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.
在许多具有重要农业价值的作物中引发毁灭性疾病，包括油菜和向日葵。然而，致病机制仍知之甚少。在本研究中，我们鉴定了来自……的一种YML079样铜蛋白（SsYCP1）。我们发现SsYCP1在感染期间强烈表达并分泌。过表达促进了感染，而用合成双链RNA沉默该基因则抑制了感染。这些结果共同表明SsYCP1是一种有助于致病的假定效应蛋白。这些发现扩展了我们对效应物介导的致病作用的理解，并表明YML079样铜蛋白在植物与病原体相互作用中具有新作用。
