Modulation of soybean and maize antioxidant activities by Caffeic acid and nitric oxide under salt stress
(University of the Western Cape, 2012)This study explores the roles of exogenously applied nitric oxide, exogenously applied caffeic acid and salt stress on the ontioxidant system in cereal (exemplified by maize) and legume (using soybean as an example) plants ... -
Modulation of soybean and maize antioxidant activities by caffeic acid and nitric oxide under salt stress

Molecular analysis of red colouration in 'Bon Rouge' pear (Pyrus communis L.)
(University of the Western Cape, 2018)The 'Bon Rouge' pear cultivar was developed from a bud mutation on a 'Bon Chretien' pear tree. The latter is characterised by green fruit skin and leaves, while 'Bon Rouge' is characterised by red leaves and red fruit skin ... -
The molecular characterisation of a baculovirus isolated from trichoplusia ni
(University of the Western Cape, 2001)In South Africa there are more than 106 insects pests which attack a wide variety of crops. The top ten or twenty of these can seriously limit successful production on the farm. Costs involved in controlling these pests ... -
Molecular Characterisation of the Brassinosteroid, Phytosulfokine and cGMP-dependent Responses in Arabidopsis thaliana
(University of the Western Cape, 2010)In this thesis, we have firstly cloned and expressed the domains that harbours the putative catalytic GC domain in these receptor molecules and demonstrate that these molecules can convert GTP to cGMP in vitro. Secondly, ... -
Molecular characterization of Campylobacter isolates from free range and commercial chicken in South Africa
(University of the Western Cape, 2012)Campylobacter species are the most common bacteria associated with acute diarrhoea and is responsible for 400 to 500 million reported cases globally. It is not uncommon for 35% to 85% of chicken flocks to be infected with ... -
The molecular characterization of trichoplusia ni single nucleocapsid nucleopolyhedrovirus: a study on early regulatory features
(University of the Western Cape, 2003)With the development of biological insecticides, many research efforts have been made in baculoviruses to investigate fundamental molecular aspects of these viruses, such as the function and regulation of genes, genome ... -
Molecular detection and characterisation of RNA viruses of honeybees
(University of the Western Cape, 2009)Propagation methods for honeybee viruses have not changed since these viruses were discovered. There are no suitable cell lines or cell culture techniques available for honeybee viruses. Honeybee viruses have to be manually ... -
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 ... -
Molecular detection and genetic manipulation of the Black Queen Cell Virus
(University of the Western Cape, 2002)The South African isolate of the Black Queen-Cell Virus (BQCV), a honeybee virus, was previously found to have an 8550 nucleotide genome excluding the poly(A) tail. Its genome contained two ORFs, a 5'-proximal ORF encoding ... -
Molecular detection and study of Campylobacter and related microorganisms
(University of the Western Cape, 2010)Species of Campylobacter, Arcobacter and Helicobacter have been associated with various diseases in humans and animals; and chickens have been identified as a reservoir of these microorganisms. Two published techniques and ... -
Molecular dynamic simulation studies of the South African HIV-1 Integrase subtype C protein to understand the structural impact of naturally occurring polymorphisms
(University of the Western Cape, 2021)The viral Integrase (IN) protein is an essential enzyme of all known retroviruses, including HIV-1. It is responsible for the insertion of viral DNA into the human genome. It is known that HIV-1 is highly diverse with a ... -

The molecular evolution and epidemiology of Rubella virus
(University of the Western Cape, 2014)Despite widespread rubella virus (RV) vaccination programs, annually RV still causes severe congenital defects in an estimated 100,000 children globally. A concerted attempt to eradicate RV is currently underway and ... -
Molecular genetics: strategies to identify congenital cataract genes in captive-bred vervet monkeys
(University of the Western Cape, 2013)Molecular genetics: strategies to indentify congenital cataract genes in captive-bred Vervet monkeys Zandisiwe Emilia Magwebu MSc thesis, Department of Medical Biosciences, University of the Western Cape The present ... -
Molecular genetics: strategies to identify congenital cataract genes in captive-bred Vervet monkeys
(University of the Western Cape, 2012)The present study describes molecular aspects of inherited congenital cataract in captive-bred Vervet monkeys. Congenital cataracts are lens opacities that are present at birth or soon after birth and include hereditary ... -
A molecular investigation of the prevalence of suspected periodontopathogens and their association with preterm birth
(University of the Western Cape, 2010)More than 20 million infants in the world (15.5 % of all births) are born with low birth weight. Ninety-five % of them are in developing countries. Oral colonization of Gramnegative anaerobes has been implicated as a risk ... -

Molecular modeling and simulation studies to prioritize sequence variants identified by whole-exome sequencing in a South African family with Parkinson's disease
(University of Western Cape, 2021)Parkinson’s disease (PD) is a neurodegenerative disorder that occurs due to a loss of dopaminergic neurons in the substantia nigra. It is one of the most common neurodegenerative disorders, ranking second only to Alzheimer’s ...
