Birds and bats sow tropical seeds

...es, which will ultimately provide living bait with crops of bat- and bird-dispersed fruits. Birds and bats living in nearby forests will fly to the bait to eat the fruit and will likely drop seed from forest species they carried. Fruit will be available all year, so a seasonal progression of seeds from lo...

Genetically modified maize not found in southern Mexico

...ified (GM) corn has not yet spread to native maize crops in southern Mexico. After analyzing tens of thousands of seeds from maize crops grown in 2003 and 2004, researchers from Mexico and the United States found no evidence of transgene...

Researchers find ways to turn manure into power

...e cattle; less irrigation water; and the switch to crops which use less water and require fewer nutrients. "Things are in reasonable shape now, but in 10, 20 or 30 years from now, we need to have alternate uses that are not based exclusively on land application," he said. Energy production has been resea...

Research team receives $7.5 million to study cassava

...ect to help improve one of the most important food crops in Africa, cassava. The Bill and Melinda Gates Foundation selected the BioCassava Plus project as a recipient of one of the foundation's "Grand Challenges in Global Health" program grants. Created two years ago, the goal of the $450 million program ...

Hope for Alzheimer's blossoms

Frank Marsh, Marketing Director, The Manufacturing Engineering Centre said: "Galanthamine has major investment potential. Furthermore, the potential for Wels...

Plant genes identified that can form basis for crops better adapted to environmental conditions

...lary root formation will enable the cultivation of crops that absorb water and minerals more efficiently. An important step toward a more environment-friendly, sustainable agriculture in a world whose population is growing while the land available for agriculture is diminishing. Tom Beeckman is in charge ...

Plant wounds trigger bacteria

...akes a large economic toll on fruit and wine-grape crops each year. "Mutant forms of Agrobacterium are also widely used in agricultural biotechnology for their ability to create transgenic plants containing new genes of scientific or economic interest," said Winans, a professor in Cornell's Department ...

Storing carbon to combat global warming may cause other environmental problems, study suggests

... larger water demands of growing trees rather than crops or pastures "dramatically decreased stream flow within a few years of planting," the authors wrote. Water use within existing tree plantations of all ages resulted in average stream flow reductions of 38 percent, with losses increasing as the trees ...

Bacterial protein mimics host to cripple defenses

That knowledge, gleaned from spinach and researchers on two continents, potentially could open the gate to advances in both plant and human health. The research, which appeared online this month in advance of regular public...

Scientists map one of biology's critical light-sensing structures

... it may be possible to engineer and introduce into crops phytochromes that respond to different wavelengths of light, or are more or less active. These changes, in turn, could allow plants to grow under different climate regimes or flower at different times of the year, for example. Gaining precise contro...

Plant defenses prompt bacterial countermeasure in the form of 'island' DNA excision
