Cellular respiration is at the core of central metabo-lism, generating energy out of simple hydrocarbonmolecules. This energy runs fundamental functions ofthe cell. A collateral effect of aerobic metabolism is theproduction of reactive oxygen species (ROS) with po-tential to damage biological molecules and structures.The cell has myriad sets of mechanisms to control thedamage derived from respiration (Noctor and Foyer,2016). The chloroplast and mitochondria are the or-ganelles par excellence of ROS production that haveacquired different strategies to avoid or mitigate theirimpact (Huang et al., 2016). Interestingly, the ROSwithin organelles or at the inner side of the plasmamembrane can additionally help the plant under certainsituations, such as abiotic stress (Colombatti et al., 2019;Wang et al., 2020).
