Picophytoplankton, such as <i>Micromonas polaris</i>, are predicted to benefit from such changes. However, little is known about how these environmental changes affect the viruses that exert a strong mortality pressure on these small but omnipresent algae. Here we report on one-step infection experiments, combined with measurements of host physiology and viability, with 2 strains of <i>M. polaris</i> and the virus MpoV-45T under 3 light intensities (5, 60 and 160 μmol quanta m<sup>−2</sup> s<sup>−1</sup>), 2 light period regimes (16:8 and 24:0 h light:dark cycle) and 2 temperatures (3 and 7 °C). Our results show that low light intensity (16:8 h light:dark) delayed the decline in photosynthetic efficiency and cell lysis, while decreasing burst size by 46%. In contrast, continuous light (24:0 h light:dark) shortened the latent period by 5 h for all light intensities, and even increased the maximum virus production rate and burst size under low light (by 157 and 69%, respectively). Higher temperature (7 °C vs 3 °C) led to earlier cell lysis and increased burst size (by 19%), except for the low light conditions. These findings demonstrate the ecological importance of light in combination with temperature as a controlling factor for Arctic phytoplankton host and virus dynamics seasonally, even more so in the light of global warming.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Influence of irradiance and temperature on the virus MpoV-45T infecting the Arctic picophytoplankter <i>micromonas polaris</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Arctic algal viruses; Light intensity; Light regime; Global Climate Change; Virus growth characteristics","OtherDescriptors":null,"Notes":null,"AnaPub":2018,"MonPub":null,"DateUpdate":"2019-07-05","DateCreate":"2019-01-23","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000455313100015","VABBcode":null,"OpenAcc":1,"DOI":"10.3390/v10120676"},"refs":null,"anarec":{"AnaID":304879,"PubliDate":2018,"Pagination":"676","XtraPublOfAnaID":null,"ISBN":null,"Volume":"10","Issue":"12","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":243760,"SerRR":"Viruses.
