C. elegans HOT regions are functional promoters. (A) The indicated HOT regions (orange) were cloned directly upstream of a histone∷GFP fusion gene and examined for the expression of GFP using transgenic reporter assays. (B) Ten of ten assayed regions drove GFP expression. The expression in representative larvae stage 4 worms is shown. Coordinates of cloned regions and further information on expression patterns are shown in Supplemental Table S1.
