CHIMERIC GENES AND METHOD FOR INCREASING THE THREONINE CONTENT OF THE SEEDS OF PLANTS.

摘要

A chimeric gene encoding a bifunctional feedback-insensitive aspartokinase-homoserine dehydrogenase (AK-HDH), is operably linked to a plant chloroplast transit sequence, and to plant seed-specific regulatory sequences. The chimeric gene is transformed into plants wherein increased levels of free threonine accumulate in the seeds.
