BACKGROUND DNA barcoding aims to provide an efficient method for species-level identifications using an array of species specific molecular tags derived from the 5' region of the mitochondrial cytochrome c oxidase I (COI) gene. The efficiency of the method hinges on the degree of sequence divergence among species and species-level identifications are(More)
BACKGROUND DNA barcoding is one means of establishing a rapid, accurate, and cost-effective system for the identification of species. It involves the use of short, standard gene targets to create sequence profiles of known species against sequences of unknowns that can be matched and subsequently identified. The Fish Barcode of Life (FISH-BOL) campaign has(More)
The population genetic structure of the crimson snapper Lutjanus erythropterus in East Asia was examined with a 427-bp hypervariable portion of the mtDNA control region. A total of 262 samples were collected and 75 haplotypes were obtained. Neutrality tests (Tajima's and Fu's) suggested that Lutjanus erythropterus in East Asia had experienced a bottleneck(More)
Aeromonas hydrophila, a widespread bacterium in the aquatic environment, causes haemorrhagic septicemia in fish. In the last decade, the disease has caused mass mortality and tremendous economic loss in cultured grass carp in the mainland China. The complement component C6 is a constituent of a biochemical cascade that serves as a major effector of the(More)
BACKGROUND DNA barcoding has been advanced as a promising tool to aid species identification and discovery through the use of short, standardized gene targets. Despite extensive taxonomic studies, for a variety of reasons the identification of fishes can be problematic, even for experts. DNA barcoding is proving to be a useful tool in this context. However,(More)

DNA barcoding is a molecular method that uses a short standardized DNA sequence as a species identification tool. In this study, the standard 652 base-pair region of the mitochondrial cytochrome oxidase subunit I gene (COI) was sequenced in marine fish specimens captured in China. The average genetic distance was 50-fold higher between species than within(More)
The spotted scat, Scatophagus argus, has become a popular commercial fish in recent years. However, spotted scat fingerlings originate mainly from wild resources due to difficulties in the artificial propagation of this species. Thus, an understanding of its population genetic structure is necessary for its conservation management and commerical(More)
Excessive inflammation resulting from activation of the innate immune system significantly contributes to ischemia/reperfusion injury (IRI). Inflammatory reactions in both IRI and infections share the same signaling pathways evoked by danger/pathogen associated molecular pattern molecules. The cytosolic retinoid-inducible gene I(RIG-I)-like RNA receptor(More)
Normally siRNA has to be chemically stabilized in therapeutic applications. It is a challenge to obtain optimal stabilizing effects while maintaining full silencing activity due to a lack of understanding of how different chemical modifications would influence the efficacy of siRNA. In the current study, the effect of single 2'-sugar modifications was(More)
By interacting with Na(+), K(+)-ATPase (NKA), the FXYD domain-containing ion transport regulator (FXYD) is involved in teleost osmoregulation, but knowledge of FXYD in marine fish is limited. In the present study, fxyd11 and fxyd12 were identified from the spotted scat (Scatophagus argus), and the two members of the FXYD protein family were expressed in a(More)
