# Characterizing the complete mitogenome of Odontothrips phaseoli (Thysanoptera: Thripidae) and its mitochondrial phylogeny

## TL;DR

This paper reports the complete mitochondrial genome of Odontothrips phaseoli and explores its evolutionary relationships with related thrips species.

## Contribution

The study provides the first complete mitogenome of Odontothrips phaseoli and identifies gene rearrangements and phylogenetic patterns.

## Key findings

- The complete mitogenome of Odontothrips phaseoli is 15,540 bp long and contains 37 genes.
- Gene rearrangements are observed compared to the ancestral insect mitogenome.
- Odontothrips phaseoli clusters closely with Megalurothrips usitatus in the phylogenetic analysis.

## Abstract

Described originally from Heilongjiang, China, Odontothrips phaseoli is a potential pest of threatening bean plant in northern China. The complete mitochondrial genome of O. phaseoli 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 (atp8, nad1, nad2 and nad4) use an incomplete ‘T’ and nad6 employs TAG as the stop codon. Compared to the mitogenome of the ancestral insect, O. phaseoli displays significant gene rearrangement. However, it retains three conserved gene blocks in common with its related species, Megalurothrips usitatus, both of which belong to the Megalurothrips 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.
