Characterisation of a novel soybean candidate glutathione peroxidase/thioredoxin-dependent peroxidase in soybean exposed to osmotic/drought stress
(University of the Western Cape, 2012)Drought stress is a major contributor to reduced soybean crop yield and quality, this can however be mitigated by the plant’s antioxidant defence mechanisms. One group of antioxidant enzymes that are active in these defence ... -
Characterization of a novel soybean candidate glutathione peroxidase/thioredoxin-dependent peroxidase under salt stress
(2012)The production of reactive oxygen species (ROS) is prominent in all aerobic metabolisms including plants. For this reason, the redox homeostasis of the production and scavenging of these intermediates is imperative for ... -
Impact of vanadium stress on physiological and biochemical characteristics in heavy metal susceptible and tolerant Brassicaceae
(University of the Western Cape, 2013)There is an influx in heavy metals into soils and ground water due to activities such as increased mineral mining, improper watering and the use of heavy metal contaminated fertilizers. These heavy metals are able to ... -
Involvement of abscisic acid and H2O2 in antioxidant enzyme activities mediated by nitric oxide synthase-like activity in maize
(University of the Western Cape, 2018)In recent years, nitric oxide (NO) has emerged as an important endogenous plant signalling molecule that mediates many developmental and physiological processes. NO regulates the activity of antioxidant enzymes in response ... -
Methylgyoxal signalling in Phaseolus vulgaris under phosphate deficiency
(UWC, 2020)In this study, we observed that phosphate (P) deficiency stunted plant growth and produced plants with poor morphological characteristics (yellow and small leaves). Furthermore, we treated plants with 0.8 mM (control) and ...
