中文摘要：

有遗传，生物化学，和 proteomics 研究的联合途径极大地推进了我们在 Arabidopsis 发信号的 brassinosteroid (BR ) 的理解。然而在米饭， monocot 并且也的模型植物重要庄稼植物，发信号的 BR 是也没被描绘在 Arabidopsis。由前面、反向的遗传的最近的研究识别了保存的很多任何一个或表明小径的米饭 BR 的特定的部件，把新想法带进表明规定机制的 BR。BR 水平或 BR 敏感的基因操作建立了 BR 研究成就的大意义改进米饭产量。

英文摘要：

Combined approaches with genetics, biochemistry, and proteomics studies have greatly advanced our understanding of brassinosteroid （BR） signaling in Arabidopsis. However, in rice, a model plant of monocot and as well an important crop plant, BR signaling is not as well characterized as in Arabidopsis. Recent studies by forward and reverse genetics have identified a number of either conserved or specific components of rice BR signaling pathway, bringing new ideas into BR signaling regulation mechanisms. Genetic manipulation of BR level or BR sensitivity to improve rice yield has established the great significance of BR research achievements.
