摘要: Phaeomoniella chlamydospora is a tracheomycotic fungus that colonizes the xylem of grapevines (Vitis vinifera L.), causing wood discoloration, brown streaking, gummosis, and necrosis, which negatively affect overall health, productivity, life span vines. Current control strategies to prevent or cope with P. infections are frequently ineffective. Moreover, it unclear how fungicides commonly applied in vineyards against downy powdery mildew agents mycobiome, including pathogens such as chlamydospora. In this study, we used next-generation sequencing assess effects foliar spray inorganic (copper oxychloride sulfur), synthetic (penconazole fosetyl-aluminum), natural (Blad) currently mildews. The subjects our investigation were (i) resident (ii) early colonization by consortium fungal endophytes (ACEA1), (iii) success chlamydospora, (iv) planta interaction between ACEA1, under greenhouse conditions, rooted grapevine cuttings cv. Cabernet Sauvignon. data obtained suggest mycobiome affected different fungicide treatments. addition, composing ACEA1 varied response fungicides, relative abundances some taxa being overrepresented underrepresented when compared control. comported significant changes composition, was greatly Blad, decreased abundance pathogen 12-fold (4.9%) (60.7%) other presence also considerably co-inoculated into plant reaching 13.9% 2.0%, depending on treatment applied. This study shows sprayed mildews have an effect non-target fungi colonize endosphere grapevines. We two potential fight namely, Blad use ACEA1. Further studies confirm these results required.
