First insights into specificity of belowground tritrophic interactions
Tritrophic interactions involving plants, herbivores and parasites have been only recently documented for belowground systems, where entomopathogenic nematodes can exploit root herbivore induced volatile compounds to locate their hosts. Little is known, however, about whether the specificity of such interactions rivals that of the remarkable interactions found in aboveground studies. Using a be...
متن کاملSystemic root signalling in a belowground, volatile-mediated tritrophic interaction.
Plants attacked by leaf herbivores release volatile organic compounds (VOCs) both locally from the wounded site and systemically from non-attacked tissues. These volatiles serve as attractants for predators and parasitoids. This phenomenon is well described for plant leaves, but systemic induction of VOCs in the roots has remained unstudied. We assessed the spatial and temporal activation of th...
متن کاملBacterial phytopathogen infection disrupts belowground plant indirect defense mediated by tritrophic cascade
Plants can defend themselves against herbivores through activation of defensive pathways and attraction of third-trophic-level predators and parasites. Trophic cascades that mediate interactions in the phytobiome are part of a larger dynamic including the pathogens of the plant itself, which are known to greatly influence plant defenses. As such, we investigated the impact of a phloem-limited b...
متن کاملSoil abiotic factors influence interactions between belowground herbivores and plant roots.
Root herbivores are important ecosystem drivers and agricultural pests, and, possibly as a consequence, plants protect their roots using a variety of defensive strategies. One aspect that distinguishes belowground from aboveground plant-insect interactions is that roots are constantly exposed to a set of soil-specific abiotic factors. These factors can profoundly influence root resistance, and,...
