The Department of Genetics at Stellenbosch University is home to a vibrant and diverse academic community of 23 staff members whose research spans the full spectrum of genetics from plants and animals to human health. Closely integrated into this ecosystem is the Institute for Plant Breeding and Biotechnology (IPBB), a leading centre for innovation in molecular biology, genetic engineering, and applied breeding. Together, these groups contribute to a rich, interdisciplinary research environment with a global reach.

As the departmental scribe, I’ve long wanted to capture the remarkable breadth of research taking place across our community. This year, I invited colleagues to share highlights from their research programs milestones that reflect not only the depth of their work but also its international relevance and collaborative nature. What follows is a curated snapshot of several academics whose work continues to expand the department’s global footprint:

Prof. Anna-Maria Botha-Oberholster, a full professor in the Department of Genetics, is a highly accomplished researcher whose work in plant genomics has consistently bridged fundamental science with real-world agricultural applications. She is a B-rated scientist by the National Research Foundation and one of the department’s most cited academics, with over 5,800 citations, an h-index of 39, and more than 150 peer-reviewed publications this exclude her extensive list of patents, reports and book chapters. Her research has been instrumental in shaping the scientific understanding of host-pathogen dynamics and functional plant biology.

In 2025, she co-authored the article “Evaluating long-read assemblers to assemble several Aphididae genomes,” published in Briefings in Bioinformatics. This study evaluated genome assembly tools for agriculturally important aphid species, contributing valuable genomic resources for the field. However, she has also co-authored two review papers: “Russian wheat aphid: A model for genomic plasticity and a challenge to breeders,” and “Unlocking Wheat Drought Tolerance: The Synergy of Omics Data and Computational Intelligence,”

Her international profile is further strengthened by her role as the South African partner in the EU-funded NATUREBIOPROMO project, part of the Biodiversa+ and Water4All initiatives. This four-year collaboration brings together scientists from Portugal, Brazil, Italy, the Czech Republic, and South Africa, aiming to develop nature-based biotechnological solutions that reduce pesticide dependence while promoting agricultural sustainability. The project focuses on harnessing beneficial plant microbiomes and natural bioactives to improve crop health and resilience. Prof. Botha-Oberholster’s involvement ensures that African biodiversity and research perspectives are meaningfully included in this international dialogue on ecological innovation and food security.

She leads a dynamic research team composed of Dr. Hendrik Swiegers (postdoctoral fellow), a dedicated bioinformatician / technical officer (Dr F Burger), and a cohort of postgraduate students. Her group specialises in host-pathogen genomics, functional biology, and systems-level approaches to plant defence. With a long-standing reputation for mentorship, collaboration, and high-impact science, Prof. Botha-Oberholster remains one of South Africa’s most respected figures in agricultural molecular sciences.

Prof. James Lloyd, a C-rated scientist and a associated professor based at the Institute for Plant Biotechnology and breeding  (IPBB), has long been at the forefront of plant metabolic engineering. With over 3,900 citations, an h-index of 28, and +43 publications, his research continues to shape both theoretical and applied aspects of plant biotechnology, particularly in starch metabolism.

His most recent article, accepted in Biotechnology Journal, is titled “Simultaneous Repression of GLUCAN WATER DIKINASE 1 and STARCH BRANCHING ENZYME 1 in Potato Tubers Leads to Starch with Increased Amylose and Novel Industrial Properties.” This study investigates how post-transcriptional gene silencing of two key starch-modifying enzymes (SBE1 and GWD1) alters the physical and chemical structure of potato starch. The results revealed increased amylose content, altered granule morphology, and changes in viscosity all of which hold promise for creating tailored starches with enhanced industrial applications. The research provides a compelling in planta strategy for designing healthier, functionally optimized storage starches.

In support of this work, Prof. Lloyd was awarded a three-year NRF Rated Researcher Grant titled “Making potatoes resistant to virus attack and healthier to eat using genome editing.” The project uses CRISPR technology to confer resistance to potato virus Y (PVY) while also engineering the tuber starch to be both less digestible h  elping reduce the risk of type II diabetes and lower in acrylamide formation during frying. The project is a collaborative effort involving Dr. Manuela Campa, Prof. Johan Burger (both Stellenbosch University), and Dr Zanele Mdodane (North West University) , and reflects a strategic blend of nutritional, health, and agricultural goals. Prof. Lloyd’s research demonstrates how fundamental molecular biology can be harnessed to address real-world challenges ,advancing food safety, crop durability, and industrial processing all within a single framework.

Prof. Aletta Bester-van der Merwe  an associated Professor plays a leading role in marine conservation genetics and is a cornerstone of the department’s internationally recognized work on elasmobranch (shark and ray) population dynamics. With an h-index of 22, i10-index of 40 and +70 publications , she continues to be a high-impact researcher shaping the field of marine molecular ecology and conservation.

