@ISheizaf@ecoevo.socialGuillia Camply of @rmwaterhouse lab about #moulting genes in #arthropods. The most diverse group shares the trait of moulting. We can see it in the fossils record and every where around us but it is largely understudied. Trying to understand the history and the diversity of gene families and expression of this trait around all arthropods. Doing exceptional work of comparing between 150 proteomes and 65 gene families. How do change occur in arthropoda?

Ancestral state reconstruction analysis shows many diplications and deletions of ecdysone-related genes. Crustacean lineages seem to have lost e93 genes. Neverland family, the exdysteroid sybthesis pathway is very conserved in insects. However they couldn't find any gene from this family in coleoptera which opens a big question - how did this huge insect family replace this crucial genetic-biosynthetic pathway?
Assembling genomes of many arthropods, solving this and other questions
I am some what biased as Giullia and I work together on the evolution of moulting. I find this project and questions about one of the most universal trait in arthropod post-embryonic development to be of utmost importance and interest for the deep evolutionary mysteries.
Great first conference talk Giulia! #ProudPI
