摘　　要：油菜素甾体(brassinosteroids,BRs)是植物界普遍存在的一类多羟基化的植物甾体激素,不仅调节植物的生长发育过程,还参与植物对生物和非生物胁迫的响应。概述了BRs的生物合成途径以及信号转导途径,重点阐述了BRs参与非生物胁迫应答的分子机制,展望了BRs未来的研究方向,为深入理解BRs介导的非生物胁迫调控网络、提高作物抵抗非生物胁迫的能力提供理论依据。BRs(brassinosteroids)are polyhydroxylated phytosteroid that are common in the plant kingdom,and they not only regulate plant growth and development,but also play important roles in biotic and abiotic stress responses.Here the biosynthesis and signal transduction pathways of BRs are summarized,focusing on the molecular mechanism of BRs in plant response to abiotic stress response.And the future research direction of BRs is prospected.It provides theoretical basis for further understanding BR-mediated regulatory network of abiotic stresses and improving stress resistance of crops to abiotic stresses.
