摘　　要：株高是作物中的一种重要的农艺性状,通过矮化育种可减少倒伏,增强抗逆性并提高产量。油菜素类固醇是一种重要的新型植物激素,在植物生长发育过程中调控植物的株高。导致油菜素类固醇水平降低或油菜素类固醇信号传导受损的突变都会产生矮化。本文重点综述了各途径中导致矮化表型出现的突变基因。这些基因的发现,拓展了矮化作物育种的种质和遗传基础,为矮化种质资源创制和矮化新品种快速选育提供理论依据。Dwarfing is an important agronomic trait in crops,which can reduce lodging,enhance stress resistance and increase yield.Brassinosteroid is an important new plant hormone that regulates plant height during plant growth and development.Mutations that cause a decrease in Brassinosteroid level or impair Brassinosteroid signaling will produce a dwarf phenotype.This article focuses on the mutated genes that induce the dwarf phenotype in each pathway.The discovery of these genes has expanded the germplasm and genetic basis of dwarf crop breeding,and provides a theoretical basis for the creation of dwarf germplasm resources and rapid breeding of new dwarf varieties.
