  • Publication number: 20130091606
    Abstract: The present invention relates to a method of Agrobaterium-based transformation of a plant comprising: generating a callus explant by, performing callus induction and maintenance in a plant in at least a first solution comprising less than about 100 mg/l of inositol; subjecting the callus explant to a cold treatment in a second solution comprising glutamine; and co-cultivating the callus explant with an Agrobacterium in a third solution comprising glutamine. The present invention also relates to a callus induction medium and/or callus maintenance medium, comprising: less than about 100 mg/l of inositol, and optionally at least one constituent selected from the group consisting of: an N6 salt or any plant culture media, proline, casein hydrolysate, a B-Vitamin, maltose, phytagel, 2,4-D, BAP and/or other plant growth regulators/hormones.

  • Patent number: 8022271
    Abstract: The present invention provides novel expression control elements and methods for expressing a heterologous nucleotide sequence of interest in plants. Isolated nucleic acids, expression cassettes and vectors comprising the expression control elements are provided. Also provided are transformed plants, plant tissues, plant cells, plant seed, and the like, comprising the isolated nucleic acids, expression cassettes and vectors of the invention. Further provided are methods of expressing a heterologous nucleotide sequence of interest in a plant, plant tissue, plant cell, and the like.

  • Publication number: 20110138495
    Abstract: Methods and compositions comprising an expression construct and a suppressor of posttranscriptional gene silencing construct are described. The expression construct and suppressor construct may comprise a viral amplicon. The expression construct may comprise fusing the target gene to the 3? and/or 5? end of a gene encoding a transit peptide sequence or a signaling peptide sequences. The transit or signal peptide sequence directs the target gene product to a subcellular location. Methods comprise the production of several heterologous proteins in a single plant. The invention comprises methods for plant production and protein harvest that will yield useful amounts of the desired protein(s) in as little as one to two weeks after the initiation of the production cycle. Methods for the inoculation of recipient plants by spraying with recombinant Agrobacterium suspensions containing the constructs of interest are taught.
