Genomics portends the next revolution in agriculture
...ut of an organism to confer or promote a desirable trait
in a plant or animal, as is the case in GMO technology, the advent of genomics portends an even more powerful tool as scientists can now rapidly comb the thousands of genes in a genome to see which genes are at work. "The key is you can detect funct...
Deep Green spawns Deep Gene and Deep Time to continue work toward a complete tree of life for the green plants
... two closely related plants, one with a particular trait
and one without, to help them reduce the number of genes they need to look at to isolate those responsible for the trait. "Ideally, you could narrow the search down to probably just a few genes from thousands," he said. Alternatively, ancestor-descen...

was lacking. With genomics, however, scientists take a different approach. They use automated equipm...
Oncogene spawns further mutation in breast cancer study
...athway involving ras mutations. Synergy is a nice trait
to find among human endeavors, said Chodosh, But synergy among oncogenes makes my work a little more complex. According to Chodosh, cancer is basically the progress of uncontrolled cell reproduction. The mechanisms that cells use to divide go out of ...
New species arise more quickly than previously believed, UMass researcher finds

influences mating success, Hendry says. "Deeper-bodied males gain access to more females during mating but, in a river with a strong current, a deep-bodied male would be inefficient hydrodynamically, and would have a more difficult time, so river fis...

Purdue researcher finds space fertile arena for gene transfers

introduced. On earth, less than 1 percent of the control group showed the trait. "The rate of transient expression in a space environment was more than tenfold over the success rate of a comparable terrestrial experiment," Vierling says. Those experi...

...er habitat with a few inches of water." Another trait
that could help these fish successful colonize southeastern waterways is that swamp eels are air breathers, enabling them to survive long dry spells. In fact, said Curnutt, their use of air is so efficient that the eels can readily migrate short dist...
'Biomedical switch' regulates how cells stick together and communicates

is jointly regulated by the rigidity of the surrounding environment and cellular contractility. Using digital microscopic analysis combined with fluorescent proteins expressed in live cells, the team captured time-lapse "movies" revealing the mobilit...
Researchers show that proteins can transmit heritable traits

from one generation of yeast cell to another. Their latest work builds on the discovery of a protein that transmits a genetic trait, a finding that hints at the presence of a menagerie of undiscovered protein-based "genetic elements" that may have ...
