Other claims from this paper (12)
- Observation The dreb1a line is a null mutant in the DREB1A gene.
- Intervention effect Under cold stress, dreb1a seedlings did not differ phenotypically from the wild type.
- Intervention effect Under salinity, dreb1a plants had about 11% less seed germination than WT-Col0 plants.
- Intervention effect Under salinity, dreb1a plants had four times lower survival rate than WT-Col0 plants.
- Association Under normal conditions, DREB1A expression level correlated directly with root length.
- Association OX28 had 97% more reactive oxygen species accumulation than control seedlings.
- Association dreb1a had 31% less reactive oxygen species accumulation than control seedlings.
- Association dreb1a had significantly higher activities of superoxide dismutase, peroxidase and polyphenol oxidase than WT-Col0.
- Association dreb1a had significantly lower catalase activity than WT-Col0.
- Association dreb1a showed no difference in extracellular peroxidase activity compared with WT-Col0.
- Association OX28 had higher extracellular peroxidase activity.
- Mechanism A precise DREB1A expression level is required for proper growth and development in A. thaliana.
