deciphering genetic alterations that have contributed to the earliest modifications of land plant architecture.Unknownnoreply@blogger.com1tag:blogger.com,1999:blog-2787313723173041309.post-32739161600317280002012-02-29T09:42:00.002+00:002012-02-29T09:51:46.975+00:00Professor B.A. AbeywickremaWe have been informed by Rohan H.
