5.4kb EcoRI fragment of the ct regulatory region is fused upstream of a minimal Hsp70 promoter followed by lacZ reporter sequence.
A 5.4kb EcoRI fragment of the ctregulatory region fused to a minimal Hsp70 promoter drives EcollacZexpression in the inner cells of the posterior spiracles, theantenno-maxillary organs, the hypophysis, and the Malpighian tubules.
