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.

UFS law students sit in on exceptional case in the Supreme Court of Appeal
2011-09-21

 

At the Supreme Court of Appeal were, from left to right: Dr Beatri Kruger, lecturer in our Department of Criminal and Medical Law at the Faculty of Law; Adv. Ann Skelton, Amicus Curiae instructed by the Restorative Justice Centre; Ms Matsepo Soko, post-graduate student in Criminal Law; and Prof. Annette van der Merwe from the University of Pretoria.

Fourth-year and master’s-degree students, from our Faculty of Law, had the privilege of attending the hearing of one of their prescribed cases in the module, Criminal Law, namely the State versus Tabethe, in the Supreme Court of Appeal. Apart from the fact that they could attend the hearing, the students were also addressed by experienced legal experts, Adv. Ann Skelton (amicus curiae, instructed by the Restorative Justice Centre) and Prof. Annette van der Merwe from the University of Pretoria, on the broad outlines of the case.

In this case, the accused was found guilty of raping his fifteen-year-old stepdaughter. The court imposed a sentence of ten years’ imprisonment, suspended in full, but with certain conditions. The conditions include 800 hours’ community service and stipulate that the accused has to follow a rehabilitation programme and that he has to give 80% of his income to the family in order to support the victim and her family.
 
This was the first rape case where, in following a restorative justice approach, exceptional conditions were imposed to address the interests of the victim who wants to proceed with her studies. The State appealed against the sentence.
 
Dr Beatri Kruger, lecturer in our Department of Criminal and Medical Law, who prescribed this case for the students, said, ‘The law students were indeed privileged to attend this auspicious and enriching occasion, which provided them with an insightful experience of how the law works in practice.’
