Other claims from this paper (19)
- Intervention effect O. officinalis root-to-shoot biomass ratio was highest at 30 mg·kg− 1 Cd.
- Intervention effect O. rufipogon root-to-shoot biomass ratio was highest at 30 mg·kg− 1 Cd.
- Intervention effect root surface area decreased under 30 mg·kg− 1 Cd.
- Intervention effect root volume decreased under 30 mg·kg− 1 Cd.
- Intervention effect SRL (ratio of total root length to total biomass) was lowest under 30 mg·kg− 1 Cd.
- Intervention effect SRV (ratio of total root volume to total biomass) was lowest under 30 mg·kg− 1 Cd.
- Observation Wild rice exodermis cells were large and loosely arranged under 30 mg·kg− 1 Cd.
- Observation Some cortical thin-walled cells collapsed under 30 mg·kg− 1 Cd.
- Intervention effect casparian strips changed under Cd treatment.
- Intervention effect suberin layer changed under Cd treatment.
- Observation Electron-dense particle-like structures were observed in root cells under Cd treatment.
- Intervention effect O. officinalis thickness of the exodermis cells increased by 45.6% at 30 versus 0 mg·kg− 1 Cd.
- Intervention effect O. officinalis thickness of endodermis cell decreased by 30.4% at 30 versus 0 mg·kg− 1 Cd.
- Association O. officinalis root Cd content increased with Cd treatment concentration and exceeded shoot content.
- Association O. rufipogon root Cd content increased with Cd treatment concentration and exceeded shoot content.
- Association Soluble component proportion increased with Cd treatment concentration.
- Observation Cd fraction abundance ranked cell wall above soluble component above organelles.
- Observation O. rufipogon root-surface iron plaque Cd content rose initially and then fell.
- Mechanism The authors infer that Casparian strips and suberin tissue contribute to Cd deposition in wild rice roots.
