Abstract: The field is molecular biology, and more specifically, methods for chromosomal engineering of multiple native genes, such as disease resistance genes in a genomic locus using site-specific editing to produce plants. Also described herein are methods of generating heterologous genomic locus in a plant that comprises a plurality of intraspecies polynucleotide sequences.

Abstract: The field is molecular biology, and more specifically, methods for editing the genome of a plant cell to identify causal alleles of a desired trait or to fine map a desired trait to small region of the genome for gene identification.

Abstract: The disclosure provides plant, plant parts, plant cells, seed and grain containing a targeted genetic modification that inserts an inverted repeat sequence into a gene. The disclosure further provides hybrid plants that contain the inverted repeat sequence in a single allele of the gene. Further provided are methods for decreasing expression of a gene encoding a polypeptide of interest in a hybrid plant by crossing a plant comprising the targeted genetic modification with a plant not comprising the genetic modification to produce a hybrid plant that contains the inverted repeat sequence in a single allele of the gene.

Abstract: Methods and compositions to modulate plant stature including plant height, ear height, planting density and other agronomic characteristics are disclosed. The disclosure further discloses compositions, polynucleotide constructs, transformed host cells, plants and seeds exhibiting altered stature characteristics or produce plants that exhibit altered stature parameters.

Abstract: Transgenic compositions and methods reduce the expression of endogenous ACC oxidase genes to improve an agronomic characteristic of a crop plant, which may be maize. Yield increase and drought tolerance due to reduction in the endogenous ACC oxidase levels are observed. ACC oxidase genes are identified in maize, rice, and Arabidopsis genomes.
