Drosophila melanogaster is polymorphic for a specific repeated (CATA) sequence in the regulatory region of hsp23.

Gene - 20 Aug 1999

Frydenberg J, Pierpaoli M, Loeschcke V

Abstract excerpt

To identify sequence variation associated with a selection response for heat tolerance in Drosophila melanogaster, we sequenced 1400bp of the heat shock protein 23 gene (hsp23) promoter region in four heat-selected and two control lines. The region was found to be variable for a specific (CATA) repeated sequence, and the sequence CTT seems to be a hot spot for mutation. The repeated tetranucleotide sequence was...
