Figure 2From: Evolution of spliceosomal introns following endosymbiotic gene transferThe tree represents current view of phylogenetic relationships between the lineages sampled in this analysis, as summarized by Roger and Simpson [60]. Inferred timing for the transfers of genes from the mitochondrion to the host nucleus is labeled at the branches. The timing of each transfer depends on the presence or absence of each gene in the mitochondrial genome and the phylogeny. Proto-mitochondrial genes of a) the oxidative phosphorylation pathway, b) ribosomal mitochondrial proteins.Back to article page
