Marcele Vermeulen, a graduate from the Department of Plant Sciences, explores possible threats to crop production; contributing to food security in South Africa.
Global food security is currently threatened both by climate change and the low diversity of crops relied on by humankind to feed a growing world population. Marcele Vermeulen, a graduate in the Department of Plant Sciences who will receive her PhD at the December graduation ceremonies at the University of the Free State (UFS), is part of a team that is working hard to add to the diversity of staple foods in South Africa.

In the drive to focus on alternative crops, Marcele is researching the crop, Amaranthus cruentus, (grain amaranth). It is more tolerant to environmental stress for large-scale production, thereby also diversifying staple crops.

Relatively new development

“Amaranthus cruentus is an excellent candidate due to its high nutritional value and tolerance to drought and high temperatures. It can be mixed with conventional maize meal, to increase the protein intake of its consumers,” said Marcele.

The production of A. cruentus as a grain crop in South Africa is a relatively new development.

In her research, exploring the possible threats to crop production and paying particular attention to dominant plant pathogens in the Amaranthus cruentus, Marcele found a correlation between fungal pathogens and insect pests. 

Insect pests can influence plant diseases

Although reports on fungal pathogens and pests specific to A. cruentus are limited to and information for South Africa is limited to this study, there is a possibility that by controlling insect pests such as weevils, one might also be able to control fungal pathogens of Amaranthus cruentus.

Marcele believes that control of weevil pests should thus be the focus of future pest and pathogen management strategies and breeding programmes in A. cruentus.  

“Knowledge gained in my thesis will hopefully aid in the development of future cultivation practices, integrated pest/pathogen management programmes, as well as for the registration of crop protection products for A. cruentus,” Marcele added.

New modern dissection hall ensures optimal learning experience for medical students

The School of Medicine in the Faculty of Health Sciences at the university opened its doors on 6 June 1969. Three years later, a dissection hall for anatomy training was added to the school. This year, because of the prospective growth in the number of medical students as well as in changing methods of teaching and training, a new modern Dissection Hall has been completed on the Bloemfontein Campus. This ensures that students receive an optimal learning experience during dissection tuition.

The Dissection Hall was built as a double-storey wing to the existing Francois Retief Building. Covering 733m², the new facility is on the first floor - the same level as the existing hall - to allow easy access between the two facilities. The ground floor, totalling 465m², houses various offices for 16 people.

The new hall has special lighting and modern equipment for the training of second-year medical students in dissection. The hall also has high-quality sound and computer equipment. A unique camera system allows students to follow dissection demonstrations on 10 screens in the hall. Dissection demonstrations are recorded, enabling lecturers to compile new visual aid material for teaching and learning.

The dissection programme for medical students is of critical importance, not only for acquiring anatomical knowledge, but also for developing critical skills in medical students.

The new hall is also used for clinical workshops and postgraduate teaching seminars, as well as workshops in orthopaedics (shoulder, hip, and knee), otorhinolaryngology, cardiothoracic surgery (valve and endoscopy), and anaesthesiology, among others.

Both present and future generations of medical students will benefit from this new world-class facility.
