Fig. 3. SHR::GFP does not move from the epidermis even when supernumerary layers
are present. Longitudinal confocal images (A-D) and transverse section (E) of
pGL2::YFPER (inset in A), pWER::YFPER
(inset in C), pGL2::SHR::GFP (A,B) and pWER::SHR::GFP (C-E)
transgenic roots. pWER::SHR::GFP induces a pattern perturbation
resulting in supernumerary layers (C,E), while pGL2::SHR::GFP does
not alter the pattern (A). SHR::GFP does not appear to move from the epidermis
in either pGL2::SHR::GFP (B) or in pWER::SHR::GFP (D)
transgenic roots. Arrow in the inset of C indicates ep/LRC initial. ep,
epidermis; co, cortex; en, endodermis; sn, supernumerary layers. Scale bars:
50 µm in A,C,E; 25 µm in B,D.
