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.
