UQCRQ and infection: The cysteine-rich small protein SsSSVP1 in Sclerotinia sclerotiorum induce plant cell death when interacting with QCR8, a subunit of cytochrome b-c1 complex, and disturbs the localization of QCR8 in mitochondria, suggesting that SsSSVP1 manipulate plant energy metabolism to facilitate the infection of S. sclerotiorum [27].
