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.”

Official opening ceremony of the UFS Qwaqwa Campus

2006-02-15

Official opening ceremony of the UFS Qwaqwa Campus
11th February 2006 – Multipurpose Hall

Opening Speech:
Prof. Peter A. Mbati
Campus Principal

Successfully rising to the challenges of incorporations and mergers – developing a vibrant and academically stimulating satellite campus of the University of the Free State.

Thank you Mr. Program Director and good morning ladies and gentlemen.

I wish to once again welcome all of you to the official opening ceremony of the University of the Free State QQ campus. Thank you for taking time to share with us an important date in our campus academic calendar. I bring you greetings from our Rector and Vice Chancellor Prof. Frederick Fourie.

During such occasions we try and reflect on important matters that have affected us as an institution in the preceding year, commit ourselves to specific objectives for the current year, while planning for the proceeding year.

Today I shall be talking on Successfully rising to the challenges of incorporations and mergers – developing a vibrant and academically stimulating satellite campus of the University of the Free State’.

SRC inauguration
I would like to congratulate the SRC President and the entire SRC leadership for being elected into important positions of student leadership and authority.

As a university we are proud of the quality of our student leadership on the Qwaqwa campus. I am confident that you young leaders will rise to the challenges of your office and discharge your duties with diligence and without fear or favour. That you will rise above your party affiliations and provide effective leadership to the entire student body on campus.

Leadership is complex and requires you to be objective, just and fair in your approach to the many challenges that you will encounter. You will be judged not by the populist decision that you take when confronted with difficult choices, but rather, on the wisdom that you exercise in reaching consensus in decision making processes.

The era when management and student leadership viewed each other with suspicion and as adversaries is long gone. Management, academic and administrative staff, parents and students must have common agendas in as far the quality growth and development of our university is concerned and to strive towards academic excellence. I leave the challenge to you students, and more so to the inaugurated student leaders to define your agenda in achieving this noble objective. I trust that you will make the right choices.

Brief history of incorporation
On the recommendations of the National Working Group of Higher Education, the Qwaqwa Campus of the then University of the North was incorporated into the University of the Free State on 1st January 2003. We suddenly had to move from a campus that was originally semi-autonomous and with its own culture developed over almost 20 years, into a campus that had to operate as a fully integrated campus of the UFS, a 100 year old institution with its distinct culture.

Following incorporation, we not only had to continue with our core business of teaching, learning, research and community service, but we also had to engage in other important aspects such as exploring the most appropriate models of governance for the campus, encouraging dialogue and interactions at all levels between personnel at the different campuses with a view to developing trust between colleagues. And with the added dimensions such as participation in the transformation task team we in effect are at the fore front of developing a new institutional culture at the UFS and a truly South African University.

UFS Strategic objectives
The strategic and transformation priorities of the University of the Free State for 2006 – 2008 as approved by the Executive Management at its retreat in January 2006 are:

Quality and Excellence
Equity, diversity and redress
Financial sustainability
Regional co-operation and engagement

Central to this priority is the integration of the Qwaqwa campus as a valuable constituent part of the UFS, and the strategic reconfiguration of the campus in order that the UFS can play a meaningful role in regional engagement and development.

National leadership

The five strategic objectives cannot be viewed in isolation and run simultaneously and in concert with each other.

The Question must therefore be what we on the QQ campus, staff and students, parents and our broader community are willing to do to achieve these strategic objectives. The reconfiguration and strategic planning of this campus, and therefore its success, must be a collaborative effort between colleagues at QQ and on the main campus. We must all be ready to work together, to plan together, to shoulder responsibilities together and sometimes, to share the pain and disappointments together.

The second question must therefore be: are we prepared to go that extra mile for our campus to ensure that we claim our rightful stake within the ranks of well respected academic institutions of higher learning in this country? At this point in its history this campus requires committed men and women from across the cultural spectrum who appreciate the challenges ahead of us and who are ready to give of their best and to constructively engage at all levels to make this dream a reality. Because this dream is possible and this dream will be realized!

Quality and Excellence (1st strategic objective)

As mentioned by the Rector in his speech at the official opening ceremony of the university on the main campus on Friday 3rd February, the university will in 2006 pay extra attention to Quality and Excellence. This is informed by the Higher Education Quality Committee’s (HEQC) institutional audit which is scheduled to take place this year. Our university as well as several other HEI’s will be subjected to this audit. This will call for a lot of hard work on your part in preparation for a successful audit and in this regard therefore I request for your cooperation.

As a further step in confirming our commitment to quality and excellence, we have simultaneously introduced on the QQ campus and the main campus workshops on performance management systems to a cohort group. This will be expanded in 2006 to a wider group of managers on the QQ campus to include among others all Program Heads and Subject Heads. PMS is an invaluable tool for fair, effective and efficient management of a very important resource on campus – the human resource. Benefits of PMS include among others:

Instilling and enriching a culture of performance management (quality assurance) as an integral part of the day to day functioning of staff at the campus
Improving staff performance through mentoring, development and training

Tri campus project
One of the more important projects that we as a university undertook in 2005 was the Tri Campus Project which was coordinated by the Free State Higher Education Consortium (FSHEC) through Niel Butcher and Associates consultants.

The Tri-Campus project focused on the strategic planning for higher education campuses in the Free State that have been incorporated with UFS and CUT during the reshaping of the South African higher education landscape. The Bloemfontein Vista campus and the Qwaqwa campus of the University of the North were incorporated with the UFS, and the Welkom Vista campus with the CUT.

The planning process involved a range of research and consultation activities during the course of 2005. This included:

Conducting situational analyses of the Qwaqwa campus during which staff and students were widely consulted;
Consulting with the campus and with a range of stakeholders in the sub-region
Review of the Free State Provincial Growth and Development Strategy and Integrated Development Plans (IDPs) of the regions and other research of relevance to the sub-regions, province and country.

An operational framework for the reconfiguration of the campus with a range of possible Program Qualification Mixes has been produced. In December 2005, the Rector, the Vice Rector Academic Planning Prof. Magda Fourie and I discussed this document with senior members of the DoE in Pretoria, and we will soon be meeting with the National Minister of Education Me Naledi Pandor for her guidance and to seek support in the further refinement of the document and subsequent implementation.

Recapitalization
This year a further R 6 M has been budgeted for recapitalization. In about two weeks time the third of phase of renovations on campus will commence and attention will be given to the administration building, the humanities and the outstanding work in the lecture hall complex. There- after the library, sciences and education buildings will follow. As you will recall a substantial portion of the R 8.4 million in 2005 was used to upgrade the student residences and the lecture hall complex.

I am certain that the renovations and upgrading of our infrastructure and physical facilities including landscaping will create an enabling environment for you to enjoy your work and studies on this campus.

Renovations come with some measure of inconveniences and I therefore wish to request for your patience and support during this period.

Closing remarks
There is a heightened spirit of optimism on what the future holds for this campus. This is evident when I talk to a large cross section of staff and students of this campus – and I therefore invite all of you to come and be partners with us on this journey of optimism and hope of what the future holds for the UFS – QQ campus.

Thank you and God bless!
