- a The letter in parentheses indicates the chlorophyte lineage: P, Prasinophyceae; T, Trebouxiophyceae; U, Ulvophyceae; C, Chlorophyceae.
- b Conserved genes, unique ORFs and introns were considered as coding sequences.
- c Genes present in the IR were counted only once. Unique ORFs and intron ORFs were not taken into account.
- d Because Chlorella, Helicosporidium, Leptosira and Stigeoclonium cpDNAs lack an IR, only the total size is given for each of these genomes.
- e The gene repertoire of this alga was erroneously reported to include trnI(cau), explaining the difference with the gene number published previously [3, 7, 8].
- f This region was designated SC1 by de Cambiaire et al. [8] rather than LSC because it differs markedly in gene content relative to the LSC region in Mesostigma and Nephroselmis cpDNAs.
- g This region was designated SC2 by de Cambiaire et al. [8] rather than SSC because it differs markedly in gene content relative to the SSC region in Mesostigma and Nephroselmis cpDNAs.
