Oral and poster presentation at the 2024 OIST-CNRS workshop in Okinawa

Abstract

Genome scrambling in the Tree of Life.

We recently reported that the zooplankton Oikopleura dioica comprises multiple cryptic species for which no morphological markers could be found, but that dramatically differ in gene order. We showed that process of “scrambling” their genomes is faster than in Ciona (another tunicate), Drosophila or Caenorhabditis (invertebrates which have in common with Oikopleura a small genome size and a short life cycle). Is Oikopleura doica's genome exceptional in comparison to all other living beings? I am testing this hypothesis with a pairwise genome comparison screen in clades distributed across the whole Tree of Life. In this poster, I will report my preliminary results with a focus on marine organisms.

Poster presentations on April 23–25 and flash talk on April 25.
