Genetic mapping of the coding regions for three heat-shock proteins in Drosophila melanogaster

We describe variants of three heat-shock proteins of Drosophila melanogaster and their use to map the chromosome regions that contain the coding sequences for these proteins. All three map to a region on chromosome 3L that includes only one heat-shock puff, designated as 67B. The results imply that the genes coding for at least three heat-shock proteins are included within the 67B region.
