In this study, two recombinant influenza A viruses with a neuraminidase (NA) segment harboring enhanced green fluorescent protein (EGFP) in the background of A\/PR\/8\/34 (PR8) were generated. The viral RNA (vRNA)-specific packaging signals for NA were largely retained for efficient packaging. An \u201cautocleave\u201d 2A peptide sequence, which was inserted at the N terminus or the COOH terminus of NA to link with EGFP, enabled NA and EGFP to be expressed monocistronically. Further analysis demonstrated that both viruses, named rPR8-EGFP+NA and rPR8-NA+EGPF, although with some characteristic differences in growth and EGFP expression, could replicate in noncomplementary cells and propagate to large quantities while maintaining genome stability after multiple passages in embryonated eggs. These replication-competent influenza viruses carrying reporter genes are a great addition to the tool set for developing antiviral therapeutics and vaccines and for\n            <jats:italic>in vivo<\/jats:italic>\n            studies of viral dissemination and pathogenicity.\n          <\/jats:p>","DOI":"10.1128\/jvi.00046-10","type":"journal-article","created":{"date-parts":[[2010,9,9]],"date-time":"2010-09-09T02:05:40Z","timestamp":1283997940000},"page":"12075-12081","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":37,"title":["Generation of Replication-Competent Recombinant Influenza A Viruses Carrying a Reporter Gene Harbored in the Neuraminidase Segment"],"prefix":"10.1128","volume":"84","author":[{"given":"Feng","family":"Li","sequence":"first","affiliation":[{"name":"State Key Laboratory of Respiratory Diseases, Guangzhou Institute of Biomedicine and Health (GIBH), Chinese Academy of Sciences, Guangzhou 510530"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liqiang","family":"Feng","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Respiratory Diseases, Guangzhou Institute of Biomedicine and Health (GIBH), Chinese Academy of Sciences, Guangzhou 510530"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weiqi","family":"Pan","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Respiratory Diseases, Guangzhou Institute of Biomedicine and Health (GIBH), Chinese Academy of Sciences, Guangzhou 510530"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenyuan","family":"Dong","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Respiratory Diseases, Guangzhou Institute of Biomedicine and Health (GIBH), Chinese Academy of Sciences, Guangzhou 510530"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chufang","family":"Li","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Respiratory Diseases, Guangzhou Institute of Biomedicine and Health (GIBH), Chinese Academy of Sciences, Guangzhou 510530"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caijun","family":"Sun","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Respiratory Diseases, Guangzhou Institute of Biomedicine and Health (GIBH), Chinese Academy of Sciences, Guangzhou 510530"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ling","family":"Chen","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Respiratory Diseases, Guangzhou Institute of Biomedicine and Health (GIBH), Chinese Academy of Sciences, Guangzhou 510530"},{"name":"Department of Medical Biotechnology, University of Science &amp;
