Secretion of callose from protoplasts. CLSM images of ABF fluorescence in protoplasts at 0, 1, and 7 days of culture under the non-stress and stress conditions. Dashed lines indicate the cell shape. Arrows indicate micro-sized fibers secreted from protoplasts. Inset images indicate bright-field and CW fluorescence images of sections of protoplasts. All scale bars = 25 μm
