Fig. 5. Expression of LeWUS after ablation of the stem cells. (A)
Longitudinal section through a meristem after ablation of the upper four to
five cell layers. (B-D) Transverse sections showing LeWUS expression
at various times after ablation as in A. (B) Immediately after ablation. (C)
One day after ablation. (D) Three days after ablation. P1 indicates
the leaf primordium that was present at the beginning of the experiment;
I1 denotes a primordium that was formed after the ablation. Scale
bars: 100 µm.
