Salinity tolerance in rice cultivars is linked to a fourfold greater increase in glutathione and antioxidant capacity within 24 hours under sulfur-containing saline conditions.
- Why it matters: Understanding how different rice genotypes adjust sulfur metabolism during salinity stress is crucial for improving crop resilience and productivity in salt-affected soils.
- What they did: Researchers exposed four Oryza sativa ssp. japonica cultivars with contrasting salinity tolerance to a saline solution mimicking seawater ionic composition, analyzing physiological, biochemical, and transcriptional responses.
- The result: Tolerant cultivars showed reduced ROS accumulation, increased glutathione levels, and upregulated sulfur assimilation and biosynthetic genes, indicating genotype-dependent strategies for redox regulation and sulfur utilization during early salinity adaptation.
