Hybrid grass may prove to be valuable fuel source

..., requires little water and minimal fertilizer and thrives in untilled fields, Heaton said. In untilled fields, various wildlife species make their homes in the plant's leafy canopy and in the surrounding undisturbed soil. Illinois researchers have found that Miscanthus grown in the state has greater crop ...

Microbe has huge role in ocean life, carbon cycle

...nt cell - and yet it dominates life in the oceans, thrives where most other cells would die, and plays a huge role in the cycling of carbon on Earth. In nature, apparently, bigger is not always better. In a publication today in the journal Science, scientists outlined the growing knowledge about SAR11, a ...

Genetic defenders protect crops from fungal disease

...s that attacks barley, and Erysiphe pisi, one that thrives on the leaves and pods of pea plants. "Disabling just three genes allowed the pea powdery mildew to reproduce as well on Arabidopsis as it does on its normal host," Somerville remarked. "Thus, the resistance barriers limiting the growth of inappropr...

Bacteria that cause tooth decay able to survive without important biochemical pathway

...eptococcus mutans, the decay-causing organism that thrives in many a mouth, can do just fine without it. The findings, reported this month in the Proceedings of the National Academy of Sciences, have rocked the cellular biology scientific community, which has long considered the pathway to be crucial. The r...

Patterns in genome organization may partially explain how microbial cells work

... more primitive microorganisms, including one that thrives in boiling hot springs, also exhibit patterns in their genomes that are highly nonrandom. "This high degree of organization of prokaryotic genomes is a complete surprise, and this finding carried many implications that biologists might not have cons...

Researchers develop flood-tolerant California rice

..., the primary food for more than 3 billion people, thrives in standing water, it dies if it is completely submerged for more than four days. Water covering the rice plant reduces the plant's oxygen and carbon dioxide supplies, affecting photosynthesis and respiration. Submerged, the plants lack the gases nee...

Bacteria can help predict ocean change

... of bacteria are not interchangeable and that each thrives under predictable conditions and at predictable times. Conversely, the kinds and numbers of bacteria in a sample can show where and when it was taken. "I could tell you what month it is if you just got me a sample of water from out there," Fuhrma...

Ready, set, mutate?and may the best microbe win

... heat-loving bacteria G. stearothermophilus, which thrives at up to 73 degrees Celsius (163 F). Shamoo and graduate students Rafael Couñago and undergraduate Stephen Chen used a mutant strain of the microbe that was unable to make a key protein that the bacteria needed to regulate its metabolism at high temp...

New flood-tolerant rice offers relief for world's poorest farmers

...f poor rice farmers around the world. While rice thrives in standing water, like all crops it will die ifcompletely submerged for more than a few days. The development andcultivation of the new varieties is expected to increase foodsecurity for 70 million of the world's poorest people, and may reduceyield ...

Discovery could aid fight against cystic fibrosis infection

... susceptible to PA," Mougous said. "The bacterium thrives in the excess mucus that accumulates in their lungs. Once a PA infection in a CF patient's lung has been established, these hardy bacteria are difficult or impossible to clear, which over many years eventually results in the death of the patient. Our...

New moth variety disarms plants guarded by selenium

...'s elemental defense. The new moth variety in fact thrives on plants containing highly toxic selenium levels and, in contrast to related varieties, was not deterred from either laying eggs or feeding on the plant. Furthermore, the researchers found that a selenium-tolerant wasp (Diadegma insulare) in turn pa...

Mine runoff continues to provide clues to microbial diversification

...gues at ORNL describe the bacterial community that thrives in what amounts to sulfuric acid. Their work set the stage for the latest development because it provided the first large-scale proteome dataset for a real-life microbial community with a limited number of members. Of particular interest to DOE is...
