Schae-Lee Olckers’
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 in partnership with USA ’s Council on Economic Education 

A group of 50 teachers in Economics, learning facilitators and lecturers from eight countries attended a ‘train the trainers’ workshop this past week in Bloemfontein.  The workshop forms part of the outreach programme of the National Council on Economic Education (NCEE) in the United States of America’s (USA) effort to improve the quality of the training in Economics of teachers and lecturers across the world. 

The UFS and the Free State Department of Education are the NCEE’s first partners in Africa.  “The initiative started in the Free State because of the connection that existed between the UFS and the NCEE,” said Prof Klopper Oosthuizen, from the UFS Department of Agricultural Economics and initiator of the cooperative agreement with the NCEE.

Three faculties at the UFS are involved in the cooperative agreement namely the Faculty of Natural and Agricultural Sciences, the Faculty of the Humanities and the Faculty of Economic and Management Sciences.

A group of 84 teachers and learning facilitators in the Free State attended the ‘train the teacher’ workshop at the UFS in December 2005 in an effort to improve the quality of Economics classes at schools in the Free State.  The last national workshop will take place in June 2006 in Bloemfontein.  During this workshop a group of 40 teachers and learning facilitators in the Free State will be trained by the NCEE.    

“Because of the success with the programme in the Free State Dr Patty Elder, Vice-President of the NCEE’s national programme, announced during last week’s workshop that the initiative will now be extended to the other provinces in the country,” said Prof Oosthuizen.  According to Prof Oosthuizen discussions around a strategy to get the other provinces on board of the programme also took place between Dr Elder and Prof Herman van Schalkwyk, Dean of the UFS Faculty of Natural and Agricultural Sciences.  Prof van Schalkwyk will take the lead in this regard.  

“The presence of Dr Elder and the executive directors of similar education networks in the Ukraine and Indonesia is an indication of the NCEE’s seriousness with the programme in Africa,” said Prof Oosthuizen.

Prof Oosthuizen explained that South Africa is competing to obtain funds from the NCEE to have a total South African representation in the workshops in the following one-year training period. 

South Africa has a good chance of establishing the network quickly because of the presentation of the last national workshop in Bloemfontein in June 2006.  “We are going to try to have as much South African representation as possible at this workshop,” said Prof Oosthuizen.

Concurrent with the workshop in June 2006, a programme will be developed that will be attended by at least five other provincial education departments and representatives of five other universities.  These representatives will then be able to observe on a first-hand basis how this action learning takes place and how the participating countries plan to establish and expand their networks,” said Prof Oosthuizen.

“The NCEE has been working together with international partners since 1992 to strengthen their Economics teaching systems.  They have already succeeded in increasing literacy in Economics of schools in the USA and more than 20 East Block countries.  More than 1,5 million learners in the East Block countries have already been served by this initiative,” said Prof Oosthuizen.

According to Prof Oosthuizen the focus of the NCEE has since 2004 moved away from the East Block countries to Africa, Asia, Latin America and the Middle East.  The representatives that attended last week’s workshop were from South Africa, Egypt, Jordan, Palestine, Indonesia, Mexico, Paraguay and Uruguay.  Countries such as Egypt, who was also present at last week’s workshop, are eager to start a similar network.
