Spectrofluorometric detection of superoxide anion (A), hydrogen peroxide (B), nitric oxide (C), peroxynitrite (D), and RSNO production (E) in tomato primary roots. The fluorescence produced is expressed in arbitrary units (AU) per μg of extract protein. At least five roots were tested for each experimental condition, and five independent repetitions were analyzed.
