A species-specific method for detecting pathogenic Streptomyces species from soil and potato tubers in Argentina.

Potato common scab is caused by several soil-inhabiting pathogenic Streptomyces species. In the present study, a species-specific PCR method was used to detect Streptomyces species in potato tuber lesions and soils. Total genomic DNA from soil samples from six locations and tuber samples from four potato cultivars (Spunta, Shepody, Innovator and Russet Burbank) were assessed.
