Figure 2.

Ubiquitous expression of the Pcmt gene in Drosophila embryos. In situ hybridization of dechorionated stage-12 embryos was performed as described in Materials and Methods. Embryos are oriented with the anterior end of the embryo toward the top of the figure. The dorsal (A) and side (B) views of embryos hybridized with antisense probes are shown as well as the side view of an embryo hybridized with a sense probe (C). The positions of the embryonic brain (b), midgut (mg), ventral nerve cord (vnc), and amnioserosa (as) are indicated.
