Relationship between amino acid similarity and expression conservation. a Plot of FPKM ratio of orthologs (Ph. infestans divided by Py. ultimum) in early tuber versus amino acid identity. Orange and blue symbols represent members of multigene families and single-copy genes, respectively. b Box-plots indicating variation in expression level in early rye (based on 5273 genes with FPKM ≥ 1), early pea (5211 genes), early tuber (5123 genes), and late tuber (5461 genes) as a function of amino acid identity. Similar trends were seen in late rye and pea. Variation is defined as the difference between the FPKM of orthologs divided by their summed FPKM values. Ratios above 200 or below 0.01 are graphed as 200 and 0.01, respectively
