Dper\fru BAC clone (r1.3 scaffold 0:8550968..8730455 , clone address 36N18).
Dper\fru+t36N18 is a suppressor of lethal - all die before end of P-stage phenotype of fruAJ96u3/Df(3R)Exel6179
Dper\dsx+t31M5, Dper\fru+t36N18, dsxΔ/dsx1, fruP1.LexA/fruAJ96u3 has abnormal song phenotype
The semi-sterility of fruAJ96u3/Df(3R)Exel6179 mutants is rescued by combination with Dper\fru+t36N18.
The pupal lethality of fruAJ96u3/Df(3R)Exel6179 mutants is rescued by combination with Dper\fru+t36N18, the emerging transgenic rescue males are fertile and sing courtship song like Drosophila melanogaster with alternating bouts of pulse and sine song (no species-specific song interconversion).
dsx1 fruP1.LexA/dsxΔ fruAJ96u3 double mutants rescued with Dana\dsx+t21E22 and Dana\fru+t20H8 also sing like melanogaster with both pulse and sine song elements present, whereas mutants rescued with Dper\dsx+t31M5 and Dper\fru+t36N18 only sing normal-pulse song but not the sine song (but still do not display any evidence of species-specific song interconversion).
