Trophic dynamics in the fine-root based food web: integrating resource heterogeneity, root herbivores, and root foraging
… We know that plant species differ in their root responses to nutrient patches and that these differences in foraging can influence plant competition. However, most studies of root-resource interactions overlook the potential top-down influence of root herbivores. While root herbivores can …

Fine Root Dynamics in a Pinus palustris Mill. Ecosystem: The Role of Sampling Interval and the Soil Environment
… examined the impact of sampling interval on fine root production and mortality estimates by comparing data from a weekly minirhizotron sampling regimen to subsets of the same data representing biweekly, monthly, bimonthly, and quarterly sampling regimens. We also investigated possible sources of …

Aspects of the root ecology of Neotyphodium endophytes in Lolium perenne
… ryegrass (Nil) for their effects on root herbivory, soil biota, root growth, root morphology and alkaloid and nutrient content in pot trials. Ryegrass infected with the endophyte strain, AR37, which produces janthitrem alkaloids, was toxic to a root aphid, Aploneura lentisci. Relative …

Molecular and Functional Characterization of Terpene Chemical Defense in Arabidopsis Roots in Interaction with the Herbivore Bradysia spp. (fungus gnat)
Roots and leaves are integrated structural elements that together sustain plant growth and development. Insect herbivores pose a constant threat to both above- and belowground plant tissues. To ward off herbivorous insects, plants have developed different strategies such as direct and indirect …

Cell-type specificity and herbivore-induced responses of primary and terpene secondary metabolism in Arabidopsis roots
… changes of primary and secondary metabolism in roots of Arabidopsis thaliana. Roots represent important organs for anchoring plants in the soil and taking up water and nutrients. Hence, it is assumed that roots are as well protected as aerial tissues by different defense mechanisms. The first …
