Abstract: Vitamins are vital nutrients that plants and animals require in limited amounts, including A, B1, B2, B3, B5, B6, B7, B9, B12, C, D, E and K. Human cannot synthesize the compounds in sufficient quantities, and they must be obtained from the diet, especially from plant foods. Vitamin deficiency is still prevalent in large population across the world, and closely associated with increasing risks of diseases. Scientists have made great efforts on the enhancement of vitamins in plants through biofortification to tackle this global problem. This review summarized the progress of vitamin metabolism and fortification in plants, and sheds light on the trends in breeding by molecular design for vitamin-enriched crops.

Key words: vitamin, metabolism, plant, biofortification
