Fig. 1: Distribution of system I and system III genes for mitochondrial CCM in sequenced Archaeplastida species.
From: Recurrent evolutionary switches of mitochondrial cytochrome c maturation systems in Archaeplastida
The boxes indicate the presence (black or blue), absence (white), or uncertain status (gray with question mark) of system I and III CCM genes in each species. Species in blue lack system I but possess system III, and the inferred shifts from system I to III were counted and mapped onto the phylogenetic tree, whose relationships are based on recent studies93,94. The status of ccmB is uncertain in Galdieria40.
