My primary interests are the possible reproductive conflicts of interest that can arise between hosts and symbionts in mutualistic relationships. Such conflicts most probably have a negative impact on the outcome of the cooperation between partners in such relationships. Thus, mechanisms to prevent them are expected to be present and align the interests between partners. Leaf-cutting ants are ideal for studying such possible conflicts since they host two mutualistic microorganisms:1. A basidiomycete fungus that serve as the primary food source for the ants, and 2. A Streptomyces bacterium that serves a specific defence function against a potentially virulent pathogen of leaf-cutting ant fungus gardens.
