ABSTRACT
BACKGROUND:
The evolutionarily conserved odd-skipped related genes odd-skipped (odd), drumstick (drm), sister of odd and bowel (sob), and brother-of-odd-with-entrails-limited (bwl) act downstream of the Notch pathway in various insect tissues including the appendages and the gut. While the function of some of these genes have been analyzed in the adult Tribolium beetle, the expression during and their requirement for embryonic development is not known.RESULTS:
We describe here the embryonic expression patterns of drm, sob, and bwl and analyze the RNAi knockdown phenotypes with emphasize on the appendages and the hindgut. We show that in Tribolium, drm acts independently of other odd-family members in the formation of legs, hindgut, and the dorsal epidermis. Moreover, we establish drm and sob as further markers for segment borders in the appendages that include the gnathobasic mandibles.CONCLUSIONS:
We conclude that the regulatory interrelationship among the odd genes differs between Tribolium and Drosophila, where odd and drm seem to act redundantly. In Tribolium, the genes drm and sob uncover the relict of a precoxal joint incorporated in the lateral body wall.Palavras-chave
