FEMS Yeast Research Poster Prize: Jassim Al-Oboudi
We send our congratulations to Jassim Al-Oboudi, who won the best poster prize at ISSY36 in Vancouver. This award is sponsored by our journal FEMS Yeast Research. His poster was titled “Population Structure and Genome-scale Diversity of Wild North American Torulaspora delbrueckii“.
The International Specialised Symposium on Yeasts (ISSY36) took place on 12-15 July 2022 in Vancouver, Canada with the theme Yeast Sea to Sky – Yeast in the Genomics Era.
Read our interview with Jassim Al about his research below:
What is your current position, and what was your scientific journey to get there?
I am currently a PhD student in the Microbiology Doctoral Training Program (MDTP) at the University of Wisconsin-Madison in the laboratory of Chris Hittinger. Before coming to UW-Madison I worked as a research technician studying the infant gut microbiome in the laboratory of David A. Mills at the University of California, Davis where I received my B.S. in Biochemistry and Molecular Biology. As an undergraduate at UC Davis I worked in a plant genetics lab and then a human genetics lab.”
Could you describe the research your poster covered?
My poster covered population structure and genomic diversity in a ubiquitous yeast species, Torulaspora delbrueckii. This species has gained attention for industrial application and much of its research focus has been placed on human-associated strains. I became interested in the natural history of this species and used 260+ environmental North American isolates from our lab’s strain collection to ask questions about the ecology and evolution of this species. Before the really interesting stuff can be addressed, I needed to assess the presence of population structure in my strain set to differentiate genomic divergence due to population separation from that caused by natural selection. In doing so, I identified several large subpopulations with substantial genome-wide nucleotide divergence compared to each other. The populations are not separated by distance or by the substrate they were isolated from (e.g. soil, bark, leaves, etc;), meaning something yet unknown is driving divergence of these populations. Additionally, one of the more divergent populations exhibited statistical parameters that suggests it may have gone through a recent selective sweep or a bottleneck associated with a recent migration event.”
What do you hope to focus your research on in the future?
Broadly, I want to continue investigating basic questions in microbial ecology. After attempting to identify what is driving subpopulation divergence in my current dataset, I will move to answering questions about this species’ ecology and evolution. I plan to continue this trend into the future, leveraging my experience working with genome-scale datasets to improve our understanding of the behaviors, lifestyles, and potential applications of natural microbial populations.”

FEMS Microbes is excited to present its latest thematic issue, focusing on bacterial-viral co-infections. Host and microbial factors are critically important for influencing the severity and outcome of infection. Interactions between microbes is an understudied yet important aspect to this process.
