- Abstract
- Reactive oxygen species (ROS), including hydrogen peroxide (H2O2), are important inter- and intracellular signaling molecules involved in various plant physiological processes under biotic and abiotic stress conditions. They are produced in different subcellular compartments such as apoplast, plasma membrane, chloroplasts, peroxisomes, and mitochondria. Under stress, H2O2 is mainly produced in the apoplast by plasma membrane localized respiratory oxygen burst oxidase homologs (RBOHs), dismutases, and cell wall peroxidases. The function of H2O2 as a signal requires its diffusion through the plasma membrane or internal membranes, a process that is facilitated by the presence of channels named aquaporins (AQPs). In this chapter, we will discuss the mechanisms by which AQPs facilitate and regulate H2O2 membrane diffusion, and the relevance of their contribution in organellar, cellular, and cell-to-cell H2O2 signaling processes in the context of abiotic and biotic stresses.
