Genetic analysis of resistance to powdery mildew (podosphaeara leucotricha) in apple (Malus x dornestica Borkh.)
(University of the Western Cape, 2008)Apple powdery mildew, caused by Podosphaera leucotricha, is one of the major diseases of the cultivated apple in the Western Cape, causing severe losses in yield and affecting fruit quality. This affects the deciduous ... -
Genetic analysis of the Cape Sand Frog, Tomopterna delalandii (Tschudi 1838)
(University of the Western Cape, 2015)Tomopterna delalandii occurs throughout the west coast, Western Cape and south coast of South Africa. This range stretches across three distinct biogeographical assemblages. Based on historical records and the fact that ... -
Genetic and morphological comparisons within the orthopteran family Pneumoridae
(University of the Western Cape, 2019)Bladder grasshoppers belong to the order Orthoptera, ancient family Pneumoridae and Superfamily Pneumoroidea. This small group of grasshoppers are sound producing, nocturnal, herbivorous grasshoppers endemic to the coastal ... -
Genetic diversity of the Organic Cation Transporter 1 gene within the Cape Coloured Population
(University of the Western Cape, 2012)The aim of this study was to investigate the genetic diversity of the SLC22A1 gene and to deduce its possible pharmacogenetic implications within the Cape Coloured population of South Africa; a uniquely admixed population ... -
Genetic mapping of fruit quality traits in apple (malus x domestica borkh.)
(University of the Western Cape, 2011)Apple fruit quality is of utmost importance to apple farmers and breeders in the selection and commercialization of new cultivars. Fruit size, colour, texture, firmness and taste are all traits that affect the quality of ... -
Genetic variation among verticillium dahliae isolates using pathogenicity and aflp analysis
(University of the Western Cape, 1999)Soilborne plant pathogenic fungi have had an important economic and social impact on humans since the evolution of agricultural societies (Stakman, 1959). In South Africa, the soilborne pathogen Verticillium dahliae Kleb, ... -
Genetic variation between two subspecies of Reedfrogs in the genus Hyperolius (Anura: Hyperoliidae)
(University of the Western Cape, 1993)The frog genus Hyperolius is the largest of 19 genera in the Hyperoliidae (Channing, 1939). The members of the genus display considerable morphological homogeneity with a diversity of dorsal colour patterns. The genus is ... -
"Genetic variation between two subspecies of reedfrogs in the genus Hyperolius (Anura: Hyperoliidae)"
(University of the Western Cape, 1993)H. m. broadleyi and H. m. verrucosus are not only different in terms of colour pattern, but distinct genetic differences were detected in restriction site maps of their ribosomal DNA. A sequence divergence value of 13,8% ... -
Genetic variation of rana fuscigula in Southern Africa
(University of the Western Cape, 1994)Naturalists have long been engaged in describing and explaining diversity in the biological world. The discovery of the molecular basis of inheritance has led to rapid increase in the use of biological macromolecules in ... -
Genome assembly of next-generation sequencing data for the Oryx bacillus : species of the Mycobacterium tuberculosis complex
(University of the Western Cape, 2011)Next generation sequencing (NGS) technology platforms have accelerated ability to produce completed genome assemblies. Recently, collaborators at Tygerberg Medical School outsourced the sequencing of Oryx bacillus, a ... -
Genome-wide annotation of chemosensory and glutamate-gated receptors, and related genes in Glossina morsitans morsitans tsetse fly
(University of the Western Cape, 2014)Tsetse flies are the sole vectors of trypanosomes that cause nagana and sleeping sickness in animals and humans respectively in tropical Africa. Tsetse are unique: both sexes adults are exclusive blood-feeders, females are ... -
Genome-wide identification and comprehensive analysis of transcriptionsl desert regions
(University of the Western Cape, 2009)The initiation of transcription in mammalian genomes predominatly occurs at 5' promoter regions, however increasingly initiation events have been observed within introns, coding exons and 3' UTRs. Nevertheless there ... -
Genomic and proteomic analysis of drought tolerance in Sorghum (Sorghum bicolor (L.) Moench)
(University of the Western Cape, 2014)Drought is the most complex phenomenon that remained to be a potential and historic challenge to human welfare. It affects plant productivity by eliciting perturbations related to a pathway that controls a normal, ... -
Genomic and proteornic analysis of drought tolerance in sorghum
(University of the Western Cape, 2014)Drought is the most complex phenomenon that remained to be a potential and historic challenge to human welfare. It affects plant productivity by eliciting perturbations related to a pathway that controls a normal, functionally ... -
Genomic diversity and functional analysis of the solute carrier genes within indigenous African and Cape Admixed populations
(University of the Western Cape, 2016)Solute carrier transporters belonging to the major facilitator family of membrane transporter are increasingly being recognized as a possible mechanism to explain inter-individual variation in drug efficacy and response. ... -
Genomic epidemiology of Rift Valley fever in East Africa
(University of the Western Cape, 2023)Rift Valley fever (RVF) is a climate-driven zoonotic disease of significant importance to public and livestock health given its epidemic potential. The disease was first identified in 1930 in the great rift valley region ... -
Genomic instability in South African breast cancer patients
(2013)Breast cancer (BC) is one of the most common malignancies in women. Death results from treatment failure and metastatic disease. Thousands of lives might be saved if it was possible to detect and eliminate occult metastatic ... -
