Genome evolution in Trichoderma. a time scaled evolutionary tree: red branches indicate only gains; blue branches only losses; black branches both gains and losses. Numbers over the branches indicate the number of gene changes per Mya; numbers below the branches indicate the number of gains (red) and losses (blue). b Heat map representing Pfam domains identifiend for OrthoMCL clusters that we gained or lost in the course of Trichoderma evolution. Framed rectangules correspond to extant species. Pale color used for hypothetical taxonomic units (HTUs, ancestral states). c. Principal component analysis based on the number of genes per each Pfam group that have been influenced by gene gain and loss in Trichoderma. Filled cicles correspond to extant Trichoderma species as shown on A. Grey circles correspond to HTUs per each infrageneric group (see a and b). Bold lined circles show the ancestral node for the respective section or clade. Circles with red/yellow and orangy/blue color show the ancestral node for the genis Trichoderma and SL/HV groups
