Fig. 7. A mature cortical cell-specific marker is ectopically expressed in the epidermis of erh3 mutants. Expression of the J0671::GFP enhancer trap in wild type (A,C) and erh3-2 mutants (B,D). (A,B) Longitudinal sections. (C,D) Transverse sections. Images of GFP expression were superimposed over images of PI stained cell walls. Scale bar 50 µm.
