摘要：

表皮毛作为大多数陆生植物表面的常见结构,不仅增强了植物抵抗干旱、紫外线和病虫害等不良环境因素的能力,其发育形成过程更是研究植物细胞命运分化的重要模型,因此对表皮毛发育调控机制的研究具有重要意义。目前,模式植物拟南芥表皮毛发育的一些关键基因已被克隆,表皮毛发育的调控机制也逐渐明了。但是有关水稻表皮毛发育机制的研究很大程度上不清楚,近年来一些水稻表皮毛相关基因陆续被鉴定或克隆,对其功能的研究也在不断深入。综述了水稻表皮毛相关基因的研究历程和进展,归纳了水稻表皮毛发育的调控途径,并展望了水稻表皮毛相关基因在光叶稻分子设计育种中的价值和应用前景。

Abstract:

As the common structures on the surface of most terrestrial plants,trichome not only enhance the ability of plants to resist adverse environmental factors such as drought,UV rays,pests and diseases,but also its development and formation process is an important model for the study of plant cell fate differentiation. Therefore,the research on development and regulation mechanism of trichome is of great significance. At present,some key genes for the development of the trichome in model plant Arabidopsis have been cloned,and the regulation mechanism of trichome development has been gradually uncovered. However,the research on the development mechanism of rice trichome is largely unclear. In recent years,some rice trichome-related genes have been identified or cloned one after another,and the research on their functions is also deepening. This review states the research history and progress of rice trichome-related genes,summarizes the regulation pathways of rice trichome development,and looks forward to the value and application prospects of rice trichome-related genes in molecular design breeding of rice trichome.
