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 ... -
Characterization of the role of single domain soybean cystatins in regulating drought responses in soybean
(University of the Western Cape, 2015)This study investigated the effects that drought stress imposed on the growth and development of soybean plants. Soybeans were initially observed at the whole-plant level in order to identify the physical changes that had ... -
Effects of nitric oxide and hydrogen peroxide on antioxidant enzyme activity in zea mays subjected to drought
(University of Western Cape, 2021)Agricultural practices are significantly affected by drought. Drought is one of the most important plant stresses, causing several physiological, morphological, biochemical, and molecular changes in plants. Drought stress ... -
Effects of nitric oxide on novel soybean cystatin gene expression under salt stress in soybean
(University of the Western Cape, 2012)Nitric oxide (NO) has been shown to orchestrate multiple defense responses to both abiotic and biotic stress. Importantly, elevation of nitric oxide content in plants by using nitric oxide generating compounds has been ... -
The effects of nitric oxide on soybean superoxide dismutase activity during osmotic stress
(University of the Western Cape, 2012)Nitric oxide (NO) is a signaling molecule involved in mediating plant responses to various biotic and abiotic stresses. Major abiotic stresses (drought, salinity, cold) induce common cellular responses, causing osmotic ... -
Evaluation of the capacity of hydrogen sulfide to reduce infection of maize
(University of the Western Cape, 2020)Maize (Zea mays L.) is grown globally as an important grain crop in South Africa, United States, China and Brazil and plays a major role in the worldwide economy. In South Africa, the grain is utilised for food consumption, ... -
Investigation of the link between drought-induced changes in the expression of a novel sterol biosynthesis gene and drought tolerance in soybean
(University of the Western Cape, 2017)Glycine max (soybean) is an important crop species globally as it is used as a protein-rich food and feed crop and as a source of oils used in the food and biofuel industry. However, the growth and yield of soybean is ... -
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 ... -
Modulation of soybean and maize antioxidant activities by Caffeic acid and nitric oxide under salt stress
(University of the Western Cape, 2012)This study explores the roles of exogenously applied nitric oxide, exogenously applied caffeic acid and salt stress on the ontioxidant system in cereal (exemplified by maize) and legume (using soybean as an example) plants ... -
Modulation of soybean and maize antioxidant activities by caffeic acid and nitric oxide under salt stress
(University of Western Cape, 2012) -
Physio-biochemical characterization of two wheat cultivars to Fusarium proliferatum infection
(University of the Western Cape, 2019)Wheat is a key global commodity in terms of acreage and tradeable value and as a staple in household diets. Many factors including biotic stress conditions have detrimental effects on global wheat production and yield. ... -
Physiological and molecular characterization of wheat cultivars to Fusarium oxysporum infection
(University of the Western Cape, 2019)Biotic stress is one of the main causes for agricultural loss of economically important cereal crops. The increasing prevalence of biotic stress inflicted by fungal species such as Fusarium has significantly reduced yields ... -
The role of p-coumaric acid on physiological and biochemical response of chia seedling under salt stress
(University of the Western Cape, 2020)The role of phenolic acids in mitigating salt stress tolerance have been well documented. However, there are contradicting reports on the effect of exogenously applied phenolic acids on the growth and development of various ...
