Potato scab caused by pathogenic Streptomyces is a serious soil-borne disease on potato. In this study, a new Streptomyces strain 5A-1 was isolated from potato samples in China. Based on morphological characteristics, 16S rDNA gene sequence analyses, it was identified as Streptomyces griseoplanus (Streptacidiphilus griseoplanus), pathogenicity of which was measured by the methods of small potato chips, radish slices and potato pot trial inoculation. Moreover, the pathogenic genes txtAB and tomA from the Streptomyces pathogenicity island (PAI) were detected. Determination of biological characteristics showed that the optimal temperature for the growth of S. griseoplanus strain 5A-1 was 25 °C, the optimal light condition was darkness, the optimal pH value was 8.5 and the most preferred carbon source and nitrogen source is glucose and aspartate, respectively. To our knowledge, it is the first report for S. griseoplanus, as a new pathogen, to cause potato scab.
