Research Abstract

Rice blast is the most important disease or rice. Blast is usually controlled by agrochemicals and resistant cultivars, but knowledge about molecular mechanisms of rice resistance toward blast is limited. This study aimed to elucidate the molecular mechanism of rice blast resistance by analyzing interaction of rice blast resistance gene Pia and blast virulence gene AVR-Pia. Results of this study indicated that AVR-Pia gene is started to be expressed before the penetration into rice cells, and after the secretion, AVR-Pia protein forms homodimer, and detected by rice Pia gene product. This study will contribute to further understanding of rice-rice blast interaction, which is the first step of resistance induction.
