Fourth wheat gene is key to flowering, climate adaptation

Posted by External 83 days ago General — A fourth wheat gene governing vernalization -- the biological process requiring cold temperatures to trigger flower formation -- has been identified, giving plant breeders one more tool for developing improved varieties of wheat that are adaptable to climate change.

Quasi-sexual gene transfer drives genetic diversity of hot spring bacteria

Posted by External 183 days ago General — New work from a multidisciplinary team of scientists used massive DNA sequencing of bacterial populations that grow in the hot springs in Yellowstone National Park to determine their genetic diversity and explore the underlying evolutionary dynamics. They found an unexpectedly high degree of sharing and exchange of genetic material between the tiny, green, photosynthetic cyanobacteria Synechococc Read More

Gene regulation underlies the evolution of social complexity in bees

Posted by External 198 days ago General — Explaining the evolution of insect society, with sterile society members displaying extreme levels of altruism, has long been a major scientific challenge, dating back to Charles Darwin's day. A new genomic study of 10 species of bees representing a spectrum of social living -- from solitary bees to those in complex, highly social colonies -- offers new insights into the genetic changes that acco Read More

Big-data analysis reveals gene sharing in mice

Posted by External 346 days ago General — Scientists have detected at least three potential hybridization events that likely shaped the evolutionary paths of 'old world' mice, two in recent times and one in the ancient past. The researchers think these instances of introgressive hybridization -- a way for genetic material and, potentially, traits to be passed from one species to another through interspecific mating -- are only the first Read More
