Genetic switch regulates a plant's internal clock based on temperature
Los Angeles CA (SPX) Sep 24, 2014 - Scientists have discovered a key molecular cog in a plant's biological clock - one that modulates the speed of circadian (daily) rhythms based on temperature. Transcription factors, or genetic switches, drive gene expression in plants based on external stresses - such as light, rain, soil quality, or even animals grazing on them. A team of researchers at USC has isolated one, called FBH1, ... more
