“…The type species of this genus is Roseomonas gilardii (Rihs et al, 1993) and the species name was validated in the year 1998. "Roseomonas aceris" (Tonouchi and Tazawa, 2014), "Roseomonas baikalica" (Andreeva et al, 2007), "Roseomonas chloroacetimidivorans" (Chu et al, 2016), and "Candidatus Roseomonas massiliae" (Greub et al, 2004) are not valid names. "Roseomonas hellenica" was described recently (Rat et al, 2021).…”

The genus Roseomonas is a significant group of bacteria which is invariably of great clinical and ecological importance. Previous studies have shown that the genus Roseomonas is polyphyletic in nature. Our present study focused on generating a lucid understanding of the phylogenetic framework for the re-evaluation and reclassification of the genus Roseomonas. Phylogenetic studies based on the 16S rRNA gene and 92 concatenated genes suggested that the genus is heterogeneous, forming seven major groups. Existing Roseomonas species were subjected to an array of genomic, phenotypic, and chemotaxonomic analyses in order to resolve the heterogeneity. Genomic similarity indices (dDDH and ANI) indicated that the members were well-defined at the species level. The Percentage of Conserved Proteins (POCP) and the average Amino Acid Identity (AAI) values between the groups of the genus Roseomonas and other interspersing members of the family Acetobacteraceae were below 65 and 70%, respectively. The pan-genome evaluation depicted that the pan-genome was an open type and the members shared 958 core genes. This claim of reclassification was equally supported by the phenotypic and chemotaxonomic differences between the groups. Thus, in this study, we propose to re-evaluate and reclassify the genus Roseomonas and propose six novel genera as Pararoseomonas gen. nov., Falsiroseomonas gen. nov., Paeniroseomonas gen. nov., Plastoroseomonas gen. nov., Neoroseomonas gen. nov., and Pseudoroseomonas gen. nov.

“…At the time of writing, 18 species and two subspecies names were validly published in the genus Roseomonas . Although the species names ‘ Roseomonas aceris ’ (Tonouchi & Tazawa, 2014) and ‘ Roseomonas musae ’ (Nutaratat et al , 2013) were effectively published, these have not been validly published. Phylogenetically, the genus Roseomonas (Rihs et al , 1993) is classified under the family Acetobacteraceae of the order Rhodospirillales in the class Alphaproteobacteria .…”

A non-motile, coccus-shaped, pale-pink-pigmented bacterium, designated strain JC288 T , was isolated from a paddy rhizosphere soil collected from Western Ghats, Kankumbi, Karnataka, India. Cells were found to be Gram-stain-negative, and catalase-and oxidase-positive; the major fatty acids were C 16 : 0 , C 16 : 1 v7c/C 16 : 1 v6c, C 18 : 1 v7c/C 18 : 1 v6c and C 18 : 1 2-OH. The predominant respiratory quinone was Q-10 and the genomic DNA G+C content was 67.5 mol%. Strain JC288T contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, four unidentified aminolipids, three unidentified phospholipids, two unidentified lipids, an aminophospholipid and a glycolipid. Hydroxyspirilloxanthin was the major carotenoid of strain JC288 T . 16S rRNA gene sequence comparisons indicated that strain JC288 T represents a member of the genus Roseomonas within the family Acetobacteraceae of the phylum Proteobacteria. Strain JC288 T shared the highest 16S rRNA gene sequence similarity with Roseomonas rhizosphaerae YW11 T (97.3 %),Roseomonas aestuarii JC17 T (97.1 %), Roseomonas cervicalis CIP 104027 T (95.9 %) and other members of the genus Roseomonas (,95.5 %). The distinct genomic difference and morphological, physiological and chemotaxonomic differences from the previously described taxa support the classification of strain JC288 T as a representative of a novel species of the genus Roseomonas, for which the name Roseomonas oryzae sp. nov. is proposed. The type strain is JC288 T (5KCTC 42542 T 5LMG 28711 T ).

An aerobic, Gram-stain-negative, coccobacillus-shaped, non-endospore-forming, pink-pigmented bacterium, designated PN2 T , was isolated from an olive leaf. The strain grew at 15-35 8C with an optimum temperature for growth at 30 8C, and at pH 5.0-7.5 with an optimum pH for growth at 6.0. Growth was observed in the presence of up to 1.02 % (w/v) NaCl. The major fatty acids were C 19 : 0 cyclo v8c, C 16 : 0 and C 18 : 1 v7c. The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, phosphatidylglycerol, unknown aminolipids, an unknown phospholipid and an unknown lipid. The respiratory quinone was ubiquinone-10. The DNA G+C content of strain PN2 T was 70.4 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain PN2 T was closely related to members of the genus Roseomonas and shared highest similarity with Roseomonas mucosa ATCC BAA-692 T (96.5 %), Roseomonas gilardii subsp. gilardii ATCC 49956 T (96.2 %) and Roseomonas gilardii subsp. rosea ATCC BAA-691 T (96.2 %). Furthermore, the DNA-DNA relatedness value between strain PN2 T and the closest related species R. mucosa ATCC BAA-692 T was 27 %. These data allowed the phenotypic and genotypic differentiation of strain PN2 T from its closest phylogenetic neighbour (R. mucosa ATCC BAA-692 T ). Based on phenotypic and genotypic characteristics, strain PN2 T is classified as representing a novel species of the genus Roseomonas for which the name Roseomonas elaeocarpi sp. nov. is proposed. The type strain is PN2 T (5BCC 44864 T 5NBRC 107871 T ).Bacteria of the genus Roseomonas were first described by Rihs et al. (1993). They are Gram-stain-negative with plump coccus, coccobacillus or short rod shapes. Based on 16S rRNA gene sequence analysis, this genus belongs to the Alphaproteobacteria (Weyant & Whitney, 2005). At the time of writing, 23 species and two subspecies with validly published names are members of the genus Roseomonas, recently recognized species including Roseomonas aerophila (Kim et al., 2013) There have been reports on the isolation of Roseomonas species from various sources such as medical and environmental samples including plant phyllosphere. Together, these findings indicate that members of the genus Roseomonas exist widely in nature. Rihs et al. (1993) reported that the DNA G+C content of the genus Roseomonas ranges from 65 to 71 mol%. However, Kim et al. (2013) showed the DNA G+C content of R. aerophila was 73.0 mol%, slightly above values previously reported, and Dong et al. (2014) reported a 63.0 mol% DNA G+C content for R. alkaliterrae, a value that was slightly below values for species in the genus Roseomonas. From a literature review, the highest content for aThe GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain PN2 T is AB594202. major fatty acid of this genus was for C 18 : 1 v7c under the conditions studied (Gallego et al., 2006;Yoon et al., 2007;Furuhata et al., 2008Furuhata et al., , 2013Yoo et al., 2008;Zhang et al., 2008; Venkata Ramana et al., 2010;Lo...
