Dr Cornel Bender
Dr Cornel Bender received her PhD qualification at the virtual graduation ceremonies in October. The title of her thesis is: Stem rust resistance in South African wheat and triticale.

The rapid distribution of disease-causing organisms such as Ug99, a wheat stem-rust pathotype, pointed out just how vulnerable global cereal production is to disease outbreaks.

These cereals include wheat, barley, rye, oats, triticale, rice, maize, and millet and are one of the most important food sources for human consumption.

According to Dr Cornel Bender, the projected world population of 10 billion in 2057 requires a growth of more than 40% in cereal production. Wheat is grown on more hectares than any other cereal and is one of the most important sources of calories for humans. However, the growth rate of wheat yields has declined from the 1960s to the 1990s. Therefore, it is essential to increase global wheat production.

“With the regular appearance of more aggressive stem rust pathotypes in South Africa, there is a constant need to discover new sources of resistance, understand the genetic base of presently deployed sources in wheat, triticale and barley cultivars, and to manipulate the deployment of resistant sources through a more sustainable approach,” says Dr Bender.

Her PhD thesis, titled: Stem rust resistance in South African wheat and triticale, includes various fundamental aspects for the effective management of stem rust in South Africa.

Dr Bender is a Professional Officer in the Division of Plant Pathology in the Department of Plant Sciences, who received her PhD at the virtual graduation ceremonies in October.

Innovative and cost effective

Her promotors, Prof Zakkie Pretorius, Research Fellow, and Dr Willem Boshoff, Senior Lecturer in the Department of Plant Sciences, believe that she used an innovative approach to develop a cost-effective phenotyping method to select for more durable resistance types in a controlled greenhouse environment.

“In the past, results obtained from field trials used to assess adult plants for stem-rust resistance, were often influenced by abiotic factors, were seasonable in nature, expensive, and time consuming; therefore, the development of a dependable greenhouse screening system provides an important additional instrument for rust research,” says Dr Bender.

She adds that the greenhouse technique is used worldwide to screen for adult plant resistance and contribute to save time and money.

Broadening our knowledge

“Inheritance studies were undertaken to determine the genetic base of stem-rust resistance in selected South African wheat and triticale cultivars (developed from wheat/rye crosses) through seedling analysis as well as greenhouse and fieldwork,” she says.

Dr Bender believes the use and development of different resistance screening methods, the elucidation of host genetics, as well as the use of histological and microscopic methods to study early resistance responses, broaden our knowledge and understanding of stem-rust resistance in South African wheat and triticale cultivars.

Ultimately, rust researchers, grain producers, and also the general public – through access to their daily bread – will benefit from her study.

UFS School of Nursing opens new frontiers at 40
2009-11-16

The opening of the virtual facility of the School of Nursing at the University of the Free State (UFS) and a gala dinner to celebrate the School’s 40th year of existence took place on the Main Campus in Bloemfontein this week. At the opening were, among others, from the left: Prof. Jonathan Jansen, Rector and Vice-Chancellor of the UFS; Dr Oluseyi Oyedele and Ms Viona Munjeri, both from The Atlantic Philanthropies; and Prof. Anita van der Merwe, Head of the School of Nursing at the UFS.

All eyes in the nursing profession in South Africa were turned to the University of the Free State (UFS) when the School of Nursing opened a state-of-the-art virtual health training and learning facility and celebrated its 40th year of existence with a gala dinner on the Main Campus in Bloemfontein this week.

The lustrous events were attended by dignitaries from all spheres of the health-care fraternity in South Africa.

The new virtual facility, The Space, is made possible by a grant of R16 million from The Atlantic Philanthropies and R1 million from the UFS. The Atlantic Philanthropies organisation is an international philanthropic organisation that is going to inject R70 million into nursing in South African over the next four years. The initiative will enhance nursing education and step up the quality of health-care delivery in South Africa. Four major grants were made to universities in South Africa, of which the UFS is one.

With the facility at the UFS School of Nursing, nursing education is propelled into the future. Prof. Anita van der Merwe, Head of the School of Nursing, says, “The virtual learning facility is a very new way of thinking and teaching. At the moment, theory and practice are separated, as theory is often taught in the mornings, followed by practical settings later in the day. Learner nurses then also go to clinical facilities for their practicals where the quality of care is declining and human resources are a problem.

“We believe that with new technologies such as e-learning and high-tech computer-mediated equipment we can use the ‘virtual world’ to bridge the theory-practice gap in the same location.”

Prof. Van der Merwe says the project is essentially about transformation: taking a stand against stagnation in nursing education and practice and daring to be different.

In the new virtual facility nurses will have the best of three worlds – the expertise of the facilitator/educator, simulation technology, and a vast selection of on-line and off-line software, exposing them to blogs, broadcasting and enhancing computer literacy. This will attract both the new “millennial” generation, which tends to be technologically competent, as well as the older learner because of the unthreatening learning environment.

The core space will accommodate 40 to 60 students and is designed to encourage informal, collaborative learning and practice simultaneously. It will have a demarcated area for “patients” (such as advanced adult and baby patient simulators) and a “clinic space” allowing for role play.

At the gala dinner, Prof. Jonathan Jansen, Rector and Vice-Chancellor of the UFS commended nurses in South Africa for their caring role, but also expressed his concern that South African has lost its deep sense of care. South Africa is at a critical point and the country can be changed if a deep sense of care can be embedded again.

About forty nursing educators from all over South Africa attended an exploratory workshop in the facility today and the last meeting of the Forum of University Deans in South Africa (FUNDISA) also coincided with the festivities at the School of Nursing.
