From curiosity to contribution: A PhD journey in Plant Stress Biology

08 April 2025 | Story Precious Shamase | Photo Kaleidoscope Studios

Sellwane Moloi — Sellwane Jeanette Moloi celebrates graduating with a PhD in plant stress biology, contributing vital research toward global food security through drought-tolerant wheat studies.

Embarking on a PhD is a transformative journey, one filled with intellectual challenges, personal growth, and the potential to contribute meaningfully to one's field. For Sellwane Jeanette Moloi – who has graduated with her PhD on Friday 4 April during the afternoon session – the path was illuminated by a deep fascination with plants and a determination to address the critical issue of global food security.

A spark of curiosity

"The initial spark came from a deep curiosity about plants," Moloi shared. "I was intrigued by how plants function and the key mechanisms that help them survive when exposed to various environmental stress factors. Learning different techniques used to study and analyse plant responses to environmental factors made me even more intrigued." This curiosity fuelled a rigorous exploration into plant stress biology, focusing on how wheat thrives under drought conditions.

Navigating the challenges

Reflecting on the experience, however, the PhD journey was not without its hurdles. "One of the most challenging aspects was staying motivated and managing pressure," Moloi confessed. "Setbacks and slow progress can also be overwhelming." Overcoming these obstacles required a strategic approach: "I had to break down larger tasks into manageable tasks and also seek support from my supervisors."

Doubts inevitably arose, especially when experiments did not go as planned. "There were moments when I asked myself what I had actually gotten myself into," she admitted. However, the unwavering support of supervisors, colleagues, friends, and family provided the necessary reassurance. "They always assured me things would work out; I needed to hang in there."

Key discoveries and achievements

Amid the challenges, significant discoveries were made. Notably, Moloi found that a drought-tolerant wheat variety suppressed photosynthesis as a potential strategy to avert oxidative stress damage, maintaining cell membrane integrity during stressful conditions. This unexpected turn stressed the complexity of plant survival mechanisms.

Moloi’s dedication and hard work culminated in significant achievements, including winning the best PhD poster in plant physiology at the 46th South Africa Association of Botanists Conference in 2020, 3rd Prize at the University of Johannesburg Postgraduate Symposium in 2023 and publishing two research articles in high-impact journals. These accomplishments are a testament to her research prowess and contribution to the field.

Developing essential skills

Beyond the research itself, the PhD journey fostered critical skills vital for future success. ‘Critical thinking, logical reasoning, and problem-solving’ were highlighted as key takeaways. "As a PhD student, your mind is constantly engaged in critically analysing results and providing logical reasoning. I believe these skills are valuable in tackling certain situations and providing solutions to problems."

Balancing life and research

Balancing research with other aspects of life proved challenging. "That was challenging, but I created a schedule that worked for me," the graduand explained. "This included dedicating certain days (weekends or holidays) or hours to specific tasks, such as lab work or writing. One thing I would advise a PhD student is that they should make time to rest to avoid burnout."

Contribution to food security

Moloi's research holds significant implications for global food security, a pressing issue in the face of climate change and a growing population. "I hope my research will provide insight into how wheat as a cereal crop thrives under drought stress conditions, and the information can be used by plant breeding initiatives in developing more drought-tolerant crops," she stated. "The opportunity to contribute to the field of plant stress biology – my research focuses on understanding plant response mechanisms under drought, and acquiring such information can address issues related to global food security."

Advice for future PhD candidates

For students embarking on their PhD journey, Moloi offered valuable advice: "This degree requires one to be highly motivated and ask for help whenever there are setbacks. There will always be setbacks in research; you need to go back to the drawing board and look for solutions." She also emphasised the importance of seeking support for mental and emotional well-being. "It is okay to feel overwhelmed; the work can be too much at times. Students need to ask for help. We have professionals on campus who can assist with mental or emotional issues."

Furthermore, Moloi shared personal lessons: "Time management and prioritising important tasks. I also learned that it is important to allow yourself to rest. This degree can affect your mental or emotional health." And a candid reflection: "I did not have much of a social life, and I spent most of my time in the lab."

Looking ahead

With a PhD in hand, Moloi aspires to become an expert in her field, collaborating with other researchers and mentoring future students. Her journey exemplifies the dedication, resilience, and intellectual curiosity required to excel in academia and contribute to addressing pressing global challenges.

