Abstract:
1. A transgenic maize plant comprising in its genome transgenic DNA encoding an antisense sequence complementary to all or a portion of a 19 kD or 22 kDa alpha-zein messenger RNA (mRNA) and a transgenic DNA for the expression of lysine insensitive aspartate kinase (AK) or dihydrodipicolinic acid synthase (DHDPS), and/or transgenic DNA encoding an antisense sequence complementary to all or a portion of a maize lysine-ketoglutarate reductase (LKR) mRNA and a saccharopine dehydrogenase (SDH) mRNA, whereby expression of said transgenic DNA results in a synergistically increased free lysine content of seed of said transgenic maize plant.
