Identification and analysis of the complete mitochondrial genome of Phyllotreta striolata (Coleoptera, Chrysomelidae)

Abstract

In this study, the complete mitochondrial genome of Phyllotreta striolata (Coleoptera, Chrysomeloidea, Chrysomelidae) was first determined. The complete genome is 15,689 bp in length. It contains 13 protein-coding genes (PCGs), 22 tRNA genes, two rRNA genes, and a control region (A + T-rich region). The gene organization, nucleotide composition, and codon usage are similar to other Chrysomelidae mitogenomes. The overall nucleotide composition was 39.90% A, 35.94% T, 15.27% C, and 8.89% G, respectively. Phylogenetic analysis both highly supported that P. striolata showed a close relationship with P. undulata. The measure of complete mitogenome sequence of P. striolata will provide fundamental data for the phylogenetic and biogeographic studies of the Chrysomeloidea and Coleoptera.
