Recently, 2‐alkyl‐4‐quinolones have been isolated from marine bacteria, both of which (the bacterium and isolated chemical) inhibited growth of microalgae, suggesting these compounds could mediate diatom–bacteria interactions. The effects of several quinolones on three diatom species have been investigated. The growth of all three was inhibited, with half‐maximal inhibitory concentrations reaching the sub‐micromolar range. By using multiple techniques, dual inhibition mechanisms were uncovered for 2‐heptyl‐4‐quinolone (HHQ) in <i>Phaeodactylum tricornutum</i>. Firstly, photosynthetic electron transport was obstructed, primarily through inhibition of the cytochrome <i>b</i><sub>6</sub><i>f</i> complex. Secondly, respiration was inhibited, leading to repression of ATP supply to plastids from mitochondria through organelle energy coupling. These data clearly show how HHQ could modulate diatom proliferation in marine environments.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"The multifaceted inhibitory effects of an alkylquinolone on the diatom <i>Phaeodactylum tricornutum</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":"cytochromes; diatom-bacteria interactions; photosynthesis; quinolones;reaction mechanisms","OtherDescriptors":null,"Notes":null,"AnaPub":2020,"MonPub":null,"DateUpdate":"2021-04-07","DateCreate":"2020-04-07","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000509613800001","VABBcode":null,"OpenAcc":1,"DOI":"10.1002/cbic.201900612"},"refs":null,"anarec":{"AnaID":322759,"PubliDate":2020,"Pagination":"1206-1216","XtraPublOfAnaID":null,"ISBN":null,"Volume":"21","Issue":"8","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":215798,"SerRR":"ChemBioChem.
