    Abstract:
    A Gram-negative, aerobic, yellow-pigmented, non-spore-forming, motile, rod-shaped bacterium, designated strain Gsoil 3046(T), was isolated from soil from a ginseng field in Pocheon Province, South Korea, and was characterized taxonomically by using a polyphasic approach. A comparative analysis of 16S rRNA gene sequences revealed that strain Gsoil 3046(T) belongs to the family Xanthomonadaceae in the Gammaproteobacteria. The greatest sequence similarity was found with respect to Dyella koreensis KCTC 12359(T) (97.7 %), Dyella japonica IAM 15069(T) (97.4 %), Frateuria aurantia DSM 6220(T) (96.7 %), Fulvimonas soli LMG 19981(T) (96.2 %) and Luteibacter rhizovicinus DSM 16549(T) (96.0 %). The phylogenetic distances from other recognized species within the family Xanthomonadaceae, including Dyella yeojuensis KACC 11405(T), were greater than 4.0 % (i.e. the sequence similarities were less than 96.0 %). DNA-DNA hybridization experiments showed that the levels of DNA-DNA relatedness between strain Gsoil 3046(T) and its phylogenetically closest neighbours were below 25 %. The G+C content of the genomic DNA was 66.6 mol%. In addition, the presence of ubiquinone Q-8 as the predominant respiratory quinone, iso-C(17 : 1)omega9c, iso-C(16 : 0), iso-C(15 : 0) and iso-C(17 : 0) as the major cellular fatty acids and iso-C(13 : 0) 3-OH and iso-C(11 : 0) 3-OH as the major hydroxy fatty acids supported the affiliation of strain Gsoil 3046(T) to the genus Dyella. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain Gsoil 3046(T) represents a novel species in the genus Dyella, for which the name Dyella ginsengisoli sp. nov. is proposed. The type strain is Gsoil 3046(T) (=KCTC 12599(T)=DSM 18387(T)).
