Breeding for inducible resistance

Abstract: Knowledge about mechanisms for induced plant resistance, and susceptibility, to pests and diseases is rapidly increasing. Such knowledge is useful when breeding for inducible resistance that is aimed to be specific, efficient and with small costs to the plant. The inducing agents can be the pests or diseases themselves or resistance-inducing compounds. However, antagonism between plant defences to biotrophic and necrotrophic organisms is a problem that must be taken into consideration.
