Volatiles from Low R: FR-Treated Maize Plants Increase the Emission of Herbivore-Induced Plant Volatiles in their Neighbors.

ABSTRACT: Low Red (R) to Far Red (FR) light ratios, a light signal associated with vegetation shade, can prompt intact maize (Zea mays) plants to constitutively emit more volatiles when exposed to herbivory-induced plant volatiles (HIPVs). Here we investigated how simulated shading affects priming responses in the context of volatile-mediated plant-plant interactions. Receiver maize plants were exposed to either constitutive volatile organic compounds (cVOCs) or HIPVs from emitter maize plants, while we manipulated R: FR light conditions of receivers or emitters. Priming responses in the receivers were then assessed by measuring real-time volatile emissions following simulated herbivory. We show that low R: FR light enhances HIPVs emissions in plants previously exposed to HIPVs from neighbours indep
