Phytohabitans flavus sp. nov., Phytohabitans rumicis sp. nov. and Phytohabitans houttuyneae sp. nov., isolated from plant roots, and emended description of the genus Phytohabitans.
An actinomycete strain, designated K09-0627(T), was isolated from the roots of an orchid collected in Okinawa Prefecture, Japan. Two actinomycete strains K11-0047(T) and K11-0057(T) were isolated from the roots of Rumex acetosa and Houttuynia cordata collected in Kanagawa Prefecture, Japan. 16S rRNA gene sequence analyses indicated that the isolates belonged to the genus Phytohabitans, and that they were closely related to each other and to Phytohabitans suffuscus K07-0523(T). The DNA-DNA relatedness values between the three isolates and Phytohabitans suffuscus were below 70%. On the basis of phylogenetic analysis, DNA-DNA relatedness values and phenotypic characteristics, the strains should be classified as novel species in the genus Phytohabitans, for which the names Phytohabitans flavus sp. nov. (type strain, K09-0627(T)=JCM 17387(T)=NBRC 107702(T)=DSM 45551(T)), Phytohabitans rumicis sp. nov. (type strain, K11-0047(T)=JCM 17829(T)=NBRC 108638(T)=BCC 48146(T)) and Phytohabitans houttuyneae sp. nov. (type strain, K11-0057(T)=JCM 17830(T)=NBRC 108639(T)=BCC 48147(T)) are proposed.
