: Insights into an Emerging Rice Pathogen

Abstract

False smut of rice, caused by , has become one of the most important diseases in rice-growing regions worldwide. The disease causes a significant yield loss and imposes health threats to humans and animals by producing mycotoxins. In this review, we update our understanding of the pathogen, including the disease cycle and infection strategies, the decoding of the genome, comparative/functional genomics, and effector biology. Whereas the decoding of the genome unveils specific adaptations of the pathogen in successfully occupying rice flowers, progresses in comparative/functional genomics and effector biology have begun to uncover the molecular mechanisms underlying virulence and pathogenicity. We highlight the identification and characterization of the produced mycotoxins and their biosynthetic pathways in .The management strategies for this disease are also discussed. The flower-specific infection strategy makes the pathogen a unique tool to unveil novel mechanisms for the interactions between nonobligate biotrophic pathogens and their hosts.
