For Mesostigma mtDNA, the data were taken from ref. 8, whereas those for the Marchantia and Arabidopsis mtDNAs were taken from ref. 47.
*
Conserved genes, unique ORFs, introns, and intron ORFs were considered as coding sequences.
†
Unique ORFs, intron ORFs, and pseudogenes were not taken into account.
