Thirteen staff members and students from the department of Plant Sciences recently attended the 51st Congress of the Southern African Society for Plant Pathology at Club Mykonos in Langebaan. In total, six papers and four posters were presented by the delegates. Prof Zakkie Pretorius was one of the invited keynote speakers, with the title “Are cereal rusts still important?” During the conference, many existing collaborations were strengthened.

Professor Robert Park, Head of Cereal Rust Research at the Plant Breeding Institute (PBI) at the University of Sydney, visited Dr Willem Boshoff and Prof Botma Visser from the Department of Plant Sciences at the University of the Free State during October, 2019. Rust researchers at the two Institutions have been involved in many collaborative projects in the past and through this visit, these ties were strengthened. During his visit, he gave a talk entitled “Approaching 100 years of cereal rust research at the University of Sydney; lessons learnt and the way ahead”.

Over the past 31 years, Prof Park established a very successful cereal rust research program at the PBI and currently has 40 staff members under his supervision. His research mandate include the monitoring of several cereal rust populations in Australia, the development and release of rust resistant wheat, rye, oat and barley varieties and the cloning of rust resistance genes from these crops.

During his talk, Prof Park emphasised that while the continuous evolution of local rust races into more virulent races remains a problem in Australia, a bigger threat is the introduction of exotic rust isolates that are genetically distinct. Since it is often difficult to accurately determine the exact origin of these incursions, they often had a bigger impact on wheat production than the local races that mostly evolve through single step mutations. These new incursions often carry more complex virulence factor combinations than the local races, thereby simultaneously rendering many cultivars susceptible. Predicting the appearance of these exotic incursions and the virulence factors they might carry, is almost impossible when considering anticipatory resistance breeding strategies. New incursions may result from human interventions such as pathogen spores sticking to travellers’ clothes.

Prof Park stressed that understanding the genetics of both the pathogens (such as how a pathogen takes over the metabolic processes of its host) and their hosts is important to manage cereal rust pathogens. Despite many challenges, they have been fairly successful with breeding for rust resistance and he estimated that this saves AUD$ 1.04 billion per year through genetic resistance. The application of new technologies like “Pathogenomics” is improving the global surveillance of rusts and assists in unravelling the molecular basis of host pathogen interactions. Advances through resistance gene cloning provide high throughput diagnostic markers for gene pyramiding which further opens the possibility of cis- and transgenic approaches.

Prof Park concluded that “as researchers we must ensure the continued translation of research outputs to the field to help farmers.” It was a great pleasure to host Prof Park and we are looking forward to further collaborate with his group to the benefit of local farmers and consumers.

Five postgraduate students (Martin Chemonges, Ettienne Theron, Jacques van der Merwe, Danette Strauss and Stephanie MacDonald) from the Department of Plant Sciences recently competed in the annual post-graduate symposium of the Department of Botany and Plant Biotechnology at the University of Johannesburg. During the symposium, each student presented results of their respective research projects. While Martin was announced as the runner-up in the PhD category, Danette and Stephanie were respectively announced as the winner and runner-up of the BSc Honors category. The department is very proud of their achievements. Prof Botma Visser and Dr Andri van Aardt accompanied the students.

Five personnel (Proff. Botma Visser, Sakkie Pretorius, Liezel Herselman, Dr. Willem Boshoff, Mrs. Cornel Bender) of the Department of Plant Sciences presented the International Cereal Rusts and Powdery Mildews Conference at the Nombolo Mdluli Conference centre in Skukuza, Kruger National Park from 23-26 September 2018. The conference which was presented under the auspices of the European and Mediterranean Cereal Rusts Foundation, attracted international delegates from as far as Canada and Australia. Besides the five personnel, three UFS post-graduate students (Ansori Mare, Howard Castelyn and Rinette Labuschagne) attended the conference. During the conference, new research on the epidemiology, population biology and management of the cereal rusts and powdery mildews, as well as the cloning of both plant disease resistance genes and pathogen avirulence genes were presented. Many current and proposed collaborative research projects between the UFS and international delegates were strengthened. Both Prof. Pretorius and Dr. Boshoff were included as co-authors on the winning poster of Jianping Zhang of the CSIRO in Australia. Besides the cutting-edge science that was presented, the game-viewing was also of the highest standard.

Prof. Zakkie Pretorius, Liezel Herselman, Botma Visser and Dr. Willem Boshoff from the Department of Plant Sciences attended the 9th Borlaug Global Rust Initiative (BGRI) Technical Workshop in Marrakech, Morocco from 14-17 April 2018. Howard Castelyn and Martin Chemonges, current PhD students, and Tegwe Soko, PhD student from Zimbabwe who will graduate in June, completed the Southern African delegation. The theme of the workshop was “Delivering genetic gain in wheat” and was attended by 333 delegates from 52 countries from around the world. Four poster presentations were made of which the “Innovative manufacturing of a cereal rust inoculation device” poster by Prof. Pretorius won the prize for best poster at the workshop while the “Gone with the wind: Revisiting stem rust dispersal between southern Africa and Australia” poster by Prof. Visser was announced as runner-up.

The UFS delegates attending the post-graduate symposium of the Dept. Botany and Plant Biotechnology University of Johannesburg, were (from left to right) Dinè Pretorius, Andri van Aardt, Marlese Bester, Ansori Maré, Botma Visser and Clausanne Esterhuizen.

Four post-graduate students from the Department of Plant Sciences recently attended the annual post-graduate symposium of the Department Botany and Plant Biotechnology, University of Johannesburg. The students were Ansori Maré (PhD), Marlese Bester (MSc), Clausanne Esterhuizen (BSc Honors) and Dinè Pretorius (BSc Honors). Prof Botma Visser and Dr Andri van Aardt accompanied them to the two-day event.

During the symposium, each student competed against their peers from UJ when each presented a 10-minute paper on their research results for their respective degrees. While all four students presented excellent papers (and received complements for it), Dinè Pretorius was awarded with the prize for the best BSc Honors presentation at the symposium. The title of her presentation was “Evaluation of sunflower as a potential soil rehabilitation crop” and the work was completed under the supervision of Dr Gerhard Potgieter. Congratulations Dinè!
