However, few roles of lncRNA in the reproductive process of the Pacific oyster (Crassostrea gigas) have been defined, especially in the regulatory mechanism of sterile triploids gametogenesis. To uncover the potential role of lncRNA, the gonads of diploids, sterile triploids, and partially sterile triploids underwent RNA sequencing. A total of 9618 reliable lncRNAs were identified. The target relationship between lncRNA and mRNA was predicted based on cis, trans, and antisense regulation with bioinformatic software. We chose differentially expressed lncRNAs and mRNAs when sterile triploids were compared to partially sterile triploids and diploids for subsequent functional enrichment analysis. Findings revealed that trans-regulatory lncRNAs might play a significant role in the gametogenesis of C. gigas. Combining pathway results, we constructed core networks of lncRNAs\u2013mRNAs for triploid sterile females and hermaphrodites. Fifty-four genes related to cell division, germline-cell maintenance, and glycogen metabolism were found to be associated with sterility. A total of 28 candidate lncRNAs were predicted to trans-regulate these genes. We speculated that MSTRG.79882.3 and MSTRG.79882.4 for triploid sterile females and MSTRG.33704.1, MSTRG.63844.1, and MSTRG.5675.1 for hermaphrodites were highly important as they were predicted to regulate more sterility-specific genes than others. Our work collectively identified sterility-related lncRNAs and implicated the potential mechanism of lncRNA-mediated regulation in the gametogenesis of sterile triploid oysters.<\/jats:p>","DOI":"10.3390\/biology11030378","type":"journal-article","created":{"date-parts":[[2022,2,27]],"date-time":"2022-02-27T20:46:17Z","timestamp":1645994777000},"page":"378","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Transcription Analysis for Core Networks of lncRNAs\u2013mRNAs: Implication for Potential Role in Sterility of Crassostrea gigas"],"prefix":"10.3390","volume":"11","author":[{"given":"Huihui","family":"Wang","sequence":"first","affiliation":[{"name":"Key Laboratory of Mariculture (Ministry of Education), Ocean University of China, Qingdao 266003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hong","family":"Yu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Mariculture (Ministry of Education), Ocean University of China, Qingdao 266003, China"},{"name":"Laboratory for Marine Fisheries Science and Food Production Processes, Pilot National Laboratory for Marine Science and Technology (Qingdao), Qingdao 266237, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qi","family":"Li","sequence":"additional","affiliation":[{"name":"Key Laboratory of Mariculture (Ministry of Education), Ocean University of China, Qingdao 266003, China"},{"name":"Laboratory for Marine Fisheries Science and Food Production Processes, Pilot National Laboratory for Marine Science and Technology (Qingdao), Qingdao 266237, China"},{"name":"Laboratory of Tropical Marine Germplasm Resources and Breeding Engineering, Sanya Oceanographic Institution, Ocean University of China, Sanya 572000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5777-489X","authenticated-orcid":false,"given":"Shikai","family":"Liu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Mariculture (Ministry of Education), Ocean University of China, Qingdao 266003, China"},{"name":"Laboratory for Marine Fisheries Science and Food Production Processes, Pilot National Laboratory for Marine Science and Technology (Qingdao), Qingdao 266237, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,2,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3533","DOI":"10.1016\/j.ygeno.2021.08.018","article-title":"Comprehensive analysis of miRNA-mRNA\/lncRNA during gonadal development of triploid female rainbow trout (Oncorhynchus mykiss)","volume":"113","author":"Huang","year":"2021","journal-title":"Genomics"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"239","DOI":"10.1016\/j.tig.2015.03.007","article-title":"The Landscape of long noncoding RNA classification","volume":"31","author":"Wahlestedt","year":"2015","journal-title":"Trends Genet."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"393","DOI":"10.1016\/j.cell.2018.01.011","article-title":"Functional Classification and Experimental Dissection of Long Noncoding RNAs","volume":"172","author":"Kopp","year":"2018","journal-title":"Cell"},{"key":"ref_4","doi-asserted-by":"crossref","first-page":"251","DOI":"10.1016\/j.omtn.2021.05.006","article-title":"SMAD4-induced knockdown of the antisense long noncoding RNA BRE-AS contributes to granulosa cell apoptosis","volume":"25","author":"Yao","year":"2021","journal-title":"Mol.
