Characterization of a Secretory YML079-like Cupin Protein That Contributes to Pathogenicity.

causes devastating diseases in many agriculturally important crops, including oilseed rape and sunflower. However, the mechanisms of pathogenesis remain poorly understood. In this study, we characterized a YML079-like cupin protein (SsYCP1) from . We showed that SsYCP1 is strongly expressed and secreted during infection. infection was promoted by overexpression and inhibited by silencing this gene with synthetic double-stranded RNA. These results collectively indicate SsYCP1 as a putative effector protein that contributes to pathogenicity. These findings extend our understanding of effector-mediated pathogenesis and suggest a novel role for YML079-like cupin proteins in plant-pathogen interactions.
