“…Inoculation of beneficial microbes near the root surface can have the indirect and unintended effect of altering the native microbial community near the roots of plants (Philippot et al, 2013), which in turn alters soil physicochemical properties and plant performance (Schnitzer et al, 2011;Lau & Lennon, 2012;Bever et al, 2013). Variation in soil properties has been shown to alter the efficacy of EPNs (Kawaka et al, 2001;Toepfer et al, 2010;Campos-Herrera et al, 2013). Therefore, the indirect effect of soil microbes on soil properties might influence plant recruitment of foraging EPNs, either through modification of the soil physicochemical structure that directly affects nematode movement and behavior, but also indirectly by altering the ways that VOCs propagate through the soil Rasmann et al, 2012).…”

Soil microbial mutualists of plants, including mycorrhizal fungi, nonmycorrhizal fungi and plant growth promoting rhizobacteria, have been typically characterized for increasing nutrient acquisition and plant growth. More recently, soil microbes have also been shown to increase direct plant defense against above-and belowground herbivores. Plants, however, do not only rely on direct defenses when attacked, but they can also recruit pest antagonists such as predators and parasitoids, both above and belowground, mainly via the release of volatile organic compounds (i.e., indirect defenses). In this review, we illustrate the main features and effects of soil microbial mutualists of plants on plant indirect defenses and discuss possible applications within the framework of sustainable crop protection against root-and shoot-feeding arthropod pests. We indicate the main knowledge gaps and the future challenges to be addressed in the study and application of these multifaceted interactions.
