Transcription factor SsFoxE3 activating SsAtg8 is critical for sclerotia, compound appressoria formation, and pathogenicity in Sclerotinia sclerotiorum.

ABSTRACT: Sclerotinia sclerotiorum, the notorious necrotrophic phytopathogenic fungus with wide distribution, is responsible for sclerotium disease in more than 600 plant species, including many economic crops such as soybean, oilseed rape, and sunflower. The compound appressorium is a crucial multicellular infection structure that is a prerequisite for infecting healthy tissues. Previously, the Forkhead-box family transcription factors (FOX TFs) SsFoxE2 and SsFKH1 were shown to play a key regulatory role in the hyphae growth, sexual reproduction, and pathogenicity of S. sclerotiorum. However, little is known about the roles of SsFoxE3 regulating growth and development and pathogenicity. Here, we report SsFoxE3 contributes to sclerotium formation and deletion of SsFoxE3 leads to reduced formation of
