摘　　要：由于固着生长的特性,植物在生长发育过程中会遭遇各种不利环境的影响,因此植物发展出复杂的调控机制来抵御胁迫危害。油菜素内酯(brassinosteroid,BR)是一类甾醇类植物内源激素,广泛参与植物生命周期中各种生命活动的调节。近年来,植物BR生物合成、代谢及信号转导过程相关研究已取得重要进展。油菜素唑抗性因子(brassinazole resistant,BZR)作为BR信号通路中特有的一类转录因子,在该通路中发挥重要作用。本文概述了植物BZR家族成员的基本结构及其生物学功能,重点阐述了BZR在植物非生物胁迫应答和生长发育中的调控作用,特别归纳了油料作物BZR研究进展,并对一些尚未明确的问题进行了探讨,旨在为深入理解BR介导的分子调控网络、改良作物抗逆性并提高作物生产力提供理论依据。Plants are often affected by various adverse environments during growth and development as a result of being sessile. Therefore, plants have developed sophisticated regulatory mechanisms to cope with the stresses.Brassinosteroid(BR) is a type of endogenous steroidal phytohormones, which regulate various biological processes throughout plant’s life-cycle. Brassinazole resistant(BZR) family is a plant-specific transcription factor family and plays essential roles in BR signaling pathway. In this paper, we summarized structure of BZR family proteins and their biological functions in BR signaling pathway especially in oil crops. The unsettled issues in BZR-associated research are discussed and prospected. It was to provide an overview of BR-mediated molecular regulatory networks, and facilitate genetic improvement of oil crop stress resistance and yield.
