Résumé
Mitochondrial genomes (mitogenomes) typically contain 13 protein-coding genes, 22 tRNA genes, two rRNA genes, and a single control region (CR). Flatfish mitochondrial genomes (mitogenomes) from three different genera in Bothidae (bothids) contain double CRs that evolved in a concerted manner. How these double CRs maintained identical sequences throughout the evolutionary process is an interesting issue. In the present study, over four hundred arrays of the double CRs of mitogenomes from three bothids (Arnoglossus tenuis, Lophonectes gallus and Psettina iijimae) were performed. Interesting variations between double CRs were observed in P. iijimae mitogenomes, and the networks of CR sequences from P. iijimae indicated a high possibility of genetic information exchange between CRs. No recombination product was detected in our results, indicating that the mechanism of the concerted evolution between the double CRs of P. iijimae was not recombination. We speculate that mismatch repair, a mitochondrial DNA repair mechanism, is a potential explanation for the concerted evolution between these double CRs.
