  • Patent number: 11330776
    Abstract: The disclosure pertains to methods and compositions for the rapid and efficient transformation of plants. The disclosure further provides methods for producing a transgenic plant, comprising (a) transforming a cell of an explant with an expression construct comprising (i) a nucleotide sequence encoding a WUS/WOX homeobox polypeptide; (ii) a nucleotide sequence encoding a polypeptide comprising two AP2-DNA binding domains; or (iii) a combination of (i) and (ii); and (b) allowing expression of the polypeptide of (a) in each transformed cell to form a regenerable plant structure in the absence of exogenous cytokinin, wherein no callus is formed; and (c) germinating the regenerable plant structure to form the transgenic plant. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
    Type: Grant
    Filed: August 26, 2016
    Date of Patent: May 17, 2022

  • Patent number: 10278345
    Abstract: Methods for preserving viability of plant tissues such as plant embryos are provided herein. Also included are methods for storing genomic DNA and/or molecular marker assay materials in an oil bilayer as part of a high-throughput molecular characterization system. Moreover, plant embryos may be treated while in an oil matrix. The treatment may include chromosome doubling, Agrobacterium-mediated transformation, or herbicide selection as part of an embryo rescue process.

  • Publication number: 20170240911
    Abstract: Methods and compositions for targeting the insertion of a polynucleotide of interest into a specific chromosomal site in the genome of a plant cell using bacteria-mediated transformation methods are provided. The methods include providing a plant cell with at least one Transfer Cassette comprising in operable linkage a least one polynucleotide construct and at least one recombinase construct, and optionally at least one cell proliferation factor construct. Compositions provided include plant cells, plants or seeds having a polynucleotide of interest inserted at a specific chromosomal site.
