Hox gene cluster and expression patterns of Ma-bcd and Ma-zen in Megaselia. (A) The Hox-C of Drosophila and homologous genes in vertebrates (Hox1–13) (4–7). Dfd (Deformed), Scr (Sex combs reduced), ftz (fushi tarazu), Antp (Antennapedia), Ubx (Ultrabithorax), and abdA (abdominal A) form a subgroup of Antennapedia related genes. lab, labial; pb, proboscipedia; zen, zerknüllt; bcd, bicoid; AbdB, Abdominal B. (B to F) In situ hybridization showing the transcript distribution of Ma-bcd in the oocyte (B–D; arrows), nurse cells (D; asterisk), and embryos before (E) and during (F) cellularization. (G–J) Patterns of Ma-zen transcripts before (G), during (H), and after (I, J) gastrulation. In Drosophila, zerknüllt is expressed also in the pole cells (22).
