Cortical Microtubule Organization and Alignment in Cotyledon Epidermal Cells

(A) Pavement cell.

(B) Petiole cells.

The top panels show a representative confocal image of MTs in each cell type, while the bottom panels show the distribution of MT orientations based on examining more than 1,000 MTs from each cell type. Scale bar represents 20 μm. Asterisks above graphs give the level of statistical significance of the difference in MT angle distribution with the corresponding WT. For the double mutant, statistical significance was obtained comparing with both the Ler and Ws backgrounds. See also Figure S1.
