It is well known that plant genotype can regulate phyllosphere fungi at the species level. However, little about how varieties shape fungal communities in phyllosphere. In this study, four types of maize with various levels resistances to Exserohilum turcicum were subjected high-throughput sequencing reveal properties influences composition communities. The dominant genera for all Alternaria different relative abundances, followed by Nigrospora. Hierarchical clustering analysis, non-metric multidimensional scaling and similarity analysis confirmed significantly clustered into respective variety they inhabited. findings from Redundancy Analysis (RDA) indicated both resistance leaf chemical constituents, including nitrogen, phosphorus, tannins, flavonoids, major drivers determining Among these factors, was found be most influential, phosphorus. co-occurrence network highly resistant had higher complexity, integrity stability compared others varieties. a conclusion, constituents play role shaping community. work proposes link between assembled within pathogenic infection.
