Insertion in an intron.
Homozygous males copulate significantly less frequently than their heterozygous siblings and than wild-type controls. Those males that do copulate take significantly longer to begin copulation than control males. Homozygous males spend a similar fraction of time engaged in courtship behaviour as control males. Some matings do result in sperm being successfully transferred to the female. 72 hours after mating, sperm are rarely detected in the reproductive system of females mated to homozygous males, suggesting that the sperm have either been eliminated or degraded.
Pde1cc04487 is partially rescued by Pde1cRC.UAS/Scer\GAL4Pde1c.RC
Pde1cc04487 is partially rescued by Scer\GAL4elav.PU/Pde1cRC.UAS
Pde1cc04487 males which are expressing Pde1cRC.Scer\UAS under the control of Scer\GAL4Pde1c.RC are partially fertile, with more than 50% of male-female pairs producing progeny. The number of progeny resulting from successful matings is similar to control matings.
Pde1cc04487 males which are expressing Pde1cRC.Scer\UAS under the control of Scer\GAL4elav.PU are partially fertile, with less than 25% of male-female pairs producing progeny.
The copulation defects seen in Pde1cc04487 males are completely rescued by expression of Pde1cRC.Scer\UAS under the control of either Scer\GAL4Pde1c.RC or Scer\GAL4elav.PU.
Excision of the insertion can revert the male sterile phenotype.
