Labeling of cells with LM25 (galactoxyloglucans) in the quadrifids (green color—a signal of antibody). The section positions are shown with circles and polygons on a schematic representation of quadrifids. (A) Section through quadrifid, arm (A), pedestal cell (Pc), basal cell (Bc), bar 10 µm. (B) Section through arm of terminal cell (A), positive signal in cell wall ingrowths in arms (arrow), bar 10 µm (C) Section through quadrifid labeled, arm (A), pedestal cell (Pc), basal cell (Bc), positive signal in cell wall ingrowths in arms (arrow), note positive signal in cell wall ingrowths in pedestal cell (star), bar 10 µm. (D) Diagram showing the occurrence of galactoxyloglucans (detected by LM25) in quadrifid cells: arm of terminal cell (A), pedestal cell (Pc), basal cell (Bc).
