..., we carried out a screen for genes that affect follicle cell fate specification or differentiation. We identified extra macrochaetae ( emc ), which encodes a helix-loop-helix protein, as a downstream effector of Notch signaling in the ovary. EMC is expressed in proliferating cells in the germarium...
