Fig. 4. WUS expression rescues pol pll1 mutants. (A-D) Wild-type Ler (A), grafted pol pll1 (B,C) and wus-1 mutants (D) expressing PAP1:WUS (see text) all developed extensive meristem-like proliferations upon the transition to flowering (C and D shown at higher magnification). PCLV3:GUS activity in control (E) and PAP1:WUS (F) plants indicates a stem cell-like character for these proliferations, whereas PWUS:GUS activity is similar in control (G) and PAP1:WUS (H) plants. PER:WUS results in similar, but weaker, phenotypes in Ler (I) and pol pll1 grafted (J) plants.
