Prof Liezel Herselman, Academic Head of the Department of Plant Sciences at the University of the Free State (UFS),) delivered her inaugural lecture on the Bloemfontein Campus this week (24 March 2022). The theme of the lecture was the ongoing battle against destructive cereal killers. 

With 28 years of extensive experience as a researcher, her work focuses on marker-assisted disease resistance breeding in wheat within a South African context. When she joined the UFS in 2004, Prof Herselman decided to apply her research expertise in marker-assisted breeding to the problems faced by wheat producers in the Free State and Northern Cape. The Free State is one of the major dryland wheat production areas in South Africa, while irrigation wheat is produced along the major rivers in the Northern Cape. 

Protection against fungal diseases

Concentrating specifically on Fusarium head blight (or wheat scab) and three rust diseases – leaf rust, stem rust, and stripe rust – she has done work to provide wheat plants with ‘tools’ to protect themselves against these fungal diseases.

According to Prof Herselman, there are many genes available in different wheat genotypes and related grass species that provide excellent protection against various races of these diseases. “Some of these genes provide protection or resistance from the seedling stage, while others provide resistance at the adult plant stage. We are thus aiming to combine as many of these genes as possible into a single wheat cultivar, without compromising yield and bread-making quality.”

She says the genes are combined by making crosses between resistant and susceptible cultivars or lines. Conventionally, through a time-consuming process, the incorporation of these genes is tested in the greenhouse and field by infecting plants with the disease to see which plants are resistant and which are not.

They can, however, follow the transfer of these genes to newly developed lines by applying molecular markers. Prof Herselman explains: “A molecular marker is a genomic fragment linked to the gene, which we can follow in the offspring we create from the crosses using different DNA techniques in the laboratory. This enables us to select new wheat lines that contain the highest number of resistance genes. The identified best lines are then used in further crosses and/or released as pre-breeding lines to commercial wheat breeding companies.”

Impact on food security

Her research has an impact on society by providing food security to both commercial and small-scale producers, as well as the end users of wheat (people buying bread and other wheat products). As researcher, it is also important for her to send out students to the workplace who can continue with this task in future.

Prof Herselman believes that when cultivars with fungal-disease tolerance or resistance are released and used by producers, it not only reduces the cost of spraying against diseases, but also increases yields by protecting the crop against fungal diseases. “We live in a world where the population is increasing daily, but land available for agriculture is not increasing and some areas are even lost due to urban development. Increasing yield in available production areas will thus have a positive impact on food security,” she says.

Besides contributing to the country’s food security, she takes pleasure in every aspect of her work. Although she misses the hands-on part of the work as academic head of the department and getting her hands dirty, she still enjoys managing the different research projects (from the conceptualisation phase to data analysis and publishing of results). The part she loves the most is to see the growth in her postgraduate students – from the moment they enter the laboratory for the first time until the day they walk out of the laboratory with their degrees. 

“It adds purpose to my life knowing that I have made a difference in a student’s life and equipped him or her with the necessary tools to be successful in the marketplace. Being able to share your knowledge is a gift, but with that gift comes a lot of responsibility as well. I am, however, up for the challenge,” concludes Prof Herselman.

Student Court is ready to exercise its legal power
2015-09-07

 

Student disputes at the University of the Free State (UFS) will be regulated henceforth by the Student Court that has been re-established at the Bloemfontein Campus. The Student Court will offer practical training to law students thus strengthening their theoretical knowledge to produce employable graduates.

The Student Court was launched on Friday 21 August 2015, cultivating a self-determined studentship and citizenship, of which South Africa can be proud.

Advocate Barry Roux, Oscar Pistorius’s defence attorney, Judge Lebotsang Bosielo, of the South African Supreme Court of Appeal, Profs Caroline Nicholson, Dean of the Faculty of Law, and Teuns Verschoor,  Chairperson of the UFS  Disciplinary Board, attended this auspicious event.

During his keynote address, Adv. Roux said the Student Court serves as a stepping-stone in the practice of integrity, respect, and preparedness within the law profession.

“Young professionals have a mandate to excel. No matter what, stick to honesty and the truth. If you want to be a role model and make your family proud, do more.” he advised.

Judge Lebotsang Bosielo urged students to use “the rare opportunity to practise and uphold the law with austerity.”

“You should broaden the knowledge of substantive law, law of evidence, procedural law, and the Constitution of South Africa. Opportunities such as the Student Court enable law students to strengthen the practice of theory beyond the parameters of the lecture rooms,” he emphasised.

The re-establishment of the Student Court was initiated by Lindokuhle Ntuli, Student Representative Council (SRC) member on Legal and Constitutional Affairs. The UFS Council approved the proposal for the court in 2006, but it had remained inactive since then. It was not until 2014 when Lindokuhle assumed office that the concept was revived.

“As an independent body, the Student Court is ready to exercise its legal powers with the aim of establishing a student community and a culture of student governance committed to justice, equality, and accountability,” he said.
