The complete mitochondrial genome of red-clawed crab Chiromantes haematochir (Sesarmidae: Grapsidae)

Abstract

The complete mitogenome of Chiromantes haematocheir is 15 899 bp in length contains the typical set of 37 genes, including 13 protein-coding genes (PCGs) (ATP6, ATP8, COI-III, ND1-6, ND4L, and Cyt b), two rRNAs (12S rRNA and 16S rRNA), 22 tRNAs, and a putative CR (D-loop). All PCGs start with an ATG codon except ND1 start with ATT and ND3 start with ATA. TAA is the most frequent stop codon, although COI end with TA-, and COII stop with the single nucleotide T-. The new mtDNA sequence contains 12S rRNA and 16S rRNA of rRNAs, separated with tRNAval. All tRNAs possess the typical clover leaf secondary structure except for tRNASer(AGN) and tRNALeu(CUN), which lacks a dihydroxyuridine (DHU) arm. The CR is 826 bp in length, located between 12S rRNA and tRNAGlx. The phylogenetic trees support Chiromantes haematochir has close relative with Sesarmops sinensis and Sesarmane glectum.
