Indeed, the comparative analysisof genes and genomes can provide useful information on their origin andon the mechanisms involved in their evolution. This includes understanding how specific biochemical pathways, protein complexes or cellular organelles emerged and evolved as well as using this evolutionary information to gain insight into their function. The hypothesis of this work was that a comparative genomics of those species of Trichoderma which are most frequently sampled (and therefore must be most successful generalists) and an analysis of their pattern of gene evolution would reveal the evolutionary events that shaped the nutritional expansions and environmental generalism. We show how PLAZA provides a versatile platform for integrating published plant genomes to study gene function and genome evolution. Our research interests are focused around the use of comparative genomics and phylogenomics to study the origin, evolution and function of complex biological systems.
