Detailed Description
Statement
Reference

Homozygous pont5.1 larvae hatch at normal rates, showing that the zygotic product is not essential for embryogenesis. The mutant larvae live for up to 7 days but grow only minimally in size. Clones of pont5.1 cells located within phenotypically wild-type wing imaginal discs grow poorly, indicating that the observed defects are cell-autonomous. Only a few small pont5.1 clones survive at 72 hours after induction of the clones, with none observed after 120 hours, suggesting cell competition. In contrast, when the cells surrounding the pont5.1 clones are are growth impaired, the mutant clones thrive even at 120 hours after induction. pont5.1 cells are not smaller than wild-type control cells.

Mutant animals die at first instar larval stage.

Genetic Interactions
Statement
Reference

The low-penetrance "held-out" wing phenotype of brm2/+ adults is enhanced in a pont5.1/+ background. Held-out wings are observed in 15% of double-heterozygous animals compared to 1.4% in brm2/+ mutants. Co-expression of pontScer\UAS.cDa under the control of Scer\GAL4arm.PS in brm2/pont5.1 animals reduces the penetrance of the wing phenotype to 1.7%.

Triple-heterozygous brm2, pont5.1, and rept35 mutant adults have a "held-out" wing phenotype at a low penetrance (2.1%), quite similar to the penetrance observed in brm2/+ animals.

The defects of pont5.1 rept35 double mutants are similar to the single mutants, although the larvae do not survive for longer than 5 days after egg deposition.
