Figure 1

Partial genetic map of the Volvox carteri mitochondrial genome compared to the complete mtDNA genetic map of Chlamydomonas reinhardtii. Protein-coding regions are yellow and their exons are labelled with an "E" followed by a number denoting their position within the gene. Introns and their associated open reading frames are orange. Transfer RNA-coding regions are red; they are designated by the single-letter abbreviation of the amino acid they specify. The large-subunit and small-subunit rRNA-coding modules are green. Arrows within the coding regions denote their transcriptional polarities. Solid red arrows perpendicular to the genome map indicate regions of the genome assembly where sequence data is either unreadable or lacking. The mtDNA regions that were previously sequenced and described by Aono et al. [17] are underlined in pink on the genome map. Gray blocks highlight regions of synteny between the V. carteri and C. reinhardtii mitochondrial genomes. Note: the optional group-I intron in cox1 is found in the mtDNA of V. carteri strain HK10 (UTEX 1885); this intron is absent from V. carteri strain 72-52 (UTEX 2908) – the C. reinhardtii strains in which the different introns occur are listed in [50].
