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.”

UFS responds on the outcome of the court case in the alleged attack by Cobus Muller and Charl Blom on Gwebu

2014-09-09

The management of the University of the Free State (UFS) acknowledges the finding issued on 4 September 2014 by the South African Human Rights Commission (SAHRC) that it was “unable to find any corroborating evidence to make a conclusive finding of racism and violation of human rights” in the Muzi Gwebu case.

The university management also takes cognisance of the ruling in the Bloemfontein Regional Court by Regional Magistrate Rasheed Matthews today (9 September 2014) that both Cobus Muller and Charl Blom are found not guilty on all the charges which included reckless driving, crimen injuria, attempted murder and assault (Muller), and a charge of assault (Blom). We note the Magistrate’s concerns about “inconsistencies in the evidence and exaggerations”, that the complainant “displayed hostility throughout the trial” and that he was “not a reliable witness and is prejudiced.” And therefore, in the words of the Magistrate to the defendants, “I’ve decided to give you the benefit of the doubt.”

Both Muller and Blom were suspended from all campuses of the UFS on 19 February 2014 based on the evidence available at the time of reckless driving, assault and other charges. This evidence was further borne out by an internal investigation into the incident of 17 February 2014 on the Bloemfontein Campus. In the light of the evidence available to us at the time, and the volatile situation on campus in the days following the attack, the UFS management believes that it was the correct decision to suspend the students, given the serious nature of the charges, and pending a decision of the courts.

In the light of both the SAHRC ruling as the Regional Court ruling, the university management has decided to take the following steps:

1.   The suspensions of both Muller and Blom from all campuses of the university are lifted with immediate effect.

2.   Muller may attend a forthcoming graduation ceremony during which the degree BSc Construction Management will be officially conferred upon him. He completed all the requirements for the degree in 2013, but was not allowed to attend the graduation ceremony of 11 April 2014 due to his suspension and the fact that the criminal charges were still pending.

3.   Blom may return to the university to complete his studies.

4.   The UFS is in discussion with the parents of one of the students and, if required, would also meet with legal counsel of the university, as well as those of students Muller and Blom to discuss any further steps given the outcome of the court case.

5.   In short, on grounds of the ruling by die SAHRC, as well as the Bloemfontein Regional Court, the university will not continue with its disciplinary action against Muller and Blom.

Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS said: “This has been a very difficult time for the university and I am pleased to record that throughout the crisis, the student body on the Bloemfontein Campus showed remarkable restraint and discipline, confirming also the broad, non-racial character of the peaceful protests that followed. Our student body has matured and our campus cultures are much more inclusive and transformed as a result of the quality and depth of student leadership over the past few years. The new Student Representative Council (SRC) is a splendid example of this – with the first black woman President (Mosa Leteane) and the first blind woman SRC student leader (Louzanne Coetzee).”

“I am pleased that the matter is now behind us and, again, we rest with the decisions of the Commission and the Courts as final,” he said.

Prof Jansen also apologised on behalf of the UFS to Cobus Muller and Charl Blom, their parents, and their families, for the disruption that the suspension brought in their lives and for the stress they had to bear during this difficult period. “For that, I am truly sorry,” he said.
