Clustering of gene families according to their phylogenetic profiles. Clusters are indicated with roman numbers for A: non-pathogens and B: pathogens. Numbers on the left hand side indicate the number of gene families contained within each cluster (i.e. families with the same normalized phylogenetic profiles). The white-to-black scale, based on the gene family normalized phylogenetic profiles, indicates the size of the families in a cluster per species relative to the family-average (columns). Gene ontology terms of the overrepresented gene families in each cluster are shown at the right. AN: Aspergillus nidulans; AO: Aspergillus oryzae; NC: Neurospora crassa; TR: Trichoderma reesei; MG: Magnaporthe grisea; FG: Fusarium graminearum; MF: Mycosphaerella fijiensis; MYG: Mycosphaerella graminicola.
