Pathway found that lets mosquitoes fatten up, slow down for winter

... day-length environments to either impose a dormancy cycle or to prevent their shift to diapause. Some ... suggested the insulin signaling pathway affects dormancy in the roundworm and fruit fly. These are ... used by lots of organisms to regulate their dormancy period, Denlinger said. Warmer temperatures ...

Warming climate threatens California fruit and nut production

About winter ... state that lasts through late fall and winter. In order to break dormancy and resume growth, the trees must receive a certain amount of winter ...

Stowers Institute's Hawley Lab identifies factors responsible for restart of meiotic cycle

... appear in the Dec. 4, 2007 issue of PLoS Biology. The long period of dormancy that interrupts the process that parses out the correct number of ... state until the female reaches sexual maturity.

Mechanism for regulation of growth and differentiation of adult muscle stem cells is revealed

... regeneration, which is a natural response to injury and disease, environmental cues cause adult muscle stem cells (satellite cells) to shift from dormancy to actively building new muscle tissue. Although the signaling pathways controlling muscle regeneration are fairly well known, how these signals ...

Genetic snooze button governs timing of spring flowers

Mosquito genes explain response to climate change

... that the mosquito has changed genetically in response to recent, rapid climate change and now uses shorter, more southern day lengths to initiate dormancy in a landmark study that appeared in the Proceedings of the National Academy of Sciences (Dec. 4, 2001). The new study ?funded by the National ...

Scientists discover that ancient genes dictate flowering, fall bud set

... northern latitudes compared to those from southern latitudes. Because winter arrives earlier at northern latitudes, trees need to set bud and enter dormancy earlier than trees at more southern latitudes. The article concludes that the CO and FT genetic pathway is key to understanding adaptation to ...

Where have all the butterflies gone?

... This winter's weather conditions may have a lot to do with the drop in numbers. The early winter was mild, with not enough cold to end the winter dormancy or "diapause" of most butterflies, so they did not emerge to take advantage of early warm weather in February. Then March turned cold and wet, wiping ...

Sandia work launched on space shuttle shows live cells influence growth of nanostructures

... Jeff Brinker. Groups of such long-lived cells may also serve as models to investigate how tuberculosis bacteria survive long periods of dormancy within human bodies. En masse, they also may be used to generate signals to repel harmful bacteria from the surfaces of surgical tools like ...
