Abstract:

ERF family is a major subfamily of plant-specific APETALA2/ethylene-responsive factor(AP2/ERF)transcription factor family. Its member structure is characterized by containing only one AP2/ERF domain composed of 58-60 amino acids. Most researches on the members of this family were focused on abiotic stresses such as cold and drought,and recent studies demonstrate that ERFs play an important role in resisting plant diseases and insect pests. These ERF subfamily members can bind to the GCC box element within the promoter region of their interactive genes,and activate or inhibit the expressions of these pathogenesis-related genes. Moreover,more researches confirmed that ERFs participate in salicylic acid(SA),jasmonic acid(JA),ethylene(ET),H2O2,and other hormone signaling pathways,and effectively coordinate different hormones to resist the invasion of pathogenic bacteria,and to improve plants’ resistance to disease and insect through mutual promotion/antagonism. This paper reviews the structure features of ERF transcription factors(TF),their regulatory mechanisms in different plants’ antibiotic stresses,and the latest progresses in improving plant resistance to diseases and insect pests by coordinating the interaction of different hormone signaling pathways. Finally,the paper prospects the application of ERF in plant disease resistance breeding.
