摘要
脱落酸(ABA)是植物生长发育和逆境适应过程中非常关键的植物激素。植物响应ABA信号转导过程由信号识别、转导及响应级联完成,其中心转导途径由ABA受体RCAR/PYR/PYLs、磷酸酶PP2Cs、激酶SnRK2s、转录因子和离子通道蛋白构成。蛋白磷酸化、泛素化、类泛素化和氧化还原等翻译后修饰在ABA转导途径中起重要作用。该文综述了翻译后修饰在ABA信号转导中的作用。
Abscisic acid(ABA) plays a key role in the growth, development and stress condition of plants. The process of plant response to ABA is completed by signal recognition, transduction, and response cascades. The core ABA signaling pathway consists of receptor RCAR/PYR/PYLs, phosphatase PP2 Cs, kinase SnRK2 s, and transcription factors and ion channel proteins. Post-translational modifications(PTMs) of proteins such as phosphorylation, ubiquitination, small ubiquitin-related modifier(SUMOylation) and redox modifications plays an important role in ABA signaling. This review focused on the role of modifications in the core ABA signaling pathway.
