Abstract
Adequate consumption of carotenoids including lycopene, β-carotene, lutein, zeaxanthin, and astaxanthin have many benefits for human health. In plants, carotenoids are derived from isoprenoid precursors from the 2-C-methyl-d-erythritol 4-phosphate (MEP) pathway located in plastids. The MEP pathway is also required for the biosynthesis of chlorophyll, terpenoids, plant hormones, and other metabolites. Despite its complexity and difficulty, various strategies have been successfully used to improve the carotenoid biosynthesis in plants through metabolic engineering. Here, these metabolic engineering strategies are reviewed. In addition, the development of gene stacking technologies for carotenoid biosynthesis is evaluated. These technologies will expedite our efforts to bring the health benefits of carotenoids and other nutritional compounds to our diet.
