"Impact of Lateral Gene Transfer in eukaryotic evolution"

Abstract :
Lateral gene transfer (LGT) has been increasingly used to explain the presence of ‘unexpected’ genes in eukaryotes. Despite numerous independent studies on a variety of eukaryote lineages showing what appears to be clear examples of LGT, there is debate over the frequency and impact of laterally acquired genes within eukaryotes. While analyses thus far have suggested LGT occurs less frequently in eukaryotes than in prokaryotes, the apparent rarity compared to LGT in prokaryotes does not mean it should be disregarded as an important factor impacting eukaryotic evolution. Here I will review evidence for potential mechanisms of LGT in eukaryotes and discuss the impact LGT has had on the evolution of microbial eukaryotes in particular by acting as a catalyst for acquiring novel traits and laying the foundation to explore and thrive in various ecological niches.


About me :

My primary research interests are in evolutionary microbiology. I am particularly interested in the origin and evolution of eukaryotes. Among others, I’ve been investigating the horizontal exchange of genetic material that have occurred between distantly related eukaryote lineages. To tackle those questions, I have mainly used comparative (meta)genomic and molecular phylogenetic approaches, and I have focused on understudied unicellular eukaryotes (protists).
