Research on Advance of Rice False Smut Ustilaginoidea virens (Cooke) Takah Worldwide: III. Infection Cycle and Invasion Mechanism of U. virens and Rice Resistance to RFS

Abstract

In this part, the infection cycle and invasion mechanism of RFS, including the primary and secondary source of RFS infection. The factors affecting the disease occurrence and epidemiology, including the infection time and pathway, different conditions affecting the incidence of RFS, for example, the type of rice varieties and morphological characteristic, meteorological factors, environmental conditions, cultivation management, and amount of U. virens in the field. The mechanism of rice varieties’ resistance to RFS were also discussed, including morphological characteristics, and biochemical mechanism, resistance genes of rice.

Advances in False Smut of Rice and its Integrated Diseases Management: A Review

“…These ascospores produce conidia and hyphae of conidia which may infect panicle of rice plant at booting stage and spread over the surface of spikelets (Ashizawa et al, 2012). During asexual stage chlamydospore is responsible for secondary infection and germinates in soil and produces secondary conidia which results in secondary infection through wind and rain (Huang et al, 2019).…”
