| Title | Differential Physiological Responses to Salt Stress between Salt-Sensitive and Salt-Tolerant <i>japonica</i> Rice Cultivars at the Post-Germination and Seedling Stages. | |
|
Abstract: Soil salinity is a key source of abiotic stress in the cultivation of rice. In this study, two currently cultivated <i>japonica</i> rice species-Zhegeng 78 (salt-tolerant) and Zhegeng 99 (salt-sensitive)-with similar backgrounds were identified and used to investigate their differential responses to salt stress at the post-germination and seedling stages. Quantitative RT-PCR analysis demonstrated that the expression of <i>OsSOS1</i>, <i>OsHAK1</i>, and <i>OsHAK5</i> at the post-germination stage, and the expression of <i>OsHKT1,1</i>, <i>OsHTK2,1</i>, and <i>OsHAK1</i> at the seedling stage, were significantly higher in the salt-tolerant Zhegeng 78 compared with those of the salt-sensitive Zhegeng 99 under salt stress. The significantly lower Na+ net uptake rate at the post-germination and higher K+ net uptake rates at the post-germination and seedling stages were observed in the salt-tolerant Zhegeng 78 compared with those of the salt-sensitive Zhegeng 99 under salt stress. Significantly higher activity of peroxidase (POD) and the lower hydrogen peroxide (H2O2) accumulation were observed in the salt-tolerant Zhegeng 78 compared with those of salt-sensitive Zhegeng 99 under salt stress at the seeding stage. The salt-tolerant Zhegeng 78 might be valuable in future cultivation in salinity soils. |
