FGF signalling is required for krox20 enhancer B activity in the zebrafish embryo. (A-D) Transgenic embryos carrying the gfp gene under the control of the chicken Krox20 A enhancer [Tg(cA:gfp)] (A,B) or the zebrafish krox20 B enhancer [Tg(zB:gfp)] (C,D) were incubated in DMSO carrier (A,C) or SU5402 (B,D) from the 1-somite stage, collected at the 8-somite stage and subjected to double in situ hybridisation for gfp (blue) and krox20 (orange); overlap is purple (A-C). Embryos were flat-mounted with anterior to the left.
