TEM and measurement of SCW thickening for control and T
transgenic plants. (A) Xylem cell wall of WT, (B) Xylem cell wall of T2 dwarf 35S:HvCesA4,
(C) Sclerenchyma cell wall of WT and (D) Sclerenchyma cell wall of T2 dwarf 35S:HvCesA4. Scale bar is 1 μM for (A, B) and 10 μM for (C, D). Cy = Cytoplasm of bundle sheath cell, ML = middle lamella. (E, F) Percent AIR extracted (w/w) from 35S:HvCesA4, 35S:HvCesA8 and control from stem tissues. (G) % reduction of xylem cell wall thickness as measured using ImageJ.
