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.

For this year’s Summer School programme, Prof Paul Grobler, from the University of the Free State Department of Genetics focuses on research about the conflict between monkeys and humans in areas where monkeys are regarded as problem animals.

Global expert part of research

This year, Prof Grobler is hosting a group of students and lecturers from the United States of America (USA). The group includes Prof Trudy Turner from the University of Wisconsin-Milwaukee (UWM), a global expert on vervet monkeys. She has been working with the Department of Genetics at the UFS for the past fifteen years, and has also been appointed as an Affiliated Professor in the department.

“The Summer School programme is an opportunity for the American Primatology students to gain practical experience in Africa,” says Prof Grobler.

International interest in Summer School

This year’s Summer School programme involves four lecturers and nine students. The lecturers are from the University of Wisconsin-Milwaukee (UWM), the University of California, Los Angeles (UCLA), Boston University, and Central Washington University.

“We use the genetic information to determine
how monkeys historically infiltrated the
different areas in South Africa.”

This year’s focus is on the genetic structure of the monkeys in South Africa, and research that is being done on the differences and similarities in monkeys from different areas. “We use the genetic information to determine how monkeys historically infiltrated the different areas in South Africa,” says Prof Grobler.

Local nature reserve acting as host

The group will perform field work, including observing monkeys in the Soetdoring Nature Reserve, as well as laboratory work in the department, where they will be assisted by two laboratory technicians.

Two years ago, Prof Grobler and his department tested this idea on a smaller scale, and now they hope to make this a regular event.
