Tsuneonella

Abstract

Abstract Tsu.ne.o.nel'la. N.L. fem. dim. n. Tsuneonella , named in honor of Tsuneo Shiba who established genus Erythrobacter . Pseudomonadota / Alphaproteobacteria / Sphingomonadales / Erythrobacteraceae / Tsuneonella The members of the genus Tsuneonella have been isolated from various environments, including air, freshwater, sediment, and sea urchin. Cells are ovoid to rod‐shaped, non‐spore‐forming, Gram‐stain‐negative, and nonmotile. They are aerobic or facultatively aerobic and contain carotenoid pigments but not bacteriochlorophyll a . The predominant quinone is ubiquinone‐10, and the major fatty acid is C 18:1 ω7 c or summed feature 8 (C 18:1 ω7 c and/or C 18:1 ω6 c ). The major polar lipids include diphosphatidylglycerol (DPG) and phosphatidylethanolamine (PE). Based on phylogenic analysis of the core genome, the genus Tsuneonella represents a distinct lineage in the family Erythrobacteraceae of the class Alphaproteobacteria . DNA G + C content (mol%) : 60.5–67.0 (genome sequence). Type species : Tsuneonella dongtanensis Xu et al. 2020 VP (basonym: Altererythrobacter dongtanensis Fan et al. 2011 VP ).
