Short CV

Norman Muzhinji obtained a BSc (hons) degree in Applied Biology in 2004, from the National University of Science and Technology in Zimbabwe with a specialization in molecular biology, genetics, biotechnology, virology and mycology. In 2007, he obtained a MSc degree in Biotechnology from the University of Zimbabwe with a focus on molecular biology, microbiology, and plant biotechnology. Immediately after finishing his MSc in Biotechnology, he was involved in tobacco research at Tobacco Research Board as a Molecular Biologist focusing on plant molecular pathology, breeding, diagnostics, tissue culture, plant-pathogen interaction. In 2016, he obtained his PhD in Plant Pathology from the University of Pretoria focusing on Rhizoctonia- Potato pathosystem, including various aspects such as occurrence and distribution of Rhizoctonia (https://doi.org/10.1094/PDIS-02-15-0236-RE), symptomatology (https://doi.org/10.1094/PDIS-08-13-0815-PDN), population genetics and evolution (https://doi.org/10.1016/j.funbio.2016.02.009), method of spread (https://doi.org/10.1094/PDIS-03-17-0329-RE), fungicide resistance monitoring (https://doi.org/10.1094/PDIS-09-17-1470-RE) and control. The research provided knowledge in the understanding of the distribution and biology of Rhizoctonia in South Africa and the knowledge is being used to optimize Rhizoctonia disease control management strategies.

After completing his PhD, he remained with the potato pathology group at University of Pretoria where his research focus was occurrence, epidemiology, understanding pathogen population genetics, plant-pathogen interaction, and molecular diagnostics. In one project ( https://doi.org/10.1094/PHYTO-12-18-0467-R ), he investigated the population biology and genetic variation of Spongospora subterranea f. sp. subterranea, the causal pathogen of powdery scab and root galls on potatoes in South Africa. Despite being one of the most important potato pathogens in South Africa, little information was available on the genetic structure and diversity of Sss, which could provide insight into the factors shaping its evolution and the role of inoculum sources in disease development. In another work ( https://doi.org/10.1111/ppa.13029 ), we used used RNA-seq to identify differentially expressed genes in tolerant and susceptible potato cultivars in response to Spongospora subterranea f. sp. subterranea infection. Understanding the molecular mechanisms of resistance has the potential for development of molecular markers for selection of powdery scab tolerant potato lines in marker assisted breeding programs. In another work, he developed a TaqMan qPCR technique for identification of Pectobacterium brasiliense (https://link.springer.com/article/10.1007/s10658-020-02097-4), the causal agent of soft rot and blackleg diseases on potato. The developed assay is useful for routine diagnostics, surveillance, and epidemiological studies.

From 2022, Norman held a position of a Senior Lecturer and programme coordinator for the BSc Horticulture programme at the Namibia University of Science and Technology.   Currently he is  employed as a Senior Lecturer in the Department of Plant Sciences, Division of Plant Pathology, of the University of Free State, South Africa.
