植物转录因子DREB家族在非生物胁迫下的研究进展

biotic stress such as extreme temperatures, drought and heat shock conditions affect the survival, growth and reproduction of plants. To protect cells and adapt such conditions like these, transcription factors play an important role in plants. As a plant-specific transcrition factors, the DREB (dehydration-responsive element-binding protein) family members could activate the expression of stress-responsive genes via specific binding to the dehydration-responsive element/C-repeat (DRE/CRT) cis-acting element in their promoters. In this view, we discuss the functions and regulations of two major types of DREBs, DREB1/CBF and DREB2 under abiotic stress. In the foreseeable future, we hope to lay a foundation for breeding and improvement of stress-resisted plant.
