Imprecise excision of P{lwB}AA142 resulting in a deletion that lacks the 5' exons of Fhos isoforms PI, PJ and PH as well as the first exon of all Fhos mRNA-encoding isoforms, and parts of the Prm gene.
Df(3L)knittrigΔ1 embryos transheterozygous with Df(3L)knittrigΔ140 show reduced formation of ganglionic tracheal branches with significant penetrance - the majority of embryos show disruption in at least one ganglionic branch. No abnormal phenotype is detected for midline glial cells.
Df(3L)knittrigΔ1 flies transheterozygous with Df(3L)knittrigΔ140 show reduced viability and only rare escaper flies are found. Most mutants die during pupal stages or as pharate adults. Most escapers are unable to undergo complete wing inflation, causing wrinkled wings. Some escapers show partially inflated and abnormally opaque wings. Mutant pupal wings appar normal.
