Changes in Cell Wall Thickness in Line 25.

(A) and (B) Transmission electron micrographs of transversal sections of abaxial epidermal limb cells at anthesis of the wild type (A) and line 25 (B). c, cytoplasm; cw, cell wall; n, nucleus; v, vacuoles. Bars = 2 μm.

(C) Thickness of radial cell walls and tangential cell walls in the wild type and line 25. Error bars represent standard errors; n = 20 different cells from 20 different micrographs. Each value is the average of three measurements in one cell.
