The strain formed well-developed substrate mycelium, but no aerial mycelium. It grew at 10–45 °C, at pH 5–10 (optimum pH 7) and in the presence of 0–3 % (w/v) NaCl. The DNA G+C content was 73.0 mol%. Phylogenetic analyses showed that strain YIM 68255T belonged to the genus Plantactinospora . However, it exhibited some differences from Plantactinospora mayteni YIM 61359T and the level of DNA–DNA relatedness was 42.7±1.3 %. Based on comparative analysis of physiological and chemotaxonomic data, it is proposed that strain YIM 68255T represents a novel species of the genus Plantactinospora , Plantactinospora endophytica sp. nov., with strain YIM 68255T ( = DSM 45387T = CCTCC AA 209047T) as the type strain. In addition, it is also proposed that Actinaurispora siamensis Thawai et al. 2010 be transferred to the genus Plantactinospora as Plantactinospora siamensis comb. nov. [type strain CM2-8T ( = JCM 15677T = BCC 34762T)] based on chemotaxonomic characteristics and phylogenetic analysis. Emended descriptions of the genus Plantactinospora and Plantactinospora mayteni are also provided.", }
