A short summary of Itumeleng`s research:          

My research represents a pioneering exploration into the intricate relationships between plants and their associated microbial communities, known as holobionts, within the context of agricultural sustainability amidst anthropogenic climate change. Through a series of empirical studies and theoretical frameworks, I have made significant strides in unravelling the complexities of plant-microbe interactions and their implications for crop resilience and productivity. Central to my research is recognising the pivotal role that microbial communities play in promoting plant health and resilience under changing environmental conditions. By investigating the dynamics of these communities, my work has shed light on the diverse array of microorganisms associated with plants and their functional roles in nutrient cycling, disease suppression, and stress tolerance mechanisms. Furthermore, my research underscores the importance of integrating holistic approaches to holobiont (plants and their associated microbiomes) management into agricultural practices. By harnessing the diversity of microbial communities associated with plants, I have proposed innovative microbial-based strategies for improving crop performance and reducing reliance on synthetic inputs, thus promoting sustainable agricultural systems.

My exploration of microbial biogeographical patterns in Mediterranean ecosystems has unveiled the complex interplay between soil microbes and environmental conditions. By unravelling the influence of evolutionary assembly processes and precipitation gradients on microbial communities, I've gained insights essential for tailoring agricultural management strategies to Mediterranean climates. Understanding these microbial dynamics is key to developing resilient cropping systems capable of withstanding the challenges posed by climate change. Similarly, my investigations into plant microbiome assembly and structure offer direct implications for agricultural productivity and resilience. By deciphering the colonisation patterns of the soybean microbiome, I've identified key microbial targets for enhancing plant health and productivity. These findings pave the way for innovative approaches to microbial-based crop management, offering potential solutions to mitigate the impacts of abiotic and biotic stresses on agricultural systems. Building upon my previous investigations into microbial biogeographical patterns in Mediterranean ecosystems, my current work extends our understanding of soil microbial dynamics in diverse agricultural landscapes. By leveraging cutting-edge techniques and interdisciplinary collaborations, my current lab is working on elucidating how microbial communities influence plant health and resilience in agroecosystems in Africa.

My current research programme at Stellenbosch University focuses on two main themes aimed at enhancing crop resilience in the face of climate change across Africa. The first theme is centred on understanding the role of plant-associated microbes in promoting plant growth and adaptation to environmental stressors. Here, I investigate how beneficial microbes can be vertically transmitted from parent plants to offspring or horizontally transferred between plants to promote rapid adaptation. By identifying the key mechanisms underlying these processes, we aim to develop innovative strategies for enhancing crop resilience. The second theme of our research program explores the potential of synthetic holobionts as a transformative approach to crop development. We aim to recreate holobionts with increased abiotic stress tolerance from isolated microbes and incorporate innate plant signalling peptides that modulate plant-microbe communication. This innovative approach involves engineering interaction between the plant microbiome and the host to confer stress tolerance traits. The goal of my lab is to revolutionise crop development technologies and empower farmers to cultivate resilient crops in Africa.

In the ever-changing environment of academia, what are some of the obstacles early career researchers are faced with?

Demanding and unreasonable teaching loads.

What would you regard as the most important aspects to consider to effectively support early career researchers?

Reduce the amount of time/classes Early Career Researchers (ECR) are demanded to teach. ECR need to develop their career and research programme. Unreasonable teaching loads for ECR hinders/diverts attention from 1) grant writing, 2) publishing, 3) student supervision, 4) research.

What excites you about your work? 

As a plant holobiont scientist, what excites me most about my work is the potential to uncover the intricate relationships between plants and their associated microbial communities. Understanding these interactions holds promise for developing innovative strategies to enhance crop resilience and productivity in the face of climate change. The prospect of contributing to sustainable agriculture by leveraging the holobiont concept to mitigate stress and disease in plants is profoundly motivating. Additionally, the interdisciplinary nature of this research, which integrates microbiology, ecology, and plant science, offers a dynamic and intellectually stimulating environment that continually drives my passion for discovery and innovation.

Moreover, I find great fulfillment in working with and giving back to the communities we serve. Outreach is a crucial aspect of my work, as it allows me to share knowledge and advancements with farmers, educators, and students, ultimately fostering a broader understanding and appreciation of plant science. Engaging with the community not only amplifies the impact of my research but also inspires the next generation of scientists and cultivates a collaborative spirit essential for addressing global agricultural challenges.

When you're not in the lab, library or in the field conducting research, what do you do to unwind?

When I am not in the lab, library, or field conducting research, I am often unable to find time to unwind due to my demanding teaching responsibilities. My unreasonable teaching load requires me to dedicate significant time to preparing for lectures, leaving little room for relaxation and personal activities. Despite these challenges, I strive to maintain a balance by engaging in outdoor activities such as hiking and gardening whenever possible, as well as reading literature outside my academic field to broaden my perspective.
