title: Insect serosa: a head line in comparative developmental genetics.
abstract: A recent study reveals specific functions of Hox3/zerknüllt (zen) in the extraembryonic and embryonic primordia of the red flour beetle, Tribolium castaneum. The results shed light on the functional evolution of bicoid, a zen paralogue of higher flies, which determines anterior body parts.
