Divergent control of spatial and temporal expression by (A) Caenorhabditis elegans and (B) Pt-daf-7 promoters in C. elegans. DsRed under the control of the Ce-daf-7 promoter is restricted to the ASI neuron pair only and is visible only in L1s and L2s (L2 pictured). In contrast, GFP under the control of the Pt-daf-7 promoter is expressed in a large number of cells in the head, including amphidial neurons, predominantly in dauer larvae (pictured). This expression pattern from the Pt-daf-7 promoter correlates with its peak expression in Parastrongyloides trichosuri infective larvae (Crook et al., 2005). Adapted from Crook et al. (2010).
