Figure 3.

Cell length (white symbols) and cross-sectional cell perimeter (black symbols) plotted against distance from the ligule for abaxial (a) and adaxial (b) cells of wild type (▵), M489 dwarf (□), and M489 + GA₃ (○) (± se, n = 9). Cell perimeters were measured throughout the EZ of 50%-elongated blades (n = 9, ± se) and mature perimeters were measured in fully grown leaves (n = 36, ± se). Arrows summarize the orientation of CMTs (r, random; t, transverse) at the corresponding positions throughout the EZ of the dwarf and tall plants.
