Fig. 6. Cortical- and endodermal-specific marker is ectopically expressed in the epidermis of erh3 mutants. Expression of the J0571::GFP enhancer trap in wild-type (A,C) and erh3-2 mutant (B,D) meristems. (A,B) Medial longitudinal sections. (C,D) Transverse sections. Red arrowheads indicate ectopic expression in epidermal cells. Images of GFP expression were superimposed over images of PI stained cell walls. Scale bar, 50 µm.
