Research Progress on Infection Cycle and Conidia Pathogenicity of Ustilaginoidea virens(cooke)Takahashi
Rice false smut is a rice panicle disease caused by infection of Ustilaginoidea virens(cooke)Takahashi,which occurs widely in China.This disease affects seriously rice yield and grain quality.To study the process of Ustilaginoidea virens(cooke)Takahashi infestation and its pathogenic mechanism will provide theoretical basis for the prevention and control of rice false smut.In this paper,the research progresses on the infection process and infection cycle,conidia formation and germination and related genes,as well as molecular interaction mechanism between Ustilaginoidea virens and rice were reviewed,and some suggestions for further research were put forward.
