Wall Thickness of Vessels and Fibers in the Stems of Wild-Type, MYB46 Repressors, and MYB46 Overexpressors

Plant	Interfascicular Fibers	Vessels	Xylary Fibers
Wild type	2.27 ± 0.27	0.92 ± 0.15	0.59 ± 0.08
MYB46 repressors	0.58 ± 0.08	0.62 ± 0.10	0.14 ± 0.04
MYB46 overexpressors	1.72 ± 0.23	1.56 ± 0.31	0.60 ± 0.07

Wall thickness was measured from transmission electron micrographs of fibers and vessels. Data are means (μm) ± se from 15 cells.
