The mitochondria genome size ranges from <6 kilobase pairs (kbp) in Plasmodium falciparum (the human malaria parasite) to >200 kbp in land plants (Gray et al., 1999), which encode a limited number of mitochondria tRNAs, ribosomal proteins, essential subunits of the different respiratory chain complexes, and some components involved in cytochrome-c biogenesis (Marienfeld et al., 1999). This evidence concerns the gene CYCS and malaria.
