We have sequenced the mitogenome of Coleochaete scutata strain SAG 110.80M. This mitogenome is the largest among the streptophyte green algae examined to date. At 242,024 bp, it is 4.3-fold larger than the mitogenome of Chaetosphaeridium globosum, the only other mitogenome available for the Coleochaetophyceae. This size difference is mainly explained by differences in the abundance of introns and in the length of intergenic regions containing vestiges of coding sequences thought to be of foreign origin. With 31 group I and 26 group II introns, the C. scutata mitogenome is the most intron-rich organelle genome known among streptophyte algae.
