Life history

Expanding the framework for ecology, evolution and life history of plant pathogens

Research on the biology, ecology and evolution of plant pathogens has been markedly agrocentric, leading to concepts of disease cycles and pathogen life histories that are focused on agricultural settings at time scales corresponding mostly to cropping seasons and plant developmental stages.

The MISTRAL team has been specifically exploring a more comprehensive perspective on the ecology and biology of Pseudomonas syringae and Botrytis cinerea concerning the habitats and environmental factors that mold the behavior and influence the diversification of these pathogens and that could lead to more efficient strategies of disease management.

Rather than restricting our interest to deleterious effects of plant pathogens, we are exploring, where relevant, the beneficial aspects of these organisms for plant health and for the environment. This leads us to raise questions about how to balance these possible beneficial traits with the risk of disease.
