(1978)No abstract available. -
The development of a white clover for use in the eastern high potential areas of South Africa.
(1988)The problems associated with the use of white clover in pastures in the eastern high potential areas of South Africa i.e. high P requirements, low tolerance to high Al levels and low pH in the soil as well as a limited ... -
Breeding for disease resistance to the major foliar pathogens of dry beans (Phaseolus vulgaris) in South Africa.
(1994)Resistances to bean common mosaic virus, halo, common and Ascochyta blight, angular leaf spot, anthracnose and rust pathogens of beans in South Africa were combined by reverse dichotomous crossing. Full resistance to ... -
The transformation of South African soya bean cultivars with a synthetic Basta resistance gene.
(1995)The development of a genetic engineering system for soya bean (Glycine max L.) is described in this thesis. Routine tissue culture regeneration systems were developed for South African cultivars of soya bean despite the ... -
An investigation into the heritability of commercially important traits in a sugarcane population under dryland conditions.
(1995)Inheritance studies have previously been undertaken at the South African Sugar Association Experiment Station (SASEX) under irrigated conditions. Since most sugarcane is grown in South Africa under dryland (raingrown) ... -
Direct transformation of maize (Zea mays L.) tissue using electroporation and particle bombardment, and regeneration of plantlets.
(1996)Please open electronic version for Abstract. -
Optimisation of the randomly amplified polymorphic DNA (RAPD) technique for the characterisation of selected South African maize (Zea mays L.) breeding material.
(2000)Maize (Zea mays L.) is an important agronomic crop with the maize industry forming an important component of the South African economy. Considerable effort has been directed towards the genetic improvement of maize through ... -
Near infrared analysis of sugarcane (Saccharum spp hybrid) bud scales to predict resistance to Eldana stalk borer (Eldana saccharina Walker).
(2003)The eldana stalk borer (Eldana saccharina Walker) is the most serious pest of the Southern African sugarcane industry, and it is imperative that effective control measures are available to minimize economic damage. Because ... -
Cloning, expression and purification of the immunity factor associated with leucocin A production.
(2004)Leucocin A is a bacteriocin produced by Leucoconostoc gelidium UAL 187-22. Bacteriocin producer strains possess an immunity protein, which enables the strain to protect itself against its own bacteriocin. The immunity ... -
Characterization of streptococcal infections in KwaZulu-Natal Durban by random amplified polymorphic DNA anaylsis and DNA macrorestriction analysis.
(2004)A collection of 29 clinical streptococcal isolates obtained from the University of KwaZulu-Natal, Medical School, Durban Metro area (South Africa) were studied to establish their penicillin G susceptibility patterns often ... -
Investigation of leptin genotypes and economically important dairy traits in jersey cows.
(2005)Dairy farming is one of the most important agricultural industries in South Africa, and thus improving the performance of dairy cows, with respect to economically important dairy traits, would be beneficial. Selection ... -
Individual identification and parentage analysis of Struthio camelus (ostrich) using microsatellite markers.
(2005)Ostrich (Struthio camelus) breeding is a well-developed industry in South Africa. However, successful genetic management has yet to be implemented. Parentage in colony breeding ostriches is unknown, where for a given ... -
Fingerprinting of full and half-sib black wattle (Acacia mearnsii) progenies using Random Amplified Polymorphic DNA (RAPD).
(2005)Black wattle (Acacia mearnsii), which belongs to the genus Acacia, is one of the many species of trees or hardwoods grown commercially in South Africa. Black wattle is a species indigenous to Australia and was introduced ... -
Characterisation of antibiotic resistance in Streptococcus, Enterococcus and Staphylococcus using a bioinformatics approach.
(2005)The rate at which bacterial pathogens are becoming resistant to antibiotics is quite alarming, and therefore much attention has been focussed on this area. The mechanism whereby the bacterial cells acquire resistance is ... -
Characterization of the autolytic systems in selected streptococcal species.
(2005)Autolysins are endogenous enzymes responsible for the cleavage of specific bonds in the bacterial sacculus resulting in damage to the integrity and protective properties of the cell wall. The true biological functions of ... -
The elucidation of the possible mechanism of vancomycin-resistance in selected streptococcal and enterococcal species.
(2005)Three Streptococcal strains: S. milleri P213, S. milleri P35 and S. milleri B200 and three enterococcal strains: E. faecalis 123, E. faecalis 126 and E. faecium were used to test for vancomycin resistance. Two strains were ... -
Investigation of the utilization of microsatellites for fingerprinting in three endangered southern African crane species.
(2006)Cranes are large elegant birds that occur on all continents of the world except for South America and Antarctica. Of the fifteen species of crane worldwide, three predominantly occur in southern Africa; the Wattled crane ... -
Computer simulation of marker-assisted selection utilizing linkage disequilibrium.
(2006)The face of animal breeding has changed significantly over the past few decades. Traditionally, the genetic improvement of both plant and animal species focussed on the selective breeding of individuals with superior ... -
Identification and remediation of student difficulties with quantitative genetics.
(2006)Genetics has been identified as a subject area which many students find difficult to comprehend. The researcher, who is also a lecturer at the University of KwaZulu-Natal, had noted over a number of years that students ... -
Autolytic characterization of selected Enterococcal strains, (previously Streptococcal)
(2007)Autolysins are enzymes that cleave specific structural components within the bacterial cell wall. They contribute to numerous cellular activities such as cell growth, cell division, peptidoglycan recycling and turnover. ...
