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.
Highlights
Grapes are one of the most sought-after and economically important crops in the world
Juice was isolated from peripherally sterilized leaves, stems, berries, and seeds of V. amurensis under sterile conditions, which was subsequently pulverized on dishes with universal nutrient media R2A (Reasoner and Geldreich, 1985) and potato dextrose agar (PDA) (Neogene, UK)
During the analysis of the sequences, it was demonstrated that the isolated bacterial strains of wild grapes V. amurensis were from 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
Summary
Grapes are one of the most sought-after and economically important crops in the world. This plant is quite susceptible to the effects of the external environment and diseases of various etiologies. The causative diseases agents of the European-Asian group of grapes based on the species Vitis vinifera L. mainly growing on the territory of European states are well known. They study which microorganisms inhabit different parts of the V. vinifera grape plant [4] using metagenome sequencing, investigate the difference between the composition of microorganisms of healthy and diseased plants [5], identify which microorganisms are capable of suppressing the growth of pathogenic microorganisms [6]
