Genome info from 'plant destroyers' could save trees, beans and chocolate

...shington.More than 1 million native oak and tanoak trees have been lost to the disease. In addition to soybean and oak, Phytophthora species cause disease in avocado, coconut, papaya, pineapple, potato, strawberry and watermelon, to name a few. The pathogen also destroys an estimated 450,000 tons of cocoa...

Sequencing of the oyster mushroom genome

...degrading one, lignin being a component of wood of trees and other plants that form part of the second most important store of carbon in the Biosphere. The degradation of this compound is an essential step in the transformation of cellulose - the principal store for carbon ?into biofuel. Moreover, it has...

The subtleties of tropical forest demise

...." "We immediately notice when forests burn or trees come crashing down, but not when frogs disappear or plants stop reproducing because their critical pollinators have vanished," said Laurance. The 23 chapters in the book span much of the tropical world, including South America, Africa, South...

Plants give up answers in the war on bacteria

..., did $40 million in destruction to Michigan apple trees in 2000 alone and all but eliminated commercial pear crops in Michigan for that year. He also sees useful human health implications. Understanding that animal pathogens, like dangerous E. coli, cannot easily gain access inside the plant helps scien...

End of deforestation in view? Experts advance new way to size up global forest resources

Edge density key to controlling gypsy moth spread

...olina and west into Wisconsin where they defoliate trees and occasionally, cause extensive damage to northern deciduous forests. "We analyzed historical data on the spread of the gypsy moth in the U.S. and found that its invasion has been characterized by regular periods of rapid spread interspersed be...

Pressured by predators, lizards see rapid shift in natural selection

...rial predator is introduced, these lizards take to trees and shrubs, becoming increasingly arboreal over time. Losos and his colleagues hypothesized that immediately following a predator's arrival, longer-legged -- and hence faster-running -- Anolis lizards would be favored to elude capture. However, as th...

Researchers barcode DNA of Venice museum's vast fungi collection

...them available for the growth of plants, including trees and agricultural crops. "Without fungi, there would be no forests," Garbelotto pointed out. A large number of fungi are also plant pathogens and cause serious diseases of crops and trees, especially when transported to new areas of the world throu...

Bacteria that use radiated water as food

... as photosynthetic organisms, such as plankton and trees at Earth's surface, that capture sunlight energy ultimately to the benefit of everything and everyone else. In the deep subsurface case, Firmicutes species are the producers, capturing the energy of radiation-borne hydrogen gas to support microbial c...

Ancient birds flew on all-fours

...modern-day birds took to the skies by gliding from trees using primitive feathered wings on their arms and legs, according to new research by a University of Calgary paleontologist. In a paper published in the journal Paleobiology, Department of Biological Sciences PhD student Nick Longrich challenges the ...

Viral marker of human migration suspect

Researchers also said that this study and others by the group suggest that DNA viruses may not have a slow rate of evolution as previously thought, and that the viruses like JCV might in fact be evolving twice as fast. ...

UCSD study reveals how plants respond to elevated carbon dioxide
