Figure 3. — Typical examples of the spatial structure of drought-induced cortical lacunae in grapevine fine roots. A, Transverse microCT image showing the area covered by cortical lacunae in fine roots, and corresponding volume renderings (A1, 2, 3, 4) showing the 3-D shape of cortical lacunae in A. Dashed line corresponds to the approximate position of transverse microCT image from A. B, Example of a free-hand cross-section of a fine root showing cortical lacunae and cell wall remnants, similar to observation using microCT imaging. E, Embolized vessels (dark gray color); W, water-filled vessels (light gray color); CL, cortical lacunae; CWR, cell wall remnant; EP, epidermis; EN, endodermis; XY, xylem. Bars = 50 μm (when not specified).
