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