Outline of Final Research Achievements

In plasma membrane, membrane rafts, in which lipids and proteins accumulate, exist. In this study, I identified immune proteins that transiently exist in membrane rafts during defense responses in rice and analyzed their function.　In NADPH oxidases that produce reactive oxygen species, OsRbohB and OsRbohH move to membrane rafts in response to chitin elicitor, and OsRbohB is essential for the resistance to rice blast fungus. In addition, our proteome analysis identified 63 proteins that transiently exist in membrane rafts after the treatment of chitin. In these proteins, I confirmed that 4 proteins localized in the plasma membrane
