Antioxidant enzymes efficiently control leaf and root cell damage in young Euterpe oleracea plants exposed to waterlogging

Antioxidant enzymes efficiently control leaf and root cell damage in young Euterpe oleracea... Euterpe oleracea (Mart.), an Amazonian palm, is of economic importance due to the production of energy drinks. Plants exposed to waterlogging are prone to damage at the cellular level and cause irreversible metabolic dysfunctions leading to cell death. This study was aimed to study cell damages and to investigate enzyme activities related to antioxidant system in this specie. The experimental design was in factorial randomized with two water conditions (waterlogging and control) and five evaluation times (0, 6, 12, 18, and 24 days). The parameters measured were electrolyte leakage (EL), contents of hydrogen peroxide (H2O2), malondialdehyde (MDA) and glutathione (GSH), and enzymatic activities of catalase (CAT), ascorbate peroxidase (APX) and peroxidase (POX) in leaf and root tissues. Waterlogging did not promote significant modifications in EL, MDA and H2O2 in both the tissues evaluated, and a minor alteration in GSH was observed only in the roots. Significant increases in the activity of CAT, APX and POX were observed in leaf and roots, at early stages. It can thus be concluded that CAT, APX and POX were efficient in controlling EL and MDA in leaf and root of E. oleracea plants under waterlogging. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Indian Journal of Plant Physiology Springer Journals

Abstract

Euterpe oleracea (Mart.), an Amazonian palm, is of economic importance due to the production of energy drinks. Plants exposed to waterlogging are prone to damage at the cellular level and cause irreversible metabolic dysfunctions leading to cell death. This study was aimed to study cell damages and to investigate enzyme activities related to antioxidant system in this specie. The experimental design was in factorial randomized with two water conditions (waterlogging and control) and five evaluation times (0, 6, 12, 18, and 24 days). The parameters measured were electrolyte leakage (EL), contents of hydrogen peroxide (H2O2), malondialdehyde (MDA) and glutathione (GSH), and enzymatic activities of catalase (CAT), ascorbate peroxidase (APX) and peroxidase (POX) in leaf and root tissues. Waterlogging did not promote significant modifications in EL, MDA and H2O2 in both the tissues evaluated, and a minor alteration in GSH was observed only in the roots. Significant increases in the activity of CAT, APX and POX were observed in leaf and roots, at early stages. It can thus be concluded that CAT, APX and POX were efficient in controlling EL and MDA in leaf and root of E. oleracea plants under waterlogging.
