Process for increasing free pool lysine content in maize

摘要

The present invention is directed to a process for increasing the free pool lysine content of individual maize seeds and for increasing the average free pool lysine content of seeds produced by a maize plant. The process, in general, comprises initiating callus from maize tissue, selecting for callus tissue resistant to S-2-aminoethyl-L-cysteine, and regenerating plants from the selected callus. In addition, the callus may be maintained before or during the selection scheme, or in place of the selection scheme.
