Abstract

Poplar (Populus spp.) leaf rusts caused by Melampsora species are considered among the most crucial sanitary problems threatening poplar stands worldwide. Several major resistance factors specific to poplar rusts have been identified, each of them discovered by using a single Melampsora species. Most of them are inherited from Populus species that did not co-evolve with the pathogen. The origin and function of such “exapted” resistance are thus called into question.
