A Gram-stain-positive, non-motile and coccus-shaped bacterium, designated strain LNNU 331112T, was isolated from the composite rhizosphere soil of the halophyteSuaeda aralocaspica(Bunge) Freitag and Schütze, which was collected in Xinjiang, north-west China. Growth occurred at 10–45 °C, pH 6.0–11.0 and in the presence of 0–10 % NaCl (w/v). Phylogenetic analysis based on the 16S rRNA gene sequence suggested that strain LNNU 331112Tbelonged to the genusHoyosellaand showed 95.6, 95.5 and 95.4 % sequence similarities toHoyosella altamirensisDSM 45258T,Hoyosella subflavaCGMCC 4.3532TandHoyosella rhizosphaeraeCGMCC 1.15478T, respectively. The estimated digital DNA–DNA hybridization relatedness values between strain LNNU 331112Tand the type strains ofH. altamirensisDSM 45258T,H. subflavaCGMCC 4.3532TandH. rhizosphaeraeCGMCC 1.15478Twere 18.9, 19.3 and 18.3 %, respectively. The average nucleotide identity values between strain LNNU 331112TandH. altamirensisDSM 45258T,H. subflavaCGMCC 4.3532TandH. rhizosphaeraeCGMCC 1.15478Twere 72.6, 72.7 and 72.3 %, respectively. The genome sequence of strain LNNU 331112Tshowed 69.0–72.3 % average amino acid identity values in comparison with the related genome sequences of three validly publishedHoyosellaspecies. The genome of strain LNNU 331112Twas 3.47 Mb, with a DNA G+C content of 68.4 mol%. A total of 3182 genes were identified as protein-coding in strain LNNU 331112T. Genomic analysis revealed that a number of genes involved in osmotic pressure regulation, intracellular pH homeostasis and potassium (K+) uptake protein were found in strain LNNU 331112T. The predominant menaquinones were MK-8 (44.6 %) and MK-7 (55.4 %), which differentiated strain LNNU 331112Tfrom other three recognizedHoyosellaspecies. Major fatty acids (>10 %) were C17 : 1 ω8c(33.8 %), C16 : 0(23.3 %), C17 : 0(12.8 %) and summed feature 3 (12.9 %), which also clearly separated strain LNNU 331112Tfrom three recognizedHoyosellaspecies. The polar lipid profile of strain LNNU 331112Tincluded diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol, one unidentified glycolipid, one unidentified phospholipid and two unidentified lipids. According to the results of phenotypic, chemotaxonomic and phylogenetic analyses, strain LNNU 331112Tis considered to represent a novel species of the genusHoyosella, for which the nameHoyosella suaedaesp. nov. is proposed. The type strain is LNNU 331112T(=KCTC 39808T=CGMCC 1.17107T=DSM 103463T).