Among various national and international consortiums Prof. Bester-van der Merwe is a key member of the COEXISTENCE project (2025–2028), which investigates socio-ecological conflicts between fisheries and marine megafauna, including sharks and toothed whales, in the South West Indian Ocean. As part of the South African team, alongside Prof. Peter Teske, she contributes genetic insights, which focuses on genetic connectivity in the Mozambique Channel. Her role involves identifying conservation units through advanced population genomics, supporting evidence-based strategies for transboundary marine biodiversity protection. The project, coordinated by Dr Paul Tixier (IRD, France), includes partners from France, Mozambique, Madagascar, the Comoros, and South Africa, emphasizing Aletta’s international research leadership in complex, multi-jurisdictional systems.

Prof. Bester-van der Merwe leads a thriving research group, supported by a network of postgraduate and postdoctoral researchers. In her 13 years as a principal investigator, she has supervised and co-supervised 10 PhD, 15 MSc, and 25 Honours students. Her current postdoctoral fellows, Dr Juliana Klein and Dr Michaela van Staden are actively engaged in the Shark and Ray Genetics laboratory under her mentorship, contributing to foundational and applied research in marine conservation genetics.

Dr. Nathaniel McGregor,  a senior lecturer in the department, is making substantial contributions to global psychiatric genetics through internationally collaborative research. With over 2,200 citations, an h-index of 17, and +21 publications, Dr. McGregor’s academic footprint reflects the depth and relevance of his work within the mental health genetics field.

In 2025, he co-authored two publications that deepen our understanding of the genetic basis of complex mental health disorders. His first, published in Biological Psychiatry, is titled “New Genomics Discoveries Across the Bipolar Disorder Spectrum Implicate Neurobiological and Developmental Pathways”. This large-scale review, published ahead of print, synthesizes findings from the Psychiatric Genomics Consortium and highlights emerging signals linked to bipolar disorder subtypes, and provides insights into the neurobiological and developmental pathways previously uncharacterized for this disorder.  These new findings hold promising implications for treatment options.

His second and arguably most prominent contribution is as co-author of a landmark paper in Nature Genetics, titled “Genome-wide analyses identify 30 loci associated with obsessive–compulsive disorder (OCD)”. This genome-wide association meta-analysis combined over 53,000 OCD cases and more than two million controls, identifying 30 significant loci and over 249 effector genes. The study reveals that approximately 90% of OCD heritability is polygenic and involves excitatory neurons in the hippocampus and cortex.  These findings, along with validation of the utility of advanced molecular methodologies such as  fine-mapping, and the use of polygenic risk scores to improve statistical power in complex disorders studies offers a foundation for follow-up studies, including functional work. Together, these publications reflect Dr. McGregor’s integral role in globally networked psychiatric genomics and reinforce the department’s growing presence in large-scale, international research consortia.

Dr. Christell van der Vyver a lecturer and a C2-rated scientist is contributing significantly to South Africa’s biotechnology landscape through impactful academic research and strategic industry partnerships, particularly in the field of sugarcane improvement. With over 800 citations, an h-index of 16, and +30 publications, her scholarly record demonstrates both depth and sustained influence within applied plant biotechnology.

She recently secured a two-year industry contract with ABF SUGAR (PTY) LTD, a global sugar leader with operations across ten countries, including Southern Africa. The project focuses on genetically modified sugarcane lines engineered to express the Cry51Aa2 protein; a modified insecticidal gene with the potential to offer resistance against the yellow sugarcane aphid (YSA), a serious regional pest. Ongoing contracts also include an agreement with the South African Sugar Association (SASA), focusing on the establishment of modern gene editing technologies for sugarcane.

In 2025, Dr. van der Vyver also authored two peer-reviewed publications that advance sugarcane genomics and stress resilience. Her first article, published in Physiologia Plantarum, titled “Comparative Transcriptomic Analysis of AtBBX29 Transgenic and Wild Type Sugarcane Exposed to Drought Stress”, provides new insights into the molecular mechanisms underlying drought tolerance in genetically modified plants. Her second, an invited review published in In Vitro Cellular & Developmental Biology Plant, titled “Sugarcane (Saccharum spp. hybrids) Biotechnology Research in South Africa”, offers a comprehensive overview of the country’s sugarcane biotechnology advances, tracing progress from early cultivar development to recent genomic breakthroughs. Together, these outputs emphasize Dr. van der Vyver’s leadership at the intersection of fundamental research and practical agricultural impact.

Dr. Marlon-Schylor Le Roux, a rising academic in the department, is gaining recognition for his innovative work at the intersection of molecular biology, artificial intelligence, and sustainable agriculture. Although still early in his academic career having held his position for just four years, Dr. Le Roux has already surpassed 102 citations, with +8 publication, showing  the growing visibility and relevance of his research contributions.

