摘 要: WRKY转录因子家族是植物中超级转录调控因子家族之一,均包含由60个高度保守的氨基酸组成的WRKYGQK和锌指结构。WRKY结构域能特异性地与靶基因启动子的(T)(T)TGAC(C/T)序列(W-box)相互作用,从而调控靶基因的表达。在拟南芥中共有74个WRKY家族转录因子成员,它们参与了拟南芥的生长发育、衰老、生物和非生物胁迫反应、防御反应等生理调控。研究就近年来国内外关于WRKY转录因子的结构及其调控功能进行了综述。

Abstract: WRKY transcription factor family is one of the largest families of transcriptional regulators in plants, which contains 60-amino acid domain, and the conserved sequence motifs are WRKYGQK and a zinc-finger motif. The WRKY domain binds specifically to the DNA sequence motif (T)(T)TGAC(C/T), which is known as the W box. There are 74 members of WRKY transcription factors in Arabidopsis thaliana. WRKY transcription factors appear to be involved in various physiological programs, including growth and development, senescence, biotic and abiotic stress responses, as well as defense responses. This paper reviews the progresses on the structure of WRKY transcription factors and the function in various phsyilogical programs.
