Gluconeogenesis of lipid reserves within aleurone cells, which supports this hydrolytic enzyme synthesis, results in the generation of H (2) O (2), which is catabolized by glyoxysomal catalase.

In the present study, the influence of subchronic effects of two plant growth regulators (PGRs) [Abcisic acid (ABA) and Gibberellic acid (GA3)] on antioxidant defense systems [reduced glutathione (GSH), glutathione reductase (GR), superoxide dismutase (SOD), glutathione-S-transferase (GST) and catalase (CAT)] and lipid peroxidation level (malondialdehyde = MDA) in various tissues of the rat were investigated during treatment as a drinking water model. 75 ppm of ABA and GA3 in drinking water were continuously administered orally to rats (Sprague-Dawley albino) ad libitum for 50 days.

Catalase activity increased, and hydrogen peroxide concentration decreased in transgenic tomato plants compared with the wild-type plants with or without water deficit stress.

The study was aimed at demonstrating changes in the antioxidant defense systems [Reduced glutathione (GSH), glutathione reductase (GR), superoxide dismutase (SOD), glutathione-S-transferase (GST) and catalase (CAT)] forming an antioxidative barrier and oxidative stress parameter (Malondialdehyde=MDA) in the various tissues of Sprague-Dawley rats which were administrated plant growth regulators (PGRs) [Abcisic acid (ABA) and Gibberellic acid (GA (3))] during 25 days.

Normal and diabetic rats (Albino -wistar strain) were administered 50 microg HB and GBA intradermally each day for seven days and their tissue and blood levels of malondialdehyde (MDA), 4-hydroxy-2-nonenol (4-HNE), reduced glutathione (GSH) content and catalase (CAT) activity were determined.

The sensitivity of GA-treated aleurone to light and H (2) O (2) is a result of lowered amounts of enzymes that metabolize AOS. mRNAs encoding catalase, ascorbate peroxidase and superoxide dismutase are all reduced during 6-18 h of incubation in GA, but these mRNAs were present in higher amounts in cells incubated in ABA.

The activity of the catalase enzyme is also increased by the rising level of magnesium, which has a protective effect on auxins.

Gibberellins (GAs) initiate a series of events that culminate in programmed cell death, whereas abscisic acid (ABA) prevents this process.
The amounts and activities of ROS scavenging enzymes, including catalase (CAT), ascorbate peroxidase, and superoxide dismutase are strongly down-regulated in aleurone layers treated with GA.
