carotenoid-biosynthesis
Carotenoid biosynthesis is the metabolic pathway by which plants produce yellow, orange, and red pigments including carotenes and xanthophylls from isoprenoid precursors. These pigments serve critical functions in plants beyond coloration, acting as accessory light-harvesting molecules in photosynthesis, photoprotective agents that dissipate excess light energy, and precursors to signaling compounds such as abscisic acid and strigolactones. Understanding and manipulating this pathway has broad implications for crop nutritional quality, stress tolerance, and the engineering of plants with enhanced pigment profiles.
