Epifluorescence and Video Analysis of Vacuole Motility and Development in Stomatal Cells of Allium

Abstract
The vacuole in stomatal cells of Allium undergoes major changes in shape during differentiation, switching from a globular form in new guard mother cells to a network of interconnected tubules and chambers, and then back to a globular form as guard cells mature. In addition, vacuolar network elements exhibit characteristic movements and rearrangements.
