Abstract:

Rice false smut caused by Villosiclava virens is a serious threat to limiting rice production. Due to difficult to identify the rice resistant varieties, limited information on reveal the resistance mechanism of rice. In this study we investigated defense-related gene expression of rice response from V. virens isolates. The results demonstrated that resistant material can be infected by V. virens isolates artificial inoculation when pathogenicity differs. The qRT-PCR analysis showed that defense genes expressions were activated at early developmental stages during the V. virens infection. Furthermore, V. virens isolates with low virulence can induce higher defense gene expression compared with the high aggressive isolates. This study will be helpful to uncover molecular mechanisms and signalling pathways to rice resistance to V. virens.
