Phylogentic and Evolutional Analysis of Acari by Mitochondrial Genome Arrangement Determination and Sequencing

Most of animal mitochondrial genome consisted of 37 genes and one control region. And also gene arrangement is rather conserved in their genome. However, we found that some mite species classified into Acariformes have different mitochondrial gene arrangement. So that we investigated whole mitochondrial genome sequencing in order to determine their phylogenetic disposition of such organisms. The results showed the unique gene order in the species and supposed that frequent and drastic gene rearrangement occurred in the mite group at levels of the evolutionary ladder.
