Pathogen-induced changes in enzyme activities are correlated with shifts in microbial community composition, but causal relationships remain unclear. This study investigates the effects of five key pathogens\u2014<jats:italic>Phytophthora infestans<\/jats:italic>, <jats:italic>Streptomyces scabies<\/jats:italic>, <jats:italic>Spongospora subterranea<\/jats:italic>, <jats:italic>Ralstonia solanacearum<\/jats:italic> and <jats:italic>Globodera rostochiensis<\/jats:italic>\u2014on soil enzyme activities and microbial community structure in potato rhizosphere soils under continuous cropping. This experiment involved pathogen inoculation and soil sampling in potato rhizosphere soils, with treatments replicated three times. Potatoes were planted on March 22, 2023, and harvested on August 25, 2023. Enzymatic activities were measured at different growth stages, and microbial communities were analyzed using high-throughput sequencing. Pathogen-induced variations in enzymatic activities were observed, potentially promoting disease proliferation. For instance, under <jats:italic>S. scabies<\/jats:italic> stress, urease (URE) activity increased significantly at the full flowering and post-flowering stages, while catalase (CAT) activity decreased significantly during the seedling and full flowering stages. Under <jats:italic>S. subterranea<\/jats:italic> stress, activities of urease, sucrase (SUC), and alkaline phosphatase (ALP) decreased. <jats:italic>M. nematode<\/jats:italic> stress led to a decline in URE and sucrase activities. <jats:italic>P. infestans<\/jats:italic> infection led to a decrease in URE activity at the sowing stage. Furthermore, microbial community composition was significantly correlated with disease incidence, with specific taxa such as <jats:italic>Planctomycetes<\/jats:italic> and <jats:italic>Basidiomycota<\/jats:italic> showing negative correlations with <jats:italic>S. subterranea<\/jats:italic> incidence, while <jats:italic>Candidatus Dormibacteraeota<\/jats:italic> and <jats:italic>Ascomycota<\/jats:italic> were positively associated with <jats:italic>P. infestans<\/jats:italic>. These results suggest that pathogen-induced changes in enzymatic activities play a critical role in disease dynamics and microbial interactions. The findings highlight the importance of understanding the effects of soilborne pathogens on soil enzyme activities and microbial communities, providing insights into disease management strategies in potato farming.<\/jats:p>","DOI":"10.3389\/fpls.2025.1564704","type":"journal-article","created":{"date-parts":[[2025,4,28]],"date-time":"2025-04-28T05:31:19Z","timestamp":1745818279000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Impact of plant pathogens on potato rhizosphere enzymes and microbial dynamics"],"prefix":"10.3389","volume":"16","author":[{"given":"Gaihuan","family":"Xu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Linmei","family":"Deng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jian","family":"Dao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenping","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chunjiang","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanli","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xia","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,4,28]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"1017","DOI":"10.1080\/15226514.2017.1319326","article-title":"Rhizospheric soil enzyme activities and phytominimg potential of Aeluropus lagopoides and Cyperus conglomeratus growing in contaminated soils at the banks of artificial lake of reclaimed wastewate","volume":"19","author":"Abbas","year":"2017","journal-title":"Int.
