Abstract
As an invasive alien animal, Pomacea canaliculata poses a great danger to the ecology and human beings. Recently, there has been a gradual shift towards bio-friendly control. Based on the development of RNA interference and CRISPR technology as molecular regulatory techniques for pest control, it was determined if the knockout of genes related to sex differentiation in P. canaliculata could induce sterility, thereby helping in population control. However, the knowledge of sex differentiation- and development-related genes in P. canaliculata is currently lacking. Here, transcriptomic approaches were used to study the genes expressed in the two genders of P. canaliculata at various developmental stages. Gonad transcriptomes of immature or mature males and females were compared, revealing 12,063 genes with sex-specific expression, of which 6066 were male- and 5997 were female-specific. Among the latter, 581 and 235 genes were up-regulated in immature and mature females, respectively. The sex-specific expressed genes identified included GnRHR2 and TSSK3 in males and ZAR1 and WNT4 in females. Of the genes, six were involved in reproduction: CCNBLIP1, MND1, DMC1, DLC1, MRE11, and E(sev)2B. Compared to immature snail gonads, the expression of HSP90 and CDK1 was markedly reduced in gonadal. It was hypothesized that the two were associated with the development of females. These findings provided new insights into crucial genetic information on sex differentiation and development in P. canaliculata. Additionally, some candidate genes were explored, which can contribute to future studies on controlling P. canaliculata using molecular regulatory techniques.

Identification and characterization of a new germline-specific marker vasa gene and its promoter in the giant freshwater prawn Macrobrachium rosenbergii. Comp Biochem Physiol B Biochem Mol Biol 2022; 259:110716. [PMID: 34999221 DOI: 10.1016/j.cbpb.2022.110716] [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: 11/26/2021] [Revised: 12/27/2021] [Accepted: 01/04/2022] [Indexed: 11/21/2022]
Abstract
Vasa gene encodes a protein member of DEAD-box superfamily of ATP-dependent RNA helicases, which plays a key role in germline development in metazoans. In present study, we identified a new germline-specific marker Mrvasa in the prawn Macrobrachium rosenbergii, whose genomic DNA sequence consists of 14 exons and 13 introns. A 2516 bp of full-length Mrvasa cDNA encodes a protein of 603 amino acids. It contains nine conserved motifs, a zinc-finger motif, and RGG repeats. RT-PCR indicated that Mrvasa mRNA was specifically expressed in gonads. QPCR analysis further revealed that the expression of Mrvasa mRNA is much higher in testis than in ovary. In testis, the relative expression level of Mrvasa mRNA in late developing stage is significantly higher than that in early-middle developing stage. During ovarian development, no significant difference in expression was found. In situ hybridization demonstrated that Mrvasa mRNA was localized in germline cells including spermatogonia, spermatocytes, and spermatozoa in testes, and previtellogenic and vitellogenic oocytes in ovary. We then isolated the Mrvasa promoter and determined the transcription core region of this promoter. This is the first report on identification of vasa core promoter in crustaceans. Our results will provide a useful germline-specific marker Mrvasa for tracing germline cell formation and development in M. rosenbergii.

FISH & SHELLFISH IMMUNOLOGY 2015; 47:1067-1074. [PMID: 26314522 DOI: 10.1016/j.fsi.2015.08.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/30/2015] [Revised: 08/17/2015] [Accepted: 08/20/2015] [Indexed: 06/04/2023]
Abstract
Oncoprotein NM23, as a family of genes encoding the nucleoside diphosphate (NDP) kinase, plays important roles in bioenergetics, DNA replication, differentiation and tumor metastasis. In this study, a full-length cDNA of NM23 (designated EcNM23) was cloned from Exopalaemon carinicauda by using rapid amplification of cDNA ends (RACE) approaches. The full-length cDNA of EcNM23 was 755 bp, which contains an open reading frame (ORF) of 518 bp, encoding a 175 amino-acid polypeptide with the predicted molecular weight of 19.60 kDa and estimated isoelectric point of 7.67. The deduced amino acid sequence of EcNM23 shared high identity (86%-93%) with that of other crustaceans. a NDP kinase super family signature was identified in E. carinicauda EcNM23. Quantitative real-time RT-qPCR analysis indicated that EcNM23 was expressed in all the examined tissues with the high expression level in hemocytes and ovary. The EcNM23 expression in immune-related tissues changed rapidly and reached peak at different time after pathogens (Vibrio parahaemolyticus and WSSV) challenge and ammonia-N stress treatment. The results suggested that EcNM23 might be associated with the immune defenses to pathogens infection and ammonia-N stress in E. carinicauda.
