Other claims from this paper (12)
- Intervention effect Low CO2 induced salicylic acid in Arabidopsis.
- Intervention effect Low CO2 induced abscisic acid in Arabidopsis.
- Intervention effect Low CO2 dramatically increased SA.
- Observation SA induction was abolished in the SA induction-deficient2 mutant.
- Mechanism The SA mutant result indicates SA is primarily synthesized by isochorismate synthase under low CO2.
- Intervention effect ABA level increased under low CO2.
- Observation Low CO2 altered expression of genes involved in SA and ABA accumulation.
- Intervention effect Low CO2 increased expression of SA- and ABA-responsive genes.
- Observation The SA response of Pathogenesis-Related genes was compromised under low CO2.
- Observation Low CO2 altered programmed cell death-associated gene expression.
- Observation High SA accumulation further manifested the gene responses.
- Association SA increase appears associated with suppression of nonessential genes and altered cell-death genes.
