ABSTRACT:
A chimeric gene construct comprising a DNA sequence encoding an enzyme having aspartate kinase (AK) activity is provided, which is capable of expression in plant cells with subsequent increased production of threonine. Transgenic plants containing in their cells said chimeric gene overproduce threonine and transgenic plants containing in their cells said chimeric gene and a second chimeric gene comprising a DNA sequence coding for an enzyme having dihydrodipicolinate synthase (DHPS) activity, overproduce both threonine and lysine. The transgenic plants are resistant to lysine and threonine, to derivatives thereof and to selective inhibitors of the plant enzymes DHPS or AK, and thus these compounds may be used as selective herbicides in locus where the transgenic plants are cultivated.
