Prior Infection by <i>Colletotrichum spinaciae</i> Lowers the Susceptibility to Infection by Powdery Mildew in Common Vetch.

ABSTRACT: Anthracnose (Colletotrichum spinaciae) and powdery mildew (Erysiphe pisi) are important diseases of common vetch (Vicia sativa) and often co-occur in the same plant. Here, we evaluate how C. spinaciae infection affects susceptibility to E. pisi, using sterilized and non-sterilized field soil to test the effect of resident soil microorganisms on the plant's immune response. Plants infected with C. spinaciae (C⁺) exhibited a respective 41.77~44.16% and 72.37~75.27% lower incidence and severity of powdery mildew than uninfected (C^-) plants. Moreover, the net photosynthetic rate, transpiration rate, and stomatal conductance were higher in the C^- plants than in the C⁺ plants prior to infection with powdery mil
