    Impact of Lateral Gene Transfer in eukaryotic evolution

    Résumé : 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. Finally, I will discuss our current research plans to better understand what favours or hampers the acquisition and maintenance of foreign genes in a genome.
