摘要: 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。

Abstract: 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 identify 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 mutants in rice. In this review, recent advances in BR signaling in rice have been summarized, and future studies and applications were discussed.
