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.

A team of cardiac doctors associated with the Robert WM Frater Cardiovascular Research Centre at the University of the Free State’s (UFS) Faculty of Health Sciences has commenced with a pioneering research project regarding idiopathic dilating cardiomyopathy.  

An Afrocentric research focus
Prof Francis Smit, Head of the Department of Cardiothoracic Surgery at the UFS and Head of the Frater Centre, describes dilating cardiomyopathy as a heart muscle disease that is quite common, particularly among people of African descent. The disease weakens the heart muscle, which in turn leads to heart failure.

“To date there is no curable treatment for this condition and 50% of patients that have shown heart failure, died within a period of five years. The causes of this condition have been unknown in the majority of patients. But over the past few years major strides have been made where virus infections of the heart muscle or myocarditis have been identified as a possible underlying cause. Various genetic diseases are also linked to it,” says Prof Smit.

International collaborations ensure success
According to Prof Smit, the project is being run in conjunction with Prof Heinz-Peter Schultheiss of the Charité University and the Institute for Cardiac Diagnostics and Therapy in Berlin, Germany.

“We have been working on the project over the past 18 months and I have twice visited Prof Schultheiss in Germany. He is now visiting us in Bloemfontein. We have established a collaborative project focused on patients in central South Africa”.
Prof Schultheiss is a world leader regarding the diagnosis, pathology and treatment of dilating cardiomyopathy, says Prof Smit.

“He brings a lifetime of research experience to Bloemfontein and is internationally renowned as the father of myocardial or heart muscle biopsies.

“His pioneering work on the discipline has led to diagnostic accuracy that has induced purposeful and personalised treatment of dilating cardiomyopathy and has brought about dramatic changes in some subsets of patients’ life expectancy and their cure.”

Solving problems close to home
According to Prof Mokoali Makatoko, Head of the Department of Cardiology, there are more than 1500 new cases of heart failure identified annually at the Universitas Academic Hospital, of which approximately 30% are attributed to cardiomyopathy. “With the use of endomyocardial biopsies the team hopes to treat viruses unique to Southern Africa as well as other underlying causes of dilating cardiomyopathy.”

Prof Stephen Brown, Head of Paediatric Cardiology at the Universitas Academic Hospital, says children suffering from this disease never reach a mature age and those under his supervision will also be undergoing these tests. Various other departments at the UFS will also participate in this project. Profs Makatoko and Brown did the first four endomyocardial biopsies under the management of Prof Schultheiss during the past week. The results will be available in the coming weeks after which the project will be officially launched and patient recruitment will start in earnest.
