JF International Journal of Systematic and Evolutionary Microbiology, VO 63 IS Pt_1 SP 268 OP 273 DO https://doi.org/10.1099/ijs.0.033654-0 PB Microbiology Society, SN 1466-5034, AB Pseudomonas flectens Johnson 1956, a plant-pathogenic bacterium on the pods of the French bean, is no longer considered to be a member of the genus Pseudomonas sensu stricto. A polyphasic approach that included examination of phenotypic properties and phylogenetic analyses based on 16S rRNA, rpoB and atpD gene sequences supported the transfer of Pseudomonas flectens Johnson 1956 to a new genus in the family Enterobacteriaceae as Phaseolibacter flectens gen. nov., comb. nov. Two strains of Phaseolibacter flectens were studied (ATCC 12775T and LMG 2186); the strains shared 99.8 % sequence similarity in their 16S rRNA genes and the housekeeping gene sequences were identical. Strains of Phaseolibacter flectens shared 96.6 % or less 16S rRNA gene sequence similarity with members of different genera in the family Enterobacteriaceae and only 84.7 % sequence similarity with Pseudomonas aeruginosa LMG 1242T, demonstrating that they are not related to the genus Pseudomonas . As Phaseolibacter flectens formed an independent phyletic lineage in all of the phylogenetic analyses, it could not be affiliated to any of the recognized genera within the family Enterobacteriaceae and therefore was assigned to a new genus. Cells were Gram-negative, straight rods, motile by means of one or two polar flagella, fermentative, facultative anaerobes, oxidase-negative and catalase-positive. Growth occurred in the presence of 0–60 % sucrose. The DNA G+C content of the type strain was 44.3 mol%. On the basis of phenotypic properties and phylogenetic distinctiveness, Pseudomonas flectens Johnson 1956 is transferred to the novel genus Phaseolibacter gen. nov. as Phaseolibacter flectens gen. nov., comb. nov. The type strain of Phaseolibacter flectens is ATCC 12775T  = CFBP 3281T  = ICMP 745T  = LMG 2187T  = NCPPB 539T., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.033654-0
