As your departmental scribe, I have had the privilege of experiencing this department from many angles, first as an undergraduate student, then as a postgraduate, later as a lecturer, and in that time, I have witnessed five brilliant heads of department, the growth of our institute from IPB to  IPBB, and the department’s continued rise as a hub of excellence. What an exciting time to be part of the Faculty of AgriSciences and to celebrate 100 years of Genetics at Stellenbosch.

Friday, 8 August marked a significant milestone for our 2025 Honours students in the Department of Genetics and the  the Institute for Plant Biotechnology and breeding  (IPBB) programme. After completing an intense six-month series of theory modules, they took their first bold step into the laboratory phase of their academic journey, presenting their project proposals to staff, postdoctoral fellows, and fellow students.

The Genetics and IPBB Honours groups presented  their work in different venues:

In the Genetics Department’s Seminar Room, the flash presentations  spanned an impressive range of topics, from important crops such as grapevine, wheat, raspberries and detection protocols in Candidatus, to aquaculture research on dusky kob, and studies on other species like guitarfish. Presentations also covered human genetics,  including the pathogenesis of ageing and Obsessive-compulsive disorder (OCD)  and animal genetics, featuring work on snakes such as the Gaboon viper.

Meanwhile, in the Natural Sciences Building, the IPBB students took a different approach. Standing beside their posters like custodians of their research, they engaged curious audience members who stopped by. Instead of timed flash talks, they offered concise, on-the-spot explanations, creating an interactive and conversational atmosphere around their work. Their research topics were just as diverse,  from alternative protein sources for food, beans, and marula oil, to salinity stress in Thinopyrum distichum, phenomics, sugarcane, potatoes, and coffee.

I attended both venues, and both buzzed with energy as staff and postdocs circulated, posing challenging questions and offering guidance to sharpen research objectives. Despite the differences in format between IPBB and Genetics, one thing was certain: the research was solid, and the creativity in both scientific ideas and poster designs was evident.

“This is where the real work begins,” one staff member remarked. “They’ve done the groundwork ,  now they get to apply it, experiment, and  discover.”

As your departmental scribe, I can’t help but reflect on my own Honours journey at IPBB. Thus can I say; In science, the pursuit is rarely a straight path to the “next big discovery.” More often, it is a gradual awakening,  a process of finding your rhythm, learning to think with both precision and creativity, and allowing the questions to shape you as much as you shape the answers.

The months ahead will test patience and persistence with long hours in the lab, relentless data analysis, and challenges that seem insurmountable. Yet, within those very moments lies the quiet thrill of discovery  not just of new knowledge, but of the scientist you are becoming!

Goodluck!

On March 26, 2025, the Department of Genetics proudly celebrated the graduation of ten MSc students and two PhD candidates, In the lead-up to graduation, each student conducted rigorous research and as part of the academic requirements, students were required to deliver a formal 20-minute defense presentation to the department. These sessions were attended by academic staff, fellow students, and, in some cases, supportive family members. Following each presentation, an examination panel engaged the candidates with in-depth questions designed to assess their scientific understanding, methodological rigour, and critical thinking. The process concluded with a panel deliberation to determine the outcome, making this not only a celebratory milestone but also one earned through a highly demanding and scholarly process.

Under the supervision of Prof Johan Burger and Dr Manuella Campa, two students led projects that contributed to the advancement of plant molecular biotechnology. Mr. K Kruger explored the use of RNA interference to induce GVA virus resistance in Nicotiana benthamiana, offering insights into viral control strategies in crops. Meanwhile, Mr. P Bosman investigated virus-induced genome editing in wheat, developing a novel system for gene-editing delivery, an exciting leap forward in functional genomics.

Mr Willem Botes, head of the Plant Breeding Laboratory, supervised two students working on wheat improvement. Ms. KJ Holster applied high-throughput markers to identify yield-related traits, strengthening the department’s role in pre-breed

ing for food security. Ms. M van der Hoven contributed important data on pollen-mediated gene flow in wheat and related species, supporting biosafety frameworks in breeding programs.

