Partial genetic map of the Volvox carteri plastid genome compared to the complete ptDNA genetic map of Chlamydomonas reinhardtii. Regions encoding proteins are yellow and their exons are labelled with an "E" followed by a number signifying their order 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. Ribosomal RNA-coding regions are green. The coding regions are shaped into arrows that denote their transcriptional polarities. Regions previously described by Aono et al. [17] are underlined in pink. Gray blocks highlight regions of synteny between the V. carteri and C. reinhardtii plastid genomes. Note, the true order of the V. carteri contigs are unknown.
