Sulfur deficiency combined with water deficit in pea triggers synergistic redox responses, upregulating 38 genes at both transcript and protein levels, including sulfur metabolism and antioxidant genes.
- Why it matters: Understanding how crops respond to multiple environmental stresses is crucial for improving resilience and yield stability under changing climate conditions.
- What they did: A multi-omics approach analyzed pea leaves under sulfur deficiency alone or combined with moderate water deficit, revealing gene and protein regulation changes, including 20 genes linked to reactive oxygen species responses.
- The result: The study found increased glutathione S-transferase activity and proteins encoded by genes with no transcriptional change, suggesting complex molecular adjustments that help limit oxidative damage during combined stress.
