Plant systemic induced responses mediate interactions between root parasitic nematodes and aboveground herbivorous insects
Insects and nematodes are the most diverse and abundant groups of multicellular animals feeding on plants on either side of the soil-air interface. Several herbivore-induced responses are systemic, and hence can influence the preference and performance of organisms in other plant organs. Recent studies show that plants mediate interactions between belowground plant parasitic nematodes (PPNs) an...
متن کاملInducible Plant Responses Linking Above- and Below-ground Herbivory: Ecological Significance and Underlying Mechanisms
Title: INDUCIBLE PLANT RESPONSES LINKING ABOVEAND BELOW-GROUND HERBIVORY: ECOLOGICAL SIGNIFICANCE AND UNDERLYING MECHANISMS Ian Kaplan, Doctor of Philosophy, 2007 Directed By: Professor Robert F. Denno, Department of Entomology Aboveand below-ground organisms can indirectly affect one another via several recently-described mechanisms, one such mechanism being herbivore-induced plant responses. ...
متن کاملPopulation Dynamics, Root Penetration, and Feeding Behavior of Pratylenchus agilis in Monoxenic Root Cultures of Corn, Tomato, and Soybean.
Population dynamics, rate of root penetration, and external root feeding behavior of Pratylenchus agilis (Pa) in monoxenic cultures of intact corn seedlings and root explants of corn, tomato, and soybean were studied. In descending order of suitability as hosts were I. O. Chief corn, Rutgers tomato, and Williams soybean. Soybean entries Kent, Pickett 71, PI 90763, and Essex were poor hosts. Num...
متن کاملAboveground insect herbivory increases plant competitive asymmetry, while belowground herbivory mitigates the effect
Insect herbivores can shift the composition of a plant community, but the mechanism underlying such shifts remains largely unexplored. A possibility is that insects alter the competitive symmetry between plant species. The effect of herbivory on competition likely depends on whether the plants are subjected to aboveground or belowground herbivory or both, and also depends on soil nitrogen level...
متن کاملPhysiological integration of roots and shoots in plant defense strategies links above- and belowground herbivory.
Roots play a critical, but largely unappreciated, role in aboveground anti-herbivore plant defense (e.g. resistance and tolerance) and root-leaf connections may therefore result in unexpected coupling between above- and belowground consumers. Using the tobacco (Nicotiana tabacum) system we highlight two examples of this phenomenon. First, the secondary metabolite nicotine is produced in roots, ...
