摘要：
The present invention describes an alternative approach to increase methionine (Met) production in eukaryotes, namely by the insertion of components of a sulfur-metabolic pathway in organisms where the pathway does not exist or has not clearly been identified. The invention describes methods for the use of polynucleotides that encode functional cysteine dioxygenase (CDO) alone or CDO and sulfinoalanine decarboxylase (SAD) polypeptides in plants to increase Met production. The preferred embodiment of the invention is in plants but other organisms may be used. Changes in Met availability will improve nutritional value of the crop.
