Pair-Rule Gene Orthologues Have Unexpected Maternal Roles in the Honeybee (Apis mellifera)
Pair-rule genes are a set of genes identified in Drosophila melanogaster that act in segmentation [1]. The early maternal expression of Am-eve, Am-ftz and Am-run, and the severe effects on both anterior/posterior and dorso/ventral patterning, imply that these genes may have significant patterning roles early in development.
