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.

First-year students encouraged to attend UFS welcoming function

2007-01-12

Main Campus, Bloemfontein

The University of the Free State (UFS) will host a welcoming function for all new first-year students and their parents on Saturday 13 January 2007 in the Callie Human Centre on the Main Campus in Bloemfontein.

The function starts at 11:00 and will be addressed by the Rector and Vice-Chancellor of the UFS, Prof Frederick Fourie. UFS staff will also be available to provide vital information to first-year students on academic matters.

Saturday’s welcoming function can assist students and parents by providing vital information on the registration process, which starts on Tuesday 16 January 2007, and the many high quality academic learning programmes on offer in six faculties at the UFS.

The UFS has split the registration process into various categories of students and students should adhere to the dates, and times which apply to them as a one-stop service will be available so as to avoid unnecessary delays in the registration process.

The registration of first-time entering first-year students who applied before 30 November 2006 to study at the Bloemfontein Campus will take place from Tuesday 16 January 2007 at the Callie Human Centre.

Senior undergraduate students (that is, students entering their second or later year of study) may register from 22 January 2007 according to a programme that was sent to all students who were registered at the UFS in 2006.

Postgraduate students, first-time entering first-year students and other students, who applied for admission to the Main Campus after 30 November 2006 and were accepted, must register at the Callie Human from 5 February 2007.

Late applications will be accepted until Monday 15 January 2007 at the Information Centre on the Main Campus’ Thakaneng Bridge.

Lectures will commence on 5 February 2007 and the registration process will end on 9 February 2007.

Vista Campus:

The Vista Campus in Bloemfontein – which was incorporated into the UFS in January 2004 – no longer accepts applications from first-year students. Such prospective students had to apply to the UFS Main Campus. Students who had been registered on the Vista Campus last year must register at the Vista Campus on the same dates as applicable on the Main Campus.

Qwaqwa Campus:

At the Qwaqwa Campus of the UFS all first-time entering first-year students must report on Sunday 14 January 2007 for orientation, after which the registration of these students will take place according to a specific programme as from Wednesday 17 January 2007. The official welcoming functioning for new first-years at the Qwaqwa Campus of the UFS will take place on Saturday 10 February 2007 at 08:00 in the Rolihlahla Mandela Hall on the Qwaqwa Campus.

First-year students who have applied to study at the Qwaqwa Campus and their parents should attend this function which fulfils the same role as the one held on the Bloemfontein Main Campus.

Detailed information on the dates and times of registration for the various faculties and academic learning programmes is available on the UFS website at www.ufs.ac.za.

Prospective students may also call the Main Campus in Bloemfontein on 051 4013000 or the Qwaqwa Campus on 058 718-5000 for more information.
