Comparison of genetic difference in cultured Pampus populations between China and Kuwait based on COI partial sequences
In order to investigate genetic variance and genetic diversity between China and Kuwait cultured populations of silver pomfret, COI partial sequences were compared and analyzed. By PCR amplification and sequencing, 47 sequences were obtained, and 8 haplotyes were defined. The polymorphic sites in China and Kuwait populations were 4 and 14, respectively. The contents of A+T are higher than G+C in each populations, and both populations showed higher levels of haplotype diversity(0.566~0.643) and lower levels of nucleotide diversity(0.0022~0.0030). Results of NJ phylogenetic tree and genetic distance suggest that cultured pampus in two countries have significant genetic variance, and should be viewed as two different species.
