Other claims from this paper (6)
- Intervention effect Silicate addition significantly increased seedling biomass of rice under 200 uM Zn contamination.
- Intervention effect Silicate addition decreased Zn concentration in roots and shoots of rice seedlings and in xylem sap flow.
- Observation Zn and Si co-localized in the cell wall of metabolically less active tissues, especially in root sclerenchyma.
- Intervention effect Silicate supply increased the cell wall bound fraction of Zn by about 10%.
- Mechanism Si-assisted Zn tolerance of rice is mainly due to reduced uptake and translocation of excess Zn.
- Mechanism Stronger binding of Zn in the cell wall of less bioactive tissues might also contribute to Zn tolerance to some degree.
