As the algae are hosted inside the symbiosome, all metabolic exchanges must take place across the symbiosome membrane. Using functional studies in <i>Xenopus</i> oocytes, immunolocalization, and confocal Airyscan microscopy, we established that <i>Acropora yongei</i> Rh (ayRhp1) facilitates transmembrane NH<sub>3</sub> and CO<sub>2</sub> diffusion and that it is present in the symbiosome membrane. Furthermore, ayRhp1 abundance in the symbiosome membrane was highest around midday and lowest around midnight. We conclude that ayRhp1 mediates a symbiosomal NH<sub>4</sub><sup>+</sup>-trapping mechanism that promotes nitrogen delivery to algae during the day—necessary to sustain photosynthesis—and restricts nitrogen delivery at night—to keep algae under nitrogen limitation. The role of ayRhp1-facilitated CO<sub>2</sub> diffusion is less clear, but it may have implications for metabolic dysregulation between symbiotic partners and bleaching. This previously unknown mechanism expands our understanding of symbioses at the immediate animal-microbe interface, the symbiosome.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"A Rhesus channel in the coral symbiosome membrane suggests a novel mechanism to regulate NH<sub>3</sub> and CO<sub>2</sub> delivery to algal symbionts","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":2022,"MonPub":null,"DateUpdate":"2022-03-17","DateCreate":"2022-03-17","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000800003800011","VABBcode":null,"OpenAcc":1,"DOI":"10.1126/sciadv.abm0303"},"refs":null,"anarec":{"AnaID":350466,"PubliDate":2022,"Pagination":"eabm0303","XtraPublOfAnaID":null,"ISBN":null,"Volume":"8","Issue":"10","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":248966,"SerRR":"Science Advances.
