“…In Japanese flounder, Tdrd7a showed gonad-enriched expression among adult tissues and was also germ cell specifically distributed in embryo and gonads. Conversely, Tdrd7b was not expressed with the similar tissue and cell specificity (Wang et al 2019b), which suggested that the duplicated Tdrd7a and Tdrd7b in Japanese flounder may have undergone functional divergence. Similarly, in spotted sea bass and Asian sea bass, Tdrd7a was more highly expressed in testis than in ovaries, whereas Tdrd7b was not highly expressed in gonads but with moderate expression in brain (Fig.…”

“…In addition, 13 Tdrd genes were recognized in tongue sole (CsTdrd). Thirteen Tdrd members from Japanese flounder (PoTdrd) were retrieved from Wang et al (2019b). Together with other represented vertebrate species (teleosts, birds, amphibians and mammals, Supplementary Table S1), the copy number of Tdrd genes was identified.…”

“…Tudor domain-containing (TDRD) proteins, namely, with multiple repeated Tudor domains, are members of a highly conserved protein family which are abundantly expressed in germline cells and involved in germ cell development. The Tdrd family is widely recognized across diverse organisms, with 13 members including Tdrd1, Tdrkh (Tdrd2), Tdrd3, Rnf17 (Tdrd4), Tdrd5, Tdrd6, Tdrd7, Stk31 (Tdrd8), Tdrd9, Tdrd10, Snd1 (Tdrd11), Ecat8 (Tdrd12), and Tdrd15 (Chen et al 2017;Wang et al 2019b). The Tdrd family genes have functions associated with many fundamental biological processes, including histone modification, RNA metabolism, as well as the response of DNA damage (Chen et al 2011;Lasko 2010;Pek et al 2012;Siomi et al 2010;Thomson and Lasko 2005).…”

“…However, as the key components participating in the piRNA pathway, studies about the evolutionary dynamics and function of Tdrd genes in teleosts, especially in nonmodel fish, are limited with only a few reports in zebrafish (Danio rerio) (Huang 2012), swamp eel (M. albus) (Chen et al 2017), and Japanese flounder (P. olivaceus) (Wang et al 2019b). Therefore, first, we characterized the Tdrd family members in teleost species with diverse sexual development patterns, including spotted sea bass (Lateolabrax maculatus) and Asian sea bass (Lates calcarifer).…”

Tudor domain-containing (TDRD) proteins, the germline enriched protein family, play essential roles in the process of gametogenesis and genome stability through their interaction with the PIWI-interacting RNA (piRNA) pathway. Several studies have suggested the rapid evolution of the piRNA pathway in teleost lineages with striking reproductive diversity. However, there is still limited information about the function and evolution of Tdrd genes in teleost species. In this study, through genome wide screening, 13 Tdrd family genes were identified in economically important aquaculture fish, including spotted sea bass (Lateolabrax maculatus), Asian sea bass (Lates calcarifer), and tongue sole (Cynoglossus semilaevis). With copy number, structure, phylogeny, and synteny analysis, duplication of Tdrd6 and Tdrd7, as well as loss of Stk31 and Tdrd10, were characterized in teleost lineages. Codon based molecular evolution analysis indicated faster evolution of teleost Tdrd genes than that in mammals, potentially associated with the accelerated evolution of the piRNA pathway in teleost lineages. The evolutionary diversity of Tdrd genes was also detected between different teleost lineages. RNA-seq analysis showed that most teleost Tdrd genes were dominantly expressed in gonads, particularly highly expressed in testis, such as Tdrd6, Tdrd7a, Tdrd9, Ecat8, and Tdrd15. The varied expression and evolutionary pattern between the duplicated Tdrd6 and Tdrd7 in teleosts may indicate their functional diversification. All these results suggest a conserved function of teleost Tdrd family in gametogenesis and the piRNA pathway, which could lay a foundation for the evolution of Tdrd genes and be helpful for further deciphering of Tdrd functions in teleosts.

“…For example, the expansion of NLR family suggest that NLRs have a more substantial role in the innate immunity in haddock [48]. The expansion of tdrd family may be related to their important function in germline in Japanese flounder [49]. Members of Myo2 subfamily have been identified to play an important role in muscle development in teleost but in different regulatory ways.…”

Myosins are important eukaryotic motor proteins that bind actin and utilize the energy of ATP hydrolysis to perform a broad range of functions such as muscle contraction, cell migration, cytokinesis, and intracellular trafficking. However, the characterization and function of myosin is poorly studied in teleost fish. In this study, we identified 60 myosin family genes in a marine teleost, black rockfish (Sebastes schlegelii), and further characterized their expression patterns. myosin showed divergent expression patterns in adult tissues, indicating they are involved in different types and compositions of muscle fibers. Among 12 subfamilies, S. schlegelii myo2 subfamily was significantly expanded, which was driven by tandem duplication events. The up-regulation of five representative genes of myo2 in the skeletal muscle during fast-growth stages of juvenile and adult S. schlegelii revealed their active role in skeletal muscle fiber synthesis. Moreover, the expression regulation of myosin during the process of myoblast differentiation in vitro suggested that they contribute to skeletal muscle growth by involvement of both myoblast proliferation and differentiation. Taken together, our work characterized myosin genes systemically and demonstrated their diverse functions in a marine teleost species. This lays foundation for the further studies of muscle growth regulation and molecular mechanisms of indeterminate skeletal muscle growth of large teleost fishes.
