3,3' Diindolylmethane mediated signalling and its role in Brassica napus L. responses to vanadium
Gokul, Arun (University of the Western Cape, 2016)Anthropogenic activities such as mineral mining, improper watering practices, and the use of heavy metal contaminated fertilizers have caused an influx of heavy metals into arable lands. These heavy metals may have a ... -
3,3'-diindolylmethane improves drought tolerance of Zea mays through enhancing antioxidant activity
Basson, Gerhard Leroy (University of the Western Cape, 2018)Maize is one of the most abundantly produced cereals and contributes to about 40% of the global cereal production. This figure will have to increase in order to feed the ever-growing human population. One of the major ... -
Characterisation of a novel soybean candidate glutathione peroxidase/thioredoxin-dependent peroxidase in soybean exposed to osmotic/drought stress
Phillips, Kyle (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
Adams, Ruqaiyah (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 ... -
Comparative analysis of 3, 3'- diindolylmethane and indole-3-carbinol respective treatments in Brassica napus L.
Carelse, Mogamat Fahiem (University of the Western Cape, 2017)Lately, there has been serious contamination of soils and ground water caused by mineral mining and environmental pollution leading to heavy metal accumulation within soils and over time rendering the soil infertile. The ... -
Effects of exogenous myristic acid on growth and germination of Brassica napus L. under zirconium toxicity
Addinall, Riyaad (University of the Western Cape, 2016)Lipids when exogenously applied are known to cause various changes in ROS levels produced within plants. They can either be beneficial to the plant when not stimulating the overproduction of ROS thus resulting in improved ... -
Gallic acid modulates salt stress tolerance in soybean plants by regulating antioxidant capacity
Menzi, Pateka (University of the Western Cape, 2017)Soybean [Glycine max L (mer)] is one of the top commodity crops in the world including South Africa (de Beer and Prinsloo, 2013). These small yet important podded legumes are a great source of protein and are used in many forms. -
Identification and characterisation of potential virulence genes of Salmonella from rooibos tea
Johannes, Nashleen Shereen (University of the Western Cape, 2015)The aim of this study was to investigate the presence of Salmonella in the tea processing environment, to identify and detect potential virulence genes isolated from Salmonella in the tea, and to determine the antibiotic ... -
Identification and Molecular validation of Biomarkers for the accurate and sensitive diagnosis of bacterial and viral Pneumonia
Bakare, Olalekan Olanrewaju (University of Western Cape, 2019)Pneumonia remains the major cause of death in children and the elderly and several efforts have been intensified to reduce the rate of pneumonia infection. The major breakthrough has been the discovery of certain biomarkers ... -
Identification of candidate plant growth promoting endophytes from Echium plantagineum roots
Wu, Ruomou (University of the Western Cape, 2018)The yearly increase of global population will result in a greater demand for crop production, but with the climates changes and a lack of available agricultural land it will become increasingly more difficult to provide ... -
Identification of novel microRNAs as potential biomarkers for the early diagnosis of ovarian cancer using an in-silico approach
Zahra, Latib (University of the Western Cape, 2019)Ovarian cancer (OC) is the most fatal gynaecologic malignancy that is generally diagnosed in the advanced stages, resulting in a low survival rate of about 40%. This emphasizes the need to identify a biomarker that can ... -
Impact of vanadium stress on physiological and biochemical characteristics in heavy metal susceptible and tolerant Brassicaceae
Gokul, Arun (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 ... -
Isolation and characterisation of leaf endophytic bacteria from weed plants for enhancing salinity stress tolerance in Brassica napus
Ismail, Tashreeq (University of the Western Cape, 2020)In an ever changing environment, plants are constantly challenged by various abiotic stresses such as salinity, which limits global crop production. This directly affects food availability for the global population, which ... -
Isolation and characterization of bacterial endophytes for growth promotion of Phaseolus vulgaris under salinity stress
Thompson, Biosha (University of the Western Cape, 2020)As the global human population grows, so does the demand for faster food production rates. Owing to this, agricultural practices have had to expand and move into semi-arid and arid regions, too, where frequent irrigation ... -
Isolation and characterization of plant growth promoting endophytic bacteria from Eriocephalus africanus roots]
Mia, Junaid (University of the Western Cape, 2018)Endophytic bacteria are known to have an endosymbiotic relationship with plants and provide them with many beneficial properties. These bacteria stimulate plant hormones, provide protection from pathogens and increase ... -
Isolation and characterization of plant growth promoting endophytic bacteria from Medicago lupulina for enhanced drought tolerance in Maize
Istain, Brandon (University of the Western Cape, 2019)Maize is one of the major staple foods in many African nations however, this crop is sensitive to environmental stressors. Drought is a major environmental stressor affecting maize production. Due to global warming, drought ... -
Isolation and characterization of stem endophytic bacteria from weed plants for enhancing Vanadium tolerance in Brassica napus
Siebritz, Alex (University of the Western Cape, 2019)Bacterial endophytes are able to improve the growth of their hosts through a number of different mechanisms such as nutrient uptake regulation, plant hormone production and regulation, siderophore production and phosphate ... -
Methylgyoxal signalling in Phaseolus vulgaris under phosphate deficiency
Gcanga, Esihle (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 ... -
