Phylogenetic relationships of expressed chitinases. Phylogeny of chitinases showing two major fungal classes. Green branches highlight those chitinases of T. ophioglossoides. The T. ophioglossoides chitinase (TOPH_09828) upregulated on EMP (E. muricatus peridium media, represented by an asterisk), which is closely related to one of the four Tr. virens chitinases upregulated during mycoparasitism (represented by stars), as identified by Gruber et al. (2011). The most highly expressed T. ophioglossoides chitinase (TOPH_05538) in all conditions (represented by a ↑) is part of the Class III chitinases, a phylogenetically distinct group. Taxa sampled: Tr. virens, Tr. atroviride, Tr. reesei, Beauveria bassiana, Cordyceps militaris, Epichloë festucae, Claviceps purpurea, M. acridum, M. robertsii, O. sinensis, T. inflatum, and T. ophioglossoides.
