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).

Location 2R:13955978-13955979 confirmed by FlyBase alignment of dbGSS accession AQ026143 to D. melanogaster arm Release_4 and heterochromatin Release_3.2b.

(FlyBase, 2005)

May be multiple insertion line: in situ data (56F11--56F12) conflict with location inferred from flanking sequence (55C9).
