Complete mitochondrial genome of the ornate rock lobster <i>Panulirus ornatus </i>(Crustacea: Decapoda)

Abstract

The ornate rock lobster Panulirus ornatus is an important commercial lobster in the world. In this study, we successfully amplified and sequenced the complete mitochondrial genome of P. ornatus. The DNA of P. ornatus is 15680 bp, containing 13 protein-coding genes (PCGs), two ribosomal RNA genes, 22 transfer RNA genes, and 1 AT-rich non-coding region. The sequence arrangement of P. ornatus mitochondrial genome and the structures of 32 mitochondrial genes were analyzed. Phylogenetic analyses, using 13 protein-coding genes of the mitochondrial genome with Bayesian inference (BI) and maximum likelihood (ML) methods were performed. ML analysis showed that Pleocyemata could be separated into five groups: Caridea, Palinura, Astacidea, Anomura and Brachyura, while BI analysis showed that Achelata and Astacidea could be presented as a sister group. Both the results of BI and ML supported that P. ornatus and Panulirus stimpsoni group together to form a monophyletic clade presented as the sister group to Panulirus japonicus.

Key words: Panulirus ornatus, mitochondrial genome, decapoda, phylogenetics.
