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 to host one the most prestigious seminars in leadership

2004-09-28

The Business School of the University of the Free State (UFS) will be hosting the Central Region’s screening of the largest global satellite broadcast of the 2004 Living Leadership: Delivering Results the Right Way event.

The event, which will take place on 21 October 2004 from 09:00-16:30 at the Albert Wessels Auditorium on campus, will be up linked from Atlanta, Georgia, USA, and will be broadcasted via satellite to 95 cities in two countries.

“This is a once in a lifetime opportunity for leaders in the Central Region to gain exposure to the pioneers in the international leadership field,” said Prof Helena van Zyl, Director of the UFS’s School of Management.

The global satellite simulcast will bring together a powerful diverse group of the world’s leading business authorities. This includes Mr Donald Trump, chairman of The Trump Organisation; Mr Mikhail Gorbachev, Nobel Peace Prize Winner and former president of the Soviet Union; Mr Jim Collins, speaking on his recent best-seller, Good To Great; Mr Peter Drucker, father of management and author of The Effective Executive; Ms Rosabeth Moss Kanter, professor at Harvard Business School; Mr Ken Blanchard, best-selling author of The One Minute Manager; Mr John C Maxwell, best-selling author of The 21 Irrefutable Laws of Leadership and acclaimed speaker; Mr Russell Simmons, entrepreneur and co-founder of Def Jam Records and Mr Larry Bossidy, co-author of the best-seller, Execution: The Discipline of Getting Things Done.

According to Prof Van Zyl the Living Leadership global satellite broadcast will give attendants exclusive access to the Financial Mail’s Executive Panel. It will also give local executives and renowned leaders the opportunity to share their interpretation of leadership in practical, relevant terms.

Mr Jack Welch’s executive assistant and author of Managing Up, Ms Rosanne Badowski and Ms Caroline Kepcher, an executive vice president to Mr Donald Trump and a lead role on NBC’s hit show, The Apprentice, will join the panel with a special session.

Each of the cutting-edge insights shared by this gathering of world-class leadership authorities will deliver effective benchmarks which teams will use to shape their business outcomes.

The cost is R950,00 per person (group discount is also available) – this includes the receipt of two free issues of the Financial Mail. Tickets are available at Computicket.
