The ancestral mycoparasitic lifestyle of Trichoderma (Kubicek et al., 2011; Druzhinina et al., 2011) may explain the unusually diverse repertoire of biosynthetic clusters, particularly in Trichoderma atroviride (Hypocrea atroviridis) and Trichoderma virens (Hypocrea virens), as a large array of compounds would be necessary
in the attack against other microbes. These two species are aggressive mycoparasites, while the weakly mycoparasitic,
biomass-degrading Trichoderma reesei (Hypocrea jecorina) has less diversity (Kubicek et al., 2011). Mycoparasitism
represents the culmination of competition for resources between Trichoderma and its host fungi. Based on the idea
that the evolution of SM production was indeed driven by competition between species, a recent proposal is that the
many silent biosynthetic clusters could be activated by competition or by conditions that simulate the normal
route of activation
