摘要： Compositions and methods are provided for the introduction and the regulated expression of genes in plants. Compositions include promoter constructs that provide a level of activity useful for the regulated expression of site-specific recombinases, while avoiding premature excision. Further provided are isolated polynucleotides encoding novel babyboom polypeptides, expression cassettes, and plants comprising the same. Methods for the introduction of genes into plants are provided, including methods for plastid transformation and methods for the transformation of tissues from mature seeds and leaves.

摘要： Automated, high-throughput and multiplexed methods for clonal plant production from maternal or paternal derived cellular structures including embryos and microspores, using morphogenic factors to produce plants are disclosed. Large scale and rapid clonal propagation methods facilitate increased efficiency in producing doubled haploid plants for breeding and for trait introgression purposes.

摘要： Methods and compositions are provided for the improvement of homology-directed repair of a double strand break in a plant cell, via the use of a polynucleotide comprising sequences homologous to the target site. 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 polynucleotide repair template.

摘要： Methods and compositions are provided for the transient expression and activity of site-specific DNA modifying agent, morphogenic factors or developmental genes, either alone or in combination for eukaryotic cells. The morphogenic factor and DNA modifying agent may be provided to the same cell or to a different cell than that which was originally transformed. The morphogenic factor, or the double-strand-break-inducing agent, may further comprise a cell penetrating peptide. Exogenously provided DNA modifying agents and/or morphogenic factors need not be segregated away in future generations due to transient activities in the desired cell.

摘要： 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.

摘要： Compositions and methods are provided for the use of pollen-inhibitor genes and/or color marker genes in accelerated trait introgression. Compositions and methods are also provided for introducing a pollen-inhibitor gene and/or a color marker gene in close proximity to a trait locus of interest. Breeding methods and methods for selecting plants comprising a trait locus of interest in close proximity to at least one pollen-inhibitor gene and/or color marker gene are also disclosed. The methods and compositions employ at least one pollen-inhibitor gene and/or color marker gene to provide an effective system for accelerated trait introgression in the genome of a plant.
