Abstract
Shells and pearls are the products of biomineralization of shellfish after ingesting external mineral ions. Bone morphogenetic proteins (BMPs) play a role in a variety of biological function, and the genes that encode them, are considered important shell-forming genes in mollusks and are associated with shell and pearl formation, embryonic development, and other functions, but bone morphogenetic protein 10 (BMP10) is poorly understood in Hyriopsis cumingii. In this study, we cloned Hc-BMP10 and obtained a 2477 bp full-length sequence encoding 460 amino acids with a conserved TGF-β structural domain. During the embryonic developmental stages, the cleavage stage had the highest expression of Hc-BMP10, followed by juvenile clams; the expression in the mantle gradually decreased with increasing mussel age. A strong signal was detected on epidermal cells on the mantle edge by in situ hybridization. In both the shell notching and inserting operations of the pearl fragment assay, we found that the expression of Hc-BMP10 increased after the above treatments. RNA interference assays showed that the silencing of Hc-BMP10 resulted in a change in the morphology of the prismatic layer and nacreous layer, with the prismatic layer less closely aligned and the disordered aragonite flakes in the nacreous layer. These findings indicate that Hc-BMP10 is involved in the growth and development of H. cumingii, as well as the formation of shells and pearls. Therefore, this study provides some reference for selecting superior species for growth and pearl breeding of H. cumingii at a molecular level and further investigation of the molecular mechanism for biomineralization of Hc-BMP10.

Transcription factor CgPOU3F4-like regulates expression of pheomelanin synthesis related gene CgB-aat1 in the Pacific oyster (Crassostrea gigas). Gene 2023; 861:147258. [PMID: 36754175 DOI: 10.1016/j.gene.2023.147258] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2022] [Revised: 01/24/2023] [Accepted: 02/03/2023] [Indexed: 02/08/2023]
Abstract
Previous study has found that b (0, +) -type amino acid transporter 1 (CgB-aat1) plays an essential role on mantle pigmentation in the Pacific oyster Crassostrea gigas. However, the molecular regulation of CgB-aat1 gene expression remains unclear. Herein, three POU domain family members, CgPOU2F1, CgPOU3F4-like and CgPOU4F3-X1 were characterized and they all had POUs and HOX domains, respectively, which were important in transcriptional regulation. CgPOU3F4-like gene expression was the highest in mantle edge. Subsequently, the dual-luciferase reporter result showed that the core regulatory region of CgB-aat1 gene was from -632 to -350 bp of promoter. In transient co-transfection assays, the strongest activity was activated only by CgPOU3F4-like, suggesting CgPOU3F4-like was a valid transcriptional activator of CgB-aat1 gene promoter. And the structural integrity of CgPOU3F4-like was essential for its activation function. In addition, site directed mutagenesis assay was applied to detect three key binding sites between CgPOU3F4-like and core region of CgB-aat1 gene promoter, and this interaction was verified by ChIP test. Furthermore, CgPOU3F4-like knockdown by RNA interference led to obvious decreases in CgB-aat1 and cystathionine beta-synthase (CgCbs) expressions at both mRNA and protein levels. Collectively, these results indicate that CgPOU3F4-like positively regulate CgB-aat1 gene expression and it may be a critical upstream transcriptional regulation factor in pheomelanin synthesis in C. gigas.

Sun D, Yu H, Li Q. Early gonadal differentiation is associated with the antagonistic action of Foxl2 and Dmrt1l in the Pacific oyster. Comp Biochem Physiol B Biochem Mol Biol 2023; 265:110831. [PMID: 36681266 DOI: 10.1016/j.cbpb.2023.110831] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2022] [Revised: 01/14/2023] [Accepted: 01/14/2023] [Indexed: 01/19/2023]
Abstract
As the second largest phylum in the zoological kingdom next to arthropods, the mechanism of gonadal differentiation in mollusca is quite complex. Currently, although much has been carried out on gonadal differentiation in the Pacific oyster, there is still unknown information that needs to be further explored. Here, analysis of the Foxl2 and Dmrt1l expression in samples at different development periods of male and female gonads as well as in annual gonad samples revealed that Log10 (Foxl2/Dmrt1l) values were an effective method for sex identification in oysters. In differentiated gonadal tissue, Log10 (Foxl2/Dmrt1l) values greater than 2 were females and less than 1 for males. Subsequent sequential sampling of the same individuals verified that Log10 (Foxl2/Dmrt1l) values greater than 2 for resting gonads would develop as females and less than 1 would develop as males in the future. Relative expression analysis of Foxl2 and Dmrt1l in the annual samples revealed a negative correlation between Log10 (Foxl2) and Log10 (Dmrt1l). Double fluorescence reporter validation results showed that DMRT1L protein was able to bind the Foxl2 promoter and repress its activity with a weak dosage effect. Antagonism between Dmrt1l and Foxl2 is therefore not restricted to vertebrates, and the competing regulatory networks are of great significance in the maintenance of gonadal sex in oysters after sexual differentiation. This study provides novel ideas and insights into the study of early gonadal differentiation in the adult oyster.

Candidate pigmentation genes related to feather color variation in an indigenous chicken breed revealed by whole genome data. Front Genet 2022; 13:985228. [PMID: 36479242 PMCID: PMC9720402 DOI: 10.3389/fgene.2022.985228] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2022] [Accepted: 10/10/2022] [Indexed: 08/27/2023] Open
Abstract
Chicken plumage color is an inheritable phenotype that was naturally and artificially selected for during domestication. The Baicheng You chicken is an indigenous Chinese chicken breed presenting three main feather colors, lavender, black, and yellow plumages. To explore the genetic mechanisms underlying the pigmentation in Baicheng You chickens, we re-sequenced the whole genome of Baicheng You chicken with the three plumage colors. By analyzing the divergent regions of the genome among the chickens with different feather colors, we identified some candidate genomic regions associated with the feather colors in Baicheng You chickens. We found that EGR1, MLPH, RAB17, SOX5, and GRM5 genes were the potential genes for black, lavender, and yellow feathers. MLPH, GRM5, and SOX5 genes have been found to be related to plumage colors in birds. Our results showed that EGR1 is a most plausible candidate gene for black plumage, RAB17, MLPH, and SOX5 for lavender plumage, and GRM5 for yellow plumage in Baicheng You chicken.
