Abstract

The diversity of endophytic bacteria and fungi of V. amurensis grape plants growing in the suburbs of Vladivostok in the summer and autumn periods of 2018-2020 was analyzed. About 600 strains of bacteria and 160 strains of fungi were inoculated from peripherally sterilized leaves and stems of V. amurensis. Isolated bacteria were representatives of 36 genera: Actinobacterium, Acinetobacter, Agrobacterium, Arthrobacter, Bacillus, Buttiauxella, Curtobacterium, Duganella, Erwinia, Enterobacter, Frigoribacterium, Frondihabitans, Klebsiella, Leclercia, Lelliottia, Methylobacterium, Microbacterium, Mucilaginibacter, Luteibacter, Lysinimonas, Pantoea, Paenibacillus, Parageobacillus, Pedobacter, Phyllobacterium, Plantibacter, Pseudomonas, Pullulanibacillus, Raoultella, Rhizobium, Sphingomonas, Staphylococcus, Stenotrophomonas, Streptomyces, Serratia, Xanthomonas. The largest number of strains were representatives of the genera Erwinia, Pantoae and Pseudomonas. Endophytic grape fungi were represented by 25 genera: Alternaria, Annulohypoxylon, Aureobasidium, Biscogniauxia, Cladosporium, Colletotrichum, Coniochaeta, Coprinellus, Davidiellaceae, Didymella, Discosia, Epicoccum, Fusarium, Hypoxylon, Neosetophoma, Nemania, Neurospora, Nigrospora, Paraphoma, Penicillium, Pestalotiopsis, Pestalosphaeria, Phoma, Trichoderma, Xylaria. The largest number of representatives were of the genus Didymella, Cladosporium and Colletotrichum.
