In this study, the testis tissue transcriptome was used to identify candidate genes and key pathways associated with fecundity in sheep. Histological analysis of testis tissue using hematoxylin\u2013eosin (HE) routine staining was performed for two sheep breeds. Overall, 466 differentially expressed genes (DEGs) were identified between Hu sheep (HS) and Tibetan sheep (TS) through RNA sequencing technology (RNA-Seq), including 226 upregulated and 240 downregulated genes. Functional analysis showed that several terms and pathways, such as \u201cprotein digestion and absorption\u201d, \u201ccAMP signaling pathway\u201d, \u201cfocal adhesion\u201d, and \u201cp53 signaling pathway\u201d were closely related to testis development and spermatogenesis. Several genes (including COL1A1, COL1A2, COL3A1, SOX9, BCL2, HDC, and GGT5) were significantly enriched in these terms and pathways and might affect the reproduction of sheep by regulating the migration of spermatogenic cells, apoptosis of spermatogenic cells, and secretion of sterol hormones via testicular interstitial cells. Our results provide a theoretical basis for better understanding the molecular mechanisms of reproduction in sheep.<\/jats:p>","DOI":"10.3390\/genes13122212","type":"journal-article","created":{"date-parts":[[2022,11,28]],"date-time":"2022-11-28T04:01:33Z","timestamp":1669608093000},"page":"2212","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Transcriptomic Study of Spermatogenesis in the Testis of Hu Sheep and Tibetan Sheep"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1991-393X","authenticated-orcid":false,"given":"Xiaoyu","family":"Fu","sequence":"first","affiliation":[{"name":"College of Animal Science and Technology, Gansu Agricultural University, Lanzhou 730070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanan","family":"Yang","sequence":"additional","affiliation":[{"name":"College of Animal Science and Technology, Gansu Agricultural University, Lanzhou 730070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8701-0647","authenticated-orcid":false,"given":"Zunqiang","family":"Yan","sequence":"additional","affiliation":[{"name":"College of Animal Science and Technology, Gansu Agricultural University, Lanzhou 730070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miaomiao","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Animal Science and Technology, Gansu Agricultural University, Lanzhou 730070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinrong","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Animal Science and Technology, Gansu Agricultural University, Lanzhou 730070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,25]]},"reference":[{"key":"ref_1","first-page":"810","article-title":"Seasonal reproductive patterns of early domestic sheep at Tell Halula (PPNB, Middle Euphrates Valley): Evidence from sequential oxygen isotope analyses of tooth enamel","volume":"6","author":"Tornero","year":"2016","journal-title":"J.
