(D, E) olvas expression in zen (D) and wild-type (E) embryos at stage 29 in lateral views. olvas expression is indicated by a white arrow. Insets show an overview of each embryo. (F,G) olvas expression in zen mutant (F) and wild-type (G) larvae (1 dph). Lateral view. (F',G') Magnificationof the gonadal region in (F) and (G). olvas expression is indicated by a white arrow. zen mutant larva has few olvas-positive cells. A small black arrow indicates a line of pigments. Scale bar, 100 um.
