| Abstract | (Thenus unimaculatus or a purple-legged shovel-nosed lobster is one of three Thenus species found in Thailand. Shovel-nosed lobsters have been increasingly consumed and this could give a great threat to T. unimaculatus which has a narrow range of distribution, found only in Andaman Sea. Genetic diversity study of the purple-legged shovel-nosed lobster is therefore needed for evaluating its current genetic status. In this study, 71 specimens of T. unimaculatus were collected from five provinces along Andaman Sea coastline. 12s ribosomal RNA (12s rRNA) and cytochrome C oxidase subunit I (COI) mitochondrial genes were PCR amplified. The 12S rDNA and COI nucleotide sequence alignments of 60 and 70 samples, respectively, were successfully prepared, suggesting that the parsimony informative sites of COI gene was higher than that of 12s rDNA. Phylogenetic analysis using Maximum Likelihood method revealed that populations of T. unimaculatus in Thailand were fairly homogenised. This blended genetic diversity among the five provincial populations could indicate the circulation of its planktonic larvae, resulting from two different patterns of sea currents of Andaman Sea.) |
