The complete mitochondrial genome of two-spotted cricket Gryllus bimaculatus (Grylloidea: Gryllidae)

Abstract

The complete mitogenome of Gryllus bimaculatus is 16,301 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). ATT, ATG, and ATA are the most start codon. TAA is the most frequent stop codon. The new mtDNA sequence contains 16S rRNA and 12S rRNA of rRNA, which is located between tRNALeu and D-loop, separated by tRNAVal. All tRNA genes possess the typical clover leaf secondary structure except for tRNASer(AGN) and tRNALeu(CUN), which lacks a dihydroxyuridine (DHU) arm. The D-loop (1585 bp) located the end of mitochondrial genome sequences. The phylogenetic trees support Chiromantes haematochir has close relative with Velarifictorus hemelytrus and Teleogryllus emma.
