Description

Insertion lines from this collection were assessed for inclusion in the Gene Disruption Project collection.

(Bellen et al., 2004)

A set of mutant stocks derived by insertional mutagenesis using the P-element construct P{lacW}; most lines have a lethal or sterile phenotype. The P{lacW} construct carries a w+mC mini-white visible marker, Ecol\lacZ enhancer trap sequences, and bacterial sequences that allow plasmid rescue (FBrf0049800).