Dr. Marlon-Schylor le Roux supervised Mr. D Allsopp, whose work focused on the Serpin-Z2B gene in common bread wheat under drought stress. This research deepened our understanding of stress response mechanisms in cereals and highlighted potential genetic targets for genetic engineering for enhancing drought tolerance.

Within marine and conservation genetics, Prof Aletta Bester-van der Merwe supervised Ms. K Redelinghuys, whose research examined the evolutionary connectivity of whiprays across the Southwestern Indian Ocean, a study with significant implications for marine conservation management. Prof Clint Rhode supervised Ms. M Roux’s research which was focused on genome-wide characterisation of repetitive elements in the dusky kob, contributing to our genomic knowledge of this ecologically and economically important species.

In forestry genetics, Ms. G Dyer, under the guidance of Dr. Paul Hills, developed a laboratory protocol for the in vitro micropropagation of hybrid Pinus patula × Pinus tecunumanii. This work adds practical value to clonal propagation techniques in commercial forestry.

The medical genetics track was represented by Ms. M Collins, supervised by Dr Brendon Pearce, who investigated mitochondrial DNA mutations linked to intervertebral disc degeneration. This research offered important insights into the molecular basis of spinal disorders and the future of personalised medicine.

From the Institute for Plant Breeding and Biotechnology (IPBB), Mr. B Moodley completed a project under the leadership of Dr Shuan Peters, focusing on the functional role of late embryogenesis abundant (LEA) proteins in drought tolerance in sugarcane, a crop vital to southern Africa’s agricultural economy.

The department also proudly celebrated the graduation of two PhD candidates:

Ms Jessica Vervalle, supervised by Dr. Justin Lashbrooke, completed her PhD on the molecular mapping of fruit quality traits in grapevine, advancing our understanding of key genetic loci associated with fruit development and composition. Her research, recently published in the Journal of Experimental Botany, provides important insights to support breeding programs aimed at enhancing fruit quality in viticulture.

Mr Carel van Heerden, supervised by Prof Johan Burger, focused his PhD research on the genetic analysis of downy and powdery mildew resistance in grapevine, offering a comparative study between the ‘Regent’ and ‘Red Globe’ cultivars. His work makes a significant contribution toward breeding grapevine varieties with improved disease resistance, a crucial step for sustainable and resilient crop production.

Each graduate journeyed through a robust and supportive academic environment, emerging not only as subject matter experts but also as skilled critical thinkers and problem-solvers. Some will take their expertise and ingenuity to industry, research institutions, and policy development by entering the workforce, while others will continue to hone their academic careers through doctoral studies. The Department of Genetics applauds their achievements and looks forward to following the remarkable contributions they will continue to make in advancing the field of genetics both locally and globally.

The Department of Genetics at Stellenbosch University proudly welcomes Prof. Clint Rhode as its new Chair. A distinguished researcher and academic leader, Prof. Rhode brings a wealth of expertise in genetics, making his appointment a significant milestone for the department as it continues its 100-year legacy of research and education excellence.

With a PhD in Genetics, Professional Natural Scientist registration (SACNASP Reg. No. 400139/15), and as President of the South African Genetics Society (SAGS), Prof. Rhode has established himself as a leading figure in the field. His research focuses primarily on animal genetics, with a specialisation in population and quantitative genetics, disciplines that are critical for advancing breeding programmes and understanding complex genetic traits.

A Passion for Science and Leadership

Reflecting on his journey into genetics, Prof. Rhode shared how his early curiosity and love for science shaped his career path.

“I was always curious, always asking ‘why.’ Initially, I wanted to be a veterinarian but soon realised that I needed a career that allowed for constant discovery. Genetics fascinated me because it combines mathematics and biology—two things I truly enjoy. That’s how I found my way into the field.“

Despite his casual recounting of this journey, behind his words lies an exceptional academic record; having earned cum laude for all his degrees. His humility stands out as a defining trait, despite his remarkable achievements. When asked about his vision for the department, he speaks with certainty and purpose. His primary focus is on strengthening the department’s academic community and research excellence, particularly in the wake of post-pandemic challenges.

“One of my key goals is to foster an environment where researchers and students feel connected, inspired, and part of something greater than themselves.”

