Model proposed for the production of O2·− radicals and function of antioxidative enzymes of the ascorbate-glutathione cycle in leaf peroxisomes. The model is based on results described by different authors (del Río et al., 1998, 2002; López-Huertas et al., 1999). ASC, Ascorbate, reduced form; DA, dehydroascorbate, ascorbate oxidized form; DAR, dehydroascorbate reductase; GSH, glutathione, reduced form; GSSG, glutathione, oxidized form; MDA, monodehydroascorbate.

Hypothetical model of the role of peroxisomes in the generation of the signal molecules H2O2, O2·−, NO·, and GSNO. Cytochrome b, a b-type cytochrome (PMP18); GSNOR, GSNO reductase; XOD, xanthine oxidase. Broken arrows indicate signaling.
