Compositions and methods for increasing carotenoid levels and carotenoid half-life in plants are provided. The methods involve transforming organisms with nucleic acid sequences encoding enzymes associated with carotenoid biosynthesis and tocopherol and tocotrienols. In particular, the nucleic acid sequences are useful for preparing plants and microorganisms that possess increased beta-carotene levels and half-life. Thus, transformed bacteria, plants, plant cells, plant tissues and seeds are provided. The sequences find use in the construction of expression vectors for subsequent transformation into organisms of interest including plants, particularly sorghum. |
