Other claims from this paper (12)
- Intervention effect Salt stress reduced biomass most in roots, then mature and young leaves.
- Observation Roots accumulated the most Na(+), followed by mature and young leaves.
- Intervention effect Young leaves had increased electrolyte leakage, malondialdehyde and hydrogen peroxide only at 150 mM NaCl.
- Association Total antioxidant capacity and polyphenol content rose with salinity in roots and mature leaves.
- Observation Total antioxidant capacity and polyphenol content did not change in young leaves.
- Intervention effect Under salinity stress, reduced ascorbate and glutathione content increased in roots.
- Observation Total tocopherol increased specifically in shoot tissues.
- Observation Redox ratios decreased significantly in roots.
- Intervention effect Catalase and dehydroascorbate reductase activities rose in all salt-treated organs.
- Observation SOD, APX, GST and GR activities rose specifically in roots.
- Mechanism The authors infer that Na(+) is retained and detoxified mainly in roots.
- Mechanism The authors propose a possible role for ROS in root-to-leaf signaling and leaf defenses under salt stress.
