WebAug 1, 2013 · Introduction. Nitric oxide (NO), a diatomic free radical gas, and reactive oxygen species (ROS), such as superoxide anion (O2 −) or hydrogen peroxide (H 2 O 2), are involved as central signaling molecules in a wide range of physiological processes in plants [1, 2]. ROS are permanently produced in chloroplasts, mitochondria and … WebMay 1, 2024 · Nitric oxide (NO) is a redox, gaseous, highly reactive nitrogen species (RNS) produced in living cells under normal as well as under conditions of biotic and abiotic stress. When the concentration of ROS becomes toxic to a plant, NO may act as a detoxifier and minimize any detrimental effects ( Lipton et al., 1993 ).
