Comparative mitogenomic and phylogenetic insights from four newly sequenced tick mitochondrial genomes.

ABSTRACT: Ticks, recognized as the second most significant vector of pathogens after mosquitoes, are of considerable interest in medical research. Although mitochondrial genomes are commonly employed in the phylogenetic studies of insects and arthropods, investigations into tick mitochondrial genomes are relatively scarce. The evolutionary and phylogenetic relationships at the family and genus levels remain unresolved. In this study, the mitochondrial genomes of Haemaphysalis warburtoni, Ixodes crenulatus, Rhipicephalus bursa, and Rhipicephalus pumilio were first sequenced and annotated based on the Illumina NovaSeq 6,000 platform, and compared with the mitochondrial genes of 150 other hard ticks. All examined tick mitochondrial genomes exhibit a notable AT bias, with A+T content rangi
