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 ... -
Characterisation of AtPNP-A - a novel arabidopsis thaliana gene with role in water and salt homeostasis
(University of the Western Cape, 2009)Plant natriuretic peptides (PNPs) are a novel class of extracellular, systemically mobile molecules that elicit a number of plant responses important in homeostasis and growth. Natriuretic peptides were first identified ... -
Characterisation of eight non-codis Ministrs in four South African populations to aid the analysis of degraded DNA
(University of the Western Cape, 2009)In many forensic cases, such as mass disasters reconstruction cases, the recovered DNA is highly degraded. In such incidences, typing of STR loci has become one of the most powerful tools for retrieving information from ... -
Characterisation of microbial communities associated with hypolithic environments in Antarctic Dry Valley soils
(University of the Western Cape, 2008)The Eastern Antarctic Dry Valley region is a polar desert, where conditions of extreme aridity, high temperature fluctuations and high irradiation levels make it one of the most extreme environments on earth. Despite the ... -
Characterisation of N-terminal fragments of Retinoblastoma Binding Protein 6 for structural analysis
(University of the Western Cape, 2016)Retinoblastoma Binding Protein 6 (RBBP6) is a 200 kDa RING finger-containing protein that plays a role in 3'-end poly-adenylation of mRNA transcripts as well as acting as an E3 ubiquitin ligase against a number of proteins ... -
Characterisation of the endophytic bacterial communities associated with South African sorghum plants: looking for potential plant growth-promoting endophytes
(University of Western Cape, 2012)The term endophyte is used to define all microorganisms that, during a part of their life cycle, colonize the internal tissues of a plant host. Many endophytes have been found to promote plant growth by acting either as ... -
Characterization and engineering of Bacillus megaterium AS-35, for use in biodegradation of processed olive wastewater
(University of Western Cape, 2005)The popularization and health benefits associated with the "Mediterranean diet" saw a world wide increase in the production and consumption of processed olives and olive oil. During the brining of table olives large ... -
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 ATP-binding cassette drug transporters and their role in breast cancer treatment using in silico approach
(University of the Western Cape, 2019)Breast cancer is the most common cancer in women worldwide, and is the second most common cancer in the world, responsible for more than 500 000 deaths annually. Estimates are that 1 in 8 women will develop breast cancer ... -
Characterization of the role of a cycloartenol synthase gene (ZMCAS494) in Zea mays responses to drought stress
(University of the Western Cape, 2016)Plant Sterols are an important part of the membrane and their role is to control cell membrane fluidity and permeability. Several studies have indicated that plants that are mutant for genes that play a role in the sterol ... -
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 ... -
Characterization of the role of Zea mays burp domain-containing genes in maize drought responses
(University of the Western Cape, 2016)Global climate change has resulted in altered rainfall patterns, causing annual losses in maize crop yield due to water deficit stress. Therefore, it is important to produce maize cultivars which are more drought-tolerant. ... -
Characterization of two Arabidopsis thaliana genes with roles in plant homeostasis
(University of the Western Cape, 2004)Plants are continuously exposed to varying conditions in their environment, to which they have to adapt by manipulating various cellular processes. Environmental (abiotic) and pathogen (biotic) stress are challenges against ... -
Cloning and characterization of three compost metagenome-derived α‑L‑Arabinofuranosidases with differing thermal stabilities
(University of the Western Cape, 2014)Second generation biofuels production requires a suite of lignocellulolytic enzymes, acting synergistically to liberate the fermentable monosaccharides contained within agricultural waste materials. The use of thermostable ... -
Cloning, expression and characterisation of Amidase Genes from a psychrotolerant Nesterenkonia isolate
(University of the Western Cape, 2009)A nitrile and amide hydrolysing Nesterenkonia sp. was isolated from Antarctic soil and was characterised as a psychrotolerant, halotolerant and alkaliphilic extremophile. Amidases are widely distributed in both prokaryotic ... -
Cloning, expression and characterization of Novel Lipase and Esterases from Burkholderia multivorans UWC10
(2005)An esterase and lipase producing Burkholderia multivorans strain was isolated by culture enrichment strategies. A shotgun library of Burkholderia multivorans genomic DNA (prepared in E. coli/pUC18) was screened for lipase ... -
Comparative analysis of 3, 3'- diindolylmethane and indole-3-carbinol respective treatments in Brassica napus L.
(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 ... -
Comparative analysis of molecular and physiological responses of two canola genotypes to drought stress
(University of the Western Cape, 2016)Food security has always been one of the priority concerns in Africa, and it is mostly threatened by drought stress due to climate change. Drought-induced stress is one of the serious limiting factors of plant production, ... -
Comparative analysis of sorghum and other South African grains for sustainable bioethanol production
(University of the Western Cape, 2012)The depletion of oil reserves and the constant discharge of greenhouse gasses (GHG) that are associated with global warming have forced both political and scientific sectors to pursue alternative, renewable and sustainable ... -
