Fig. 4. NvFGF signalling regulates patterning within the aboral region. (A-P) In situ hybridisation of 48 hpf planulae. Lateral views, aboral pole to the left; probes are indicated above the panels, injected morpholinos to the left. Knockdown of NvFGFa1 and NvFGFRa causes specific loss of the apical organ marker, knockdown of NvFGFa2 results in expansion of the apical tuft. Displayed expression patterns were obtained in: (A) 38/42, (B) 31/38, (C) 21/23, (D) 36/36, (E) 48/53, (F) 58/65, (G) 14/18, (H) 29/31, (I) 39/42, (J) 24/33, (K) 22/24, (L) 46/52, (M) 29/34, (N) 27/29, (O) 26/36 and (P) 40/42 embryos.
