The mitochondrial genome sequence of Ceratozetella imperatoria (Aoki, 1963) (Acari: Ceratozetidae): Genome characterization and phylogenetic analysis</p >

Abstract

Oribatid mites play a crucial role in nutrient cycling, litter decomposition, and humus formation in the ecosystem. Here, an Illumina HiSeq platform was used to sequence the complete mitochondrial (mt) genome of Ceratozetella imperatoria. The mt genome is a circular molecule of 14,229 bp (GenBank number: PP419053), and a total of 37 genes were described. The start codon in all 13 protein-coding genes (PCGs) included ATT, ATA, TTG, and ATG, the stop codon of all 13 protein-coding genes was TAA, TAG, and single T. The AT skew and GC skew were 0.153 and 0.263 observed across the whole mt genome of Ceratozetella imperatoria. Besides the negative AT skew in PCGs, rRNA and CR, positive AT skew and GC skew were detected in the remaining components. A phylogenetic tree of 29 mite species was constructed using PCGs by the maximum likelihood method. Ceratozetoidea and Oripodoidea were closely related and become sister group relationships among them.
