Saving the world's food supply constitutes one of the major challenges of the future.
As a complement to classical and molecular breeding technologies, novel strategies
for biotechnological improvement of plant immunity aim at enhancing host recognition
capacities for potential pathogens, at boosting the executive arsenal of plant immunity,
and at interfering with virulence strategies employed by microbial pathogens. In addition,
chemical and biological priming provides means for triggering plant defenses in a
non-transgenic manner. Major advances in our understanding of the molecular basis
of plant immunity and of microbial infection strategies have opened new ways for engineering
durable disease resistance in crop plants that are highlighted in this review.
