Response of microbial communities and physical and chemical properties in inoculated soils with <i>Fusarium oxysporum</i> Schl. F. sp. <i>Benincasae</i> to different root exudates resistant to fusarium wilt.

ABSTRACT: Wax gourd wilt (WGW) is a destructive soil-borne disease, and grafting pumpkin rootstocks offers effective and eco-friendly control. "Haizhan 1" pumpkin rootstock exhibits superior disease resistance compared to Cucurbita ficifolia, with root exudates improving soil microecology. However, the specific root exudate components involved in wilt resistance and their effects on soil microbial diversity remain unclear. In this paper, "Haizhan 1" pumpkin, Cucurbita ficifolia pumpkin and "Tiezhu 168" wax gourd are taken as rootstock materials to graft and obtain the five kinds of experimental subjects (H_T, B_T, H_H, B_B, T_T). Root exudates from five grafted combinations were analyzed by using metabolomics. Ten key metabolites that have direct fungicidal effects and indirect regulat
