Hypothesis
M. pinitorqua infections predispose the trees to D. sapinea by stressing the host and altering the shoot metabolites.
Conclusion
The presence of M. pinitorqua symptoms on the shoot was a stronger predictor for changes in metabolite profiles than the fungal biomass.
Supporting Evidence
- Symptoms of both pathogens were consistent over years.
- Some trees showed disease tolerance with minimal symptoms.
- M. pinitorqua infection does not directly impact D. sapinea colonisation.
Takeaway
This study looked at how two fungi affect Scots pine trees. Some trees got sick, while others stayed healthy, showing that trees can be strong against these infections.
Methodology
The study involved sampling Scots pines over time to analyze pathogen biomass and host metabolites.
Potential Biases
Potential bias in selecting trees based on visible symptoms.
Limitations
The study was limited to a specific site and may not represent all Scots pine populations.
Participant Demographics
Scots pine trees in a plantation in Västmanland, Sweden.
