Sulfur deficiency in grapevines causes a massive buildup of nitrogen-rich amino acids and reduces water use efficiency, especially under high nitrogen conditions.
- Why it matters: Understanding how nutrient deficiencies affect grapevine metabolism is crucial for maintaining grape quality and crop resilience amid changing environmental conditions.
- What they did: Using non-targeted metabolomics and ionomics, the study examined grapevines under controlled sulfur and nitrogen levels, revealing distinct metabolic responses to isolated and combined deficiencies.
- The result: Findings suggest that managing sulfur and nitrogen together can mitigate metabolic imbalances and improve water use efficiency, informing nutrient management strategies for climate resilience.
