Standardized transcription values (RPKM) for cell wall degrading enzymes in Zymoseptoria tritici that showed significant values of diversifying or purifying selection according to McDonald–Kreitman tests. Genes are color-coded according to the evolutionary scenario to which they were assigned (see also figs. 4 and 5). The gene expression bars represent the average from three biological replicates and error bars are one standard deviation from the mean; dpi, days post-inoculation. Detailed values are given in supplementary table S2, Supplementary Material online.
