Abstract

This invention relates to an isolated nucleic acid fragment encoding a carotenoid biosynthetic enzyme. The invention also relates to the construction of a chimeric gene encoding all or a portion of the carotenoid biosynthetic enzyme, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the carotenoid biosynthetic enzyme in a transformed host cell.
