Hox3/zen and the evolution of extraembryonic epithelia in insects
Abstract
Insects have undergone dramatic evolutionary changes in extraembryonic development, which correlate with changes in the expression of the class-3 Hox gene zen. Here, we review the evolution of this gene in insects and point out how changes in zen expression may have affected extraembryonic development at the morphological and the genetic level.
