Bacterial 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 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 کاملTesting the Plant Growth-Defense Hypothesis Belowground:
According to the growth-defense hypothesis in ecology, studies suggest that a relationship between the ability of faster-growing plant species should suffer more from herbivores and plants to grow fast and the ability to defend themselves pathogens than slower-growing species. Tests of this hypothesis have focused on aboveground plant tissues, herbivores, and pathogens; however, it should also ...
متن کاملNitrogen enrichment differentially affects above- and belowground plant defense.
UNLABELLED PREMISE OF THE STUDY Human nitrogen (N) inputs to terrestrial ecosystems have greatly increased in recent years and may have important consequences for plant growth, reproduction, and defense. Although numerous studies have investigated the effects of nitrogen addition on plants, few have examined both above- and belowground responses within a range of predicted increase and apart...
متن کاملIndirect defence via tritrophic interactions.
Many plants interact with carnivores as an indirect defence against herbivores. The release of volatile organic compounds (VOCs) and the secretion of extrafloral nectar (EFN) are induced by insect feeding, a response that is mediated by the plant hormone, jasmonic acid. Although VOCs mainly attract predatory mites and parasitic wasps, while EFN mainly attracts ants, many more animal-plant inter...
