  • Title: The complete mitochondrial genome of the Caribbean spiny lobster Panulirus argus.
    Author: Baeza JA.
    Journal: Sci Rep; 2018 Dec 06; 8(1):17690. PubMed ID: 30523272.
    Abstract:
    Panulirus argus is a keystone species and target of the most lucrative fishery in the Caribbean region. This study reports, for the first time, the complete mitochondrial genome of Panulirus argus (average coverage depth nucleotide-1 = 70×) assembled from short Illumina 150 bp PE reads. The AT-rich mitochondrial genome of Panulirus argus was 15 739 bp in length and comprised 13 protein-coding genes (PCGs), 2 ribosomal RNA genes, and 22 transfer RNA genes. A single 801 bp long intergenic space was assumed to be the D-loop. Most of the PCGs were encoded on the H-strand. The gene order observed in the mitochondrial genome of Panulirus argus corresponds to the presumed Pancrustacean ground pattern. KA/KS ratios calculated for all mitochondrial PCGs showed values < 1, indicating that all these PCGs are evolving under purifying selection. A maximum likelihood phylogenetic analysis (concatenated PCGs [n = 13], 154 arthropods) supported the monophyly of the Achelata and other infraorders within the Decapoda. Mitochondrial PCGs have enough phylogenetic informativeness to explore high-level genealogical relationships in the Pancrustacea. The complete mitochondrial genome of the Caribbean spiny lobster Panulirus argus will contribute to the better understanding of meta-population connectivity in this keystone overexploited species.
