Different species of pathogens may affect disease control strategies due to their biological characteristics. To determine pathogen composition in the major potato production area, northern China, potato tubers with various types of PCS symptoms were collected from 18 counties. From 57 collected samples, 159 bacterial isolates of\n Streptomyces<\/jats:italic>\n spp. were obtained on oatmeal agar. Pathogenicity of these isolates was examined on tuber disks and potted plants of potato, resulting in 42 isolates being confirmed as pathogenic and causing typical scabby symptoms. To confirm pathogenicity determinants, the\n txtAB<\/jats:italic>\n ,\n tomA<\/jats:italic>\n , and\n nec1<\/jats:italic>\n genes of these pathogens were detected using polymerase chain reaction (PCR). Pathogenic isolates were also identified by the combination of morphological, physiological, and biochemical characteristics, BOX-PCR,\n 16S<\/jats:italic>\n rDNA, and multilocus sequence analysis. Among the 42 pathogenic\n Streptomyces<\/jats:italic>\n isolates, 36 (85.7% of total isolates) were identified as\n Streptomyces galilaeus<\/jats:italic>\n , and 6 (14.3%) as\n Streptomyces scabies<\/jats:italic>\n . The genome of\n S. galilaeu<\/jats:italic>\n s isolates from the predominant group was resequenced, yielding six distinct genetic clusters. The Shangdu population exhibited the most complex genetic structure. The dominance and genetic diversity of\n S. galilaeus<\/jats:italic>\n revealed in this study provide a critical foundation for breeding resistant potato varieties and developing targeted control measures tailored to the agroecological conditions of northern China.\n <\/jats:p>\n \n IMPORTANCE<\/jats:title>\n \n Potato common scab (PCS) caused by pathogenic\n Streptomyces<\/jats:italic>\n seriously affects the quality and economic value of potato, especially in northern China. The species of\n Streptomyces<\/jats:italic>\n were closely related to their geographical distribution. We determined that\n Streptomyces galilaeus<\/jats:italic>\n is dominant in this area, rather than\n Streptomyces scabies<\/jats:italic>\n , which is widely distributed. This finding emphasizes the importance of developing effective prevention and control strategies for the region. In addition, genome resequencing of\n S. galilaeus<\/jats:italic>\n revealed significant genetic diversity, with the Shangdu population displaying the most complex structure. These results provide important information for further understanding the population structure and distribution of PCS pathogens.\n <\/jats:p>\n <\/jats:sec>\n <\/jats:sec>","DOI":"10.1128\/spectrum.03050-25","type":"journal-article","created":{"date-parts":[[2026,3,19]],"date-time":"2026-03-19T13:00:29Z","timestamp":1773925229000},"update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":0,"title":["Genetic diversity of\n Streptomyces<\/i>\n species causing potato common scab in northern China"],"prefix":"10.1128","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0696-2388","authenticated-orcid":true,"given":"Yuchen","family":"Li","sequence":"first","affiliation":[{"name":"Key Laboratory of Biopesticide Creation and Resource Utilization in Inner Mongolia Autonomous Region, College of Horticulture and Plant Protection, Inner Mongolia Agricultural University","place":["Hohhot, China"]},{"name":"State Key Laboratory of Agricultural and Forestry Biosecurity, MARA Key Lab of Surveillance and Management for Plant Quarantine Pests, College of Plant Protection, China Agricultural University","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chi","family":"Li","sequence":"additional","affiliation":[{"name":"Guangdong Provincial Key Laboratory of Biotechnology for Plant Development, School of Life Sciences, South China Normal University","place":["Guangzhou, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianjun","family":"Hao","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01adr0w49","id-type":"ROR","asserted-by":"publisher"}],"name":"School of Food and Agriculture, University of Maine","place":["Orono, USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianping","family":"Zhang","sequence":"additional","affiliation":[{"name":"Institute of Plant Protection, Inner Mongolia Academy of Agriculture and Animal Husbandry Sciences","place":["Hohhot, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liwei","family":"Wang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Biopesticide Creation and Resource Utilization in Inner Mongolia Autonomous Region, College of Horticulture and Plant Protection, Inner Mongolia Agricultural University","place":["Hohhot, China"]},{"name":"State Key Laboratory of Agricultural and Forestry Biosecurity, MARA Key Lab of Surveillance and Management for Plant Quarantine Pests, College of Plant Protection, China Agricultural University","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qi","family":"Wang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Agricultural and Forestry Biosecurity, MARA Key Lab of Surveillance and Management for Plant Quarantine Pests, College of Plant Protection, China Agricultural University","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pingping","family":"Sun","sequence":"additional","affiliation":[{"name":"Key Laboratory of Biopesticide Creation and Resource Utilization in Inner Mongolia Autonomous Region, College of Horticulture and Plant Protection, Inner Mongolia Agricultural University","place":["Hohhot, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3814-4187","authenticated-orcid":false,"given":"Wenbing","family":"Zhang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Biopesticide Creation and Resource Utilization in Inner Mongolia Autonomous Region, College of Horticulture and Plant Protection, Inner Mongolia Agricultural University","place":["Hohhot, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2240-4319","authenticated-orcid":false,"given":"Xiaoyu","family":"Zhang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Biopesticide Creation and Resource Utilization in Inner Mongolia Autonomous Region, College of Horticulture and Plant Protection, Inner Mongolia Agricultural University","place":["Hohhot, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1094\/PDIS.1997.81.8.901"},{"key":"e_1_3_4_3_2","first-page":"56","article-title":"Occurrence and control approach of potato common scab (Streptomyces spp.) in Inner Mongolia","volume":"27","author":"Zhang JP","year":"2013","unstructured":"Zhang JP, Yin YH, Yan RP, Ha S, Lin TR, Cheng YC, Hu B. 2013.
