PRODUCTION OF ASCORBIC ACID IN PLANTS

摘要

The present invention relates to a polynucleotide in isolated form, which polynucleotide codes for a protein with the activity of the enzyme L-galactono-gamma-lactone dehydrogenase, which polynucleotide comprises at least the L-galactono-gamma-lactone dehydrogenase activity-determining parts of the coding part of the sequence or a sequence derived therefrom on the basis of the degeneration of the genetic code. The invention further relates to the use of the polynucleotide in the production of transgenic plants, plant cells, or other eukaryotic cells.
