From: The economics of organellar gene loss and endosymbiotic gene transfer
Selection coefficients for retention (SR, gray) or endosymbiotic gene transfer (SEGT, green) of all genes encoded in the example alphaproteobacterial and cyanobacterial genomes. Coefficients were computed accounting for protein abundance, host cell organellar fraction, organellar genome copy number per cell, and host cell energy consumption. The plots shown are for a simulated host cell comprising 1 × 107 proteins and a protein import cost of 2 ATP per residue, plots for other host cell protein contents and protein import costs are provided in Additional file 1: Fig. S2-S7. A Selection coefficients of all genes encoded in the alphaproteobacterium genome. B Selection coefficients for all genes encoded in the cyanobacterial genome. SR and SEGT have opposite signs (see the “Methods” section). To simplify the display and enable direct comparison, the absolute value of the selection coefficients of each gene is plotted, and green shading is used to indicate genes in the SEGT fraction and gray shading indicates genes in the SR fraction of the genome.
