Deciphering the determinants of molecular physiological responses to drought and heat stress in sorghum lines contrasting in stress tolerance via a proteomics approach
(University of the Western Cape, 2022)Sorghum is an important crop in Sub-Saharan Africa and South Asia. The predicted rise in global temperatures will increase the probability of exposing sorghum to heat waves in combination with drought. Thus, production ... -
In vitro evaluation of Leonotis leonurus to validate its potential as an alternative anti-diabetic drug
(University of the Western Cape, 2022)Africa is a rich source of medicinal plants with South Africa being known as a country with a strong history of traditional healing, which masses a variety of approximately 30 000 flowering plants and accounting for ... -
Biocontrol potential of fungal endophytes against Fusarium proliferatum in maize
(University of the Western Cape, 2022)Fusarium proliferatum is a fungal pathogen that is the cause of numerous diseases in various crops of fruit and vegetables. About 25% of the maize crops harvested annually are affected by mycotoxins produced by F. ... -
Influence of a selected endophyte consortium on salinity responses in Medicago sativa
(University of Western Cape, 2022)Salinity is one of the major limiting factors to crop production, which consequently contributes to the risk of reduced food security. Among other factors, food security depends on availability of sufficient and nutritious ... -
DNA metabarcoding for the identification of species within vegetarian food samples
(University of the Western Cape, 2021)Aims DNA metabarcoding has recently emerged as a valuable supplementary tool to ensure food authenticity within the global food market. However, it is widely known that highly processed food samples are one of DNA ... -
Comparison of multi-gene integration strategies in CRISPR-based transformation of Saccharomyces cerevisiae
(University of the Western Cape, 2021)Saccharomyces cerevisiae is an important host in industrial biotechnology. This yeast is the host of choice for the first and second-generation biofuels for ethanol production. Genome modification in S. cerevisiae has been ... -
Screening of marine bacteria as a source of bioactive secondary metabolites
(University of Western Cape, 2021)Marine invertebrate associated (MIA) bacteria are an important source of bioactive secondary metabolites with the potential to address the current anti-microbial resistance crisis experienced globally. Secondary metabolites ... -

Molecular detection and characterisation of RNA viruses of honeybees
(University of the Western Cape, 2009)Honeybees have evolved through the centuries to inhabit most parts of the world except for the extreme Polar Regions. These insects have also been susceptible to pathogens and disease which has always been part of the ... -
A proteomic analysis of drought and salt stress responsive proteins of different sorghum varieties
(University of the Western Cape, 2009)Sorghum (Sorghum bicolorï, a drought tolerant cereal crop, is not only an important food source in the semi arid/arid regions but also a potential model for studying and gaining a better understanding of the molecular ... -
Analysis of ammonia-oxidizing bacteria associated with the roots of Proteaceae plant species in soils of Fynbos ecosystem
(University of the Western Cape, 2005)Molecular methods were used to investigate the microbial diversity and community structure of ammonia-oxidizing bacteria (AOB) associated with the roots of the Proteaceae plant family. The identification of ammonia ... -
Microbiology of fly ash-acid mine drainage co-disposal processes
(University of the Western Cape, 2005)The waste products acid mine drainage (AMD), formed during coal mining and fly ash (FA) from coal burning power generation, pose substantial environmental and economic problems for South Africa. Eskom has developed a ... -
Recombinant expression of the pRb- and p53-interacting domains from the human RBBP6 protein for in vitro binding studies
(University of the Western Cape, 2004)This thesis describes the cloning and recombinant expression of domains from the human RBBP6 protein for future in vitro binding studies with pRb and p53. RBBP6 is a splicing-associated protein that is known to interact ... -
Structural characterisation of the interaction between RBBP6 and the multifunctional protein YB-l
(University of the Western Cape, 2010)Retinoblastoma binding protein 6 (RBBP6) is a 250 kDa RING finger-containing protein whose function is known to be mediated through interaction with other proteins. RBBP6 plays a role in the regulation of the tumour ... -
Laccases from actinomycetes for lignocellulose degradation
(University of the Western Cape, 2012)Lignocellulose has a complex structure composed mainly of lignin, hemicellulose and cellulose. Several enzymes are needed for the degradation of lignocellulose into simple sugars. Actinomycetes are known to produce laecases ... -
Identification and validation of putative therapeutic and diagnostic antimicrobial peptides against HIV: An in silico approach
(University of the Western Cape, 2013)Background: Despite the effort of scientific research on HIV therapies and to reduce the rate of HIV infection, AIDS still remains one of the major causes of death in the world and mostly in Sub-Saharan Africa. To date, ... -
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, ... -
The impact of different storage temperatures and storage period on the antioxidant activity of pomegranate
(University of Western Cape, 2021)Fruit storage at cold temperatures is normally used to delay decay while maintaining the fruit’s quality. However, storage at low temperatures for a prolonged period causes some important metabolic functions within the ... -
