摘要
植物激素生长素调控植物生长发育及环境适应的多个过程,包括胚胎发育、器官发生和向性生长等.生长素发挥生物学功能主要依赖于经典的TIR1/AFB-auxin-Aux/IAA-ARF信号转导途径.其中,由4个保守结构域组成的典型Aux/IAA蛋白作为TIR1/AFB的共受体在生长素信号转导过程中发挥关键作用.然而,近年来发现缺乏保守结构域的非典型Aux/IAA蛋白也参与生长素的应答与调控作用.该文从蛋白结构、生物学功能及参与生长素信号转导等方面综述了非典型Aux/IAA蛋白的研究进展,探讨和展望了非典型Aux/IAA蛋白的研究方向.
Abstract
The plant hormone auxin regulates many processes of plant growth and development,including embryonic development,organogenesis,and tropism,as well as environmental adaptation.To perform these functions,auxin mainly depends on the typical TIR1/AFB-auxin-Aux/IAA-ARF signaling pathway.In this pathway,the canonical Aux/IAA proteins composed of four conserved domains play a key role in auxin signaling as co-receptor with TIR1/AFB.Recently,some non-canonical Aux/IAA proteins lacking conserved domain(s)were also found to be involved in the auxin response.This review focuses on the research advances of non-canonical Aux/IAA proteins on their structure,biological function and roles in auxin signal transduction,and discusses the future research directions of these proteins.
