UFS celebrates excellence through its research hubs
The university considers its research chairs and the possibility of future chairs as an integral and strategic initiative to increase its national and international standing through excellent academic and research leadership.

The University of the Free State (UFS) is proud of its research leaders. As of 2018 the UFS has 156 NRF-rated researchers and five Sarchi Research Chairs. These chairs are designed to attract and retain excellence in research and innovation at South African public universities.

Getting the better of vector borne and zoonotic viruses

Prof Felicity Burt leads the Vector Borne and Zoonotic Virus Research Group in the Department of Medical Microbiology and Virology at the UFS. She was awarded a Research Chair to, among others, investigate medically significant vector-borne and zoonotic viruses currently circulating - mainly viruses transmitted by mosquitos and ticks, and viruses transmitted from animals to humans. 

“Years ago, no one knew what Ebola was. One outbreak later, backed by many media reports, and it is almost a household name. The same goes for the recent Zika virus outbreak in South America,” she explains the public’s interest and fears. To prevent the spread of vector-borne viruses to new areas, surveillance and awareness is important. Here in Bloemfontein, Prof Burt and her team are establishing surveillance programmes.

Why research on fungal infections?

“Many diseases no longer pose a threat to humans and life expectancy is prolonged. However, this has also caused an increase in various opportunistic infections, and most of all, fungal infections,” says Prof Carlien Pohl-Albertyn, who is heading the Research Chair for Pathogenic Yeasts in the Department of Microbial, Biochemical and Food Biotechnology. And the rise in resistance to antifungal treatments requires research into pathobiology, including new drug and treatment options. 

Activities of the Research Chair in Pathogenic Yeasts builds on existing research strengths and will contribute towards understanding pathobiology of medically significant pathogenic yeasts belonging to the genera Candida and Cryptococcus. 

Understanding higher education for more equality and justice

Prof Melanie Walker, from the Centre for Research on Higher Education and Development (CRHED) does research on higher education, inequalities and social justice, and how, or if, universities foster the human capabilities and aspirations of students. Does higher education make a difference to the lives of students, their families and communities? 

Prof Walker says the Research Chair on Higher Education and Human Development looks at issues of access, participation and transitions into work, as well as gender, race and social class. They use both quantitative and qualitative methods and includes a strand of participatory research projects with students. Ultimately, the research must contribute to debates, policy and practices in higher education, and a scholarly knowledge base.

Reduced emissions make for a better world

Prof Hendrik Swart chairs the research project that looks into low-energy lighting, using phosphor materials for light emitting diodes (LEDs). The Research Chair on Solid State Luminescent and Advanced Materials is situated at the Department of Physics

The research mainly focuses on better light emission of phosphor powers in LEDs.  According to Prof Swart, the long-term benefit of the research will result in more environmentally friendly devices which use less energy, are brighter and give a wider viewing field. Over the next five years they will develop and produce devices that emit better light using the substances already developed. “We need to make small devices to see if they are better than those we already have,” he says. 

Solutions to food insecurity
 

The Department of Plant Sciences’s research project dives into disease resistance and quality in field crops. Heading this Research Chair is Prof Maryke Labuschagne who focuses on crop quality breeding and disease resistance in field crops. 

Her, and her students’ research focuses on the genetic improvement of food security crops in Africa, including such staples as maize and cassava. “These crops are genetically improved for yield, drought tolerance, disease, and insect resistance, as well nutritional value,” she says. Her disease resistance research will focus on crop protein quantity and quality as well as iron, zinc, and beta-carotene biofortification of staple crops such as wheat, maize and cassava. The disease resistance-breeding project will be a continuation of the internationally acclaimed wheat rust research. 

The university considers the research chairs and the possibility of future chairs as an integral and strategic initiative to increase its national and international standing through excellent academic and research leadership.

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
