| Abstract: | Acid scab of potatoes occurs frequently in strongly acidic soils at pH 3.9–5.2. On the basis of the phylogenetic relationships derived from 16S rDNA sequences and physiological characteristics, we identified the organism causing this disease in potatoes grown in the Uwaba district of Saga Prefecture, Kyushu Island, southwest Japan, as Streptomyces acidiscabies. Another pathogen that occurred more frequently in weakly acidic to neutral soils, rather than strongly acidic soils, was identified as S. scabiei. Streptomyces acidiscabies tended to produce superficial lesions, while S. scabiei mostly produced raised and/or erumpent lesions. |
