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{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).
Enhancer trap staining is observed in embryos in the foregut, posterior spiracles and anal pads. In ovaries, staining is observed in border cells and in columnar follicular epithelial cells. In third instar larvae, staining is observed in the gut, brain, and imaginal discs.
l(2)k09713
Reported to be inserted 838 bp downstream from the 5' end of intron 1.
This insertion was listed in the BDGP database as a lethal or sterile line during the period 1994-1999, but was not verified as such prior to the summary publication (FBrf0111489). Reasons for excluding lines from the collection described in FBrf0111489 include presence of more than one P insertion on the mutant chromosome, separation of lethality (or sterility) from the location of the insertion, and loss of lethality (or sterility) from the stock.
