For example, a small cysteine-rich protein SsSSVP1 in the necrotrophic phytopathogen Sclerotinia sclerotiorum may manipulate plant energy metabolism to facilitate the infection of S. sclerotiorum by interaction with QCR8, a subunit of the cytochrome b-c1 complex of mitochondrial respiratory chain in plants [39]. Here, UQCRQ is linked to infection.
