Figure Caption

Fig. 1 Loss of function of grhl2b leads to severe defects in the MHB region. (A,B) Embryos injected with control or grhl2b ATG-blocking MO. Lateral views with dorsal views in the insets. MB, midbrain; HB, hindbrain; apoptosis and folding defects are indicated by arrows and arrowheads. (C,D) Apoptosis is increased in grhl2b morphants (MO:grhl2b) compared with controls. (E-H) Positioning of either the midbrain (otx2) or hindbrain (gbx1) territories within the neural plate in grhl2b morphants compared with controls. (I-L) Expression of eng2a in grhl2b morphants and controls from the onset of MHB formation. (M-V) Expression of MHB patterning genes (eng2a, her5, wnt1 and pax2a) at 26 hpf in grhl2b morphants and controls. mhb, midbrain-hindbrain boundary; os, optic stalk; ov, otic vesicles.
