Gene Duplication in the Carotenoid Biosynthetic Pathway Preceded Evolution of the Grasses 1

Abstract

Despite ongoing research on carotenoid biosynthesis in model organisms, there is a paucity of information on pathway regulation operating in the grasses (Poaceae), which include plants of world-wide agronomic importance. As a result, efforts to either breed for or metabolically engineer improvements in carotenoid content or composition in cereal crops have… (More)
