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.

Triumph in the face of adversity

At the University of the Free State (UFS) Autumn Graduation Ceremony held from 12-15 April 2016, on the Bloemfontein Campus, a record number of fourteen beneficiaries of the No Student Hungry (NSH) Bursary Programme received their degrees. This is an achievement they all feel they could not have reached, were it not for the support by NSH.

The NSH food bursary is awarded to students on the basis of financial need, academic excellence, and a commitment to serve the community. The UFS has helped over 650 students since 2011, when Prof Jonathan Jansen, Vice-Chancellor and Rector, started NSH.

These students are true beacons of inspiration and determination. Indeed, they have triumphed in the face of adversity. This is what can be said about their determination and will to succeed.

Glory, a previous recipient of the NSH bursary and a mother of two, graduated on Tuesday morning, receiving a BEd degree (intermediate phase). She stated that the NSH bursary changed her life drastically when she started receiving it.

“I used to constantly worry about my children and what they would eat. So I would sacrifice my own meals throughout the day just to make sure they have food to eat,” says Glory.

“The NSH bursary really gave me peace of mind, my school work was suffering and once I started receiving food each day, I could focus on what really mattered: my degree.”

“My goals for this year are to get a permanent job, and start receiving a stable salary. I am currently working as a temporary teacher at a primary school in Bloemfontein.

“I never would have thought that I could have made it this far. I want to pursue my postgraduate studies, to inspire my children and other students who have been in my shoes. There is help and hope. My faith also gave me refuge. Nothing that is given to me is taken for granted,” says Glory.

Another student Katlego, who graduated on 14 April 2016, receiving her BCom Human Resource Management degree. At present, she is busy with her BCom Industrial Psychology Honours. She heard about the NSH food bursary, through a friend in 2014, and has been immensely grateful for all she has received. 

“There is no shame in asking for help. There can only be hope and relief,” she said.

“I am so thankful for NSH. As part of the bursary programme, we commit to serving the community. We receive but we are also encouraged to give back. The community service projects have helped me to get out of my comfort zone, to look beyond myself and acknowledge that I am also required to give back my time to others who appreciate and cherish it.”   

The NSH students are offered not only a food bursary; they participate in student wellness and development programmes, and they are motivated and exposed to opportunities for personal growth. Students are also encouraged to be involved in university or community projects as a way of ploughing back into the community, thus creating a reciprocal cycle of giving and receiving within their community.
