We examined the consequences of the deacetylase inhibitor trichostatin A (TSA) on the development of Drosophila melanogaster. When fed to flies, TSA caused lethality and delayed development at concentrations as low as 5 μM, had stronger effects on males than females, and acted synergistically with mutations in the gene encoding the RPD3 deacetylase to cause notched wings, but did not appear to affect a SINA signaling pathway that is normally repressed by the SIN3 corepressor. These findings suggest that deacetylated histones play an important role in normal developmental progression and establish parameters for genetic screens to dissect the role of deacetylases in this process.
