(2025) obtain 959 whole genome sequences of H1N1 subtype swine influenza virus (SIV) isolated from China. Their analysis of the sequences, isolated between 1977 and 2020, reveals how H1N1 lineages have co-evolved and contributed to instances of zoonotic transmission within the region. This study\u2019s findings characterize the long-term evolutionary effects of frequent viral reassortment in SIV and highlight its potential to drive future pandemics.<\/jats:p>","DOI":"10.1093\/evolut\/qpaf262","type":"journal-article","created":{"date-parts":[[2025,12,20]],"date-time":"2025-12-20T12:47:45Z","timestamp":1766234865000},"page":"510-511","source":"Crossref","is-referenced-by-count":0,"title":["Digest: Reassortment-based evolution of H1N1 subtype swine influenza virus in China"],"prefix":"10.1093","volume":"80","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-8325-1146","authenticated-orcid":false,"given":"Ares","family":"Casas","sequence":"first","affiliation":[{"name":"San Jos\u00e9 State University Department of Biological Sciences, , San Jos\u00e9 ,","place":["United States"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2025,12,22]]},"reference":[{"issue":"9","key":"2026021802170308700_bib1","doi-asserted-by":"publisher","first-page":"2314","DOI":"10.1099\/vir.0.021402-0","article-title":"Viral reassortment and transmission after co-infection of pigs with classical H1N1 and triple-reassortant H3N2 swine influenza viruses","volume":"91","author":"Ma","year":"2010","journal-title":"Journal of General Virology"},{"key":"2026021802170308700_bib2","doi-asserted-by":"publisher","first-page":"233","DOI":"10.1016\/b978-0-12-800964-2.00017-3","article-title":"Viral evolution: It is all about mutations","volume-title":"Viral pathogenesis: From basics to systems biology","author":"Stern","year":"2016","edition":"Third edition"},{"issue":"8","key":"2026021802170308700_bib3","doi-asserted-by":"publisher","first-page":"e01930","DOI":"10.1128\/jvi.01930-19","article-title":"A single amino acid at position 431 of the PB2 protein determines the virulence of H1N1 swine influenza viruses in mice","volume":"94","author":"Xu","year":"2020","journal-title":"Journal of Virology"},{"issue":"(1)","key":"2026021802170308700_bib4","doi-asserted-by":"publisher","first-page":"168","DOI":"10.1093\/evolut\/qpaf213","article-title":"Genetic diversity and evolution of H1N1 subtype swine influenza virus in China: A comprehensive analysis from 1977 to 2020","volume":"80","author":"Zhao","year":"2026","journal-title":"Evolution; International Journal of Organic Evolution"}],"container-title":["Evolution"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/academic.oup.com\/evolut\/advance-article-pdf\/doi\/10.1093\/evolut\/qpaf262\/66098189\/qpaf262.pdf","content-type":"application\/pdf","content-version":"am","intended-application":"syndication"},{"URL":"https:\/\/academic.oup.com\/evolut\/article-pdf\/80\/2\/510\/66098189\/qpaf262.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/academic.oup.com\/evolut\/article-pdf\/80\/2\/510\/66098189\/qpaf262.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,2,18]],"date-time":"2026-02-18T07:17:10Z","timestamp":1771399030000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/evolut\/article\/80\/2\/510\/8400336"}},"subtitle":[],"editor":[{"given":"Kati","family":"Moore","sequence":"additional","affiliation":[],"role":[{"role":"editor","vocabulary":"crossref"}]},{"given":"Jason","family":"Wolf","sequence":"additional","affiliation":[],"role":[{"role":"editor","vocabulary":"crossref"}]}],"short-title":[],"issued":{"date-parts":[[2025,12,22]]},"references-count":4,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2025,12,22]]},"published-print":{"date-parts":[[2026,2,18]]}},"URL":"https:\/\/doi.org\/10.1093\/evolut\/qpaf262","relation":{},"ISSN":["0014-3820","1558-5646"],"issn-type":[{"value":"0014-3820","type":"print"},{"value":"1558-5646","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[2026,2]]},"published":{"date-parts":[[2025,12,22]]}}}