Stellenbosch University’s Department of Genetics is one of only two independent genetics departments in South Africa, allowing students to obtain postgraduate degrees in genetics as a standalone discipline. While many universities have merged genetics with biochemistry or microbiology, Stellenbosch remains committed to training specialists in genetics rather than general biologists; a responsibility that Prof. Rhode is passionate about maintaining.

Opportunities and Challenges in a Changing Field

Prof. Rhode describes the department’s opportunities and challenges as a “double-edged sword.” While adapting to change is necessary, it also presents a unique opportunity to rethink how the department operates and stays at the forefront of scientific advancements.

“Change management is always a challenge, but it also allows us to reassess our direction and remain relevant in a rapidly evolving field. The key will be ensuring that everyone understands the importance of these changes and how they contribute to our long-term success.“

His commitment to innovation is evident, ensuring that the department continues to be a leader in genetics research, education, and industry collaboration.

Groundbreaking Research in Genetics

Prof. Rhode’s contributions to genetics extend beyond the lecture hall. One of his most significant research projects was sequencing the first and only genome of South African abalone (perlemoen, as it is locally known), a species that plays a crucial role in aquaculture and marine conservation.

“By understanding the abalone’s genetic makeup, we can find ways to help them grow faster, protect their populations, and ensure they can survive as ocean conditions change due to climate shifts.”

Additionally, his research on the black soldier fly, a species with major applications in sustainable animal feed and waste reduction, has gained international recognition. His work explores how genetics influences large-scale breeding programmes, enhancing food production in an efficient and environmentally sustainable way.

A testament to his growing influence in the field, Prof. Rhode was recently invited as a keynote speaker at the Insect Genetic IMProvement, IMPlementation, and IMPact (Insect-IMP) workshop in Athens, Greece. Delivering a plenary session on “Population and Functional Genomics of Black Soldier Fly Mass Rearing,” he not only showcased his expertise, but also represented Stellenbosch University and Sub-Saharan Africa on the global stage. This prestigious invitation reaffirmed his standing as a leader in applied genetics, further highlighting the department’s role in pioneering research that addresses real-world challenges in food security and sustainable agriculture.

Empowering Learners, Students, and the Next Generation of Scientists

Beyond research, mentorship and student engagement remain central to Prof. Rhode’s academic philosophy. He firmly believes that students are the department’s ambassadors, shaping its reputation and impact.

“Our role as academics isn’t just to teach; we need to inspire. Students go out into the world as our ambassadors, proving why genetics at Stellenbosch University is world-class.”

For young learners considering a career in genetics, he highlights the increasing importance of computational skills and adaptability in today’s fast-changing scientific landscape.

“Genetics is evolving rapidly. If you enjoy biology but also have an interest in statistics, AI, and computing, this field is for you. It’s where the future of medicine, agriculture, and biotechnology is being shaped.”

Beyond the Lab

Outside of academia, Prof. Rhode has a creative side that may come as a surprise. He is an avid cook and amateur mixologist, treating the kitchen as his personal lab. Known for his signature chocolate brownies, lamingtons, banana muffins, and cinnamon rolls, which, according to him, are better than Cinnabon’s, he laughs as he shares how his passion for cooking ties back to his love for science.

“I don’t get much time to do experiments in the lab these days, so I experiment in the kitchen instead!”

Despite his demanding role, he values solitude and reflection, setting aside Sundays as his ‘Day of Solitude’ for personal growth and relaxation. When asked what most people don’t know about him, Prof. Rhode shared an unexpected answer: he considers himself an introvert at heart.

“Public speaking and leadership roles were not something that came naturally to me. I had to grow into them over time. But while I’ve learned to embrace these aspects of my career, I still cherish the quiet moments where I can just be, well… Clint.”

Looking to the Future

With the department celebrating its centenary, Prof. Rhode sees this as both a moment for reflection and a time to set ambitious goals for the future.

“It’s a time to celebrate our past achievements while also preparing for the next 100 years. How do we stay relevant? How do we keep pushing the boundaries of genetics? These are the questions that will guide our future.“

As the department embarks on this exciting new chapter, students, staff, alumni, and collaborators are invited to participate in the upcoming centenary events and engage with the department’s latest research initiatives and academic developments.

A Homegrown Leader with a Bold Vision
