| Abstract: | Four spiny lobster species, Panulirus
versicolor, P. ornatus, P. homarus
and P. polyphagus, and a mud lobster Thenus orientalis
were collected from the Gulf of Mannar marine biosphere reserve. Partial 28S
rRNA gene sequences of the spiny lobsters were examined for their nucleotide
diversity, pairwise genetic distances, transition/transversion rate and
phylogenetic relationships. The spiny lobster species recorded higher
transition over transversion; GC content was also higher as reported in many
groups of animals. Pair-wise genetic distance analysis shows that all the spiny
lobsters were distinctly distant from the outgroup species and had minimum
distance among the ingroup species. A molecular phylogeny based on 28S rDNA D2
sequences indicates that the four species of Panulirus form a
monophyletic group. |
