Abstract Drosophila melanogaster cells and tissues respond to heat shock by dramatically altering their pattern of transcription and translation, leading to the rapid synthesis of a small number of polypeptides, the heat shock proteins (hsps). By using cloned hsp DNA we have detected sequences complementary to heat shock genes in RNA prepared from non-heat-shocked animals of different developmental stages. Hsp 83 mRNA is present at high levels in all stages examined. Hsp 68 and 70 mRNAs are present at very low levels in most stages and at slightly higher concentration in pupae. Hsp 26 and 27 mRNAs are detected in embryos. Hsp 23, 26 and 27 mRNA are barely detectable in early third instar larvae but are major components of late third instar and early pupal RNA. Hsp 22 mRNA is also detected in early pupae. Later in development the levels of the small hsp mRNAs decrease but a further peak in abundance of hsp 26 and 27 mRNAs is found in mature adult females.
