(Stellenbosch : Stellenbosch University, 2020-04)ENGLISH ABSTRACT: Schizophrenia is a debilitating neuropsychiatric disorder affecting approximately 1% of the global population. Unfortunately, antipsychotic treatment is ineffective in 50% of patients. The complex, ... -
Investigating the role of miRNA-mediated regulation in antipsychotic treatment response in a South African first-episode schizophrenia cohort
(Stellenbosch : Stellenbosch Univerity, 2020-04)ENGLISH ABSTRACT: Although considerable advances in genomics research, with the likes of Genome-Wide Association Studies (GWAS), have uncovered vast quantities of genomic data regarding the genetic basis of many neuropsychiatric ... -
Enhancing drought and osmotic stress tolerance by overexpressing α-acetolactate decarboxylase and acetoin 2,3-butanediol dehydrogenase in planta
(Stellenbosch : Stellenbosch University, 2020-04)ENGLISH ABSTRACT: The effect of certain rhizosphere colonising bacteria on plant growth has been extensively exploited in agriculture since the green revolution of 1950. The bacteria symbiotically colonise the rhizosphere, ... -
Genetic and phenotypic characterisation of commercial dusky kob (Argyrosomus japonicus) cohorts
(Stellenbosch : Stellenbosch University, 2020-04)ENGLISH ABSTRACT: Argyrosomus japonicus (dusky kob) is a large sciaenid finfish indigenous to South Africa, and as an emerging aquaculture species, current production practices rely on mass spawning of wild progenitors to ... -
Analysis of the relationship between glycogen turnover and cell size in Escherichia coli
(Stellenbosch : Stellenbosch University, 2020-04)ENGLISH ABSTRACT: Glycogen represents an important carbon energy store in organisms across all domains of life. Under permissible conditions, excess environmental glucose is incorporated into glycogen by the Gram-negative ... -
Species identification, lifestyles and mitogenomics of the elusive wasp assemblage associated with wild and cultivated olives in the Western Cape
(Stellenbosch : Stellenbosch University, 2019-12)ENGLISH ABSTRACT: While the international olive industry is greatly affected by the olive fruit fly (Bactrocera oleae), South African commercial crops are marginally affected. The rich assemblage of native parasitoid wasps ... -
Development of alternative diagnostic protocols for Candidatus Phytoplasma asteris and Coniella granati Sacc. (Syn. Pilidiella granati)
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: The Republic of South Africa (RSA) is an integral part of the global fruit exporting chain. Currently, South Africa is ranked eighth in the world in wine production, exporting 40% of all locally produced ... -
Species delineation in the southern African endemic catshark genus Haploblepharus
(Stellenbosch : Stellenbosch University, 2018-11)ENGLISH ABSTRACT: Accurate species identification is paramount for the effective implementation of conservation and management plans. Species identification in the genus Haploblepharus has historically been problematic due ... -
Identification and biochemical characterisation of an aryl β-glucosidase isolated from a cellulose-acetate rich environment via a functional metagenomic approach
(Stellenbosch : Stellenbosch University, 2018-11)ENGLISH ABSTRACT: Functional metagenomics has established itself as an indispensable tool in the search for novel genes by accessing the genetic information of previously unculturable microbes. These novel genes are ... -
Overexpression of a tomato SlNAC2 gene in Nicotiana tabacum to determine its potential role in enhancing drought tolerance in plants
(Stellenbosch : Stellenbosch University, 2018-12)ENGLISH ABSTRACT: The ability of transcription factors to regulate stress-response gene expression within a plant makes them ideal targets as transgenes for improving stress tolerance. The NAC (NAM/ATAF/CUC) transcription ... -
Mitochondrial genome assembly and population genetics of the common smoothhound shark, Mustelus mustelus
(Stellenbosch : Stellenbosch University, 2018-11)ENGLISH ABSTRACT: Knowledge of evolutionary history and population genetic structuring in economically important marine species are integral factors for a more comprehensive fisheries management approach in order to ... -
Initiation of a pre-breeding effort for water stress resistance traits and yield improvement in wheat
(Stellenbosch : Stellenbosch University, 2018-12)ENGLISH ABSTRACT: Wheat (Triticum aestivum L.) is an important crop produced in South Africa and across the world. Water stress and rust diseases (Puccinia spp.) are common factors hindering wheat growth and development. ... -
Functional identification of a putative stachyose synthase (StaS, Medtr7g106910.1) from Medicago truncatula, by overexpression in the Arabidopsis stachyose deficient double mutant atrs4/atrs5
(Stellenbosch : Stellenbosch University, 2018-11)ENGLISH ABSTRACT: The Raffinose Family Oligosaccharides (RFOs; Suc-Galn, 13 < n ≥ 1) are α1,6- galactosyl extensions of sucrose occurring exclusively in the plant kingdom and some photoautotrophic bacteria. This unique ... -
Analysis of aspects of the starch metabolic pathway in lower plants
(Stellenbosch : Stellenbosch University, 2018-12)ENGLISH ABSTRACT: Starch is an important plant storage polysaccharide that has been demonstrated to have a major influence on plant growth. Transitory starch is synthesized in the leaves of plants during the day as a ... -
Comparing different siRNA delivery systems to target Diuraphis noxia
(Stellenbosch : Stellenbosch University, 2018-12)ENGLISH ABSTRACT: Diuraphis noxia, also known as the Russian wheat aphid, is a major pest of wheat. Breeding for resistance against D. noxia has been relatively successful in wheat as there has been many resistance genes ... -
Initiation of a wheat pre-breeding effort aimed at yield improvement using male-sterility marker assisted recurrent selection
(Stellenbosch : Stellenbosch University, 2018-12)ENGLISH ABSTRACT: Continous decline in South Africa’s wheat production over the past few decades has lead to a corresponding rise in reliance on wheat imports to satisfy the local consumption needs. Wheat breeders need ... -
