abstract：:We present a genetic, developmental and molecular analysis of lethal(1)discs large-1[l(1)d.lg-1; Stewart et al., 1972], an oncogene of Drosophila. Mutations in this gene cause the imaginal discs to grow by cell proliferation beyond their normal final size, transform into solid tumors, fuse with one another and the bra...
