Description

A fragment containing 107bp of the janB gene and 348bp of 5' upstream sequences (inserted in place of the Sry-δ upstream and coding sequences present in the progenitor) is fused to the lacZ coding region.

Additional Information
Statement
Reference

Reporter transcript is detected in male late instar larvae and in adult males. Like endogenous janB transcript, the reporter transcript is expressed specifically in the gonad, and not in somatic tissues. For expression of the fusion protein, please see janBJBβSX.T:EcollacZPA.
