Nitric Oxide, an essential intermediate in the plant-herbivore interaction

Researchers from CBGP compile in a perspective article the role of nitric oxide (NO) and associated molecules with the NO metabolic pathway in the generation of plant defences to phytophagous insects and acari.


Reactive nitrogen species (RNS), mainly nitric oxide (NO), are highly reactive molecules with a prominent role in plant response to numerous stresses including herbivores, although the information is still very limited. This perspective article compiles the current progress in determining the NO function, as either a signal molecule, a metabolic intermediate, or a toxic oxidative product, as well as the contribution of molecules associated with NO metabolic pathway in the generation of plant defenses against phytophagous arthropods, in particular to insects and acari.
