Outline of Final Research Achievements

Plants have a multitier surveillance system that recognizes invading microbial pathogens using plasma membrane-localized and intracellular immune receptors. An RBOH (respiratory burst oxidase homolog) protein plays a key role in plant innate immunity. In this study, we found that a plant virus hijacks a host ROS generating enzyme RBOH for its multiplication. We also found that a plant virus infection can interfere with host immune responses.
