Genetic manipulation of carotenoid biosynthesis: strategies, problems and achievements.
Carotenoids, some of which are provitamin A, have a range of diverse biological functions and actions, especially in relation to human health. For example, carotenoids are known to be crucial for normal vision and have been associated with reducing the risk of several degenerative diseases including cancer. The putative advantage of modifying and engineering the carotenoid biosynthetic pathways is obvious: to provide sources for the isolation of desired carotenoids or to generate food plants with increased carotenoid content. This article reviews the studies of carotenoid production in heterologous microorganisms and the engineering of crop plants using manipulated carotenoid biosynthesis.[1]References
