In the trunk of the Drosophila embryo, the segment polarity genes are initially activated by the pair-rule genes, and later maintain each other's expression through a complex network of cross-regulatory interactions. These interactions, which are critical to cell fate specification, are similar in each of the trunk segments. To determine whether segment polarity gene expression is established differently outside the trunk, we studied the regulation of the genes hedgehog (hh), wingless (wg), and… CONTINUE READING
