Beschreibung

This project will investigate the microbial communities with a focus on the mycobiomes that are associated with Douglas fir (Pseudotsuga menziesii) to understand their interactions with fungal pathogens. Although Douglas fir is increasingly used as a climate-adapted species, it is also vulnerable to opportunistic fungi that become pathogenic under stress. We will study the increasing incidence of co-infections causing shoot blight and needle cast by combining controlled drought-stress experiments with pathogen inoculations. In particular, on how hot drought affects pathogen behaviour, whether stress induces priming-based resistance, and how microbial communities shift under abiotic stress, including provenance-specific differences influencing disease outcomes and resilience. 

 

Objectives:

• Characterise the microbiome of young Douglas fir from natural stands with differing health status.
• Assess the susceptibility of Douglas fir saplings of various provenances to Diplodia sapinea, Dothistroma spp., and Rhabdocline pseudotsugae, including their co-infections, before and after controlled exposure to hot drought.

The Excellence Cluster Future Forests at the University of Freiburg is an interdisciplinary research center dedicated to questions of adaptation and transformation of forests and their societal use in the face of global change. Future-oriented research on the complex interactions between forests and society is conducted here with outstanding international visibility, supported by the German Research Foundation. Future Forests brings together more than 50 researchers from four faculties as well as non-university partner institutions.
