Identification of the complete mitochondrial genome of Monomia gladiator (Decapoda: Brachyura: Portunidae) and its phylogenetic relationship

摘要

AbstractThe complete mitochondrial genome sequence plays an important role in phylogenetic studies. In this study, the complete mitochondrial genome of Monomia gladiator was obtained by Illumina and Sanger sequencing techniques. The circular genome was 15,878?bp in length, consisting of 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and a putative control region. This whole mitogenome composition was 33.32% for A, 35.69% for T, 11.75% for G, and 19.24% for C, respectively. The phylogenetic analysis suggested that M. gladiator was genetically closest to three Portunidae species (Charybdis japonica, C. feriata and Thalamita crenata). The newly described mitogenome may facilitate the phylogenetic studies on Portunidae crabs.
