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.

The University of the Free State (UFS) has recently appointed four acclaimed, top class musicians in its Odeion String Quartet. The quartet, which was established in 1991, is the only resident quartet at a South African university.

The new members who have been appointed are: Denise Sutton, first violinist and leader of the string quartet, Sharon de Kock, second violinist, Jeanne-Louise Moolman, violist, and Anmari van der Westhuizen, cellist. Anmari is the latest addition to the quartet.

Denise Sutton is well-known, inter alia, as longtime concert master of the PACT orchestra, as leader of the Rosemunde Quartet, for her involvement with the Chamber Orchestra of South Africa (COSA), and as a inspiring teacher at the University of Pretoria.

Jeanne-Louise Moolman has about twenty years experience as principal violist of professional orchestras in Gauteng and was leader of the violas in the Johannesburg Philharmonic Orchestra and COSA. She was also a founder member of the Rosemunde Quartet.

Sharon de Kock, formerly from Cape Town, studied at the University of Cincinnati, played in symphony orchestras in Peru, Costa Rica and the USA, and was a violin teacher in Mexico and Costa Rica until her return to South Africa in 2007.

Anmari van der Westhuizen, formerly from Stellenbosch, is one of the most sought-after cellists in South Africa, has been the conductor and director of the UCT String Ensemble since 1999, and spent eight years as soloist and chamber musician in Europe from 1988-1996.

The new quartet will be launched at a concert on 6 November 2008 in the Odeion on the Main Campus in Bloemfontein.

The new appointments follow after three former members of the quartet – Jürgen Schwietering, John Wille and Abrie de Wet – retired or left Bloemfontein at more or less the same time. Michael Haller, longtime cellist of the quartet, will also be retiring at the end of 2008. These developments mean that the Odeion String Quartet is literary brand new.

The new appointment creates exciting new opportunities for learners and students to be taught by excellent lecturers at the music department of the UFS. The new players also strengthen the Free State Symphony Orchestra significantly, since they will fill the four principal positions in the strings.

“The Odeion String Quartet is a flagship of the UFS and it symbolises our commitment to the arts. It also plays an important strategic role in the development of symphony orchestra music and classical music training in the Free State. It is an essential part of UFS regional collaboration with e.g. the Free State Symphony Orchestra, the Mangaung Strings Programme, the Free State Musicon, the Free State provincial Department of Arts and Culture and Pacofs.This is why a real attempt was made to obtain top class musicians, to attract the best in the country. We are pleased that such a strong group could be appointed,” said Prof. Frederick Fourie, chairperson of the String Quartet’s management committee and outgoing Rector and Vice-Chancellor of the UFS.

Most string quartets abroad are affiliated with a higher education institution, which enables a higher level of playing as there is more time for preparation and to study the repertoire. “We appreciate the university’s confidence in us and for the opportunity to explore the intricacies of ensemble playing. We hope that we can produce inspiring performances for our audiences and students,” said Denis Sutton, new leader of the string quartet.
