Pseudomonas populi sp. nov., an endophytic bacterium isolated from Populus euphratica Anwar, Nusratgul and Abaydulla, Gulsimay and Zayadan, Bolatkhan and Abdurahman, Mehfuzem and Hamood, Buayshem and Erkin, Raziya and Ismayil, Nurimangul and Rozahon, Manziram and Mamtimin, Hormathan and Rahman, Erkin,, 66, 1419-1425 (2016), doi = https://doi.org/10.1099/ijsem.0.000896, publicationName = Microbiology Society, issn = 1466-5026, abstract= A Gram-stain negative, aerobic, non-motile, short-rod-shaped bacterium, designated KBL-4-9T, was isolated from the storage liquid in the stems of Populus euphratica trees in Xinjiang, PR China. Strain KBL-4-9T grew at 4–45 °C (optimum 37 °C), 1–3 % (w/v) NaCl (optimum 1 %, w/v) and pH 5.5–9.5 (optimum pH 7.5). Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain KBL-4-9T belonged to the genus Pseudomonas and showed the highest 16S rRNA gene sequence similarity of 97.36 % to Pseudomonas pelagia CL-AP6T, followed by Pseudomonas xinjiangensis S3-3T (97.16 %), Pseudomonas sabulinigri J64T (97.15 %) and Pseudomonas xiamenensis C10-2T (96.47 %). Analysis of strain KBL-4-9T based on the three housekeeping genes, rpoB, rpoD and gyrB, further confirmed the phylogenetic assignment of the isolates. The DNA G+C content was 61.6 mol% (sd = 2.19). DNA–DNA hybridization with P. pelagia CL-AP6T, P. xinjiangensis S3-3T and P. sabulinigri J64T revealed 49.3 % (sd = 3.04), 41.2 % and 52.5 % (sd = 4.45) relatedness, respectively. The major cellular fatty acids of strain KBL-4-9T were C16 : 0, C12 : 0, summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c) and C17 : 0 cyclo. The major isoprenoid quinone was Q-9. The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and phosphatidylcholine. On the basis of phenotypic, chemotaxonomic and phylogenetic properties, strain KBL-4-9T is considered to represents a novel species of the genus Pseudomonas, for which the name Pseudomonas populi sp. nov. is proposed. The type strain is KBL-4-9T ( = JCM 19138T = CCTCC AB 2013069T = NRRL B-59988T)., language=, type=
