As a kind of trans-acting factor, CBFs (C-repeat binding transcription factors) canbe induced by low temperature specifically. With specifically binding to the CRT/DRE (C-repeatdehydalration-responsive element) DNA regulatory elements, enhancing the induced expression ofcold or dehydration induced genes whose promoter regions contain the CRT/DRE regulatoryelements. As a result, a variety of stress-tolerant mechanisms are activated in plant, and then causingan array of physiological and biochemical modificat...
