Rhizopus rot is considered one of the most common diseases influencing global production and yield horticulture commodities. However, factors contributing to this pattern prevalence are uncertain. Here, we focused on R. microsporus , which known rely its endosymbiotic bacterium, Mycetohabitans produce toxins that interfere with plant development inhibit growth other fungi. We assessed impact symbiotic harboring endosymbiont as well fungus cured it on: (1) magnitude spoilage in tomato fruits, evaluated by Koch's postulate for pathogenicity, (2) shifts native communities endophytic fungi inhabiting these examined ITS rRNA gene metabarcoding (3) secondary metabolites generated communities, analyzed using multi-analyte LC-MS/MS. The pathogenicity test showed endobacterium-containing W2-50 was able cause fruit spoilage. This accompanied decreased relative abundance Alternaria spp. an increase Penicillium may have facilitated observed In conclusion, appeared facilitate spoilage, possibly through successful colonization or toxin endosymbiont.
