The Department of Science and Technology has extended two of the National Research Foundation’s SARChI research chairs at the University of the Free State (UFS). 

The Research Chair in Diseases and Quality of Field Crops, together with the Research Chair in Vector-borne and Zoonotic Pathogens, have both been extended for another five years. 

Prof Maryke Labuschagne, currently Professor of Plant Breeding in the Department of Plant Sciences, is leading the chair on Diseases and Quality of Field Crops.

The Chair on Vector-borne and Zoonotic Pathogens is headed by Prof Felicity Burt from the Division of Virology in the Faculty of Health Sciences.

Prof Corli Witthuhn, Vice-Rector: Research, says it was the hard work and commitment of Profs Labuschagne and Burt that resulted in the extension of the SARChI research chairs. “They have excelled in terms of student supervision and publications in high-impact international journals.  They also serve as mentors for young academics, postdoctoral fellows, and colleagues through their passion for their different fields of interest.”

Prof Witthuhn believes that this extension of the two SARChI chairs speaks of the progress that the UFS has made in terms of developing itself as a research-led university. “We are proud of the two senior academics for their supervision, mentorship, and leadership and their contribution to building our reputation,” she says. 

Diseases and Quality of Field Crops

The focus of the research chair in Diseases and Quality of Field Crops is on advancing food security and nutrition in Africa and contributing to poverty reduction and achieving sustainability goals. 

Prof Labuschagne says despite recent advances, the headlines regarding hunger and food security remain alarming: one in nine people on earth will go to bed hungry every night. Globally, 800 million people do not have enough to eat to be healthy, and a third of all deaths among children under five in developing countries are linked to undernourishment. 

She believes the uniqueness and strength of the research chair lies in a two-pronged approach, namely the breeding of cereal crops for resistance to fungal diseases, and improving the quality of crops for processing and consumption, thus making an impact on food security in South Africa and the rest of Africa through this collaborative effort. 

She is confident that the extension of the research chair will allow them to continue and to expand their research, “which has built up a lot of momentum”.

Besides the 12 PhD and 8 MSc degrees they delivered in the first five years, they also contributed significant research outputs and cultivar releases. She adds that they would like to expand on the significant international collaboration they have established. 

Vector-borne and Zoonotic Pathogens

According to Prof Burt, the SARChI chair in Vector-borne and Zoonotic Pathogens builds on existing research strengths at the UFS and aims to contribute towards identifying and investigating medically significant arboviruses and zoonotic viruses in the country.
 
“To date, the research chair has facilitated progress towards establishing serosurveillance studies for various vector-borne viruses, specifically Crimean-Congo haemorrhagic fever virus, a tick-borne and zoonotic virus that causes severe disease with fatalities.”

The team of researchers operating within this research chair is currently also performing studies to determine the seroprevalence of severe acute respiratory coronavirus 2 (SARS-CoV-2) in the Free State.

Prof Burt has always taken the importance of community engagement into account, and with the current pandemic, she believes that it is now more important than ever to increase public awareness of zoonotic diseases.

She emphasises that the majority of new and emerging viruses are zoonotic in origin and that the current SARS-CoV-2 pandemic highlights the impact of an emerging zoonotic pathogen on society. Therefore, she feels that it is important to build capacity in this field and to focus research efforts on identifying and understanding where these pathogens cycle in nature, the potential for spill-over to humans, and what the drivers are for the emergence of these pathogens.

Prof Burt trusts that the renewal of the research chair will allow them to take advantage of the new biosafety laboratory that the UFS has invested in. “This will permit us to research pathogens that were previously excluded from our programme due to biosafety considerations.  The chair will furthermore contribute towards enhancing, strengthening, and developing research and knowledge in the field of epidemiology and pathogenesis of vector-borne and zoonotic viruses,” she says.

Plant eco-physiologist finds effective solutions for crop optimisation

on a crop.

In a time characterised by society facing increasing population growth, food crises, and extreme climatic conditions such as drought, it is essential for farmers to integrate science with their work practices in order to optimise crops.

Role of photosynthesis and plant sap data

By knowing how to use photosynthesis and plant sap data for determining plant health, fast and effective solutions could be established for the optimisation of crops. This technique, which could help farmers utilise every bit of usable land effectively, is the focus of Marguerite Westcott’s PhD study. She is a junior lecturer and plant eco-physiologist in die Department of Plant Sciences at the University of the Free State.

Westcott uses this technique in her studies to prove that a newly-developed bio-stimulant stimulates plants in order to metabolise water and other nutrients better, yielding increased crops as a result.

Agricultural and mining sectors benefit from research

The greatest part of these projects focuses on the agricultural sector. Westcott and a colleague, Dr Gert Marais, are researching the physiology of pecan and citrus trees in order to optimise the growth of these crops, thus minimising disease through biological methods. Field trials are being conducted in actively-producing orchards in the Hartswater and Patensie areas in conjunction with the South African Pecan Nut Producers Association (SAPPA) amongst others.
 
The principles that Westcott applies in her research are also used in combination with the bio-stimulant in other studies on disturbed soil, such as mine-dump material, for establishing plants in areas where they would not grow normally. This is an economical way for both the agricultural and mining sectors to improve nutrient absorption, stimulate growth, and contribute to the sustainable utilisation of the soil.

The bio-stimulant contributes to the immunity of the plants.
It was tested in these pecan nut orchards (Hartswater).

Soil rehabilitation key aspect in research projects

“One of two things is happening in my research projects. Either the soil is rehabilitated to bring about the optimal growth of a plant, or the plants are used to rehabilitate the soil,” says Westcott.

Data surveys for her PhD studies began in 2015. “This will be a long-term project in which seasonal data will be collected continuously. The first set of complete field data, together with pot trial data, will be completed after the current crop harvest,” says Westcott.
