Abstract: Understanding why nitrogen fertilization increase the impact of diseases may explain the lack of efficiency of resistance inducers. We propose that in plants supplied with elevated nitrogen fertilization, the observed enhanced induction of plant defence is over-passed by an increase in the expression of the fungal pathogenicity program, thus leading to enhanced susceptibility.
