Abstract:WRKY proteins are one of the largest families of transcription factors(TFs) found in plants.Mem bers of this family play important bidirectional regulatory roles in plant growth and development,biomass formation,secondary metabolite synthesis,and response to biotic or abiotic stresses.This paper provided acomprehensive review of the structural features and classification of WRKY TFs in plants,as well as their biological functions in plant growth and development,secondary metabolite synthesis,and biotic and abiotic stresses unearthed in the last five years,and also provided an outlook on the subsequent related studies of WRKY family members,aiming to provide technical references for further excavation of plant WRKY family members and their biological function studies.
Key Words: WRKY;Growth and development;Secondary metabolism; Biotic stress;Abiotic stress
近年来,随着分子生物学在农业科学研究领域中的渗透和深入,人们对植物基因家族的关注越来越多,研究的深度和广度也逐渐增加。在高等植物中,WRKY蛋白作为一种最大的转录因子(Transcriptionfactor,TF)家族之一,广泛参与许多生物信号网络的调控,如植物生长、防御、攻击、代谢、毛状体和胚胎的形态发生、叶片衰老、生物量形成,以及对生物和非生物胁迫的响应等方面[1-5]。WRKY基因家族成员SPF1最初发现于甘薯[Ipomoeabatatas(L.)Lam.]中,并且受聚谷氨酸(Polyglutamicacid,PGA)和蔗糖的诱导进行表达。随着对植物分子方面研究的深入,目前已在245种植物中发现了不同数量的WRKY基因家族成员,探索出了其在植物中的作用。前期已经有文章详细叙述了自WRKY基因家族成员发现以来各个植物中鉴定出的WRKY基因及其数量,本文总结了近5年内分析鉴定出的WRKY基因7-66(图1)。在植物中,WRKYTFs作为激活或抑制因子,在各种同源或异源二聚体组合中形成一个TF网络,参与各种细胞质和细胞核过程,包括从细胞器或细胞质到细胞核的信号事件[5]。其中主要是WRKYTFs作为微生物或病原体相关分子模式触发免疫,或其效应物触发免疫,以此来正向或负向调控植物先天免疫系统的各个方面[6],主要作用过程有如下2个方面,一方面是WRKYTFs通过与其他蛋白(如受体、激酶或其他的TFs)相互作用进行交叉和自我调节[68-69],引起级联反应;另一方面是与其他反式元件结合,形成动态蛋白复合物,增强转录活性[70]。……
