Peroxisomes can be broadly defined as subcellular organelles bounded by a single membrane that contain as basic enzymatic constituents catalase and hydrogen peroxide (H2O2)-producing flavin oxidases and occur in almost all eukaryotic cells (Baker and Graham, 2002). In recent years, it has become increasingly clear that peroxisomes carry out essential functions in eukaryotic cells (Baker and Graham, 2002; del Rıo et al., 2002; Igamberdiev and Lea, 2002; Titorenko and Rachubinski, 2004). The peroxisome of plant cells is a highly dynamic compartment that is dependent upon the actin cytoskeleton, not microtubules, for its subcellular distribution and movements (Minorsky, 2002). These organelles have an essentially oxidative type of metabolism, and a characteristic property of peroxisomes is their metabolic plasticity, because their enzymatic content can vary depending on the organism, cell/tissue-type, and …
