Cell-specific promoters allow only spatial control of transgene expression in Caenorhabditis elegans. We describe a method, using cell-specific rescue of heat-shock factor-1 (hsf-1) mutants, that allows spatial and temporal regulation of transgene expression. We demonstrate the utility of this method for timed reporter gene expression and for temporal studies of gene function.
