Main Methods:

• Review of established and emerging research on plant vitamin biosynthesis.
• Analysis of metabolic engineering strategies applied to vitamin production in plants.
• Identification of knowledge gaps in plant vitamin metabolism and regulation.

Main Results:

• Significant progress has been made in elucidating pathways for provitamin A, vitamin C, and vitamin E.
• Metabolic engineering has successfully generated transgenic plants with elevated levels of these vitamins.
• Challenges remain in understanding vitamin regulation, storage, and interactions with other metabolic pathways.

Conclusions:

• Plant-based vitamin biosynthesis is a critical area for human nutrition.
• Metabolic engineering offers a powerful tool to enhance vitamin content in plants.
• Further research is needed to optimize and control vitamin levels for health and industrial applications.
