Immunohistochemistry of pectins in the grafted hypocotyls (whole mount). a – epitope present at the cut surface (arrows), weak fluorescence signal on the surface of the graft union cells, dotted lines – outline of the scion and stock. b and c – abundant occurrence of the epitope on the surface of the graft union cells (arrowheads), at the cut surface (arrows), and in some of the epidermal cells (full arrows), dotted lines – outline of the scion and stock. d–f – abundance of the epitope in the bead-like structures (arrowheads) and on the callus cell surface (arrows). c Calcofluor White. Scale bars: a–f = 50 μm
