Immunohistochemistry of grafted hypocotyl sections – extensins (JIM11, JIM12, and JIM20 epitopes) and AGPs (JIM13, JIM8, and LM2 epitopes). a – abundant occurrence of the epitope in the intercellular spaces (arrowheads), graft union area (arrows), and cytoplasmic compartments of cells adjacent to the graft union area (arrows), inset: epitope present in the cytoplasmic compartments (arrowheads) and on the cell surface (arrow). b – abundant occurrence of the epitope in the graft union area (arrowhead) and cytoplasmic compartments of the cells adjacent to the graft union area (arrows). c – epitope present in the intercellular spaces between the cortical cells (arrows). d – scion cells adjacent to the graft union area, epitope present in the cytoplasmic compartments (arrowheads) and on the cell surface (arrow). c Calcofluor White, ep epidermis. Scale bars: a and b = 50 μm; a inset, c, and d = 10 μm
