Relationship between phylogenetic categories of genes coding for mitochondrial proteins and their MFI values. Mitochondrial proteins were previously grouped into four classes corresponding to: SC, 56 genes specific to S. cerevisiae; E, 115 genes with homologs in eucaryotes exclusively; BE, 80 genes with homologs in bacteria and eucaryotes; ABE, 100 genes with homologs in archaea, bacteria and eucaryotes. Genes of prokaryotic origin are in red, and those of eukaryotic origin in green. Bars are Tukey-Cramer 99% confidence intervals. This graph shows a very significant effect of the prokaryotic/eukaryotic origin of genes on the MFI of their mRNAs.
