Abstrakt: Chlorosarcinopsis eremi is a member of Chlamydomonadales algae which is isolated from terrestrial environments. In this study, the mitochondrial genome of C. eremi isolated from desert region of Iran, was represented for the first time. Following sequencing, assembly and annotation, comparative analyses of C. eremi and other available Chlamydomonadales algae complete mitochondrial genomes were performed. The mitochondrial genome of C. eremi was circular, had a low number of genes coding in the same strand with a minor amount of repeated sequences; same as other non-Reinhardtinia species of Chlamydomonadales algae. GC content of C. eremi mitochondrial genome was in normal range when compared with non-Chlamydomonadales organisms, but among Chlamydomonadales algae, C. eremi had a low GC content mitochondrial genome. C. eremi had the highest percent of non-coding sequences in comparison with other available Chlamydomonadales mitochondrial genomes which was related to intergenic regions. Identity analysis of protein-coding sequences of Chlamydomonadales mitochondrial genomes showed more divergences and may be related to the high mutation rate of mitochondrial genome reported in microbial eukaryotes.
