| 1.11.1.11 | metabolism | Simulated acid rain (SAR)stress (pH 3.5/2.5) destroys the redox state in rice cells and induces H2O2 excessive accumulation, and inhibits growth of rice. Exogenous Ca2+ alleviates SAR-induced inhibition on activities of APX and GR by regulating the concentration, activation, and transcription of their isozymes, and then maintains the redox level of cells and protects cells from oxidative damage, being beneficial to the growth of rice, effect of Ca2+ on contents of AsA and DHA in leaves and roots of rice under the simulated acid rain stress, overview | Oryza sativa Japonica Group |
| 1.11.1.11 | physiological function | exogenous calcium enhances rice tolerance to acid rain stress by regulating isozymes composition and transcriptional expression of ascorbate peroxidase and glutathione reductase | Oryza sativa Japonica Group |
