Other claims from this paper (7)
- Observation Species-specific primers detected the native rust on aspen.
- Observation Exotic rusts M. medusae and M. larici-populina were not detected on aspen.
- Association Visible rust scores correlated with the amount of fungal DNA in the same leaf.
- Association At the genotype level, both positive and negative relationships were observed between condensed tannins, fungal markers and rust infestations.
- Association At the population level, foliar CT concentrations correlated negatively with general fungal- and rust-specific marker abundances.
- Recommendation Visible rust scores should not be used to assess Melampsora infestation in aspen.
- Observation The relationship between European aspen and rust infestation may be autochthonous in northern Sweden.
