Genes regulated in the five P. microcarpus basidiocarp compartments. a Hierarchical clustering of 737 transcripts significantly regulated (>5fold, p-value < 0.05) between the five compartments. Unconsolidated peridioles (UP), Young peridioles (YP), Mature peridioles (MP), Internal spores (IS) and Free spores (FS). Over-represented (red) or under-represented (green) transcripts are shown as log₂ fold changes relative to the mean expression level measured across all five compartments. Letters to the left indicate clusters (see Additional file 4 for data). EPCLUST software was used for the hierarchical clustering b Number of regulated genes between basidiocarp compartments identified by pairwise comparison; the color intensity change with the number of genes c Functional classification of regulated transcripts using KOG groups. The numbers in parentheses represents the total number of up-regulated genes in each compartment
