Description

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

(Bellen et al., 2011)

A set of mutant stocks derived by insertional mutagenesis using the P-element construct P{lacW}; most lines have a 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).

Comments
Comments

Deficiency complementation analysis indicates that the lethality of the chromosome is separable from the P{lacW}Tsp26ASH1372 insertion.

(Kahsai et al., 2016)

Location 2L:6000200-6000272 confirmed by FlyBase alignment of dbGSS accession AB082471 to D. melanogaster arm Release_4 and heterochromatin Release_3.2b. Insertion orientation confirmed.
