Vitamin C in Plants: From Functions to Biofortification

Area of Science:

• Plant Physiology
• Biochemistry
• Nutritional Science

Background:

• Vitamin C (l-ascorbic acid) functions as a potent antioxidant and essential enzyme cofactor in both plants and humans.
• Humans cannot synthesize vitamin C due to a non-functional gene, necessitating dietary intake primarily from plants.
• Understanding plant vitamin C metabolism is crucial for improving human nutrition through crop enhancement.

Purpose of the Study:

• To review the diverse roles of vitamin C in plant physiology.
• To analyze the regulation of vitamin C content in plants via biosynthetic and recycling pathways.
• To explore strategies for increasing vitamin C levels in crops for enhanced nutritional value and stress resistance.

Main Methods:

• Literature review of plant physiology and biochemistry studies.
• Analysis of vitamin C biosynthetic and recycling pathways in plants.
• Examination of crop breeding and genetic modification strategies for vitamin C enhancement.

Main Results:

• Vitamin C plays multifaceted roles in plants, including antioxidant defense and metabolic regulation.
• Plant vitamin C content is tightly regulated through complex biosynthetic and recycling mechanisms.
• Strategies exist to increase crop vitamin C, offering dual benefits for human health and plant resilience.

Conclusions:

• Enhancing vitamin C in crops is a viable strategy to improve human health and nutritional security.
• Further research into plant vitamin C metabolism can unlock potential for biofortification.
• Increased vitamin C content may also confer enhanced stress tolerance in agricultural crops.
