Researchers learn what sparks plant growth
A secret long held by plants has been revealed by Howard Hughes Medical Institute researchers. The new discovery, which builds on more than a decade of painstaking surveillance of cellular communication between different types of plant tissues, shows clearly for the first time how plants "decide" to grow. view more (2007-03-08)
The effect of transgenic nematode resistance on non-target organisms in the potato rhizosphere
A paper published today in the December Issue of Journal of Applied Ecology by Cowgill et al describes the results of small-scale field trials that were used to assess the effect of PI-expressing potatoes on non-target soil organisms. The impact of a currently used PCN management option, the nematicide, aldicarb, on soil organisms was also studied. view more (2002-11-26)
Protea plants help unlock secrets of species 'hotspots'
New species of flowering plants called proteas are exploding onto the scene three times faster in parts of Australia and South Africa than anywhere else in the world, creating exceptional 'hotspots' of species richness, according to new research published today in Proceedings of the National Academy of Sciences (PNAS). view more (2008-12-23)
Smithsonian scientists find evidence that could rewrite Hawaii's botanical history
Scientists at the Smithsonian Institution have discovered data that suggests one of Hawaii's most dominant plants, Metrosideros, has been a resident of the islands far longer than previously believed. view more (2008-04-16)
Genetic discovery could lead to drought-resistant plants
New knowledge of how plants "breathe" may help us breed and select plants that would better survive scorching summers, says a University of Toronto study. view more (2005-07-19)
Taking the P out of plants
Is there an alternative to using GM crops in agriculture to eradicate the need for applying excessive phosphate fertiliser? John Hammond of UK's Horticulture Research International thinks so. Working in collaboration with Nottingham University, he is developing a diagnostic test that tells when plants are low on phosphorus so they can be... view more... (2004-03-24)
Norwich scientist receives prestigious international science prize
"I am very pleased that the work of my group has been recognised by this award", said Professor David Baulcombe. "I am also delighted to see that research into plants has been acknowledged. It is often forgotten that plants are excellent models for many types of genetic and biochemical research. Beijerincks discovery of viruses in... view more... (2004-10-28)
Study explores plant phenotypic plasticity belowground
When we think of organisms actively searching for resources (foraging) we generally think of things like wolves stalking elk or butterflies finding flowers. Why don't we also think about plants growing roots through the soil? view more (2005-07-27)
Sunflowers that love heavy metal
Sunflowers take up uranium twice or even three times better than their maize and soybean counterparts, making them a top 'clean crop' for removing toxic metals from the environment. Scientists at the Centre for Pesticides and Environmental Research, Yugoslavia, studied growth and uranium uptake in sunflower, soybean and maize crops. Sunflowers... view more... (2001-04-01)
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)
Plants in the fourth dimension
As anyone who has suffered from jetlag knows, we have internal clocks that tell us when to sleep and wake, and we can be miserable when these are disrupted. view more (2008-07-01)
Study shows vitamin C is essential for plant growth
Scientists from the University of Exeter and Shimane University in Japan have proved for the first time that vitamin C is essential for plant growth. This discovery could have implications for agriculture and for the production of vitamin C dietary supplements. view more (2007-09-24)
Helping Tomatoes Cope With Stress May Be Good For Us
Scientists at the John Innes Centre (JIC)(1) and Institute of Food Research (IFR)(2), Norwich, have today reported the discovery and use of a gene that may help protect plants and humans against disease. The gene (HQT) was identified in tomato and is responsible for producing an antioxidant called chlorogenic acid (CGA). By increasing the... view more... (2004-04-26)
Getting plants to rid themselves of pesticide residues
Scientists in China have discovered that a natural plant hormone, applied to crops, can help plants eliminate residues of certain pesticides. The study is in the current issue of ACS' Journal of Agricultural and Food Chemistry, a bi-weekly publication. view more (2009-10-01)
If only the weeds would keep their genes to themselves
Family can be a blessing and a curse, and never more so than in the case of crop plants and their wild relatives. These wild and weedy relatives harbor unique and beneficial genes that may no longer be found in their cultivated siblings, but they also harbor genetic traits that farmers have intentionally selected against in their domesticated... view more...

Can a plant be altruistic?
The concept of altruism has long been debated in philosophical circles, and more recently, evolutionary biologists have joined the debate. view more (2009-11-11)
Sexual frustration: programmed cell death prevents plant inbreeding
Scientists have demonstrated the importance of programmed cell death in preventing inbreeding in plants, according to research published in Nature today. Researchers at the University of Birmingham School of Biosciences have found that self-incompatibility, an important mechanism in plants that prevents them fertilizing themselves with their own... view more...

The salt of life and genes
Mineral salts are essential for living organisms. To be precise, it is from these, living cells get their basic components, the ions. Common salt, for example, contains chloride and sodium ions which the cell uses to establish and maintain electrochemical balance with the environment. In order to achieve sodium equilibrium in animal cells, for... view more... (2003-04-16)
Plants tag insect herbivores with an alarm
Rooted in place, plants can't run from herbivores—but they can fight back. Sensing attack, plants frequently generate toxins, emit volatile chemicals to attract the pest's natural enemies, or launch other defensive tactics. view more (2007-05-10)
