title: Nonomuraea fuscirosea sp. nov., an actinomycete isolated from the rhizosphere soil of rehmannia (Rehmannia glutinosa Libosch).
abstract: A novel actinomycete, designated strain NEAU-dht8(T), was isolated from the rhizosphere soil of rehmannia (Rehmannia glutinosa Libosch) and characterized using a polyphasic approach. The organism was found to have morphological and chemotaxonomic characteristics typical of the genus Nonomuraea. The G+C content of the DNA was 68.47 mol%. On the basis of 16S rRNA gene sequence similarity studies, strain NEAU-dht8(T) was most closely related to Nonomuraea maheshkhaliensis 16-5-14(T) (99.31%), Nonomuraea kuesteri GW 14-1925(T) (98.77%), Nonomuraea coxensis JCM 13931(T) (98.71%), Nonomuraea wenchangensis 210417(T) (98.44 %), Nonomuraea bangladeshensis 5-10-10(T) (98.36%) and Nonomuraea salmonea DSM 43678(T) (98.0%); similarities to other species of the genus Nonomuraea were lower than 98%. Two tree-making algorithms based on 16S rRNA gene sequences showed that the isolate formed a phyletic line with its closest neighbour N. maheshkhaliensis 16-5-14(T). However, the low level of DNA-DNA relatedness allowed the novel isolate to be differentiated from N. maheshkhaliensis 16-5-14(T). Strain NEAU-dht8(T) could also be differentiated from other species of the genus Nonomuraea showing high 16S rRNA gene sequence similarity (98-98.77%) by morphological and physiological characteristics. Thus, strain NEAU-dht8(T) is considered to represent a novel species of the genus Nonomuraea, for which the name Nonomuraea fuscirosea sp. nov. is proposed. The type strain is NEAU-dht8(T) ( = CGMCC 4.7104(T) = DSM 45880(T)).
