Abstract

Abstract: 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.

Key words: WRKY, genome-wide identification and analysis, phylogenetic evolution, expression pattern
