Revolutionising wheat: Developing cultivars that maintain their quality in heat and drought

UFS PhD student and food scientist Schae-Lee Olckers’ research could contribute to a stable supply of good quality wheat and bread, even in the face of climate change.

Follow your passion in order to find your purpose. This is the mantra of food scientist and University of the Free State (UFS) PhD student Schae-Lee Olckers, whose research is set to improve wheat quality by identifying which types of wheat are better able to tolerate stress, and which proteins are most important for producing high-quality bread.

“By grasping this, it is possible to ensure that we continue to have a stable supply of good quality wheat and bread, even in the face of climate change,” says Olckers, who believes wheat is one of the most important food grains in the human diet, and one of the most important staple cereal crops in the world.

Her PhD study, ‘The influence of abiotic stress on gluten protein and baking quality in bread wheat’, under the supervision of Dr Angie van Biljon and Prof Maryke Labuschagne in the Department of Plant Sciences, and Prof Garry Osthoff in the Department of Microbiology and Biochemistry, is investigating how different levels of heat and drought stress – mostly due to climate change – affect the gluten protein composition of high-yield bread wheat.

Olckers is a food scientist at StartWell Foods (Pty) Ltd, a non-profit organisation that produces high-quality extrusion products for feeding schemes around the country. The products help to eliminate stunted growth among children.

Her research focuses on examining different types of wheat and investigating how proteins are affected by stressors like heat and drought, to understand how these stressors impact the quality of bread. She uses new proteomic methods to look at the different proteins in the wheat flour, to gain a better appreciation of how gluten proteins react to stress.

In this study Olckers is able to see how the proteins change in the various wheat cultivars, helping us to understand how the different types of wheat perform in baking, and how the proteins affect the final product.

She collaborates with the International Maize and Wheat Improvement Center (CIMMYT) in Mexico, that releases new wheat cultivars for developing countries. Their aim is to develop wheat cultivars that maintain their quality in different environments. To investigate the performance and characteristics of the seeds, both in the field and in the laboratory, CIMMYT did the field trials, quality assessment, and supplied the seeds for high-performance liquid chromatography (HPLC) and proteomics analysis.

Finding ways to adapt to climate change

She believes that understanding how these stressors impact the production of bread-baking quality in wheat will help scientists gain important insights into how climate change affects our food supply.

“Taking into consideration the current and projected intensifying heat and water deficit stresses, it is crucial to improve the understanding of these phenomena in order to implement new breeding strategies for sustainable wheat quality. This research could help us find ways to adapt to climate change and continue to produce high-quality wheat and bread for people around the world,” Olckers says.

UFS presents unique rally

2006-05-11

On Friday 9 June 2006 the University of the Free State (UFS) will present the second Amazing Race Rally in Bloemfontein.

The rally is presented in aid of children and babies with serious diseases in the Department of Pediatrics and Child Health in the UFS Faculty of Health Sciences. These children are in need of intensive care, and suffer from cancer, heart disease, neurological diseases and conditions, endocrinological diseases or gastro-enterological conditions.

By raising the necessary funds, equipment can be acquired to meet the unique healthcare needs of these children and babies and it will also enable the UFS to maintain the high standards of education, training and research in this field.

Last year about 12 corporate teams from among others Vodacom, Medi-Clinic, Eskom, Mimosa Mall and Nedbank and four teams from the UFS competed in the rally. The Medi-Clinic team was the winner.

This year the teams will again follow a specific route with various check points by car. Here they will have to complete activities or solve clues before receiving their clue to the next checkpoint. The teams will be travelling with cars branded with the logo of the company they represent.

Companies and institutions in Bloemfontein can enter in the rally by means of sponsoring a check point, entering a team of two persons or sponsoring some aspects of the day.

The rally will give participants an opportunity to test their knowledge of the city, as well as their time management skills, communication skills, team work and even their relationships!

The programme will start at 12:00 on the UFS Main Campus and the first team to complete this task is the winner of Bloemfontein’s second Amazing Rainbow Rally.

Extensive publicity of the event on OFM in the weeks running up to the day will ensure that participants are easily recognised and will create a measure of excitement.

Enquiries about the rally can be directed to Ms Adéle van Aswegen at (051) 401-3535 or Ms Ilse Olivier at (051) 401-2415.
