Molecular and functional evolution of gene families (MULTIGEN)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.
