3D xylem architecture. A 3D render of each ROI (TW, OW or NW) from X-ray CT scans of RW induced trees (tipped T1, T2 and T3) or controls (C1, C2 and C3). The 3D ROI render on the right after the common vessel specific transfer function was applied in silico. B Total volume of vessels as a percentage of each ROI was averaged for each tissue. C Vessel surface area:volume ratio of each ROI was averaged for each tissue. Error bars = standard error of tissue type across 3 trees. * p < 0.05 (one-way ANOVA).
