Abstract
Reactive oxygen species (ROS) are recognized as important signaling components in various processes in plants. ROS are produced for NADPH oxidase in different subcellular compartments and they are involved for a wide range of stimuli, such as cell cycle, growth, plant defenses, abiotic stress responses, and abscisic acid signaling in guard cells. In Arabidopsis, root hairs ROS also play a key role in root hair growth and they control the activity of calcium channels required for polar growth (Takeda et al. Science 319:1241–1244, 2008). The production of reactive oxygen species is under a specific molecular control in order to avoid detrimental side effects. Here we describe a protocol to detect ROS by oxidation of a derivative of fluorescein: 2′,7-dihidro dicloro fluorescein (H2DCFDA).
