Abstract
A method is provided for increasing the level of free L-lysine in a plant comprising: (a) introducing a foreign gene into the cells of a plant tissue source; and (b) expressing said foreign gene in said cells, wherein a first DNA sequence of said gene encodes dihydrodipicolinic acid synthase (DHDPS) which is substantially resistant to feedback inhibition by endogenously-produced free L-lysine.
