title: Choriogenesis in the Lepidoptera: morphogenesis, protein synthesis, specific mRNA accumulation, and primary structure of a chorion cDNA from the gypsy moth.
abstract: Choriogenesis in silkmoths has been used as a model for relating developmental processes and evolutionary change. We now describe parallel studies in a nonsilkmoth lepidopteran species, the gypsy moth. Choriogenesis is described at the levels of ultrastructure, protein composition and synthesis, and specific mRNA accumulation. One complete chorion cDNA sequence is presented and features of its primary structure are discussed. This sequence is shown to be homologous to those of silkmoths.
