Elevating methionine levels in plants alters development, stress responses, and epigenetic marks, but often causes growth defects and stress hypersensitivity.
- Why it matters: Understanding how plants regulate low methionine levels is crucial for improving crop nutritional value and developing effective biofortification strategies, which are currently limited by these regulatory constraints.
- What they did: The review summarizes evidence that high flux through the Met/SAM pathway maintains low Met pools, and describes how genetic increases in Met affect plant growth, metabolism, and epigenetics, with some benefits and drawbacks.
- The result: Findings suggest that plants limit Met to control metabolic and epigenetic processes, which constrains biofortification efforts but also offers potential for moderate Met supplementation to enhance growth and stress tolerance.
