摘要
Antheraea yamamai (Japanese oak silkworm) is a kind of silkworm of great economic value. and the process of the expression of its silkprotem genes is a perfect model for the study of molecular regulation during the development and differentiation. So studying its fibroin and allied genes is of both theoretic and practical magnitude A YAC library with an average size of 570kb is constructed from the posterior silk gland, using pYAC4 as a vector. The library was screened by means of polymerase chain reaction, and clones representing fibroin gene were isolated and characterized.
