L-phenylalanine induces cutin and wax biosynthesis in muskmelon fruit epidermis via fatty acid and triterpenoid pathways

Key Points

• Cutin and wax biosynthesis increased significantly in muskmelon fruit epidermis after l-phenylalanine treatment, enhancing fruit protection.
• Increased levels of cutin and wax were observed in fruits treated with l-phenylalanine for two weeks, indicating metabolic activation.
• Analysis of fatty acid and triterpenoid pathways revealed critical roles in the biosynthesis process promoted by l-phenylalanine.
• These findings highlight potential agricultural practices that could improve fruit resistance and longevity through metabolic manipulation.
