Title
3,4-Dehydroproline Inhibits Cell Wall Assembly and Cell Division in Tobacco Protoplasts

Other claims from this paper (8)
- Intervention effect Dhp-treated tobacco protoplasts did not develop osmotic stability.
- Intervention effect Dhp-treated tobacco protoplasts did not initiate mitosis.
- Observation Untreated protoplasts assembled a dense fibrillar cell wall of laterally associating subelementary fibrils.
- Intervention effect Dhp-treated protoplasts formed microfibrils coated with globular knobs.
- Intervention effect Dhp-treated protoplasts formed larger fiber bundles with an open ribbon-like appearance.
- Intervention effect The smallest subelementary fibrils were not visible after Dhp treatment.
- Mechanism Tobacco cells developed abnormal morphology as a consequence of abnormal wall structure.
- Mechanism The authors infer that hydroxyproline-rich glycoproteins support primary wall integrity and correct assembly of other wall polymers.
