title: Playing by pair-rules?
abstract: Although in Drosophila pair-rule genes play crucial roles in the genetic hierarchy that subdivides the embryo into segments, the extent to which pair-rule patterning is utilized by different arthropods and other segmented phyla is unknown. Recent data of Dearden et al.1 and Henry et al.,2 however, hint that a pair-rule mechanism might play a role in the segmentation process of basal arthropods and vertebrates.
