It is assumed that GFP is acting as a “neutral” protein with no influence on the bacterial physiology. To verify this hypothesis, the virulence of <i>Vibrio splendidus</i> ME9, <i>Vibrio anguillarum</i> NB10, and their respective GFP-tagged strains ME9-GFP and NB10-GFP (transconjugants) was compared in vitro and tested in vivo towards blue mussel (<i>Mytilus edulis</i>) larvae<i>.</i> Results showed that the incorporation of GFP negatively impacted the growth and swimming motility of NB10 in vitro. Correspondingly, the mRNA levels of genes involved in bacterial swimming motility (<i>flaA</i>, <i>flaE</i>, and <i>cheR</i>) were significantly down-regulated in NB10-GFP. As for the strain ME9 on the other hand, GFP incorporation only had a negative effect on swimming motility. However, both the strains NB10-GFP and ME9-GFP showed almost the same virulence as their respective parental strain towards mussel larvae in vivo. Overall, the data presented here demonstrated that incorporation of GFP may cause modifications in cell physiology and highlight the importance of preliminary physiological tests to minimize the negative influence of GFP tagging when it is used to monitor the target localization. The study also supports the idea that the virulence of <i>Vibrio</i> species is determined by complex regulatory networks. Notwithstanding the change of a single physiological trait, especially growth or swimming motility, the GFP-tagged <i>Vibrio</i> strain can thus still be considered usable in studies mainly focusing on the virulence of the strain.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Can only one physiological trait determinate the adverse effect of green fluorescent protein (GFP) incorporation on <i>Vibrio</i> virulence?","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-19 01:32:16.345917","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Green fluorescent protein (GFP); Vibrio; Swimming motility; Flagellin genes; Virulence; Mytilus edulis larvae","OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2022-06-29","DateCreate":"2022-06-28","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000698885800004","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/s00253-021-11556-9"},"refs":null,"anarec":{"AnaID":353178,"PubliDate":2021,"Pagination":"7899-7912","XtraPublOfAnaID":null,"ISBN":null,"Volume":"105","Issue":"20","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42367,"SerRR":"Applied Microbiology and Biotechnology.
