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 ... -
Electroanalysis of Organo-Chalcogenic Perovskite Nanomaterials
(University of the Western Cape, 2017)Organometallic halide perovskite solar cells have developed as one of the most promising contenders for the production of solar cells. The generic perovskite (PS) structure ABX3 allows manufacturing a broad range of PS ... -
Enabling the production of black soldier fly larval protein from lignocellulosic biomass through pre-treatment and enzymatic hydrolyse
(University of the Western Cape, 2023)Due to the rapid increase in the world’s population, alternative food resources are crucial to sustain the human diet. Insects can produce valuable proteins and nutrients that can be used as high-quality animal feedstuff ... -
Engineering bacterial magnetic nanoparticles
(University of the Western Cape, 2013)Magnetosomes, produced by magnetotactic bacteria (MTB), are the most attractive alternative source of non-toxic biocompatible magnetic nanoparticles (MNPs). A magnetosome contains Fe2O4 magnetite with properties superior ... -
Engineering homoaromatic substrate specificity into aliphatic-specific Geobacillus pallidus RAPc8 nitrile hydratase
(University of the Western Cape, 2007)Geobacillus pallidus RAPc8 is a thermophilic nitrile-degrading isolate, obtained from thermal sediment samples of a New Zealand hot spring. The G. pallidus RAPc8 NHase gene has been cloned and expressed in E. coli. The ... -
Eukaryotic diversity of miers valley hypoliths
(University of the Western Cape, 2012)The extreme conditions of Antarctic desert soils render this environment selective towards a diverse range of psychrotrophic microbial communities. Cracks and fissures in translucent quartz rocks permit an adequate amount ... -
Evaluating the specancer cell targeting peptides for applications in cancer diagnostics
(University of the Western Cape, 2013)Cancer is a disease most often associated with poor prognosis. During the development of the disease, cells acquire genetic mutations which result in changes in bio-molecules (DNA and protein), thus altering normal ... -
Evaluation of agronomic and drought response traits in two cultivars of soybean for cultivation in the Transkei region of the Eastern Cape
(University of Western Cape, 2020)Drought is a major stress that affects the productivity of plants across the globe. The consequences of drought are posed to continue reducing agricultural productivity as world climate changes. This makes it imperative ... -
Evaluation of cytotoxic activity of gold nanoparticles naturally synthesised from South African indigenous medicinal plant extracts
(University of the Western Cape, 2018)Nanotechnology has emerged as a promising field in the quest to address health conditions. Green nanotechnology is a fairly new branch of nanotechnology, which aims to produce and utilize nanomaterials in a way that is ... -
Evaluation of insertion-deletion polymorphisms with the kit Qiagen Investigator® DIPplex for forensic application in South Africa
(University of the Western Cape, 2015)Insertion-deletion polymorphisms (indels) have been underutilized in forensic identification of individuals in comparison with single nucleotide polymorphisms (SNPs) and short tandem repeat (STRs) systems. The use of ... -
Evaluation of the anticancer and molecular effects of green synthesized silver nanoparticles
(University of the Western Cape, 2023)Globally, cancer is considered the second leading cause of death with a staggering tally of 10 million deaths. Breast, lung, colon, rectum and prostate cancers are amongst the most commonly diagnosed cancers. The current ... -
The evaluation of Y-STR loci for use in forensics
(University of the Western Cape, 2005)The aim of this study was to investigate the forensic usefulness of various Y-chromosome short tandem repeat loci among South African sub-populations. Three different sets of Y-chromosome short tandem repeat loci were ... -
Exogenous caffeic acid alters molecular responses in Salvia hispanica L.
(University of the Western Cape, 2016)Salt stress is one of the most important abiotic stresses, resulting in the accumulation of ROS, which amount to great agricultural losses by influencing plant yield and in turn threaten sustainable agriculture and food ... -
Exogenous carbon monoxide and jasmonic acid mitigate salt stress in Sorghum bicolor
(University of the Western Cape, 2022)The agricultural sector plays an important role in the world economy. Expanding research is piloting its improved contribution to the economic sector. Despite the economic gain, the increasing population has already put ... -
Exploring anti-tyrosinase bioactive compounds from the Cape flora
(University of the Western Cape, 2018)Tyrosinase is an enzyme widely distributed in the biosphere and is found in many species of bacteria, fungi, animals, and plants; it is associated with melanin production. Even though it possesses many beneficial properties ... -
