The initiation of pair-rule stripes in the Drosophila blastoderm.
The interactions between the products of gap genes and pair-rule promoters results in the single most dramatic increase in the spatial complexity of gene expression during the segmentation process. We attempt to relate recent findings on the regulation of striped patterns of gene expression in the early Drosophila embryo to general strategies of gene expression and development employed by higher organisms.
