Abstract: The regulation networks of gene expression mediated by transcription factors play important roles in plant responses to a range of environmental stresses. Transcription factors and their families identified to be involved in plant stress responses include APETALA2/EREBP, bZIP, WRKY, MYB, etc., which can constitute regulation networks to regulate the temporalspatial expression of each kind of related genes in plant stress responses. The genetic modifications of transcription factors and their regulation networks are increasingly becoming the effective approaches for understanding stress biology at system level, and a new way for enhancing the stress tolerance and resistance of plants.
