Starting #ESEB2025 a bit late, with an exciting symposium on whole genome duplication. They couldn’t fit all of the talks in, I’ll be talking on “Gene expression variability and evolutionary outcomes after whole-genome duplication in fishes” tomorrow in the Genetics symposium. #GeneDuplication #GenomeDuplication #MolecularEvolution

The #diatom genus Nitzschia lost photosynthesis to become free-living heterotrophs. This study shows how #HGT from marine bacteria, followed by #GeneDuplication & #neofunctionalization, allowed them to catabolize #alginate & live off brown algal polysaccharides @PLOSBiology https://plos.io/41WaW8e

Nice work on functional evolution of proteins after duplication by @Landrychristian lab https://www.science.org/doi/10.1126/science.ado5719 #duplication #GeneDuplication #MolecularEvolution

We posted this cool preprint between Xmas and new year, now time for a thread about the results: Begum et al "Phylogenetic modeling provides evidence for sudden shifts in expression after small-scale duplication in vertebrates and strong support for the ortholog conjecture"

Interesting preprint dating whole genome duplications in vertebrate evolution relative to hagfishes, which I had missed this Spring:
• 1 genome duplication before, 1 after hagfish divergence, +2 at the basis on cyclostomes
• nice investigation of relation between genome duplication and morphological diversification (not much).

Marjorie Liénard: method to express invertebrate opsin proteins in vitro, allowing to show spectral shifts in opsins in butterflies, with notably 2 paralogs of LW providing differentiation in function between the dorsal and ventral parts of the eye https://www.pnas.org/doi/abs/10.1073/pnas.2008986118 #SMBE2023 #opsin #GeneDuplication #paralog
