Abstract
Trichoderma spp. are filamentous fungi which frequently colonise soil and plant roots. They are potent parasites of phytopathogenic fungi (mycoparasites) and some Trichoderma species are also able to induce systemic resistance in plants. Therefore, these fungi are commercially used as biological control agents as an alternative to synthetic pesticides.
The aim of this project is to develop and apply analytical methods for the study of the molecular mechanisms underlying the interactions of Trichoderma with both plants and phytopathogenic fungi.
So far we have developed GC-MS and LC-MS(/MS) based methods for the profiling of bioactive secondary metabolites such as peptaibiotics, siderophores and volatiles. In close cooperation with molecular biologists, mycologists and plant pathologists, we currently apply these methods to investigate the metabolome of Trichoderma as well as the molecular crosstalk of the fungus with its living environment.
We expect that the results of the project will provide a better understanding of the complex mechanisms involved in mycoparasitism and biocontrol.
