Fig. 5. Pnt activates IroRE2-lacZ and ara/caup expression. (A,A') Overexpression of pnt in clones of cells (green) activates lacZ (red, arrowheads). (B,B') In pnt{Delta}88 null clones (absence of green) IroRE2-lacZ is downregulated (red, arrowhead). (C,C') ara/caup expression (red) is similarly lost in pnt{Delta}88clones (arrowhead).
