Complete Genome Sequence of a Betanodavirus Isolated from Half-Smooth Tongue Sole (Cynoglossus semilaevis)

چکیده
Betanodavirus, commonly called nervous necrosis virus (NNV) of fish, has emerged as a major constraint on marine aquaculture worldwide. Here, we report the complete genome sequence of a betanodavirus (strain CsCN128) isolated from diseased half-smooth tongue sole (Cynoglossus semilaevis) in China. The genome sequence of strain CsCN128 shares ≥98.7% similarity with seven-band grouper nervous necrosis virus from Japan. Phylogenetic analysis indicates that strain CsCN128 belongs to the red-spotted grouper nervous necrosis virus (RGNNV) genotype of betanodavirus. The genome of the strain CsCN128 will facilitate further study on the molecular epidemiology and natural susceptible host range of betanodaviruses.

Construction of a microsatellite-based genetic linkage map for half-smooth tongue sole Cynoglossus semilaevis
The half-smooth tongue sole Cynoglossus semilaevis is an important cultured marine fish and a promising model fish for the study of sex determination. Sex-specific genetic linkage maps of half-smooth tongue sole were developed with 567 markers (565 microsatellite markers and two SCAR markers). The parents and F1 progeny (92 individuals) were used as segregating populations. The female map was c...
متن کاملMolecular Method for Sex Identification of Half-Smooth Tongue Sole (Cynoglossus semilaevis) Using a Novel Sex-Linked Microsatellite Marker
Half-smooth tongue sole (Cynoglossus semilaevis) is one of the most important flatfish species for aquaculture in China. To produce a monosex population, we attempted to develop a marker-assisted sex control technique in this sexually size dimorphic fish. In this study, we identified a co-dominant sex-linked marker (i.e., CyseSLM) by screening genomic microsatellites and further developed a nov...
متن کاملSingle Locus Maintains Large Variation of Sex Reversal in Half-Smooth Tongue Sole (Cynoglossus semilaevis)
Sex determination is a fundamental biological process for individual sex development and population sex ratios. However, for some species, the primary sex might be altered during development, and individuals can develop into the opposite sex. Sex reversal may happen in insects, reptiles, amphibians, and fishes. In half-smooth tongue sole (Cynoglossus semilaevis), some genetically female fish ir...
متن کاملMolecular cloning and expression analysis of the aqp1aa gene in half-smooth tongue sole (Cynoglossus semilaevis)
Aquaporin 1 (AQP1) is a member of the transmembrane water channel family of proteins with special structural features, and two AQP1 paralogous genes (aqp1aa and aqp1ab) are reported in teleosts. In the present study, the aqp1aa gene of half-smooth tongue sole (Cynoglossus semilaevis) was cloned and characterized. The full-length cDNA of aqp1aa is 1411 bp with a 786 bp open reading frame encodin...
متن کاملEstablishment and Characterization of a Testicular Cell Line from the Half-Smooth Tongue Sole, Cynoglossus semilaevis
Spermatogenesis within the adult testis is an excellent system for studying stem cell renewal and differentiation, which is under the control of testicular somatic cells. In order to understanding spermatogenesis in the half-smooth tongue sole (Cynoglossus semilaevis) as a marine fish model of aquaculture importance, we established a cell line called CSGC from a juvenile gonad of this organism....
