Other claims from this paper (14)
- Observation Tomato LeMDAR was isolated.
- Observation LeMDAR-GFP localized to chloroplasts in Arabidopsis mesophyll protoplasts.
- Intervention effect Sense LeMDAR tomato lines had increased reduced ascorbate versus wild type.
- Intervention effect Antisense LeMDAR tomato lines had decreased MDAR activity versus wild type.
- Intervention effect Antisense LeMDAR tomato lines had decreased reduced ascorbate versus wild type.
- Intervention effect Sense lines had less hydrogen peroxide under low and high temperature stress than wild type.
- Intervention effect Sense lines had less TBARS under temperature stress than wild type.
- Intervention effect Sense lines had higher net photosynthetic rate and PSII efficiency under temperature stress than wild type.
- Intervention effect Sense lines had higher fresh weight under temperature stress than wild type.
- Intervention effect Oxidizable P700 fell more in wild type and antisense than sense plants during chilling under low irradiance.
- Intervention effect Sense lines had significantly lower hydrogen peroxide under methyl viologen stress.
- Intervention effect Sense lines had higher APX activity under methyl viologen stress.
- Intervention effect Sense lines had greater photosynthetic rate and PSII efficiency under methyl viologen stress.
- Mechanism Authors infer chloroplastic MDAR overexpression alleviates PSI and PSII photoinhibition and boosts abiotic stress tolerance via AsA.
