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

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...

"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 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...
