Mitochondrial genome of Taiwania circumdata (Coleoptera: Chrysomelidae: Cassidinae) and phylogenetic analysis.

ABSTRACT: In this study we sequenced and annotated the nearly complete mitochondrial genome (mitogenome) of Taiwania circumdata (Coleoptera: Chrysomelidae: Cassidinae), an important insect pest on sweetpotato and water spinach in Southern China. This mitogenome was 13,546 bp long and encoded 13 protein-coding genes (PCGs), 19 transfer RNA genes (tRNAs) and 2 ribosomal RNA unit genes. The T. circumdata mitogenome with an A + T content of 77.9% presented a positive AT-skew (0.126) and a negative GC-skew (-0.160). Eleven PCGs started with a typical ATN codon, whereas the remaining two PCGs used TTG (nad1) and AAT (cox1) as the initial codon. All the 19 tRNAs had a typical secondary cloverleaf structure, except for trnS1 (AGN) which lacked the dihydrouridine arm. Phylo
