Trichoderma is a
genus of
fungi that is present in all soils, where they are the most prevalent
culturable fungi. Many species in this genus can be characterized as opportunistic avirulent plant symbionts. This refers to the ability of several
Trichoderma species to form mutualistic endophytic relationships with several plant species. The genomes of several
Trichoderma specieshave been sequenced and are publicly available from the JGI.
