Additional Information
Statement
Reference

721 bp of upstream sequence drives expression in the wild-type salm transcript expression pattern in the blastoderm, in the anterior (parasegments 1-3), "horse shoe-shaped" (acron anlagen and the procephalic neurogenic region), and the "posterior" (parasegments 14, 15, and part of the hindgut primordium) domains.
