The complete mitochondrial genome of the longhorn beetle Xylotrechus grayii (Coleoptera: Cerambycidae)

Abstract

We sequenced the complete mitochondrial genome of the longhorn beetle, Xylotrechus grayii. The total length of the X. grayii mitogenome was 15,540 bp with an A + T content of 75.29%, consisting of 13 protein-coding genes (PCGs), 22 tRNA genes, 2 rRNA genes and an A + T-rich region. All the genes were arranged in the same order as that of the ancestral insect. All PCGs started with a typical ATN codon except for cox1 and nad1, which used TTG as start codon. Ten out of 13 PCGs terminated with incomplete codons (TA or T). The A + T-rich region was 893 bp in length with an A + T content of 85.89 %.
