a
Numbers within parentheses indicate the number of genes in a particular class.
b
Gene identified as orf183 in Marchantia mtDNA, orf25 in angiosperm mtDNAs, and ymf39 in other green plant mtDNAs (Burger et al., 2003).
c
Different nomenclatures have been used to designate these genes in land plant mtDNAs (for Marchantia and Arabidopsis mtDNAs, see Turmel et al. [1999]; for sugar beet mtDNA, see Kubo et al. [2000]; and for rice mtDNA, see Notsu et al. [2002]).
d
Gene identified as orf244 in Marchantia mtDNA, ymf16 in Mesostigma mtDNA, tatC in sugar beet mtDNA, and orfX in rice mtDNA.
