油菜素甾醇类信号转导受体研究进展

摘 要:在植物和动物的生长发育过程中,甾醇和肽类激素被广泛地作为信号转导分子来使用。在植物中,油菜素甾醇类(BRs)信号由细胞表面受体激酶BRI1感知,该受体与动物的甾醇受体有明显的区别。对BR信号转导途径中组分的鉴定表明,该途径与其地动物和植物信号转导途径具有类似性。近来的研究证实番茄BRI1(tBRI1)能感知BR和肽类激素系统素。于是,关于受体-配体特异性的分子机制及进化的问题便产生了。本文就目前关于BRs信号转导中受体的研究进展作一综述。

Research progresses in the receptor of brassinosteroid signal transduction

Abstract:  Steroids and peptide hormones are widely used as signaling molecules in both plants and animals during growth and development. In plants, brassinosteroids (BRs) are perceived by the cell surface receptor kinase BRI1, which is distinct from the animal steroid receptors. Identification of components of the BR signaling pathway has revealed similarities to other animal and plant signal transduction pathways. Recent studies demonstrated that tomato BRI1 (tBRI1) perceives both BR and the peptide hormone systemin, raising new questions about the molecular mechanism and evolution of receptor杔igand specificity. This review focuses on recent progresses in the studies of the receptor of brassinosteroid signal transduction.
Key words:  brassinosteroids; signal transduction; receptor; ligand
