Question

Effect of heat stress on antioxidative enzymes in brassica

Answer 1

Answer:

Significant changes occur in antioxidant defenses in plants subjected to environmental stresses, including enzymatic and nonenzymatic antioxidants. The association of the antioxidant enzymes (SOD, CAT, and GR) and several others enables to keep the oxidative damages on the plant intracellular components to a very low level.7 For this reason, we measured the activity of the three antioxidant enzymes (SOD, CAT, and GR) under two conditions of thermal stress (12 and 32 °C) and under the optimal temperature (20 °C).
