Molecular analysis of the bicoid gene from Drosophila pseudoobscura: identification of conserved domains within coding and noncoding regions of the bicoid mRNA.

Abstract excerpt

The specification of anterior positional information during Drosophila embryogenesis is largely dependent upon the function of the maternal-effect gene bicoid (bcd). Two aspects of bcd function are particularly striking. First, the bcd protein product forms a gradient during early embryogenesis, which regulates the transcription of at least one zygotic segmentation gene, hunchback, in a concentration dependent...
