Abstract: Body building The fruit fly Drosophila is the favoured model for the study of patterning in insect embryos. Yet its embryo patterning is actually not typical of most insects. Its body plan is established early on by a gradient of Bicoid protein, a morphogen that is present only in Diptera. Lynch et al. have examined embryo patterning in the parasitic wasp Nasonia vitripennis, which shares some elements with the fly in the way in which its body segments form, but does not contain the bicoid gene. In the wasp embryo the body plan is established via a gradient of orthodenticle, an ancient gene known to form a gradient in the early embryo of beetles. This is a striking example of developmental evolutionary change, and as a number of other insects used as lab organisms lack bicoid, it will be interesting to see if Nasonia's solution to body patterning is a general one.
