  • Publication number: 20210323923
    Abstract: Methods for preparing 5-fluoro-6-(bromo or chloro)picloram analogs, or derivatives thereof, from picloram acid, picloram ester, or the nitrile analog of picloram are provided. The methods include chemical process steps that: (1) introduce a phthaloyl group onto the 4-amino substituent of picloram acid, picloram ester, or the nitrile analog of picloram, (2) add 2 fluorine atoms at the 5,6-positions of the pyridine ring using halex fluorination chemistry, (3) remove the phthaloyl group, hydrolyze the ester or nitrile substituent, and add chlorine or bromine to the 6-position by treatment with an acid and water, and finally, (4) esterify the 5-fluoro-6-(bromo or chloro)picloram acid produced in step (3) to a 5-fluoro-6-(bromo or chloro)picloram ester.

  • Publication number: 20210214745
    Abstract: The invention provides synthetic nucleic acid sequences encoding proteins of interest that are particularly adapted to express well in plants. The claimed synthetic sequences utilize plant-optimized codons roughly in the same frequency at which they are utilized, on average, in genes naturally occurring in the plant species. The invention further includes synthetic DNA sequence for herbicide tolerance, water and/or heat stress tolerance, healthy oil modifications and for transformation marker genes and selectable marker genes are used. DNA construct and transgenic plants containing the synthetic sequences are taught as are methods and compositions for using the plants in agriculture.

  • Patent number: 11008578
    Abstract: A method for producing a transgenic plant includes providing a nucleic acid molecule comprising at least two regions of nucleic acid sequence that lack sequence homology with genomic DNA of the plant cell, and at least two zinc finger nuclease recognition sites, wherein the at least two regions of nucleic acid sequence that lack sequence homology with genomic DNA of the plant cell flank the at least two zinc finger nuclease recognition sites. A plant cell or tissue having the nucleic acid molecule stably integrated into the genome of the plant cell is transformed. A plant is regenerated from the plant cell. Transgenic plants are produced by the method. Seeds are produced by the transgenic plants.
