Other claims from this paper (7)
- Intervention effect Elevated Zn2+ markedly reduced plant growth (by at least 50%) in non-acclimated tobacco plants.
- Intervention effect Acclimation increased tobacco plant dry mass and leaf area up to 1.6-fold compared with non-acclimated plants.
- Intervention effect In non-acclimated tobacco plants, 250 μM ZnSO4 caused transient membrane depolarization and stomatal closure within 24 h.
- Association Acclimation was associated with improved stomatal regulation in tobacco compared with non-acclimated plants.
- Association Acclimation was associated with a root membrane potential 37% more negative than in non-acclimated tobacco plants.
- Association Acclimation was associated with enhanced vacuolar Zn2+ sequestration compared with non-acclimated plants.
- Association Acclimation was associated with up to 2-fold higher expression of the tobacco MTP1 orthologue.
