Regulation of maize Ac/Ds transposition by replication and DNA methylation
… and DNA methylation in the dicot species Petunia hybrida was studied. Ds reporter vectors harboring TYLCV (Tomato Yellow Leaf Curl Virus) geminivirus replicon sequences and replicating in transfected petunia cells were constructed. It has been shown that the transposition of a Ds element …

Pollinator behaviour and the evolutionary genetics of petal surface texture in the Solanaceae
… species have lost conical petal cells. Using Petunia flowers to test bee preferences under conditions of motion, we investigate whether the tactile advantage of conical petal cells on complicated flowers can also benefit simple flowers with low inherent tactile difficulty. We find that flower …

Agrobacterium-mediated gene transfer into kiwifruit
… of these chimaeric GUS genes in transformed petunia leaf discs. GUS expression was detectable 2 days after inoculation, peaked at 3 – 4 days and then declined; if selection was imposed expression increased again after 10 - 14 days. The amount of expression observed 4 days after inoculation …

Elucidating the molecular basis of dihydroxyacetone (DHA) production in Leptospermum nectar
… expression in transgenic lines of Petunia and Nicotiana, showing elements essential for Sgpp2 expression are within that region. However, the promoter in 13 DHA producing L. scoparium genotypes was found to be similar, indicating variation in nectar DHA amounts may be conferred by …

Understanding the protein complexes involved in the reception of the plant hormone Strigolactone
… the development of branching in plants. In petunia, SL is perceived by its receptor, DAD2, an α/β hydrolase fold protein. This receptor also functions as a slow enzyme that hydrolyses SL into two non-active by-products. The hydrolytic function of the receptor is essential for SL signalling …

Development and validation of childhood trauma and exposure to violence intervention for African children in rural Limpopo Province
Childhood trauma and exposure to violence remain pressing global concerns, particularly in low-resource settings where access to mental health services is limited. In South Africa’s rural regions, children are disproportionately affected by domestic violence, abuse, and community violence, yet …

Macromolecular organization of flavonoid biosynthesis in Arabidopsis thaliana
… in A. thaliana as they are in maize and petunia. I also describe a novel method to clone fragments of DNA without ligase using the polymerase chain reaction (PCR). To establish an experimental model I have used a variety of techniques to analyze interactions between enzymes in the …

Assessing the microbial community structure’s diversity associated with nutrients concentration in the natural wetland systems
Microbial communities play a major role in natural wetlands systems biogeochemical cycles. Therefore, understanding the association between their composition, diversity and environmental parameters is significant in order to understand soil microbial ecology associated with nutrients concentration. …

Digital readiness and the adoption of self-service banking technologies in South Africa
Digital technologies are rapidly transforming banking; in turn, this has changing customers’ choices and preferences for interacting with banks. Digital banking channels have somewhat become a double-edged sword for the banking industry in that, on the one hand, they enhance customer convenience …
