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).

Additional Information
Statement
Reference

Enhancer trap expression is observed in the eye imaginal disc and is strongest posterior to the morphogenetic furrow. In embryos, expression is observed in muscle precursor cells and in developing muscles.
