Dr Angeline van Biljon was elected as a member of the Southern African Plant Breeders’ Association (SAPBA) executive committee.

Ever wondered how seedless fruit such as lemons, watermelons, and grapes came to be?

Dr Angeline van Biljon, Senior Lecturer in the Department of Plant Sciences at the University of the Free State (UFS), was recently elected as a member of the Southern African Plant Breeders’ Association (SAPBA) executive committee where she will serve until March 2022.

She says it is a privilege to be a member of the team. “It is an opportunity to bring plant breeding to the community so that more people can know about the subject. For example, that seedless lemons, grapes, and watermelons does not just happen; that orange sweet potatoes with high beta-carotene are bred to combat vitamin A deficiency; and that wheat quality is important to make a good loaf of bread.”

This position also brings with it the possibility for her students to work closely with people in industry. “Other members of the committee are breeders in seed and breeding companies,” explains Dr Van Biljon.

Contributing on other platforms 

She was nominated and elected for this position during the SAPBA conference that was held at the Future Africa campus in Pretoria. Besides serving on the executive committee of SAPBA, she is involved with and are serving on several other platforms where she is making a difference in the plant breeding industry. 

Dr Van Biljon collaborates on wheat quality with researchers in the wheat industry at the Agricultural Research Council (ARC), Small Grain in Bethlehem. “I’m also a committee member of the Cereal Science and Technology – Southern African Association.”

For the past two years, she has been giving online lectures on biofortification as part of a National Research Foundation/Swedish Foundation for International Cooperation in Research and Higher Education (STINT/NRF) group in Alnarp in Sweden. However, she states a working visit to the Nanjing Agricultural University in Nanjing, China as one of her biggest highlights.


Today, I want to help students see the difference plant breeding can make in crop improvement and food security.


The difference plant breeding can make 

Although genetics was one of her passions as student, she later found herself as a flower breeder at the ARC Roodeplaat. Years later, she returned to the UFS to complete her PhD in Plant Breeding. And today, she wants to help students see the difference plant breeding can make in crop improvement and food security.

Currently, Dr Van Biljon is focusing on her research, which is the study of the nutritional value of various crops by determining, among others, the beta-carotene values of butternuts, the starch quality of wheat, and the tryptophan value of quality protein maize. “I also look at the influence of abiotic stress on the crop quality and nutritional value of various crops,” she adds.

Champagne and cancer have more in common than you might think

No, a glass of champagne will not cure cancer....

…But they have more in common than you might think.

Researchers from the Departments of Microbial Biochemical and Food Biotechnology, Physics and the Centre for Microscopy at the University of the Free State in South Africa were recently exploring the properties of yeast cells in wine and food to find out more of how yeast was able to manufacture the gas that caused bread to rise, champagne to fizz and traditional beer to foam. And the discovery they made is a breakthrough that may have enormous implications for the treatment of diseases in humans.

The team discovered that they could slice open cells with argon gas particles, and look inside. They were surprised to find a maze of tiny passages like gas chambers that allowed each cell to ‘breathe.’ It is this tiny set of ‘lungs’ that puts the bubbles in your bubbly and the bounce in your bread.

But it was the technique that the researchers used to open up the cells that caught the attention of the scientists at the Mayo Clinic (Tumor Angiogenesis and Vascular Biology Research Centre) in the US.

Using this technology, they ultimately aim to peer inside cells taken from a cancer patient to see how treatment was progressing. In this way they would be able to assist the Mayo team to target treatments more effectively, reduce dosages in order to make treatment gentler on the patient, and have an accurate view of how the cancer was being eliminated.

“Yes, we are working with the Mayo Clinic,” said Profes Lodewyk Kock from the Microbial, Biochemical and Food Biotechnology Department at the UFS.

“This technique we developed has enormous potential for cell research, whether it is for cancer treatment or any other investigation into the working of cells. Through nanotechnology, and our own invention called Auger-architectomics, we are able to see where no-one has been able to see before.”

The team of Prof Kock including Dr Chantel Swart, Kumisho Dithebe, Prof Hendrik Swart (Physics, UFS) and Prof Pieter van Wyk (Centre for Microscopy, UFS) unlocked the ‘missing link’ that explains the existence of bubbles inside yeasts, and incidentally have created a possible technique for tracking drug and chemotherapy treatment in human cells.

Their work has been published recently in FEMS Yeast Research, the leading international journal on yeast research. In addition, their discovery has been selected for display on the cover page of all 2013 issues of this journal.

One can most certainly raise a glass of champagne to celebrate that!
