Light microscopy micrographs (A, B) and scanning electron micrographs (C, D) of control (A, C) and APG (B, D) strawberry fruit tissues. Tissue sections for light microscopy were stained with toluidine blue. Arrows indicate vascular bundles, and arrowheads indicate small, well-stained tri-cellular junctions. The large spaces without cells are indicated by asterisks. Scale bars correspond to 10 μm (A, B) or 200 μm (C, D). (This figure is available in colour at JXB online.)
