Diversity of Frankia associated with Morella species of the Cape floristic region of Southern Africa
(University of the Western Cape, 2016)Frankia is one of two partners in the globally distributed N2-fixing actinorhizal symbiosis between this filamentous soil-dwelling actinomycete and almost 300 species of host plants from eight diverse angiosperm families. ... -
The diversity of key anabolic genes in antarctic hypolithons
(2009)Antarctica is known for its pristine environments. A variety of unsuitable environmental conditions were once thought to render the continent unsuitable for sustaining life. However, metagenomic data have revealed a wealth ... -
DNA metabarcoding for the identification of species within vegetarian food samples
(University of the Western Cape, 2021)Aims DNA metabarcoding has recently emerged as a valuable supplementary tool to ensure food authenticity within the global food market. However, it is widely known that highly processed food samples are one of DNA ... -
