We described the comparative genomic analysis to delineate the taxonomic relationship between the two Glutamicibacter species Glutamicibacter mysorens NBRC 103060T and Glutamicibacter nicotianae NBRC 14234T. Phylogenetic tree based on concatenated ribosomal protein marker genes showed both species clade together. The average nucleotide identity (ANI) values between G. mysorens NBRC 103060T and G. nicotianae NBRC 14234T ranged from 97.23 to 97.97%. Further, the average amino acid identity (AAI) between two strains were more than 97.61%. The ANI, AAI and in silico DNA-DNA hybridization (isDDH) data were higher than the threshold value for bacterial species delineation. The two strains have identical profile of fatty acids, sugars and lipid composition; and overall similar phenotypic characteristics. It therefore becomes evident that the two species actually belong to the same species. Arthrobacter nicotianae (Giovannozzi-Sermanni 1959) (Approved Lists 1980) and Glutamicibacter nicotianae Busse 2016 have priority over the names Arthrobacter mysorens (Nand and Rao 1972) (Approved Lists 1980) and Glutamicibacter mysorens Busse 2016, therefore we proposed that Glutamicibacter mysorens Busse 2016 is a later heterotypic synonym of Glutamicibacter nicotianae Busse 2016. The type strain is ATCC 15236T = CCM 1648T = BCRC (formerly CCRC) 11219T = CCUG 23842T = CDA 883T = CIP 82.107T = DSM 20123T = HAMBI 1859T = IAM 12342T = IFO (now NBRC) 14234T = IMET 10353T = JCM 1333T = LMG 16305T = NCIMB 9458T = NRIC 0153T.

系统基因组学分析表明，Arthrobacter mysorens Nand 和 Rao 1972（1980 年批准列表）和 Glutamicibacter mysorens Busse 2016 是 Arthrobacter nicotianae Giovannozzi-Sermanni 1959 和 Glutamicibacter mysorens Busse 1959 的异型同义词（Approved Lists 1980）（Approved Lists 1980）

我们描述了比较基因组分析，以描绘两种谷氨酸杆菌物种 Glutamicibacter mysorens NBRC 103060T 和 Glutamicibacter nicotianae NBRC 14234T 之间的分类关系。基于串联核糖体蛋白标记基因的系统发育树显示两个物种进化枝在一起。G. mysorens NBRC 103060T 和 G. nicotianae NBRC 14234T 之间的平均核苷酸同一性 (ANI) 值介于 97.23 至 97.97% 之间。此外，两个菌株之间的平均氨基酸同一性（AAI）超过 97.61%。ANI、AAI 和计算机 DNA-DNA 杂交 (isDDH) 数据高于细菌物种划分的阈值。这两种菌株具有相同的脂肪酸、糖和脂质组成特征；和整体相似的表型特征。因此很明显，这两个物种实际上属于同一物种。Arthrobacter nicotianae (Giovannozzi-Sermanni 1959)（1980 年批准列表）和 Glutamicibacter nicotianae Busse 2016 优先于名称 Arthrobacter mysorens（Nand 和 Rao 1972）（批准列表 Glutamicibacter mysorens，因此 Glutamicibacter mysorens（Nand 和 Rao 1972）（1980 年批准列表 Glutamicibacter是 Glutamicibacter nicotianae Busse 2016 的后来异型同义词。 类型菌株是 ATCC 15236T = CCM 1648T = BCRC（以前的 CCRC）11219T = CCUG 23842T = CDA 883T = CIP 82.107T = DSM230T = ISM23T = ISM2500 NBRC) 14234T = IMET 10353T = JCM 1333T = LMG 16305T = NCIMB 9458T = NRIC 0153T。
