Metabolites-Mediated Response of Phyllosphere Microbiota to Rust Infection in Leaves of two Malus Species
Plants can recruit beneficial microbes to enhance their ability to against pathogens. However, in contrast to that the recruitment of microbes is regulated by the production of multiple root exudates, it remains largely underestimated whether changes in leaf metabolites caused by infectious pathogens could actively recruit beneficial microbes and thus combat foliar pathogens. Here, we integrated the Illumina amplicon sequencing and LC-MS analysis to systematically explore the dynamics of phyllosphere fungal and bacterial communities and key leaf metabolites in two crabapple species at six stages after infection of G. yamadae. We aimed to assess how phyllosphere microbial communities responded to G. yamadae infection during the rust colonization from the spermogonial to aecial stages; the key metabolites with significantly differently abundance in G. yamdaea infected leaves; how metabolites in G. yamadae infected leaves shape phyllosphere microbiomes assemblies and the co-occurrence patterns.
