Аннотация: Pseudomonadota and Bacillota phyla dominated among cultivable bacteria; Proteobacteria, Actinobacteria, Firmicutes, Chloroflexi, Acidobacteriota, Verrucomicrobiota, Bacteroidota, and Crenarchaeota were detected by NGS. The endophytic communities differed at the genus level with dominating non-pathogenic Curtobacterium and Pseudomonas. Attached bacteria on the non-sterilized and surface-sterilized buds were observed. Bud-associated Methyllobacterium and Paenibacillus showed tryptophan-dependent biosynthesis of auxins. It strongly depended on the medium, with the lower IAA production in MS.Lilacs maintain a wide diversity of root-associated bacteria with a number of beneficial strains. The endophytic community is limited and varies among the cultivars. Bud-associated PGPB may survive during sterilization and reveal their growth-promoting activity by producing auxins, though optimization of plant-microbial interactions is needed.
