“…Plant diseases can cause serious losses in yield. For example, anthracnose causes serious losses in the yield of velvetleaf ( Abutilon theophrasti ) [ 46 ], Chinese goldthread ( Coptis chinensis ) [ 37 ], alfalfa ( Medicago sativa ) [ 47 ], plum ( Pyrus spp.) [ 48 ], qing qian liu ( Cyclocarya paliurus ) [ 49 ], and other crops in China.…”

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 mildew. These differences were not recorded following powdery mildew infection. Additionally, the activities of superoxide dismutase, polyphenol oxidase, and catalase were higher in the C+ plants than in the C− plants. The resident soil microbiota did not affect the plant responses to both pathogens. By uncovering the mechanistic basis of plant immune response, our study informs integrated disease management in a globally important forage crop.
