The Southern African Plant Breeders’ Association (SAPBA) recently bestowed prestigious awards upon Prof Zakkie Pretorius, Research Fellow in the Department of Plant Sciences at the University of the Free State (UFS), and Prof Liezel Herselman, Associate Professor in the same department. This institution strives to maintain high ethical standards and norms, contributing to stable, sustainable agriculture.

During the 13th Southern African Plant Breeders’ Association symposium, Prof Herselman was presented with a Fellow Award and Prof Pretorius with Honorary Membership. They received the awards for their services to and promotion of the SAPBA objectives, together with their exceptional contributions to plant breeding. 

Provide food for the nation
Over the years, Prof Pretorius, who has extensive expertise in diseases of field crops – more specifically the rust diseases of small grain cereal crops – has played a significant role in providing pathology support to the plant breeding industry. He has also conducted ground-breaking pathology research on rust diseases in field crops. In 2019, he co-authored an article that appeared in Nature, the world’s leading multidisciplinary science journal. He is also shortlisted as a 2020 finalist in the Lifetime Award and Special Theme Award (Plant Health) of the National Science and Technology Forum. Furthermore, he regularly attended and participated in biennial conferences and supervised plant breeding students working on plant disease projects. 

Prof Herselman contributes to plant breeding in Southern Africa by training and mentoring the plant breeders of the future. “As a lecturer of fourth-year and honours Plant Breeding students, as well as supervisor and promoter of master’s and doctoral students, I am in the fortunate position to teach and mentor my students in one of the newest fields of plant breeding, namely marker-assisted plant breeding. All future plant breeders need this knowledge to make a success of their breeding programmes. Our students are the future plant breeders who will provide food to the nation,” she says. 

"As a plant pathologist, I am privileged to have been able to contribute to the quest for disease resistance in crop improvement and to have been recognised for it.” – Prof Zakkie Pretorius
The highest honour
Prof Pretorius view recognition by the industry – in this case, the plant breeding fraternity – as the highest honour for someone working in agricultural science. “As a plant pathologist, I am privileged to have been able to contribute to the quest for disease resistance in crop improvement and to have been recognised for it. I am also extremely grateful to colleagues and co-workers who have contributed over many years to the establishment of a productive and influential research group at the UFS,” he says.

Prof Herselman shares this sentiment. She says: “It means so much to me to know that I have made a difference and an impact on my students’ lives. It is a privilege to have the opportunity to work with under- and postgraduate students and to see them grow.”

She continues: “We strive to send out well-rounded students who can make a difference in the workplace and the community. This award means that I have succeeded in this goal, even though I do my work because I am passionate about it and not to receive recognition.”

Fight against fungal disease continues
Prof Pretorius continues to be involved in studies on host plant resistance and pathogenic variability. 

As a molecular plant breeder, Prof Herselman is pushing on with research focusing on the development of wheat lines with improved disease resistance. The work that she is doing makes a difference on both national and international level. “As part of my current research programme, we have made rust- and Fusarium head blight-resistant wheat lines available to South African breeding companies for use in their breeding programmes. The lines developed at the UFS will in a small way contribute towards the fight against fungal diseases in South Africa, thus securing the yield and livelihoods of farmers and consumers,” she says.

Her master’s and doctoral students who have completed their studies, also take the knowledge they gained at the UFS back to their countries and workplaces where they ultimately add value, especially contributing towards the fight against hunger. 

"“We strive to send out well-rounded students who can make a difference in the workplace and the community. This award means that I have succeeded in this goal, even though I do my work because I am passionate about it and not to receive recognition.” – Prof Liezel Herselman

UFS boasts with world class research apparatus
2005-10-20

 

 

At the launch of the diffractometer were from the left Prof Steve Basson (Chairperson:  Department of Chemistry at the UFS), Prof Jannie Swarts (Unit for Physical and Macro-molecular Chemistry at the UFS Department of Chemistry), Mr Pari Antalis (from the provider of the apparatus - Bruker SA), Prof Herman van Schalkwyk (Dean:  Faculty of Natural and Agricultural Sciences at the UFS), Prof André Roodt (head of the X-ray diffraction unit at the UFS Department of Chemistry) and Prof Teuns Verschoor (Vice-Rector:  Academic Operations at the UFS).

UFS boasts with world class research apparatus
The most advanced single crystal X-ray diffractometer in Africa has been installed in the Department of Chemistry at the University of the Free State (UFS).

“The diffractometer provides an indispensable technique to investigate compounds for medicinal application for example in breast, prostate and related bone cancer identification and therapy, currently synthesized in the Department of Chemistry.  It also includes the area of homogeneous catalysis where new compounds for industrial application are synthesised and characterised and whereby SASOL and even the international petrochemical industry could benefit, especially in the current climate of increased oil prices,” said Prof Andrè Roodt, head of the X-ray diffraction unit at the UFS Department of Chemistry.

The installation of the Bruker Kappa APEX II single crystal diffractometer is part of an innovative programme of the UFS management to continue its competitive research and extend it further internationally.

“The diffractometer is the first milestone of the research funding programme for the Department of Chemistry and we are proud to be the first university in Africa to boast with such advanced apparatus.  We are not standing back for any other university in the world and have already received requests for research agreements from universities such as the University of Cape Town,” said Prof Herman van Schalkwyk, Dean:  Faculty of Natural and Agricultural Sciences at the UFS.

The diffractometer is capable of accurately analysing molecules in crystalline form within a few hours and obtain the precise geometry – that on a sample only the size of a grain of sugar.   It simultaneously gives the exact distance between two atoms, accurate to less than fractions of a billionth of a millimetre.

“It allows us to investigate certain processes in Bloemfontein which has been impossible in the past. We now have a technique locally by which different steps in key chemical reactions can be evaluated much more reliable, even at temperatures as low as minus 170 degrees centigrade,” said Prof Roodt.

A few years ago these analyses would have taken days or even weeks. The Department of Chemistry now has the capability to investigate chemical compounds in Bloemfontein which previously had to be shipped to other, less sophisticate sites in the RSA or overseas (for example Sweden, Russia and Canada) at significant extra costs.
