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 launches focused research niche areas

2009-11-20

The University of the Free State (UFS) will launch its six research niche areas, the Strategic Academic Clusters, from 23-25 November 2009 on its Main Campus in Bloemfontein.

These Clusters represent a move from a fragmented to a more focused approach to research development at the UFS and will in future direct the University’s research endeavours.

“The UFS is increasingly operating in a competitive environment where South African universities no longer compete only with their national counterparts, but also internationally. With the Clusters the University will follow a focused approach to the strategic selection of niche knowledge platforms and research areas,” says Prof. Frans Swanepoel, Director of Research Development at the UFS.

The Clusters are: Water management in water-scarce areas; New frontiers in poverty reduction and sustainable development; Transformation in highly diverse societies; Technologies for sustainable crop industries in semi-arid regions; Materials and nanosciences; and Advanced biomolecular research.

“The Clusters embody the pursuit of quality and excellence and the name signifies the University’s concern not only with research, but also with under- and postgraduate teaching and learning. The vision is that the Cluster activities will not only drive world-class research outputs, but also contribute to internationally renowned graduate programme activities,” says Prof. Swanepoel.

Each of the Clusters is led by a dedicated director who provides academic leadership, facilitates cutting-edge research, leverages multidisciplinary synergies and coordinates the overall Cluster activities.

Next week’s launch programme will start on Monday, 23 November 2009 with a gala dinner, followed by a plenary symposium on Tuesday, 24 November 2009, during which the Clusters will be introduced.

Several national and international experts in the fields covered by the Clusters will take part in this symposium. They are, amongst others: Dr Danny Walmsley from St Mary’s University in Canada; Dr David Wolfe from Cornell University and Dr David Clark from the National Institute of Health, both in the USA; Mr Mark Ashley from the Desert Knowledge Cooperative Research Centre in Australia; Dr Ian Goldman from the Office of the Presidency in South Africa; Prof Peter Ewang from the South African National Development Agency; Mr Willem Louw from Sasol Technology; and Dr Pumla Gobodo-Madikizela from the University of Cape Town.

On Wednesday, 25 November 2009 each Cluster will present its own symposium.
