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)
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)
Same gene protects from 1 disease, opens door to another
Botanists at Oregon State University have discovered that a single plant gene can cause resistance to one disease at the same time it produces susceptibility to a different disease - the first time this unusual phenomenon has ever been observed in plants. view more (2007-08-29)
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)
Quick identification needed to save Florida's citrus industry from devastating disease
The recent discovery of citrus greening (huanglongbing) in samples collected from trees in South Florida poses a definite threat to Florida's $9 billion commercial citrus industry. view more (2005-09-15)
Why plants' soapy defences against disease don't always wash.
Natural soaps are an important weapon in the armoury that plants deploy to protect against disease attack, but a report today, in the international journal Nature, describes how disease-causing microbes can turn these plant defences to their own advantage. Scientists at the Sainsbury Laboratory (SL)[1] Norwich, UK, have discovered that fungi that... view more... (2002-08-19)
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)
Red alert! How disease disables tomato plant's 'intruder alarm'
How a bacterium overcomes a tomato plant's defences and causes disease, by sneakily disabling the plant's intruder detection systems, is revealed in new research out today (4 December) in Current Biology. view more (2008-12-05)
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...

Herbal alternative to farmyard antibiotics
Research at the University of Leeds into herbal remedies in the farmyard could soon see pigswill garnished with garlic and cows chewing on cinnamon-flavoured cud. With an EU ban on antibiotic growth promoters in animal feed from 2006, alternatives need to be found urgently. The use of plant extracts, once dismissed as quack science, is attracting... view more... (2004-01-26)
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...

Rot resistant wheat could save farmers millions
CSIRO researchers have identified wheat and barley lines resistant to Crown Rot - a disease that costs Australian wheat and barley farmers $79 million in lost yield every year. view more (2009-10-29)
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)
Grazing animals help spread plant disease
Researchers have discovered that grazing animals such as deer and rabbits are actually helping to spread plant disease - quadrupling its prevalence in some cases - and encouraging an invasion of annual grasses that threaten more than 20 million acres of native grasslands in California. view more (2008-12-30)
Vineyard weeds found to host Pierce's disease of grapes
New research just released in the September issue of Plant Disease suggests that weeds commonly found in California's wine country may enable the spread of Pierce's disease of grapes, one of the most destructive plant diseases affecting grapes. view more (2005-09-22)
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)
