摘　　要：WRKY转录因子家族是植物中广泛存在、目前发现最大的转录因子家族之一;参与很多信号转导网络,调控多种植物发育和防御等进程。随着植物全基因组测序技术的兴起,全基因组鉴定和分析WRKY基因家族变得可能。2003-2006年,此类研究主要集中在模式生物拟南芥和水稻中。随着其他植物基因组测序的完成和公布,全基因组鉴定和分析WRKY基因家族的研究报道日益增多,这些研究不仅分析了各个植物WRKY家族的系统进化,而且用实时定量PCR、微阵列芯片、转录组RNA测序等新技术大规模研究了它们涉及到的生物学功能。主要综述了全基因组鉴定和分析WRKY基因家族的研究进展。WRKY transcription factors are one of the largest families of transcriptional regulators found widely in plants. They form integral parts of signaling networks that modulate many plant developmental processes and plant defenses. With the rise of whole-genome sequencing technology in plant, genome-wide identification and analysis of WRKY family became possible. From 2003 to 2006, these studies mainly focused on model organisms Arabidopsis thaliana and Oryza sativa. Then following the accomplishment and publication of other plant genomes, growing research on genome-wide identification and analysis of WRKY family have been published. Especially after 2013, the trend is now turning into a gusher. They not only analyze the phylogenetic evolution on various plant WRKY gene families, but also performed large-scale studies involving in the biological functions by new technologies such as real-time quantitative PCR, microarray, RNA transcriptome sequencing. This paper mainly reviewed the recent researches on genome-wide identification and analysis of WRKY family.
