Incubation of <i>Nannochloropsis</i> spp. in the dark for one week led to significant increases in the cellular concentrations of LCAs and LCDs in both species. Consistently, 13C-labeled substrate experiments confirmed that both LCA and LCD were actively produced in the dark from C14–18 fatty acids by either condensation or elongation/hydroxylation, although no enzymatic evidence was found for the former pathway. <i>Nannochloropsis</i> spp. did, however, contain (1) multiple polyketide synthases (PKSs) including one type (PKS Clade II) that might catalyse incomplete fatty acid elongations leading to the formation of 3-OH-fatty acids, (2) 3-hydroxyacyl dehydratases (HADs), which can possibly form Δ2/Δ3 monounsaturated fatty acids, and (3) fatty acid elongases (FAEs) that could elongate 3-OH-fatty acids and Δ2/Δ3 monounsaturated fatty acids to longer products. The enzymes responsible for reduction of the long chain fatty acids to LCDs and LCAs are, however, unclear. A putative wax ester synthase/acyl coenzyme A (acyl-CoA):diacylglycerol acyltransferase (WS-DGAT) is likely to be involved in the esterification of LCAs and LCDs in the cell wall. Our data thus provide useful insights in predicting the biosynthetic pathways of LCAs and LCDs in phytoplankton suggesting a key role of FAE and PKS enzymes.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Biosynthesis of long chain alkyl diols and long chain alkenols in <i>Nannochloropsis</i> spp. (Eustigmatophyceae)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-10 01:32:22.415009","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2019,"MonPub":null,"DateUpdate":"2023-05-17","DateCreate":"2019-05-13","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000486634000005","VABBcode":null,"OpenAcc":1,"DOI":"10.1093/pcp/pcz078"},"refs":null,"anarec":{"AnaID":310966,"PubliDate":2019,"Pagination":"1666-1682","XtraPublOfAnaID":null,"ISBN":null,"Volume":"60","Issue":"8","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43678,"SerRR":"Plant and cell physiology.
