摘要： Compositions and methods are provided for genome modification of a target sequence in the genome of a plant or plant cell. The methods and compositions employ a guide RNA/Cas endonuclease system to provide an effective system for modifying or altering target sites within the genome of a plant, plant cell or seed. Also provided are compositions and methods employing a guide polynucleotide/Cas endonuclease system for genome modification of a nucleotide sequence in the genome of a cell or organism, for gene editing, and/or for inserting or deleting a polynucleotide of interest into or from the genome of a cell or organism. Once a genomic target site is identified, a variety of methods can be employed to further modify the target sites such that they contain a variety of polynucleotides of interest. Breeding methods and methods for selecting plants utilizing a two component RNA guide and Cas endonuclease system are also disclosed. Compositions and methods are also provided for editing a nucleotide sequence in the genome of a cell.

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： 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.

摘要： Compositions and methods useful in identifying and/or selecting maize plants that have anthracnose stalk rot resistance are provided herein. The resistance may be newly conferred or enhanced relative to a control plant. The methods use maize markers on chromosome 10 to identify, select and/or construct resistant plants. Maize plants generated by the methods also provided.

摘要： The invention relates to gene expression regulatory sequences, specifically introns that act as enhancers of gene expression, the promoter and terminator sequences endogenously associated with these introns. Presence of these intronic enhancer sequences in proximity to promoter sequences leads to enhancement of gene expression. Methods of finding such new intronic enhancer sequences and using them to generate transgenic plants are also described.

摘要： The present invention is directed to perfluoroelastomer compounds comprising carbon black having a particle size of 100 nm or greater; a mineral filler selected from the group consisting of titanium dioxide, barium sulfate, or a combination of these; a cure site monomer; and a curing agent. These perfluoroelastomer compounds, when cured into articles, exhibit desirable compression stress relaxation properties.
