Abstract

The organization and number of 70,000-dalton heat-shock protein genes of Drosophila melanogaster has been investigated in a wild-type Oregon R fly stock and in a KC cell line. Six copies were found in the KC cells, and slightly more were found in the Oregon R population examined. In both cases, the basic gene element consisting of the mRNA coding region plus a short 5' "noncoding" sequence element was conserved. Two gene variants distinguished by specific restriction sites were found in both genomic DNAs. Restriction maps of the six genes in KC cells showed that these two gene variants are arranged differently. Restriction analysis of Oregon R embryonic DNA revealed polymorphism in the organization of the genes, which is not observed in KC cells. The data suggest that the arrangement as well as the number of genes for the 70,000-dalton heat-shock protein in D. melanogaster is subject to variations at both the 87A and 87C cytogenetic loci.
