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.

Kovsie community pledge to advance equality and eradicate racism

On Monday 13 April 2015, the University of the Free State drew a line in history. Staff and students united in a singular vision: equality.

Since March 2015, the Institute for Reconciliation and Social Justice, together with the SRC, has launched the No-to-Racism/Yes-to-Equality Campaign across all three campuses with tremendous success. This campaign has now reached a high point at which the Kovsie community pledge their commitment to entrenching a culture of equality at the university. The first pledge ceremony took place on 13 April 2015 at the Bloemfontein Campus. Kovsies thronged to place their inked thumbprints on pledge posters in an inspirational show of solidarity.

“The key to transformation,” Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS, said, “is putting yourself in the shoes of the other person.” When you look past yourself and acknowledge others’ experiences, the world starts to look different. A pledge, Prof Jansen continued, is a solemn promise – not only to stop bad behaviour, but to go forward resolutely with good behaviour. “You do not change a campus, you do not change a country, without being courageous,” Prof Jansen said.

The message from Mosa Leteane, President of the Student Representative Council (SRC), echoed the same belief. “Today,” Leteane said, “the UFS takes a bold and courageous step toward equality.” This new generation, which includes young people from all races, has started a new revolution. A generation that says no to discrimination and yes to equality. “We cannot afford to be ignorant or indifferent,” Leteane urged.

The remaining two campuses will also have an opportunity to publically pledge their support on the following days:
Qwaqwa Campus: Wednesday 15 April 2015
South Campus: Friday 17 April 2015

To enable the university to go beyond dialogues and consultation towards active decision-making, a University Assembly will be held on Tuesday 28 April 2015. The assembly will serve as a space for critical engagement among all university stakeholders to focus on issues such as symbols, policies, practices, and curriculum. Staff and students are encouraged to submit matters for discussion to JC van der Merwe (vdmjc@ufs.ac.za) before 22 April 2015.

The No-to-Racism/Yes-to-Equality Campaign is aligned with the declaration made by the UFS Council in November 2014, in which it states that “the Council of the University of the Free State believes very strongly in the human dignity, equality, and freedom of all people.”
