Prof Liezel Herselman Inuagural Lecture

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.

The University of the Free State (UFS) received over R200 000 for its No Student Hungry (NSH) Programme at the NSH launch dinner on Friday 23 March 2012 in Bloemfontein.

Prof. Jonathan Jansen, Vice-Chancellor and Rector of the UFS as well as founder of the NSH Programme donated R100 000 from the proceeds of his book We Need to Talk to this programme. Standard Bank also donated R30 000.

An additional amount of about R90 000 was raised by means of pledges made by guests and the auctioning of several items. These items were donated by local companies and university staff.

The No Student Hungry Programme (NSH) aims to raise funds to provide modest food bursaries for needy students and give them daily access to a balanced meal.
Prof. Jansen started the NSH programme in 2011 with the proceeds of his book, We Need to Talk.

The NSH funds more than 100 students in the hope of helping them to excel in their academic endeavours and, ultimately, to obtain their degrees.

In 2011, Prof. Jansen discovered that a significant number of students were studying without eating on a regular basis. These were often students with strong academic records but without adequate funding to sustain themselves with regular meals.

The project was established in January 2011 when the NSH Team started to develop the structure and processes of the programme. The first 100 students who were awarded the food bursaries started using their student cards for daily meals on campus on 1 April 2011.

“The No Student Hungry Campaign is not only about creating a university campus that cares. It is about creating a country where being human matters. Our students on the NSH project are amazing young people. They struggle to get by, but they have great potential and achieve good marks," Prof. Jansen said on Friday.

Prof. Jansen’s wife, Grace, and Dr Carin Buys, wife of Mr Rudi Buys, Dean of Student Affairs, volunteered to drive the programme and raise funds to address the problem. They are supported by various divisions within the university.

Students apply for the bursaries and are selected on the basis of their financial needs, good academic results, active participation in student life programmes and commitment to give something back to the community.

The raising of funds is a continuous process involving awareness campaigns, seeking of partnerships with companies and institutions and support from the general public, staff and individuals.

An agreement has been made with several food outlets/restaurants on campus who offer healthy, balanced meals to NSH students when they swipe their student cards that are funded by the programme.

At the end of the year the process is reviewed and students who still qualify are reinstated on the programme, whilst those whose circumstances have changed or are no longer in need of the bursaries, make way for new applications.

The NSH Team meets with students on a regular basis with the purpose of offering training, motivation and opportunities for personal growth and career development. Students are also expected to become involved in projects as a way of ploughing back into the community.

The goal is to expand the project annually as support for it grows.
Ms Nicky Abdinor, a clinical psychologist from Cape Town, who was born without arms and with shortened legs, provided an entertaining motivational speech at the launch. Ms Abdinor, founder of the Nicky's Drive organisation, also visited the UFS’ Unit for Students with disabilities where she delivered a talk on independence for people living with disabilities.
