  • Process for the production of plants with enhanced growth characteristics
    Patent number: 6846969
    Abstract: The invention is drawn to plant cell transformation with a nucleic acid construct comprising a prokaryotic ammonium-specific asparagine synthetase, type A, coding sequence, operably linked to a chloroplast transit peptide-encoding sequence, wherein said plant cells also contain a nucleic acid construct comprising a chloroplastic glutamine synthetase coding sequence in antisense orientation. Plant cells containing both nucleic acid constructs, and plants regenerated therefrom, exhibit improved growth characteristics.

  • 2,4-diamino-1,3,5-triazines, processes for their preparation and their use as herbicides and plant growth regulators
    Patent number: 6239071
    Abstract: Compounds of the formula (I) and their salts in which R1 is optionally substituted (C1-C6)alkyl or optionally substituted phenyl, A is an optionally substituted hydrocarbon diradical and R2, R3, R4, R5, X and n are as defined in claim 1, are suitable as herbicides and plant growth regulators. The compounds (I) can be prepared according to processes as claimed in claim 6 by means of intermediates which are novel in some cases, e.g. of the formula (IV) as claimed in claim 10.
