Team: Gene networks, development and evolution

Various mutational processes create and remove genes. The size of a gene family can be conserved or highly dynamic.
We are interested in the fate of some gene families according to:

  • cooption into new functions,
  • loss of functions,
  • adaptive processes in which they are involved.

Two major axes of research are explored within this framework:

  • Molecular and functional evolution of transcription factors involved in the development of vertebrates,
  • Molecular adaptation of digestive enzymes in metazoans.

Molecular evolution, gene families, adaptation, development, Evo-Devo, transcription factors, amylase, drosophila, insects, vertebrates, metazoans, Scyliorhinus canicula, Danio rerio, Oryzias latipes, Neoceratodus forsteri, Astyanax mexicanus.
