Tetrahydrofolate metabolism enzymes

摘要

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