An unexpected outcome of atmospheric CO2 enrichment
Unseen belowground interactions impact the composition of natural plant communities. Mycorrhizae, symbiotic associations between soil fungi and plant roots, help plants acquire soil nutrients but also drain substantial carbon from plants. Whether mycorrhizae help or hinder plant growth depends upon the balance between nutrient benefits and carbon... view more... (2003-05-22)
Whitefly spreads emerging plant viruses
A tiny whitefly is responsible for spreading a group of plant viruses that cause devastating disease on food, fiber, and ornamental crops, say plant pathologists with The American Phytopathological Society (APS). view more (2007-01-19)
Thale cress goes on the defensive
Thale cress has a complicated defence technique against insects and microorganisms that use the plant as a source of food. view more (2007-05-15)
Grazer diversity counteracts plant diversity effects on ecosystem functioning in seagrass beds
Several influential experiments have shown that high plant diversity enhances ecosystem productivity, animal diversity, and invasion resistance. Yet theory predicts that plant and herbivore diversity, which often co vary in nature, should have countervailing effects on ecosystem properties. In the July issue of Ecology Letters, Duffy, Canuel, and... view more... (2003-07-02)
Seed banks preserve plant diversity
'Some seed gene banks contain more higher plant species per square meter than anywhere else on the planet', write Simon Linington and colleagues of the Millenium Seed Bank, Kew, in the October issue of Biologist. This helps to 'ensure plant diversity is available long term for use in development or habitat restoration', they explain. Although... view more... (2003-10-02)
Catastrophic shift in species diversity and productivity of an ecosystem
Ecology and environmental management is largely predicated on the view that ecosystems respond to environmental changes in a smooth and straightforward way. However, in Ecology Letters, May, Schmitz reports on a long-term field experiment that may prompt a hard, critical look at this reigning view. In the experimental system, top predators... view more... (2004-05-04)
Hat Trick for University of Leicester Plant Biologist
A University of Leicester scientist has recently received the EMBO (European Molecular Biology Organisation) Young Investigator Award, the first UK plant biologist to be awarded this prestigious international prize. view more (2004-10-29)
EU Food Position Papers Published By SCI
A special issue of the Society of Chemical Industry (SCI) peer-reviewed Journal of the Science of Food and Agriculture (JSFA) is now available containing critical reviews produced within the European Union (EU) Concerted Action Nutritional Enhancement of Plant-based Food in European Trade (NEODIET) An international array of scientists have... view more...

UK joins world treaty to share vital plant resources
Vital food crops will be protected worldwide under a new international agreement which comes into force today. The UK is one of more than 50 countries committed to the International Treaty on Plant Genetic Resources for Food and Agriculture, which aims to improve food security and promote sustainable farming. The treaty aims to ensure that plant... view more... (2004-06-29)
Would you like gene chips with your salad ?
The first public release of plant gene chip information is being launched at the Society for Experimental Biology conference in Swansea on Friday 12th April. Scientists from the Nottingham Arabidopsis Stock Centre (NASC), part of a multi-million pound resource network, will announce a newly accessible plant gene chip database which is available... view more...

Possible new hope for crops battling parasitic infection
Scientists from Ghent University and VIB (The Flemisch Institute for Biotechnology) have demonstrated how nematodes, also known as roundworms, manipulate the transport of the plant hormone auxin in order to force the plant to produce food for them. view more (2009-01-16)
Fabled 'vegetable lamb' plant contains potential treatment for osteoporosis
The "vegetable lamb" plant - once believed to bear fruit that ripened into a living baby sheep - produces substances that show promise in laboratory experiments as new treatments for osteoporosis, the bone-thinning disease. view more (2009-10-15)
Smaller plants punch above their weight in the forest, say Queen's biologists
New findings from Queen's University biologists show that in the plant world, bigger isn't necessarily better. view more (2009-07-15)
University of Sussex launches world's first degree programme in 'seed banking'
Biologists are being offered the chance to help save the planet by enrolling in an innovative new postgraduate degree at the University of Sussex this autumn. Together with the world-renowned Royal Botanic Gardens, Kew, the University is to offer the world's first degree programme in 'seed banking', which includes strategies for safeguarding the... view more...

Drought sensitivity shapes species distribution patterns in tropical forests
Looking at a rainforest it's easy to see that there are hundreds of different tropical plant species that inhabit the forest. Although the patterns of plant distributions in tropical forests have been widely studied, the reasonings behind these patterns are not as well known. view more (2007-05-15)
'Dung of the devil' plant roots point to new swine flu drugs
Scientists in China have discovered that roots of a plant used a century ago during the great Spanish influenza pandemic contains substances with powerful effects in laboratory experiments in killing the H1N1 swine flu virus that now threatens the world. view more (2009-09-10)
Ironing out malnutrition
Two of the three keys are in place to unlock the secret to controlling and enhancing plant iron uptake. Scientists are poised to identify the final step in the process that could supply the world with iron-rich crops. Collaboration between American and French scientists has led to the identification of three key genes involved in iron uptake in... view more... (2001-04-02)
ISU researcher identifies genetic pathway responsible for much of plant growth
Researchers at Iowa State University have discovered a previously unknown pathway in plant cells that regulates plant growth. view more (2009-05-21)
Ecosystem consequences of a single, genetically based plant trait
Climate is often touted as the most important regulator of decomposition and nutrient cycling processes in forest ecosystems, however, in the forthcoming issue of Ecology Letters, Schweitzer and her research team from Northern Arizona University and the University of Wisconsin, USA, demonstrate that plant genes can have strong effects on the... view more...

Hormone clue to root growth
Plant roots provide the crops we eat with water, nutrients and anchorage. Understanding how roots grow and how hormones control that growth is crucial to improving crop yields, which will be necessary to address food security and produce better biofuels. view more (2009-07-08)
