The nuclear 18S rDNA and chloroplast encoded rbcL gene sequences were used to investigate the evidence of residual UV-B induced mutagenesis in Dimorphotheca sinuata plants. The probes were generated by the polymerase chain ...

Harpagophytum is bitypic and native to Southern Africa. Its two species are Harpagophytum procumbens and H. zeyheri. H. procumbens is medicinal. A reliable method of identifying the species is through its fruit. However, ...

Allele frequencies for nine short tandem repeat (STR) loci from the AmpFlSTR® Profiler Plus PCR Amplification Kit were determined in five subpopulations across Botswana and tested for suitability for use in individual ...

Over the past few decades, there has been a depletion of the stratospheric ozone layer due to emissions of halogen-containing compounds of anthropogenic origin. This has resulted in a concomitant increase in solar ...

Residual long-term effects of increased UV-B radiation were investigated in an indigenous plant species, Dimorphotheca sinuata, by analysing photosynthetic gene expression. Reductions were observed in the amount of the ...

We used the Allin 2.0 GMO screening system from Biosmart, Switzerland to screen for the presence of genetically modified food sequences in maize meal samples, fresh fruit and vegetables from some retailers around Gaborone, ...

The present study on the Namaqualand daisy, Dimorphotheca sinuata sought to address two main questions: - first whether the natural populations show any evidence of variation in the chloroplast genome, and secondly if the ...
