Other claims from this paper (4)
- Observation Preprophase bands were placed away from stomata and two precursor cell types.
- Observation Asymmetric divisions were preceded by polarized cytoplasm with the band and vacuole at opposite ends.
- Observation Preprophase bands before symmetric guard mother cell divisions were broader than in asymmetric divisions.
- Observation Guard mother cell division sites had unusual end-wall thickenings.
