The Centre for Microscopy (CFM) in the Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS) unveiled a sophisticated JEOL High Resolution Transmission Electron Microscope (HRTEM) during a two-day microscopy conference on 14 and 15 March 2023. The microscope is part of a larger investment into research equipment worth R65 million. 

Speaking at the opening of the conference, Prof Corli Witthuhn, out-going Vice-Rector: Research and Internationalisation, said the microscope purchase “is a significant milestone in the university’s bid for cutting-edge research”. The HRTEM is part of a larger consignment of JEOL equipment at the UFS and, according to Dr Sarah Harper from JEOL UK, it places the UFS in a unique position.  

UFS at the forefront in using electron microscopes  

The HRTEM microscope can be utilised across disciplines and will give the UFS an advantage in uncovering new solutions and creating national and international interdisciplinary research collaborations. “The UFS is at the forefront in this field in SA and continues to push the boundaries,” Prof Witthuhn said. This move will also positively impact the training of honours, master’s, and doctoral students. 

Prof Danie Vermeulen, Dean of the Faculty of Natural and Agricultural Sciences, reiterated Prof Witthuhn’s sentiments by saying that this equipment will set the faculty apart from its competitors. “The faculty already reached the goals of Vision 130 by being proactive,” he said. In the past seven years more than R300 million worth of equipment was acquired by the faculty, but he added that to be the best is not just about the best equipment – “the data coming from using this equipment is what will make the real difference”.

Road to the JEOL HRTEM started in 2018

The process of acquiring a HRTEM microscope started in 2018 and was concluded with the purchasing of the JOEL microscopes in March 2020, a few weeks before the first COVID-19 lockdown. The purchase was made possible through the collaboration between the faculties of Natural and Agricultural Sciences and Health Sciences. Thanks to the dedication of staff members in the Centre for Microscopy and Physics, it was possible to accept delivery of the new HRTEM in June 2021. Prof Koos Terblans, Head of the Physics Department and the Centre for Microscopy, who led the entire project, said this was one of the “proudest moments in my career”.  

Installing the equipment involved various university resources, including the University Estates Department, which had to make additional structural changes to the room where the equipment is housed. This included digging two metres into the existing floor and placing the HRTEM on a 70-tonne solid concrete block, to ensure that the equipment was secure and vibration free.

Prof Terblans said now that the HRTEM from JEOL and its supporting equipment – the final piece of the R65 million research investment puzzle – is part of the faculty’s resources, it is up to the scientists and academics to utilise it for innovative research, enhance research productivity, and foster new collaborations.

A researcher in the Department of Plant Sciences at the University of the Free State (UFS), Prof Zakkie Pretorius, received the prestigious Grain Producer of the Year Inspiration Award during the annual gala event of Grain SA. Grain SA provides strategic commodity support and services to South African grain producers to assist in the sustainability of the sector.

This award is presented to individuals or organisations in appreciation of excellent contributions to the grain industry. These individuals have also achieved extraordinary results in their respective fields.

Research in the interest of food security
Prof Pretorius has been involved in research on plant diseases and food crops for the past 38 years. His research focus, rust diseases in crops, is especially important for food security.  

According to Prof Pretorius, who collaborates with an extensive network of specialist colleagues, his research covers a variety of topics including rust race identification, the discovery of new resistance genes, characterisation of resistance expression in plants, and the mapping of genes. His focus is not only on wheat, but he also researches rust diseases in oats, barley, maize, dry beans, lentils, sunflowers, and soybeans.

Breeding of rust-resistant varieties gains scientific basis
Locally, he has been contracted for several years by the Winter Grain Trust to annually evaluate commercial wheat cultivars and elite germplasm. This information is regularly passed on to the relevant seed companies and breeders, and is also included in the production guidelines of the Agricultural Research Council for disease risk assessment. His research places the breeding and selection of rust-resistant varieties on a solid scientific foundation. A living collection of rust fungus cultures and a large germplasm collection are maintained at the UFS under his supervision.
