The PFE-Gal4 enhancer trap drives expression of UAS-nls-GFP in the eye-antennal disc proneural cluster cells UAS-nls-GFP expression pattern was observed in PFE-Gal4 heterozygotes (rdo+). GFP expression is evident in third instar larval eye-antennal imaginal disc proneural cluster cells including the ocellar, eye and antennal primordia. Photoshop was used to reduce the background over the entire image. The color range was selected to include only the intensely green areas and applied as a duplicated masking layer over the original image layer. The original image layer was then converted to black and white with a gradient map (black to white).
