[edit] Description
Microtubule dynamics during preprophase and prophase in plant cell mitosis.
The images follow a tobacco BY-2 cell through the first stages of mitosis. N = Nucleus, V = Vacuole, PPB = Preprophase band, MTN = Microtubule nucleation, NEB = Nuclear envelope breakdown. The growing ends of microtubules are shown in green (labeled with green fluorescent protein fused to the microtubule plus end binding protein EB1 of Arabidopsis thaliana).
- 1) and 2): The preprophase band is visible at the cell wall.
- 3) Microtubles start nucleating at the nuclear envelope.
- 4) The preprophase band starts to disappear.
- 5) Microtubules around the nucleus form the prophase spindle.
- 6) The nuclear envelope breaks down and the spindle microtubules occupy the nuclear space.
