Other claims from this paper (4)
- Observation Preprophase bands were placed away from stomata and two precursor cell types.
- Mechanism Three cell types may signal to orient the division site.
- 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.
