Elevating methionine levels in plants alters development, stress responses, and epigenetic regulation, but is constrained by the plant’s metabolic control mechanisms.
- Why it matters: Understanding how plants regulate methionine is crucial for improving crop nutritional value and stress resilience, addressing limitations in biofortification efforts.
- What they did: The review synthesizes evidence from genetic and metabolic studies, showing that despite high flux through the Met/SAM pathway, Met pools stay low, and increasing Met impacts growth, metabolism, and epigenetics.
- The result: Findings reveal that plants restrict Met to maintain metabolic and epigenetic balance, which complicates biofortification strategies but offers insights into optimizing nutritional and stress-tolerance traits.
