A set of third chromosome mutant stocks derived by insertional mutagenesis using the P-element construct P{lacW}; most lines have a lethal or semi-lethal 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).
Insertion reported at 61bp upstream of the aay AUG codon.
Genomic location reported as 3L:9416589..9416589 .
The orientation of the insertion was not reported.
