Fig. 6. AES abrogates SIX3- and SIX6-induced phenotypes. Dorsal views of stage 24 injected embryos hybridised with Rx2 probe. Embryos injected with 50 ng/µl of either SIX3 (A) or SIX6 (C) show ectopic Rx2 expression in the midbrain (open arrows). This phenotype is inhibited by co-injections of AES mRNA (B,D). Scale bar: 0.1 mm.
