esc promoter sequences (nucleotides 2L:11829236-11830492 of the release 3 genome sequence) drive expression of cDNA sequences encoding the escl open reading frame (incompletely spliced variant, contains intron 2 sequences) and 3'UTR. The escl open reading frame is tagged at the N-terminal end with Tag:FLAG.
esc6, esclinc.esc.Tag:FLAG has viable phenotype
esc6, esclinc.esc.Tag:FLAG has female fertile phenotype
esc6, esclinc.esc.Tag:FLAG has sex comb | ectopic phenotype
The presence of esclinc.esc.T:Zzzz\FLAG permits the recovery of adult progeny in a homozygous esc6 stock. The rescued homozygous females are fertile, while the rescued males have extra sex combs on their legs.