The university provided essential support throughout her studies, ensuring access to facilities even during the COVID-19 pandemic. "I always had access to the facilities on campus to do my research, even during the COVID-19 pandemic."

Celebrating milestones along the way was crucial, with fellow postgraduates sharing in each other's achievements. "My fellow postgraduates and I often went out for lunch to celebrate everyone's achievements." And the support system was extensive: "Everyone – family, supervisors, friends, and colleagues.”

Getting out of the dark

Since 2008, the University of the Free State has been busy with the planning and implementation of projects to reduce the impact of load shedding. To date, the cost of these projects has run to R6 million. They have been done primarily to ensure that the academic programme does not suffer damage as a result of the increasing interruptions in the power supply that are continuing this year.

The university’s greatest concern has been the provision of emergency power to the lecture halls and laboratories.

Thus far, 35 generators are servicing 55 buildings on the three campuses of the UFS. This includes 26 generators on the Bloemfontein Campus, eight on the Qwaqwa Campus in the Eastern Free State, and one generator on the South Campus in Bloemfontein. The generators are already in service, and are maintained in working order.

Since 2010, the university has also ensured that all newly-built academic buildings are equipped with emergency power supplies.

On the South Campus in Bloemfontein, the new lecture-hall building and the computer laboratory are equipped with emergency power, while the installation of emergency generators in other buildings is under way. The majority of the buildings on the Qwaqwa Campus in the Eastern Free State are equipped with emergency power supplies.

In the meantime, the UFS management has approved a further R11 million for the installation of additional generators on the three campuses. A further R1.5 million has also been approved for the purchase of two mobile generators.

To extend the work already done, the main task will be the installation of more generators on the Bloemfontein Campus to ensure that lecture halls with emergency power will be available for the centrally-arranged timetables, and to ensure that more of the critical laboratories will be provided with emergency power.

There are still some important buildings and halls on the Bloemfontein Campus that must be supplied with emergency power. However, it is a costly process and must be brought into operation gradually. The further implementation of emergency power depends on the delivery of equipment. The university is also investigating alternative solutions for power provisioning, including solar power.

Generators with spare capacity are optimally deployed to satisfy the lower needs of the campus, including the Odeion, the ANNEX at Microbiology, the Stabilis ANNEX, the Agriculture Building, the UV-Sasol library, and the Francois Retief Building.

In addition, the UFS is busy on all campuses, coupling area lighting, including

street lights and pedestrian walkways, to existing generators. Procedures for the operation of mechanical equipment, such as entrance gates, lifts, and so on, are currently being dealt with on all campuses. Continuous power sources for certain ICT equipment will be installed on all campuses to protect it against power surges.

Staff and students can also equip themselves with the necessary knowledge to manage load shedding in their specific areas of work and study. It is always helpful to know who to contact. The following list with guidelines and contact numbers has been compiled to assist you:

1. In an emergency, call Protection Services. This line will continue to operate, regardless of whether the power is on or off.
2. Avoid using lifts just before planned load shedding. Some lifts have emergency power packs which will bring the lift to the nearest floor and open the doors. If you still get stuck in a lift during a power outage, use your cellphone to call Protection Services. While you're waiting, stay calm and be patient.
3. If the access control systems in your building stop working after load shedding, contact Protection Services.
4. The students and staff members who are most at risk during load shedding are those in wheelchairs or with other mobility limitations. As far as possible, plan ahead to avoid being stuck on a floor or in a room that is difficult to access when load shedding is imminent. Please contact Protection Services if you need assistance.
5. During a fire, alarms WILL go off. Alarms are not power driven, but battery driven. For assistance, contact Protection Services.
6. The main UFS Switchboard (Bloemfontein Campus +27(0)51 401 9111 and Qwaqwa Campus +27(0)58 718 5000) will continue to operate during load shedding.

Contact details of Protection Services:

Bloemfontein Campus: +27(0)51 401 2634/2911
Qwaqwa Campus: +27(0)58 508 5460/5175
South Campus: +27(0)51 5051217

Communication and Brand Management will make information available on the UFS web, Facebook page, Twitter, Blackboard and the intranet. Get the load shedding schedule from Eskom’s webpage (http://loadshedding.eskom.co.za/). The Bloemfontein Campus falls in group 4 and the South Campus falls in group 2 in Centlec’s load shedding schedule.
