- Abstract
The endophytic microbiome in seeds is closely related to the healthy development of seeds. In this study, the seeds of 11 highland barley varieties resistant or susceptible to powdery mildew were collected and subjected to amplicon sequencing to investigate the community, abundance and diversity of endophytic fungi. Endophytic fungi belonging to 4 phyla, 17 classes, 35 orders, 66 families and 107 genera were identified. Ascomycota, Basidiomycota and Mortierellomycota were the dominant phyla. Alternaria, Microdochium, Didymella Fusarium and Mycosphaerella were the dominant genera. The results of bioinformatics annotation show that among the 107 genera identified, 20 are specific in the seeds of resistant varieties and 50 are specific in the seeds of susceptible varieties. The fungal species diversity of susceptible cultivars was higher than that of resistant cultivars. This study provides a basis for further study on the relationship between endophytic fungi and resistance or susceptibility of highland barley to powdery mildew. It is hopeful to develop new strategies for disease prevention and control.
