Prof Botma Visser delivered his inaugural lecture at the University of the Free State, highlighting nearly two decades of research on wheat rust and global food security.

Safeguarding one of the world’s most vital staple foods was at the heart of the inaugural lecture delivered by Prof Botma Visser, Professor in the Department of Plant Sciences at the University of the Free State (UFS), on Wednesday 3 September 2025. Prof Visser shared insights from nearly two decades of research into wheat rust – a devastating crop disease that threatens both South Africa’s harvests and global food security.

“Wheat production in South Africa is threatened by three fungal pathogens that cause rust disease on the crop. Understanding the factors that contribute to virulence on locally grown cultivars is crucial to ensure continued wheat production,” said Prof Visser.

 

The fight against evolving wheat rusts

For the past 17 years, Prof Visser’s research has focused on the genetic structure of rust populations and the risks they pose to food security. His work has shown that these populations are dynamic and constantly changing due to genetic mutations within existing races, as well as the introduction of new races into South Africa.

“Computer modelling showed that rust can spread over vast distances by prevailing winds. During the 20th Century, at least four Southern African stem rust races managed to move across the Indian Ocean from Southern Africa to Australia. South Africa, in turn, received multiple new races from mid-Africa across Zambia and Zimbabwe, without any means of stopping these introductions,” he explained.

To respond to this challenge, his team recently implemented MARPLE (Mobile And Real-time Plant disEase) diagnostics using fourth-generation nanopore sequencing technology. This approach allows the rapid characterisation of fungal isolates, specifically targeting genes linked to fungicide resistance and virulence.

“This work,” Prof Visser noted, “is part of an effort to safeguard global wheat production.”

His research is a collaborative effort with Prof Willem Boshoff (Department of Plant Sciences, UFS) and Dr Tarekegn Terefe (Agricultural Research Council – Small Grain, Bethlehem). Together, their work has positioned the UFS as an internationally recognised centre of excellence in wheat rust research.

 

About Prof Botma Visser

Prof Botma Visser obtained his BSc in Botany and Microbiology (1988), BSc Honours in Microbiology (1989), and MSc in Botany (1993) at the University of the Free State, where he also completed his PhD in Botany in 2004.

His career spans more than 18 years of research into wheat rust pathogens, combining annual surveys, race pathotyping, molecular genetics, and cutting-edge sequencing technologies. His expertise has not only advanced understanding of rust population dynamics in South Africa but also contributed to global collaborative studies on crop disease.

School of Medicine expands to provide quality tuition
2015-04-20

 

The School of Medicine at the University of the Free State (UFS) has recently extended various training platforms to provide continuous quality tuition to students.

Not only does the school boast a world-class dissection hall but now has plans for additional training facilities at two more hospitals.

The new dissection hall was completed in January 2015 with some final finishing touches that will be done shortly. The hall is newly built as the previous dissection hall has been used for undergraduate anatomy training since 1972.

Dr Sanet van Zyl, Senior Lecturer in the Department of Basic Medical Science, says owing to a prospective growth in the number of medical students as well as changing methods in teaching and learning, the need for a new dissection hall became evident to ensure that students get an optimal learning experience during dissection tuition.

“The new spacious dissection hall is equipped with special lighting and modern equipment for the training programme for second-year medical students. The hall is further equipped with modern sound and computer equipment. A unique camera system will allow students to follow dissection demonstrations on ten screens in the hall. Dissection demonstrations can also be recorded, enabling lecturers to put together new materials for teaching and learning.”

In addition to anatomy teaching for under- and postgraduate medical students, the Department of Basic Medical Science also offers anatomy teaching to under-graduate students from the School of Nursing, the School of Allied Health Professions as well as students from the Natural and Agricultural Sciences (such as students studying Forensic Science). The old dissection hall will still be used for the anatomy training of these students.

“The dissection programme for medical students is of critical importance, not only to acquire anatomical knowledge, but also for the development of critical skills and professionalism of our students. As already mentioned, these modern facilities will enable us to be at the forefront of current development in this field. This will benefit both present and future generations of medical students.”

At the same time, Prof Alan St. Clair Gibson, Head of the School of Medicine, announced that lecturing facilities are being developed at the Kimberley Hospital Complex. There are also plans for study facilities at the UFS’s Qwaqwa Campus and Bongani Hospital in Welkom. The UFS’s planning is also well underway for lecturing and residential facilities for students in Trompsburg, where students will receive training at the Trompsburg Hospital.

“We are very privileged to have these facilities and they will help us to provide world class training for students in the School of Medicine,” Prof St. Clair Gibson says.
