Many microalgae harbor characteristic satellite bacteria, many of which participate in <i>N</i>-acyl homoserine lactone (AHL) mediated quorum sensing. In the diffusion-controlled phycosphere, AHLs can reach high local concentrations, with some of them transforming into tetramic acids, compounds with a broad bioactivity. We tested a representative AHL, <i>N</i>-(3-oxododecanoyl) homoserine lactone, and its tetramic acid rearrangement product on the diatom <i>Phaeodactylum tricornutum</i>. While cell growth and photosynthetic efficiency of photosystem II were barely affected by the AHL, exposure to its tetramic acid rearrangement product had a negative effect on photosynthetic efficiency and led to growth inhibition and cell death in the long term, with a minimum inhibitory concentration between 20 and 50 μΜ. These results strengthen the view that AHLs may play an important role in shaping the outcome of microalgae–bacteria interactions.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"<i>N</i>-acyl homoserine lactone derived tetramic acids impair photosynthesis in <i>Phaeodactylum tricornutum</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:01.897972","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2019,"MonPub":null,"DateUpdate":"2019-07-25","DateCreate":"2019-05-28","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000459367200008","VABBcode":null,"OpenAcc":0,"DOI":"10.1021/acschembio.8b01101"},"refs":null,"anarec":{"AnaID":311421,"PubliDate":2019,"Pagination":"198-203","XtraPublOfAnaID":null,"ISBN":null,"Volume":"14","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":262385,"SerRR":"ACS Chemical Biology.
