Main features of the prasinophyte mitochondrial genomes compared in this study.

aThe Roman number refers to the phylogenetic clade identified by Guillou et al [18].bThe total number of unique genes is indicated outside the parentheses. The number inside the parentheses includes duplicated genes and intronic ORFs.cConserved genes (unique and duplicated), introns and intronic ORFs were taken into account.dThe total numbers of cis-spliced and trans-spliced introns are indicated outside and inside the parentheses, respectively.eNonoverlapping repeat elements were mapped on each genome with RepeatMasker using the repeats ≥30 bp identified with REPuter.
