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.

Claims13

Dependent claims

An isolated polynucleotide comprising:

(a) a nucleotide sequence encoding a polypeptide having GTP cyclohydrolase II/3,4-dihydroxy-2-butanone-4-phosphate synthase activity, wherein the amino acid sequence of the polypeptide and the amino acid sequence of SEQ ID NO:66 have at least 80% sequence identity, or
(b) the complement of the nucleotide sequence, wherein the complement and the nucleotide sequence contain the same number of nucleotides and are 100% complementary.

Dependencies are inferred from the claim text.
