Figure 6. RNAi knock-down of complementary gap genes (alternating cushions).
Columns show the expression of hb (A–C; yellow), kni (D–F; red), gt (G–I; blue), and Kr (J–L; green) in wild-type embryos (top row; A, D, G, J), in RNAi-treated embryos as indicated (middle row; B, E, H, K), and as summary graphs comparing wild-type boundary positions (grey) to boundary positions affected by RNAi (coloured lines) (bottom row; C, F, I, L). All embryos are at time class T4. Embryo images show lateral views: anterior is to the left, dorsal is up.
