Fig. 1.
Vegetative phenotypes of wild-type, sle1-1, and sle1-2 plants. (A) Fourteen-d-old seedlings of wild-type, sle1-1, and sle1-2 plants. Sections of the third-leaf blades are shown in the inset. (B) Mechanically unrolled third-leaf blades of wild-type, sle1-1, and sle1-2 plants (left to right). Bars, 5cm (A), 3mm (B). (C–F) Comparison of width (C, D) and length (E, F) of leaf blades among wild-type, sle1-1, and sle1-2 plants. Results for the second and third leaves are shown, and for the flag leaf (FL) and leaves one and two lower than the flag leaf (FL-1 and FL-2, respectively). Results are shown as means ±standard error (SE) (n=10). (G) The abaxial surface of the third-leaf blade of wild-type and sle1-1 plants. The representative cells are outlined in black. Bars, 50 μm. (H, I) Comparison of epidermal cell size (H) and number of cells (I) in the third-leaf blade among wild-type, sle1-1, and sle1-2 plants. To estimate the number of cells comprising the third-leaf blade, the width and length of the leaf blade were divided by those of epidermal cells. Results are shown as means ±SE (n=5).
