Other claims from this paper (17)
- Intervention effect Sodium nitroprusside significantly alleviated UV-B growth suppression.
- Intervention effect NO donor allowed more green leaf tissue to survive under UV-B stress.
- Intervention effect NO donor prevented chlorophyll content reduction under UV-B.
- Intervention effect NO donor increased photosystem II quantum yield relative to untreated UV-B controls.
- Mechanism NO was interpreted as protecting maize chloroplast membranes.
- Intervention effect UV-B significantly accumulated flavonoids and anthocyanin in maize leaves.
- Intervention effect NO treatment intensified the increase of flavonoids and anthocyanin.
- Intervention effect UV-B caused lipid peroxidation in maize leaves.
- Intervention effect UV-B induced hydrogen peroxide accumulation in maize leaves.
- Intervention effect NO donor prevented UV-B increases in MDA and H2O2 contents.
- Mechanism NO was interpreted as an antioxidant scavenging H2O2 to protect cells.
- Intervention effect NO donor increased catalase and ascorbate peroxidase activities under UV-B relative to UV-B alone.
- Intervention effect PTIO arrested NO protection of leaf growth, photosynthetic pigment and radical scavenging.
- Intervention effect PTIO had little effect under UV-B compared with UV-B alone.
- Intervention effect LNNA significantly increased H2O2 and MDA accumulation under UV-B.
- Intervention effect LNNA decreased antioxidant enzyme activities under UV-B.
- Mechanism NO may signal activation of oxygen scavenging to confer UV-B tolerance.
