Pavement Cell Lobe Structure in Wild-Type and napp/pirp Mutants.

(A), (B), and (C) Leaf pavement cell shapes of wild-type (A), napp-1 (B), and pirp-2 (C) plants. The fourth rosette leaf of 2-week-old plants was cleared, and the adaxial pavements cells were observed using phase-contrast light microscopy. Bar = 50 μm.

(D) Comparison of lobe extensions in wild-type and mutant leaf pavement cells. The area and the perimeter were measured on 118 pavement cells in wild-type and mutant plants, and the ratio between area and perimeter was calculated for each cell.

(E) Comparison of cell area of wild-type and mutant pavement cells.
