Characterization of complete mitochondrial genome of Japanese sponge crab Lauridromia dehaani (Rathbun, 1923)

Abstract

The complete mitochondrial genome of Japanese sponge crab Lauridromia dehaani was first determined and characterized from South China Sea. The L. dehaani mitogenome is 15,754 bp in length, and consists of 22 tRNA genes, two rRNA genes, 13 protein-coding genes (PCGs), and one control region. The nucleotide composition of L. dehaani mitogenome is significantly biased (A, G, T, and C was 36.23%, 9.71%, 35.12%, and 18.94%, respectively) with A + T contents of 71.35%. Two PCGs used an unusual initiation codon, and eleven PCGs were terminated with an abnormal stop codon. Three microsatellites were identified in L. dehaani mitogenome sequences. Phylogenetic tree showed that L. dehaani was first clustered with Dynomene pilumnoides.
