Completely male lethal at 18oC in single copy at 18oC. This phenotype is mitigated by SxlfP7B0. In a SxlfP7B0 background, SxlFL.Hsp83 males are 15% as viable as their siblings without the transgene, suggesting that SxlFL.Hsp83 can transactivate the endogenous gene. In a SxlfP7B0 background males show intersexual characteristics. They have lighter abdominal pigmentation, rotated genitalia, fewer sex combs and are sterile.
SxlFL.Hsp83 has phenotype, suppressible by msl-2Hsp83.PK
SxlFL.Hsp83 is partially rescued by SxlfP7B0
SxlFL.Hsp83 partially rescues Sxlf2593
SxlFL.Hsp83 partially rescues Sxlf7,M1
SxlFL.Hsp83 partially rescues SxlM1,f3
Rescue of Sxlf7,M1 is more complete than that of SxlM1,f3. Rescue of Sxlf2593 by SxlFL.Hsp83 is more effective than that by SxlFLΔ.Hsp83 or SxlNΔ.Hsp83.
