Insertion lines from this collection were assessed for inclusion in the Gene Disruption Project collection.
A set of mutant stocks derived by insertional mutagenesis using the P-element construct P{PZ}; most lines have a lethal or sterile phenotype. The P{PZ} construct carries a ry[+] visible marker, Ecol\lacZ enhancer trap sequences, and bacterial sequences that allow plasmid rescue.
P{PZ}wb09437 maps to the fourth intron of wb. The insertion maps roughly 12500 bases from the 5' end of the intron based on sequence information but the exact insertion location is unknown.
