β¦ Synopsis
Heat shock of 37 degrees C applied to Drosophila embryos at blastoderm stage induces phenocopies of some dominant mutants of the bithorax complex. Heat shock might shut down functions of cis regulator genes involved in embryonic pattern formation.

The synthesis of heat shock proteins (hsp) has been examined during the early embryogenesis of Drosophila melanogaster. Normal protein synthesis stops after heat shock at all developmental stages, while hsp synthesis is induced only after treatment at blastoderm and later stages. The small hsps cont
The effect of inhibitors of protein synthesis on RNA synthesis was investigated before and during heat shock. The results indicate that proteins specifically made following heat shock might be required for the resumption, after heat shock, of the synthesis of the RNA normally made at 25 degrees C. I
