高等植物WRKY转录因子家族的演化及功能研究进展
Evolution and Gene Function of WRKY Transcription Factor Families in Higher Plants
摘要
Abstract
WRKY transcription factors are one of the largest transcriptional regulator families in higher plants.The WRKY proteins possess one or two unique DNA-bind domains with nearly 60 amino acids composed of conserved signature WRKYGQK,which bind specifically to the W-box elements in the promoter of the downstream target genes and thus direct the temporal-and spatial-specific expression of the designated genes.Here,to overview the molecular phylogenetics and gene function of WRKY in higher plants,we performed phylogenetically analysis for complete WRKY families in six representative plant species,and reviewed the research progresses on WRKY in the recent two decades.Our review mainly focuses on the biological functions of WRKY TFs in response to biotic and abiotic stresses as well as plant growth and development,providing a comprehensive summary of the functions of WRKY transcription factor family.关键词
