Hox en Provence

In the nearly 25 years since the cloning of the first Hox genes, the broad brushstrokes of their functions in axial patterning have become familiar motifs in developmental biology. The October 2007 Fondation des Treilles workshop on “Hox Genes in Development and Evolution” in Les Treilles, France, highlighted some of the finer details regarding the function of these genes in shaping animal morphology.
