Protein-protein interactions (PPIs) play a key role in various aspects of the structural and functional organization of the cell. Knowledge about them unveils the molecular mechanism of biological processes. TrichodermaGMD contains 52,556 interactions of 6 Trichoderma species. The PPIs were inferred via the ortholog-based interaction inference method with evidence from PPIs of 8 Trichoderma species (https://cn.string-db.org) and 6 different yeast types (http://interactome.dfci.harvard.edu/)
