Abstract

This invention relates to an isolated nucleic acid fragment encoding a GTP cyclohydrolase II/3,4-dihydroxy-2-butanone-4-phosphate synthase protein. The invention also relates to the construction of a chimeric gene encoding all or a substantial portion of the protein, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the protein in a transformed host cell.
