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 discontinues one Masters programme

2006-07-26

As from next year, the University of the Free State (UFS) will no longer offer one of its specialist master’s degrees in education – the M Ed in Education Management.

The other six M Ed programmes that are currently being offered at the UFS will continue as normal.

The decision to discontinue one of the M Ed programmes follows a national review of M Ed programmes in Educational Management and Leadership by the Higher Education Quality Committee (HEQC) of the Council on Higher Education (CHE).

Of the 23 tertiary institutions whose M Ed programmes in Educational Management and Leadership were reviewed by the HEQC, only 7 received full accreditation.

“The findings of the HEQC affect only one of our M Ed degree programmes, namely the M Ed in Educational Management,” said Prof Magda Fourie, Vice-Rector: Academic Planning at the UFS

“We will be paying full attention to the findings of the HEQC with a view to correcting some of the shortcomings that have been identified by the HEQC and will consider submitting a reviewed proposal for such a qualification in two years time,” she said.

According to Prof Fourie, the programme currently has 30 students enrolled. “These students – spread across their first and second years of the degree programme – will be allowed to complete their studies with the full support of the UFS and the School of Education,” said Prof Fourie.

“The qualification that has been awarded to students who have already completed their studies for this specific M Ed in Education Management degree programme remains a valid qualification and is not affected by the HEQC review,” said Prof Fourie.

She said the UFS welcomed the efforts of the HEQC to ensure that all academic programmes offered by higher education institutions meet certain standards.

“One of the primary problem areas in the M Ed in Educational Management offered by the UFS identified by the HEQC, was that the programme is too practice orientated and must be more theoretical to comply with the academic requirements of a master’s degree. This was a result of the fact that the programme was initially compiled in consultation with principals and the provincial Department of Education to address their needs,” said Prof Fourie.

“The UFS will in the mean time offer an advanced certificate in Educational Management and Leadership from next year. This is a new course that will stretch over a period of two years and will ensure that we can still address the needs of teachers and principals,” said Prof Fourie.

“The UFS remains committed to providing top quality degree programmes in all its six faculties and will continue to work with the HEQC in ensuring that this actually happens,” said Prof Fourie.
