Expression of eyg during adult head development in Tribolium. (a-c) Lateral view of larval or pupal Tribolium head labeled by whole mount in situ hybridization for expression of eyg. Arrows indicate anterior border of the differentiating adult eye primordium. Anterior is right and dorsal is up. (a) Late resting larva stage. Expression of eyg is detected in a dorsoventral domain between eye primordium and the antenna. (b) Early pupa at about 12 h after pupation. Open arrowhead indicates posterior edge of the differentiating retina. (c) Pupal stage about 24 h after pupation. Arrowheads point at small eyg expressing cell clusters at the anterior retina margin and in the epidermis of the gena. Ant = antenna, gen = gena.
