Damaris Barminga is a passionate molecular biology and biotechnology researcher currently serving as a research assistant and graduate fellow at Kenyatta University, Nairobi, Kenya. She is pursuing her M.S. degree in biotechnology, focusing on plant-pathogen interactions, with a particular emphasis on the parasitic plant Striga. In her recent paper published in MPMI, “Cell Wall Dynamics in the Parasitic Plant (Striga) and Rice Pathosystem,” she delves into the intricate offensive and defensive mechanisms involved in the interaction between Striga and its host plant. Her work provides groundbreaking insights into the complex molecular strategies deployed by Striga to invade its host, as well as the corresponding defensive responses of rice, paving the way for innovative approaches to combat this devastating agricultural weed.
1. What do you think is the most important or exciting finding from your paper?
In our paper, we utilized simultaneous RNA sequencing to unravel the cell wall dynamics in rice and the parasitic plant Striga. On rice, we did a comparison on the cell wall modification processes in a susceptible and resistant interaction. Similarly, a comparison of Striga infecting the two. Interestingly, the study revealed the flip side of the interaction—Striga infecting a resistant versus a susceptible rice genotype, highlighting its dual role as both a plant and a pathogen. This duality showcases an intriguing dynamic between offense and defense. A highlight of strategies such as cell wall degradation is observed as the offense plays through the induction of endo-1,3-β-glucosidase, resonating with other pathosystems during triggered immune responses.
Another exciting finding from the paper is the phenotype from the resistance assay on the rice genotype Nipponbare showed Striga wasn’t able to breach the endodermis and took a detour at the Casparian strip and exited the host root.
2. Was there a piece of data that was particularly challenging to obtain, or a part of the project that was particularly difficult?
Obtaining high-quality RNA from Striga-infected root tissues, particularly from the resistant rice genotype Nipponbare, was challenging. However, through optimization of the RNA extraction process and repeated sampling, we successfully got high-quality RNA.
3. What research project are you most excited about right now?
I’m particularly excited about leveraging the synergistic potential of epigenomics, spatial transcriptomics, and single-cell transcriptomics to deepen our understanding of plant-pathogen interactions and uncover distinct cellular immune states.
4. What drew you to your current lab?
Steven’s lab is at the forefront of host-pathogen interactions and plant transformation research, perfectly aligning with my interests. Its cutting-edge work in these fields provides a dynamic environment for scientific research. Additionally, having a PI who fosters professional growth was a significant factor in my decision.
5. How did you choose to join your current graduate program?
During my undergraduate studies, I had the opportunity to intern at the National Plant Health Laboratory, which sparked my fascination with plant-pathogen interactions and their critical role in agriculture and food security. This experience also ignited my interest in applying molecular techniques to better understand these interactions, ultimately shaping my choice of graduate program. I’m pleased to say that this field continues to captivate me to this day.
6. What advice would you give to starting graduate students?
Simply put, challenges are an inevitable part of research, from failed experiments to unexpected obstacles. The key is not to shy away from adjusting your strategy. Resilience and adaptability are invaluable traits in overcoming these hurdles. Embrace these challenges as learning opportunities and don’t hesitate to seek support when needed. Beyond data generation, graduate school is a transformative journey that sharpens problem-solving skills. Most importantly, stay curious!
7. Who has inspired you scientifically? Why?
In my field of research, Gebisa Ejeta stands out as an inspiring figure. His groundbreaking work on Striga has significantly improved the livelihoods of millions of farmers in Sub-Saharan Africa (SSA). His career exemplifies how a scientist can create meaningful impact, particularly through a steadfast commitment to advancing SSA agriculture—a path I aspire to follow.
8. Are/were you involved in other scientific/
professional development activities? How do/did these contribute to your training?
I’ve actively participated in science communication training and workshops to enhance my ability to share my research, along with other related studies, with both technical and nontechnical audiences, particularly my fellow youth. My goal has always been to highlight how my work can contribute to solving the societal challenges we face today. Additionally, I’ve been involved in a mentorship program offered by AuthorAid, which helped me cultivate my skills in scientific research writing and presentation. These experiences have been instrumental in shaping my ability to contribute to research with tangible societal impact, particularly in the area of food security.
9. What is the greatest challenge you have encountered in your career? What did you do to overcome this challenge?
Early in my career, my goal was perfection in all aspects of science. However, this pursuit often led to disappointment and made me question my abilities. Over time, I’ve realized that this focus on perfection was a significant setback. Now, I value progress in place of perfection. Consistent growth and learning have become essential tools for advancing in my field and continually improving.

11. Is there anything else you would like to share in your Spotlight? If so, what is it?
I appreciate the opportunity offered by IS-MPMI to be able to share my experience.
12. Bonus question: What’s your favorite pathogen or disease?
Although Striga is at the heart of my current research, I find maize lethal necrosis disease particularly intriguing. This interest most likely stems from it being the first disease I worked on when I began my research career during my internship.
13. Bonus question: What’s your favorite molecular plant pathology-related article?
That would be the review article on “The Plant Immune System” (Jones and Dangl, 2006). This article really laid a foundation for my comprehension of immune responses in plants.
