Chemical signals involved in plant-insect interactions
Plants under attack by herbivores initiate the production and release of volatiles that are attractive to the natural enemies of the herbivores. Aboveground these volatile signals can attract parasitic wasps and predators that attack and kill the herbivores. Belowground such signals are attractive to insect-killing nematodes. The signals are also perceived by neighboring plants, which may then mobilize their own defenses. We aim to unravel the chemical and molecular mechanisms that are involved in these interactions, as well as understand their ecological consequences. By studying cultivated plant and their wild ancestors we hope to develop methods to better exploit the natural defense signals for optimal crop protection.
