Figure 7


Fig. 7. At-dpp RNAi embryos fail to break the radial symmetry. (A-C) DNA staining of untreated (A) and At-dpp RNAi (B,C) embryos at stage 8. All these embryos were also stained for At-otd transcripts. (D-R) Expression of At-en (D-F), At-otd (G-I), At-caudal (J-L), At-sog (M-O), and At-twi (P-R) transcripts in untreated (D,G,J,M,P) and At-dpp RNAi (E,F,H,I,K,L,N,O,Q,R) embryos at stage 9 (D-F,M-R) or stage 8 (G-L). D,G,J and P are lateral views and M is a ventral view; F,I,L,O,R are viewed from the directions indicated by arrows in E,H,K,N,Q. (S,S1,S2) Expression of At-pros transcripts in untreated (left in S) and At-dpp RNAi (right in S) late stage 9 embryos. The two boxed regions in S are magnified in S1 and S2. a, anterior; p, posterior; dpp Ri, At-dpp RNAi. Scale bars: 100 µm.
