Interpretive Summary: Common scab disease of potato occurs in all potato-growing regions of the world with severe economic impact. Common scab is known to be caused by fourteen distinct species of Streptomyces bacteria. An additional lineage of plant pathogenic Streptomyces is proposed here as the novel species Streptomyces griseoscabiei. Because different potato cultivars respond differentially to distinct species of Streptomyces, it is critical to characterize the diversity of phytopathogenic Streptomyces. Identification and formal description of novel species of Streptomyces enables more accurate classification Streptomyces to aid growers in understanding and managing control of local pathogen populations.

Technical Abstract: Streptomyces strain NRRL B-2795 is described as the type strain of Streptomyces griseoscabiei sp. nov. based on whole-genome average nucleotide identity. This strain was previously named as S. scabiei but suggested as a potential novel species. A second Streptomyces strain, NRRL B-16521, previously named as S. scabiei and also previously suggested as a potential novel species, is assigned to S. acidiscabies based on whole-genome average nucleotide identity. Morphological and biochemical characterizations also support these designations. Both Streptomyces sp. strain NRRL B-2795 and NRRL B-16521 cause common scab on multiple cultivars of potato.
