Fig. 7. dachshund expression in the labrum of wild-type and
TSp8RNAi embryos. (A) In the wild type, the dac
expression domain (arrow) is seen in a middle position of the labrum. (B) In
T-Sp8 RNAi embryos the distal part of the labrum is lost and the
dac domain (arrow) comes to lie at its anterior margin.
