Abstract excerpt

KEY MESSAGE: Targeted mutations in five carotenoid catabolism genes failed to boost carotenoid accumulation in rice seeds, but produced dwarf and high tillering mutants when OsCCD7 gene was knocked out. Carotenoids play an important role in human diet as a source of vitamin A. Rice is a major staple food in Asia, but does not accumulate carotenoids in the endosperm because of the low carotenoid biosynthesis or...
