Figure 5.

Detailed views from the localization of XEH activity in 6-d-old Arabidopsis roots using XXXG-Res. A, Col-0, the region corresponding to the top portion of Figure 4A (approximately 2 mm from the root tip). B, xth31-1/xth32-1 double knockout, the region corresponding to the top portion of Figure 4B (approximately 2 mm from the root tip). C, Col-0, emerging root hairs. D, xth31-1/xth32-1 double knockout, emerging root hairs. E, Col-0, root tip. F, xth31-1/xth32-1 double knockout, root tip. As in Figure 4, representative images from the analysis of approximately 10 plants from each line are shown. [See online article for color version of this figure.]
