Metabolite-mediated responses of phyllosphere microbiota to powdery mildew infection in resistant and susceptible black currant cultivars.

ABSTRACT: Plant-metabolite-microbe interactions play essential roles in disease suppression. Most studies focus on the root exudates and rhizosphere microbiota to fight soil-borne pathogens, but it is poorly understood whether the changes in phyllosphere metabolites can actively recruit beneficial microbes to enhance disease resistance. In this study, the differences of phyllosphere microbial communities and key leaf metabolites were systematically explored in resistant and susceptible black currant cultivars related to powdery mildew (PM) by integrating microbiome and metabolomic analyses. The results showed that the diversity and composition of microbiome changed, as highlighted by a reduction in microbial alpha-diversity and beta-diversity of susceptible cultivars. An increasing fungal network co
