Supplementary Table S6. Statistics on gene overlaps of tunicate mitochondrial genomes. Newly sequenced mt genomes are reported in bold. Aplouso = Aplousobranchia; Phlebo = Phlebobranchia; Stolido = Stolidobranchia; Thalia = Thaliacea. tot. bp = total length of the gene overlap; tot% = percentage in length of the overlapping regions; N° = number of overlapping regions; Max = length of the longest overlapping region; cox2-cob block = length of the overlap between the cox2 and cob genes.
