Research identifies protein that signals flowering in squash plants

...ature of the florigenic signal effectively, it was essential to utilize an obligate SD plant. In day-neutral plants, it is not possible to manipulate flowering by altering the daylength. By contrast, obligate SD plants will remain in the vegetative state until and unless inducing conditions (such as long night...

Discovery in orange cauliflower may lead to more nutritious crops

... causes the orange color and is a precursor to the essential nutrient vitamin A. While cauliflower and many staple crops have the ability to synthesize beta-carotene, they are limited partially because they lack a "metabolic sink," or a place to store the compound. Developing staple crops with more vitamin A...

Simulations unravel outer membrane transport mechanism

...irection of what’s called systems biology. This is essential because none of these proteins actually works alone. Each works in concert with many other things.” Tajkhorshid is also a professor of pharmacology in the College of Medicine and an affiliate of the Beckman Institute and the Center for Biophysics ...

A new plant-bacterial symbiotic mechanism promising for crop applications

... bacteria were found to have no nod genes, usually essential for nodulation. Bradyrhizobium consequently appeared to use mechanisms that involved other genes. This surprising result calls into question the universally recognized model of molecular communication that initiates the rhizobia-legume symbiosis. Thi...

Envisat captures first image of Sargassum from space

... not present on other ocean-colour sensors. It was essential to our detecting Sargassum," Gower said. "The MCI index has allowed us to find so many interesting things, including Sargassum and Antarctic super blooms. It really gives us a new and unique view of the Earth." Gower and King are now combining da...

Loss of stem cells correlates with premature aging in animal study

... cell reservoirs in adult mice. This gene, ATR, is essential for the body’s response to damaged DNA, and mutations in proteins in the DNA damage response underlie certain types of cancer and other disorders in humans. This work appears in the inaugural issue of Cell Stem Cell. “The reason we’re seeing the e...

New bacterium discovered -- related to cause of trench fever

...nella species respond to different drugs, so it is essential to explore further and pinpoint which one is involved.” The cat scratch bacteria and the one that brought down soldiers and AIDS patients can be reined in with the same antibiotic, but the Peruvian microbe is usually countered with different anti...

'Lucky 13' as new gene discovery offers further hope for childhood blindness

Researchers examine carbon capture and storage to combat global warming

...ke it viable. A policy framework, therefore, is essential for making carbon capture and storage economical, the Stanford researchers said. ''We need thousands of projects,'' Benson said. ''That's the kind of thing that will only happen if there are global policies to address these issues. That's the numb...

Small, self-controlled planes combine plant pathology and engineering

...e dynamics of plant pathogens in the atmosphere is essential for establishing effective quarantine measures, preventing the spread of plant disease, and mitigating potentially damaging events targeted at our nation’s agriculture and food supply.”...

New findings challenge established views on human genome

...y modifications in histones. “Teamwork was essential to the success of this effort. No single experimental approach can be used to identify all functional elements in the genome. So, it was necessary to conduct multiple, diverse experiments and then analyze them using multiple computational methods,” s...

454 sequencing identifies HIV drug resistance at early stage

...Life Sciences. “Ultra Deep Sequencing provides an essential tool for research on viral diseases and their treatments. The ability to use 454 Sequencing to detect rare viral mutations is a crucial research tool to better understand the early stages of HIV drug resistance.” It is estimated that 22 million pe...

Potent possibilities for parasite attack

...study provides a route to find those that might be essential to each species. One potential target is the CFAS gene that codes for cyclopropane fatty acid synthase, an enzyme that may be involved in producing components of the cell membrane. CFAS is present in the genomes of L. braziliensis and L. infantum,...
