Expression of Blimp In all panels, anterior is to the left and ventral views. Panels A´–D´ represent SYBR Green staining of the embryos shown in panels A–D. Dashed lines mark the position of the posterior pit region. Arrowheads point to expression in the embryonic slit. The asterisk in panel D marks the mouth that does not express Blimp in later developmental stages. Developmental stages are indicated (staging system after [9], their supplementary data).
