Abstract: Compositions and methods to modify at least one target locus in a plant cell are provided, which comprises providing a plant cell, a plant, or a plant part with one or more target loci and one or more donor loci, providing at least one cleaving site specific nuclease to produce a double strand break within the target loci, followed by non-homologous end joining of at least one donor locus within at least one target locus. Target loci, donor loci and nuclease loci used in these methods, and plant cells, plants and plant parts comprising these target loci, donor loci, nuclease loci and/or the recombined loci are also provided.

Abstract: Disclosed are methods for transformation of an androgenic-derived, haploid cell line with a site-specific nuclease. In some embodiments, the androgenic-derived, haploid cell line is a maize microspore-derived plant tissue culture. In addition, the disclosure provides a method for modifying, e.g., by mutating or targeting and integrating donor DNA into, a specific locus of a haploid or dihaploid tissue genome. The disclosure further provides methods for regenerating a whole plant from the haploid or dihaploid tissue that contains either the mutation at a specific genomic locus or a donor DNA integrated within a specific genomic locus may be obtained from the subject disclosure.

Abstract: Constructs for expressing herbicide tolerance genes, related plants, and related trait combinations, said constructs comprise a gene referred to herein as DSM-2 identified in Streptomyces coelicolor (A3). The DSM-2 protein is distantly related to PAT and BAR DSM-2 can be used as a transgenic trait to impart tolerance in plant cells and plants to the herbicidal molecules glufosinate, phosphinothricin, bialaphos, and/or the like. The subject invention also relates to combination of the subject herbicide tolerant crop (HTC) traits along with other HTC traits and/or insect resistance (IR) traits.
