Cover: Genetic mosaics of Drosophila larval muscles using the PG157-Gal4 driver (transgene expressing muscles, green; F-actin, red; nuclei, blue). Nuclear ploidy and muscle growth are regulated autonomously by Insulin receptor (InR)/Tor signaling and dMyc activity, and in turn systemically affect body size and proportion. See Research article by Demontis and Perrimon on p. 983.
