ABSTRACT
A Gram-stain-negative, facultatively anaerobic, motile bacterial strain, designated gBX10-1-2T, was isolated from symptomatic bark of Populus×euramericana canker in China. Phylogenetic analysis based on its 16S rRNA gene sequence showed that the novel isolate belonged to the genus Brenneria, and shared the highest sequence similarity to Brenneria nigrifluens LMG 2694T (98.3â%). In the phylogenetic trees based on the four housekeeping genes sequences, the novel strain formed a separate branch different from B. nigrifluens LMG 2694T, indicating that the novel strain should be classified as a novel species. The genome sequence-derived average nucleotide identity (ANI) values between the novel isolate and B. nigrifluens LMG 2694T, Brenneria roseaesubsp. roseae FRB 222T and Brenneria roseaesubsp. americana FRB 223T were less than 85â%, lower than the proposed species boundary ANI cut-off value (95-96â%). The DNA G+C content was 56.2 mol%, and the main fatty acids were C16ââ0, C16ââ1ω7c, C18ââ1ω7c and C17ââ0cyclo. Based on the phenotypic and genotypic characteristics, strain gBX10-1-2T represents a novel species of genus Brenneria, for which the name Brenneria corticis sp. nov. is proposed. The type strain is gBX10-1-2T (=CFCC 11842T=KCTC 42840T).
