  • Publication number: 20220307006
    Abstract: Methods and compositions are provided for the improvement of homology-directed repair of a double strand break in a plant cell, using concatemers of heterologous polynucleotides that are flanked by sequences capable of sequence hybridization with a guide RNA. In some aspects, the double strand break is created by an RNA-guided Cas endonuclease. The homology-directed repair of the double-strand break may include incorporation of a heterologous polynucleotide, for example a gene encoding a trait of agronomic importance. The homology-directed repair of the double-strand break may occur as a result of template-directed repair using a heterologous polynucleotide as a repair template.

  • Publication number: 20220251586
    Abstract: Compositions and methods are provided for stacking multiple independent transgenic loci into the genome of a plant. Compositions include plants, seeds or plant cells comprising at least one transgenic target site and at least one genomic locus of interest integrated at different genomic sites within a genomic window. Plant breeding techniques can be employed such that the transgenic target site and the genomic locus of interest can be bred together. In this way, multiple independent transgene integrations can be generated within a genomic window to create a complex trait locus. The complex trait locus is designed such that the transgenic target sites and/or genomic loci of interest can segregate independently of each other, thus providing the benefit of altering a complex trait locus by breeding-in and breeding-away specific elements. Various methods can also be employed to modify the target sites such that they contain a variety of polynucleotides of interest.

  • Publication number: 20220240467
    Abstract: Plant cell fate and development is altered by treating cells with cellular reprogramming factors. Embryogenesis inducing embryogenesis factor genes and/or morphogenic developmental genes are used as cellular reprogramming factors, specifically comprising polypeptides or polynucleotides encoding gene products for generating doubled haploids or haploid plants from gametes. Maize microspores treated by contacting the isolated cells with an exogenous purified, recombinant embryogenesis inducing embryogenesis factor gene products and/or morphogenic developmental gene polypeptide results in embryogenesis. The gametes of a maize plant develop into embryoids when transformed with a genetic construct including regulatory elements and structural genes capable of acting in a cascading fashion to alter cellular fate of plant cells. Embryogenesis factor proteins and/or developmental morphogenic proteins expressed from a genetic construct are used for ex situ treatment methods and for in planta cellular reprogramming.
