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 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, ...
Structural characterisation of the interaction between RBBP6 and the multifunctional protein YB-1
(University of the Western Cape, 2010)
As a means of further localising the interaction, truncated fragments derived from the C-terminal region of YB-1, were tested for their interaction with the RING finger domain of RBBP6 using three different assays: a ...
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 ...
The C-economy, nutritional benefits and symbiotic performance of dual inoculated Phaseolus vulgaris (L.) plants, under variable nutrient conditions
(University of the Western Cape, 2010)
The tripartite symbiosis between Phaseolus vulgaris, arbuscular-mycorrhiza and the nodule bacteria, Rhizobia have been the focus of many studies ranging over a number of decades, however these studies have failed to answer ...
Respiratory and photosynthetic C and N metabolism of nodulated Lupin roots during phosphorus deficiency
(University of the Western Cape, 2010)
Growth of symbiotic legume hosts is P limited, because of the high energetic requirements associated with N2 fixation. Attempts to overcome P deficiency in soils where legumes are grown involve addition of P-based fertilisers. ...
