Additional Information
Statement
Reference

Faint staining is observed in narrow stripes in the dorsal epidermis of even parasegments 6-12. The pattern does not resemble the "ftz-like" stripe pattern of related Ubx.pbx constructs but rather a basal pattern observed in truncated Ubx promoter constructs.
