The roots of most land plants are colonised by mycorrhizal fungi that provide mineral nutrients in exchange for carbon. Here, we show that mycorrhizal mycelia can also act as a conduit for signalling between plants, acting as an early warning system for herbivore attack. Insect herbivory causes systemic changes in the production of plant volatiles, particularly methyl salicylate, making bean plants, Vicia faba, repellent to aphids but attractive to aphid enemies such as parasitoids.

It is demonstrated that AMF colonization alone does not enhance systemic defense responses, but that sectors of systemic responses in leaves can be primed by CMNs, suggesting that CMNs can transmit and even filter defense signaling among connected plants.

Interplant Communication of Tomato Plants through Underground Common Mycorrhizal Networks
- Environmental SciencePloS one

This finding indicates that CMNs may function as a plant-plant underground communication conduit whereby disease resistance and induced defence signals can be transferred between the healthy and pathogen-infected neighbouring plants, suggesting that plants can ‘eavesdrop’ on defence signals from the Pathogen-challenged neighbours through CMNs to activate defences before being attacked themselves.

The studies on the phenomena of herbivore-induced emissions of volatiles in corn and cotton plants and studies conducted by others indicate that the clarity of the volatile signals is high, as they are unique for herbivor damage, produced in relatively large amounts, and easily distinguishable from background odors.

It is found that inducible S-linalool attracted predators and parasitoids as well as chewing herbivores, but repelled the rice brown planthopper Nilaparvata lugens, a major pest, implying that the manipulation of volatile emissions in crops has great potential for the control of pest populations.
