Partial fragments of the 16 S rRNA gene of puffer fish from 13 species belonging to 3 genus collected from Fujian province and 9 samples from unknown species were amplified by polymerase chain reaction(PCR) using the universal 16 S rRNA gene primers. The PCR products were sequenced, and the length of the obtained DNA fragments were 611–614 bp in all samples. The homology of DNA sequences among samples was analyzed with the DNAMAN V6 software, and the phylogenetic tree among samples was established. Thirteen...
