First complete mitochondrial genome from the genus Coptodryas (Coleoptera: Curculionidae: Scolytinae) and its phylogenetic implications

Abstract

The complete mitochondrial genome (mitogenome) of Coptodryas elegans was determined, which represents the first sequenced mitogenome from Coptodryas . This mitogenome is 15,959 bp in size and comprises 36 typical coding genes and a control region, the tRNA Ile was not detected in this mitogenome, as observed in other species of Curculionidae. The monophyly of the family Scolytinae and the sister relationship between C. elegans and Cyclorhipidion bodoanus is supported by maximum likelihood analysis derived from the protein-coding gene sequences.

Characterization, comparative analyses, and phylogenetic implications of mitochondrial genomes among bark and ambrosia beetles (Coleoptera: Curculionidae, Scolytinae)

“…As reported in other insect mitogenomes, the 16S and 12S rRNA genes in Scolytinae species were encoded on the J-strand and located at conserved positions between trnL1 and trnV and between trnV and the control region, respectively (Guo et al, 2022b). The length of 16S ranged from 1,284 bp in E. similis to 1,477 bp in E. interjectus, and that of 12S varied from 777 bp in Xylosandrus sp.…”

“…Variations in the length of mitogenomes can be attributed to a variable number of repeats in the control regions. All the mitogenome contained 37 typical functional genes (i.e., 13 PCGs, 22 tRNA genes, and two rRNAs) and a control region (A + T-rich region), except for E. similis, wherein the trnI was not detected (Guo et al, 2022b;Xing et al, 2022). There was no difference between mitochondrial genes in order and orientation from the putative ancestral insect mitogenome (Cameron, 2014).…”
