  • Patent number: 11365369
    Abstract: The present invention relates to methods of producing industrial products from plant lipids, particularly from vegetative parts of plants.

  • Publication number: 20200385822
    Abstract: The present invention relates generally to the field of recombinant fatty acid synthesis, particularly in transgenic plants. The application describes genes involved in fatty acid synthesis and provides methods and vectors for the manipulation of fatty acid composition of plant oils. In particular, the invention provides constructs for achieving the integration of multiple heterologous genes involved in fatty acid synthesis into the plant genome, such that the resulting plants produce altered levels of polyunsaturated fatty acids. Also described are methods for enhancing the expression of fatty acid biosynthesis enzymes by co-expressing a silencing suppressor within the plant storage organ.

  • Publication number: 20200315115
    Abstract: The invention provides an improved method for transformation of sorghum and the production of genetically modified sorghum. In particular, methods and means are described for the production of high quality, transformable sorghum plant cells which are maintained in culture for longer duration without losing their regenerative potential and their use for genetic transformation. The method also describes the use of improved media for efficient plant regeneration from transformed plant cells, thereby providing significant improvement in the stable transformation frequency of sorghum.
