Figure 5. Null alleles of ocm results in decreased cell numbers in the fly eyes.

Different ocm alleles were assayed for cell viability in Drosophila eye. (A-B) ocm^S1590F, a weak hypomorphic allele of ocm does not affect cell growth. Other hypomorphic alleles, ocm^G1646E and ocm^V1286D were also tested but they are indistinguishable to ocm^S1590F (data not shown). Increasingly severe alleles (C–D) ocm^V1334D, (E–F) ocm^{166 Δ11 bp} (null allele) result in fly eyes dramatically reduced in size.