In 2025, he co-authored a comprehensive review titled “Russian wheat aphid: A model for genomic plasticity and a challenge to breeders”, which examines the evolutionary flexibility of Diuraphis noxia, a globally significant cereal pest. The article offers both a historical and molecular perspective on the pest’s ability to overcome host resistance and control methods, positioning it as a model organism for studying virulence and genomic adaptation.

He also led a publication titled “Unlocking Wheat Drought Tolerance: The Synergy of Omics Data and Computational Intelligence”, published in Food and Energy Security. This work addresses the urgent challenge of climate-induced yield loss in wheat and promotes the use of AI, particularly deep learning, to extract meaningful insights from omics datasets. The article advances the case for computational tools in identifying and deploying drought-resilient traits in crops.

Dr. Le Roux’s research team consist of 5 members and his research leadership is further supported by three competitive research grants secured for 2025. The first, under the DSI High-End Infrastructure Programme (Phenomics Subfunding), supports a project on artificial intelligence, phonomics and molecular adaptation in commercial beans. He also holds an NRF Thuthuka grant to develop a CRISPR-based genome editing platform targeting stress resilience in cereal crops. In addition, he secured postdoctoral funding that enabled the appointment of Dr. Nadia Fisher-Smith, extending the research capacity of his program.Together, these achievements reflect Dr. Le Roux’s growing role in leading data-driven, future-facing crop improvement strategies with strong relevance for African agriculture and global food security.

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

As your departmental scribe, I have witnessed Prof. Rhode’s journey from PhD student to Postdoctoral Fellow, Lecturer, Senior Lecturer, Professor, and now Head of Department. As a homegrown leader, he possesses an in-depth understanding of the department’s inner workings and is uniquely positioned to build on its legacy. I look forward to seeing how his vision will shape the future of genetics at Stellenbosch University.

As the year draws to a close, the familiar rhythm of academic life begins to soften. Laboratories hum quietly as annual cleanups commence, with the faint smell of ethanol lingering as surfaces are meticulously decontaminated. The Genetics Department; a hub of scientific innovation, surrounded by the brilliant purple blooms of jacaranda trees—finds itself in a moment of reflection. 2024 has been a challenging year, yet as the staff gathered for their final academic meeting, the air was thick with the sense of reward that comes from perseverance.

After discussing strategic plans for 2025, finalizing grant reports, and providing postgraduate students with feedback on their theses in preparation for March graduations, it was time to embrace an annual tradition: the year-end lunch at Le Pommier Wine Estate. Seated outdoors under the dappled shade of umbrellas, a light summer breeze carried the scent of oak barrels and blooming flowers, setting the perfect tone for the afternoon. The lively chatter at the long, communal table reflected the camaraderie that binds the department. Glasses of Le Pommier’s house wine clinked in celebration, not only of the year’s accomplishments but also of the relationships and shared experiences. Conversations flowed effortlessly, from tales of international conferences and innovative teaching methodologies to the joys of family life and cherished pets. Even amidst the intensity of academia, it was a reminder that at its core are people—passionate, curious, and deeply human.

The Head of Department (HOD) Mr Willem Botes, rose to deliver a heartfelt speech. With a mix of pride and poignancy, he recounted the department’s achievements over the year and highlighted that the success of any academic department is rooted in teamwork. He extended heartfelt gratitude to Thanja Alison and Morney Engelbrecht, whose dedication as the department’s management and secretary ensured the smooth functioning of operations throughout the year. Their contributions were met with warm appreciation from all present.

Mr. Willem Botes then re-introduced the incoming HOD, Prof. Clint Rhode, a moment met with cheers and applause as staff eagerly welcomed the promise of fresh ideas and visionary leadership. Yet, the mood turned wistful as he paid tribute to Prof. Louise Warnich, who, after decades of groundbreaking research and steadfast leadership, was bidding farewell upon her retirement.  Professor Warnich’s farewell speech was inspiring. She reflected on the early days of her career when genetic experiments were painstakingly slow—DNA plasmid isolations that took five days, compared to today’s hours-long processes. Her journey, from lecturing Genetics 344 to becoming a professor, HOD, and ultimately Dean of Science, left us all in awe. As she spoke, the table fell silent. Throats tightened, and a few discreetly wiped their eyes. Her legacy, both as a scientist and as a mentor, was undeniable. “It’s been an honor,” she concluded, her voice steady but her emotion evident, “to watch this department grow and flourish.” The staff raised their glasses in a heartfelt toast—to the past, the present, and the future.

This wasn’t just a lunch; it was a celebration of resilience, an ode to the bonds of community, and a moment to honor the legacies that have shaped the department. As the staff departed, the weight of the year seemed somewhat lighter, replaced by the buoyancy of hope and gratitude.
