Research advances on NAC transcription factors regulating plant development and stress responses
Due to the sessile characteristics,plants often face various adverse environmental factors during growth and development.Thus,they have evolved different regulatory mechanisms to maintain growth,development,and to overcome the effects of stresses.NAC(NAM/ATAF/CUC)is one of the im-portant transcription factor families in plants,consisting of a highly conserved N-terminus and a relatively variable C-terminus.NACs regulate the flower organ development,flowering time,leaf senescence,fruit ripening,secondary cell wall formation,root development,and are also involved in plant responses to vari-ous biotic and abiotic stresses.This review summarizes the functions of NAC family members in growth,development and stress responses of plants,to provide a theoretical basis for further dissection of the molecular mechanisms and applications of NAC transcription factors.
