GENETIC CHARACTERIZATION OF THE 87C REGION OF THE THIRD CHROMOSOME OF DROSOPHILA MELANOGASTER

Ethyl methanesulphonate (EMS) was used to induce 39 lethal and 13 karmoisin mutations within Df(3R)kar3J, a nine-band deficiency extending from 87C1 to 87C9 (inclusive). Five complementation groups (four lethal and one visible) were identified and cytologically mapped between 87C4–5 and 87C9, one complementation group per band, with the exception of complementation group A, which is localized to 87C4–5. These positions were determined using a set of overlapping deficiencies, each having at least one breakpoint in the 87C1–9 region. Mutations within a single complementation group have similar lethal phases or subvital phenotypes, consistent with the notion that each complementation group represents a single functional locus. No mutations localized to 87C1–C3. The inability to induce mutations in the 87C1 heat-shock puff locus is consistent with the current interpretation of a duplication of coding sequences at the 87A7 and 87C1 heat-shock puffs.
