To resolve this disagreement, we quantified carbon isotope fractionation by a wild-type planktic β-cyanobacterium (<em>Synechococcus</em> sp. PCC 7002), an engineered Proterozoic analog lacking a CO<sub>2</sub>-concentrating mechanism, and cyanobacterial mats. At mid-Proterozoic pH and <em>p</em>CO<sub>2</sub> values, carbon isotope fractionation by the wild-type β-cyanobacterium is fully consistent with the Proterozoic carbon isotope record, suggesting that cyanobacteria with CO<sub>2</sub>-concentrating mechanisms were apparently the major primary producers in the pelagic Proterozoic ocean, despite atmospheric CO<sub>2</sub> levels up to 100 times modern. The selectively permeable microcompartments central to cyanobacterial CO<sub>2</sub>-concentrating mechanisms (“carboxysomes”) likely emerged to shield rubisco from O<sub>2</sub> during the Great Oxidation Event.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Carbon isotope evidence for the global physiology of Proterozoic cyanobacteria","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":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2021-02-11","DateCreate":"2021-02-11","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000606331400015","VABBcode":null,"OpenAcc":1,"DOI":"10.1126/sciadv.abc8998"},"refs":null,"anarec":{"AnaID":333863,"PubliDate":2021,"Pagination":"eabc8998","XtraPublOfAnaID":null,"ISBN":null,"Volume":"7","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":248966,"SerRR":"Science Advances.
