Polyphasic study of phytopathogenic bacterial strains associated with deep bark canker of walnut in Serbia revealed a new species, Brenneria izbisi sp. nov.

ABSTRACT: Serious outbreaks of walnut deep bark canker were observed on young walnut trees (Juglans regia L.) in two localities in the northern part of Serbia during 2020. From the symptomatic walnut tissues, two types of bacterial colonies were isolated, predominantly, light cream, circular and smooth colonies, as well as small, yellowish, mucoid and convex ones. PCR analysis and phenotypic assays suggested that the former group belongs to Brenneria spp., while the latter isolates were identified as Xanthomonas arboricola pv. juglandis. Within the Brenneria group, two strains were identified as Brenneria nigrifluens, while other 15 strains did not belong to any Brenneria species described so far. Therefore, we selected four representative strains of
