油菜素甾醇（ brassinosteroids ，BR）是植物界广泛存在的一类植物激素，对植物生长发育的诸多方面有调节作用，也调控植物对环境逆境的胁迫响应。由于BR对与水稻产量相关的株高、籽粒大小、叶夹角、分蘖等性状产生影响，因而其合成和信号传递途径及如何调控BR信号以改善水稻农艺性状和产量，引起了业界的广泛关注。中国科学家在解析水稻BR信号传递因子方面，做出了突出的贡献。文章对近十余年来水稻BR信号传递的主要研究进展进行综述，并对未来可能的研究和应用领域及方向作了展望。

Brassinosetroids ( BR) is a class of ubiquitous plant hormones .They regulate diverse aspects of plant growth and development and resistance to environmental stresses .Since BR control several aspects of yield-related traits in rice, such as plant height , grain weight, leaf angle and tillering number , much attention has been paid to i-dentify the molecular components of BR biosynthesis and signaling , and to increase yield by genetic engineering BR biosynthesis or signaling .Chinese scientists have made significant progress in characterizing several BR signaling mu -tants in rice.In this review, recent advances in BR signaling in rice have been summarized , and future studies and applications were discussed .
