Abstract

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