摘要： Strains MS586(T)and MS82, which are aerobic, Gram-negative, rod-shaped, and polar-flagellated bacteria, were isolated from the soybean rhizosphere in Mississippi. Taxonomic positions of MS586(T)and MS82 were determined using a polyphasic approach. 16S rRNA gene sequence analyses of the two strains showed high pairwise sequence similarities (>98%) to somePseudomonasspecies. Analysis of the concatenated 16S rRNA,rpoB,rpoD, andgyrBgene sequences indicated that the strains belonging to thePseudomonas koreensissubgroup (SG) shared the highest similarity withPseudomonas kribbensisstrain 46-2(T). Analyses of average nucleotide identity (ANI), genome-to-genome distance, delineated MS586(T)and MS82 from other species within the genusPseudomonas. The predominant quinone system of the strain was ubiquinone 9 (Q-9), and the DNA G+C content was 60.48 mol%. The major fatty acids were C-16:0, C(17:0)cyclo, and the summed features 3 and 8 consisting of C-16:1 omega 7c/C-16:1 omega 6c and C-18:1 omega 7c/C-18:1 omega 6c, respectively. The major polar lipids were phosphatidylglycerol, phosphatidylethanolamine, and diphosphatidylglycerol. Based on these data, it is proposed that strains MS586(T)and MS82 represent a novel species within the genusPseudomonas. The proposed name for the new species isPseudomonas glycinae, and the type strain is MS586(T)(accession NRRL B-65441 = accession LMG 30275).
