Abstract:
In this study, we sequenced the complete mitogenome of Kentrochrysalis streckeri (Staudinger, 1880). The complete mitogenome sequence of K. streckeri is circular, 15,253 bp in size and contains 13 protein-coding genes (PCGs), two ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes, and a control region (CR). Nucleotide composition was A + T biased, and all the PCGs exhibited a positive AT-skew, which was reflected in the nucleotide composition, codon, and amino acid usage. Most PCGs start with ATG or ATT and stop with TAA. However, COX1 gene starts with CGA and three genes (COX1, COX2, NAD5) use the incomplete stop codon T. Phylogenetic analyses showed that the relationship (K. streckeri+((Manduca sexta+Sphinx morio)+(Psilogramma increta+(Psilogramma menephron+Notonagemia analis scribae)))).
