Les insectes présentent une étonnante diversité morphologique dans les organes de vol, et cette évolution a conduit à leur rayonnement au sein du règne animal. L'une des modifications les plus frappantes est la transformation des ailes postérieures en structures d'équilibrage très réduites, appelées haltères. Des travaux pionniers chez la drosophile ont montré que la spécification des haltères est sous le contrôle du gène Hox Ultrabithorax (Ubx). En revanche, la formation des ailes antérieures est décrite pour être indépendante des gènes Hox, mais cette observation est controversée chez d’autres insectes. Au cours de mon doctorat, j'ai réexaminé le rôle des gènes Hox pour la spécification des organes du vol chez la drosophile. Mes travaux m...
