Retains fewer than six IGS repeats.
Deletion derivative that retains a segment of the 5' intergenic spacer (IGS) but deletes the bb transcription unit, ry+t7.2 and the 3' P-element end.
construct_comment: One of a series of derivatives (3\'deletions) of P{rib7}, generated in vivo by exposing the insertion P{rib7}1A1-4 to transposase.
report comment: No selectable marker; ry+t7.2 also deleted.
