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.

Lecture by Judge Albie Sachs: ‘Sites of memory, sites of conscience’
2015-03-23

Judge Albie Sachs

Human rights activist and former Constitutional Court Judge, Albie Sachs, will deliver a public lecture on the Bloemfontein Campus. The topic of his discussion will be ‘Sites of memory, sites of conscience’. This lecture will form part of a series that focuses on how the creative arts represent trauma and memory – and how these representations may ultimately pave the way to healing historical wounds.

The details of the event are:
Date: Thursday 26 March 2015
Time: 12:30
Venue: Albert Wessels Auditorium, Bloemfontein Campus
RSVP: Jo-Anne Naidoo at Naidooja@ufs.ac.za
A South African Sign Language interpreter will be present at the event.

Joining Judge Sachs on stage as respondent will be Dr Buhle Zuma, a young scholar and lecturer at the University of Cape Town's Psychology Department.

Expressing experiences of trauma
Judge Sachs is no stranger to the use of the arts as a way of expressing the inarticulable and overwhelming experiences of trauma. Targeted as an anti-apartheid freedom fighter, he lost his right arm and was blinded in one eye in a car bomb attack in 1988. As a judge of the Constitutional Court, he spearheaded conversations about the role of the arts in our constitutional democracy. This has led to the installation of some of the best artworks by South African artists at the Constitutional Court.

Vice-Chancellor’s Lecture Series on Trauma, Memory, and Representations of the Past
This lecture will launch of the Vice Chancellor’s Lecture Series on Trauma, Memory and Representations of the Past. It forms part of a five-year research project led by Prof Pumla Gobodo-Madikizela, funded by the Mellon Foundation. The event is hosted by the UFS Trauma, Forgiveness and Reconciliation Studies.

“One of the most remarkable aspects of trauma,” Prof Gobodo-Madikizela says, “is the loss of language, a moment of rupture that produces what some scholars have referred to as ‘speechless terror’. The arts, in all its forms – literary, performance, and visual – are a viable mechanism through which the unspeakable, traumatic past may be represented.”

These artistic forms of representing trauma are at the heart of this Vice-Chancellor’s Lecture Series. “We are interested not only in how experiences that transcend language are represented through the arts,” Prof Gobodo-Madikizela explains, “but also in probing the limits of trauma theory, and how the creative arts might be employed to bear witness in a way that may open up the possibility of healing.”

Dr Buhle Zuma
Former Mandela Rhodes scholar and one of the 2011 Mail & Guardian’s 200 Young South Africans, Dr Zuma is particularly interested in issues at the heart of our rainbow nation. His current research revolves around the question of freedom: what it means to be human for black people after centuries of dehumanisation, and the role of desire and fantasy in the political imagination of post-apartheid South Africa.
