However, conventional plasmid construction using <jats:italic>Escherichia coli<\/jats:italic> (<jats:italic>E.coli<\/jats:italic>) cloning is time\u2010consuming and has difficulties handling DNA encoding genes toxic for <jats:italic>E.coli<\/jats:italic> or highly repeated sequences. These limitations hamper rapid virus synthesis. In this study, we establish a very rapid in vitro one-pot plasmid construction (IVOC) based virus synthesis. This method dramatically reduced the time for genome plasmid construction, which was used for virus synthesis, from several days or more to about 8 hours. Moreover, infectious viruses could be synthesized with a similar yield to the conventional <jats:italic>E.coli<\/jats:italic> cloning-based method with high accuracy. The applicability of this method was also demonstrated by the generation of recombinant viruses carrying reporter genes from the IVOC products. This method enables the pathogenicity analysis and vaccine development using genetically modified viruses, and it is expected to allow for faster analysis of newly emerging variants than ever before. Furthermore, its application to other RNA viruses is also expected.<\/jats:p>","DOI":"10.1371\/journal.pone.0312776","type":"journal-article","created":{"date-parts":[[2024,11,8]],"date-time":"2024-11-08T18:28:39Z","timestamp":1731090519000},"page":"e0312776","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":1,"title":["In
