About the Cover
When associated with endogenous genes, green fluorescent protein (GFP) is a very useful reporter of gene expression and protein localization. A photo mosaic of a stage 10 Drosophila egg chamber that is made up of GFP images from the FlyTrap database is shown. See QUIN˜ONES-COELLO et al. (pp. 1089–1104) and BUSZCZAK et al. (pp. 1505-1531).
