Movie 1.

Visualizing periclinal cell divisions. Leaves from plants expressing TAN-YFP were dissected, stained with propidium iodide (PI), and imaged via confocal microscopy. This movie is made from a sequence of Zslices from a representative scan. PI is visualized with the magenta channel and TANYFP is visualized with the green channel. Periclinally-oriented preprophase bands are visible as green rings running around the circumference of the cell as the focal plane passes through. Two periclinally dividing cells are indicated with arrows.
