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.
