dN/dS estimates in conifer and angiosperm genes across Arabidopsis' GO slim functional categories. Mean dN/dS values for conifer (full circle) and angiosperm (open circle) protein-coding genes. Conifer genes were BLASTed against Arabidopsis gene transcripts, whose GO Slim annotations were used for homologous conifer genes. Brackets represent the standard error of the mean. A: Biological processes; B: Molecular functions; C: Cellular component.
