Grants

Major international push to maximise bioscience research to help world’s poorest farmers

The Department has been awarded two grants from the BBSRC-led programme 'Sustainable Crop Production Research for International Development' (SCPRID).

The aim of Julian Hibberd's grant "Wild rice MAGIC" (£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.

The aim of the project "Modelling and manipulation of plant-aphid interactions: A new avenue for sustainable disease management of an important crop in Africa" (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. Post Doctoral Research Fellow job is available for this grant (closing date 30 January).

Labmash a smash hit

Plant Sciences played host to 28 secondary school students who live in care, as part of the University’s "Realise" project that encourages students to stay in 16+ education. Students took part in a shortened practical adapted from our first year undergraduate "Physiology of Organisms" course.

"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.

Feedback comments included: "It's like CSI Miami!" "ABSOLUTELY BRILLIANT! I loved it - I'm considering studying Biology for uni" and "Very interactive, friendly and well supported".

Thanks go to Barbara Landamore, teaching staff and volunteer post-grads.

Paper published in PNAS

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.

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.

Plant power, 19 May at the Botanic Garden

To kill and to cure, to make and to mend, to bewitch and beware, discover
The Power of Plants
as the Botanic Garden hosts first Fascination of Plants Day on
Saturday 19 May 2012

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.

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.

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.

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.

Yoan Coudert won 3rd Prize in the University of Cambridge Research Image Competition

Branching moss.
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.

Neil Dalchau awarded 2011 Tansley Medal


The 2011 Tansley Medal has been awarded to Neil Dalchau from Microsoft Research, Cambridge. Neil has made important discoveries that provide invaluable insights into the regulation of the circadian clock in Arabidopsis thaliana using a combination of mathematical modeling and experimental intervention. Most revealing among these has been the demonstration that components of the circadian clock are sensitive to sucrose and that the GIGANTIA gene is essential for its perception (Dalchau et al., 2011).

Neil was a graduate student in the Signal Transduction Group with Dr Alex Webb.

Doug Bailey

I’m sorry to have to tell you that Doug Bailey died peacefully at his home on Monday (16th Jan) after a long battle with cancer. Doug was a Director of Research at INRA and was seconded as an INRA Visiting Fellow to work in the Department in the Epidemiology & Modelling Group.

Those who knew Doug well will remember him as a kind and generous colleague. He was an accomplished researcher with a remarkable ability to communicate the excitement and value of epidemiological research to experimenters, theoreticians, farmers and regulators. Others in the Department may not know much about Doug’s background and his contributions to research and I add an all too brief summary below. We shall miss him dearly.

Doug began his career in the University as a technical assistant in my group in the Dept of Applied Biology, transferring to Botany/Plant Sciences in 1989. He had previously worked at the Plant Breeding Institute and before that as a tractor driver for Pemberton Farms. Doug was an accomplished and much sought-after footballer with opportunities to play for major clubs but he decided instead to concentrate on a career in science, reading for a part-time degree at Anglia, from which he graduated with a first. This was followed by a part-time PhD with the Open University while continuing to work in the Epidemiology Group. Doug then completed several successful postdoc positions with us before being head-hunted by INRA to establish epidemiological programmes first on vine diseases in Bordeaux and then on soil-borne diseases in Rennes.

Doug was a remarkable experimenter with the rare gift of understanding how to interface experimentation with mathematical models in order to gain insight into the mechanisms of how diseases spread and to test that insight rigorously in both microcosms and in extensive field experiments. Doug produced seminal work on the roles of primary and secondary infection in the spread of disease. He pioneered research on disease-induced host growth, in which he showed how low levels of infection stimulate plants to over-compensate for infection by producing more leaves or roots that act as ‘stepping-stones’ to favour disease spread. He also carried out a series of elegant experiments on scaling from individual to population behaviour in epidemics. These experiments led to the first successful experimental test of percolation theory to predict disease invasion. Doug’s microcosm experiments in which he could study not only epidemiological mechanisms but the variability amongst replicate epidemics also led to new insights into how to improve the effectiveness of biological control of soil-borne pathogens by exploiting knowledge of the mechanisms and potential for variability. Doug’s research on primary and secondary infection in take-all of wheat was adopted by the Home Grown Cereals to explain the much–studied phenomenon of take-all decline in cereals, with related work impacting on sugar-beet diseases.

Doug’s work, matched with his enthusiasm and ever-friendly and helpful support, have endeared him to many and left a lasting legacy in laboratories here and in France and amongst many colleagues around the world.
