Gene involved in pyrimidine biosynthesis in plants

摘要

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