Abstract
Gap genes encode transcription factors involved in the patterning of the head-tail axis of insect embryos. In this issue of Cell, Savard et al. (2006) identify a beetle gap gene, mille-pattes, that encodes an unusual polycistronic transcript predicted to produce four conserved peptides. These results have interesting implications for the control of embryonic patterning in insects.
