Here, we cloned and identified two homologous BMP receptor genes, <i>PfBMPR1B</i> and <i>PfBAMBI</i>, from the pearl oyster <i>Pinctada fucata</i>. Real-time quantitative PCR and <i>in situ</i> hybridization revealed that these genes were expressed in mantle edge and pallial, specifically located at the outer epithelia. Knockdown of <i>PfBMPR1B</i> by RNA interference (RNAi) significantly decreased the expression levels of matrix protein (MP) genes and induced the abnormal ultrastructure of prismatic and nacreous layers. Conversely, knockdown of <i>PfBAMBI</i> significantly increased the expression levels of a portion of MP genes and induced the overgrowth of nacreous layer crystals. In the RNAi and shell notching experiments, MP gene expressions were competitively regulated by <i>PfBMPR1B</i> and <i>PfBAMBI</i>. In addition, the receptor inhibitor LDN193189 reduced the expression levels of MP genes in mantle primary cells and larvae, and induced abnormal D-shaped shell formation during larval development. Collectively, these results clearly show that <i>PfBMPR1B</i> and <i>PfBAMBI</i> are involved in regulating shell biomineralization in <i>P</i>. <i>fucata</i>. Our study therefore provides the direct evidence that BMP receptors participate in mollusc biomineralization.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"The receptor genes <i>PfBMPR1B</i> and <i>PfBAMBI</i> are involved in regulating shell biomineralization in the pearl oyster <i>Pinctada fucata</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-06 01:33:41.298980","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2017,"MonPub":null,"DateUpdate":"2018-02-13","DateCreate":"2017-09-19","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000408429900001","VABBcode":null,"OpenAcc":1,"DOI":"10.1038/s41598-017-10011-y"},"refs":null,"anarec":{"AnaID":289399,"PubliDate":2017,"Pagination":"15 pp","XtraPublOfAnaID":null,"ISBN":null,"Volume":"7","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":208093,"SerRR":"Scientific Reports (Nature Publishing Group).
