The poplar-poplar rust pathosystem is a near-model system in forest pathology, in which years of breeding for resistance have seen each qualitative resistance type deployed overcome in due course by pathogen evolution. Working with the INRA Tree-Microbe Interactions group, I studied rapid changes in the poplar rust fungus (Melampsora larici-populina) in response to breeding for quantitative resistance in its host, testing whether new types of resistance-by-degree will be more durable to rust evolution.
