Characterizing the complete mitogenome of <i>Odontothrips phaseoli</i> (Thysanoptera: Thripidae) and its mitochondrial phylogeny

Described originally from Heilongjiang, China, <i>Odontothrips phaseoli</i> is a potential pest of threatening bean plant in northern China. The complete mitochondrial genome of <i>O. phaseoli</i> was sequenced and assembled, with a total length of 15,540 bp. Within this genome, 37 genes have been identified: 13 PCGs, 22 tRNAs, two rRNAs, and two putative control regions. Most PCGs terminate with TAA, while four genes (<i>atp8</i>, <i>nad1</i>, <i>nad2</i> and <i>nad4</i>) use an incomplete ‘T’ and <i>nad6</i> employs TAG as the stop codon. Compared to the mitogenome of the ancestral insect, <i>O. phaseoli</i> displays significant gene rearrangement. However, it retains three conserved gene blocks in common with its related species, <i>Megalurothrips usitatus</i>, both of which belong to the <i>Megalurothrips</i> genus-group. The phylogenetic tree, constructed based on the entire mitogenome dataset of all thrips species available in NCBI, shows that the two species cluster closely together. This alignment might underscore the close link between gene arrangements and the phylogeny relationships.
