Researchers discover primer to plant defense system
By identifying a novel compound that primes a plant's immune system, researchers at Oak Ridge National Laboratory and the University of Chicago may be on a path to developing disease-resistant plants. view more (2009-04-06)
UCR scientists identify stem-cell genes that help form plant organs
Plant stem-cells are master cells located at the tip of the stem and are part of a structure called the shoot apical meristem (SAM). Here, the stem cells-all clumped together-divide throughout the life of the plant to give rise to other cells, resulting in the formation of above-ground organs such as leaves, flowers, branches and stem. view more (2009-02-25)
Electricity from straw
Researchers have developed the first-ever biogas plant to run purely on waste instead of edible raw materials - transforming waste into valuable material. view more (2009-02-03)
Insects see crops clearly when the weeds have gone
All gardeners know that their plants have to compete against insects and weeds. We apply insecticides to protect plants from the munching hordes, and we apply herbicides, or hoe, to protect plants from weeds. But, according to Stan Finch and Rosemary Collier of Horticulture Research International, Wellesbourne, the latter is a bad move that... view more... (2003-06-05)
Less trouble at mill, thanks to earthworms
Waste from the textiles industry could with the assistance of earthworms and some animal manure become a rich compost for agriculture, according to a report in the International Journal of Environment and Pollution. view more (2009-07-16)
Global changes alter plant growth schedule
Any gardener knows that different plant species mature at different times. Scientists studying natural plant communities know this phenomenon allows species to co-exist by reducing overlap so there is less competition for limited resources. view more (2006-09-05)
Discovery in plant virus may help prevent HIV and similar viruses
In a study that could lead to new ways to prevent infection by human immunodeficiency virus (HIV) and similar organisms, Purdue University researchers have been able to genetically modify a plant to halt reproduction of a related virus. view more (2007-08-01)
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)
Nitrogen research shows how some plants invade, take over others
Biologists know that when plants battle for space, often the actual battle is for getting the nitrogen. view more (2009-07-07)
Drought limits tropical plant distributions, scientists at the Smithsonian report
Drought tolerance is a critical determinant of tropical plant distributions, researchers working at the Smithsonian Tropical Research Institute in Panama report in the journal Nature, May 3. view more (2007-05-03)
Newly defined signaling pathway could mean better biofuel sources
A newly defined biochemical pathway in plants may provide the scientific tools to design plants that will yield larger quantities of alternative transportation fuels than currently can be produced, according to Purdue University researchers. view more (2008-03-10)
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)
Dartmouth study contributes to research addressing malnutrition and iron deficiency
Dartmouth biologists are leading a research team that has learned where and how some plant seeds store iron, a valuable discovery for scientists working to improve the iron content of plants. view more (2006-11-03)
The largest leachate plant in Europe
Leachates are the dirty or contaminated waters from landfills, produced as a consequence of both the moisture already present in the waste as well as of rainwater contaminated on passing through the waste material. The leachate plant has a capacity for treating 350,000 cubic metres a year, equivalent to the amount of wastewater generated by a city... view more... (2004-02-25)
Alternatives to the use of nitrate as a fertiliser
In order to develop sustainable agricultural production, what is required is a study of nitrogenated sources as alternatives to the nitrates that predominate in agricultural soils and that have a greater contaminant capacity. view more (2006-04-19)
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)
Organic nitrogen gives new clue to biodiversity
Scientists have found that organic nitrogen is more important for plant growth than previously thought and could contribute to maintaining diversity in grasslands. view more (2006-04-12)
Too much water, fertilizer bad for plant diversity
Too much of multiple good things - water or nutrients, for example - may decrease the diversity of plant life in an ecosystem while increasing the productivity of a few species, a UC Irvine scientist has discovered. view more (2007-03-27)
Biotech cotton provides same yield with fewer pesticides
Arizona farmers receive the same yield/acre, use fewer chemical insecticides and maintain insect biodiversity when they plant the biotech cotton known as Bt cotton, according to new research. view more (2006-05-02)
Saharan dust storms sustain life in Atlantic Ocean
Research at the University of Liverpool has found how Saharan dust storms help sustain life over extensive regions of the North Atlantic Ocean. view more (2008-07-21)
