The present disclosure provides compositions and methods for altering gibberellin (GA) content in corn or other cereal plants. Methods and compositions are also provided for altering the expression of genes related to gibberellin biosynthesis through suppression, mutagenesis and/or editing of specific subtypes of GA20 or GA3 oxidase genes. Modified plant cells and plants having a suppression element or mutation reducing the expression or activity of a GA oxidase gene are further provided comprising reduced gibberellin levels and improved characteristics, such as reduced plant height and increased lodging resistance, but without off-types.

Methods and compositions for short stature plants through manipulation of gibberellin metabolism to increase harvestable yield

The present invention provides recombinant DNA constructs, vectors and molecules comprising a polynucleotide sequence encoding a florigenic FT protein operably linked to a vegetative stage promoter, which may also be a meristem-preferred or meristem-specific promoter. Transgenic plants, plant cells and tissues, and plant parts are further provided comprising a polynucleotide sequence encoding a florigenic FT protein. Transgenic plants comprising a florigenic FT transgene may produce more bolls, siliques, fruits, nuts, or pods per node on the transgenic plant, particularly on the main stem of the plant, relative to a control or wild type plant. Methods are further provided for introducing a florigenic FT transgene into a plant, and planting transgenic FT plants in the field including at higher densities. Transgenic plants of the present invention may thus provide greater yield potential than wild type plants and may be planted at a higher density due to their altered plant architecture.

Compositions and methods for altering flowering and plant architecture to improve yield potential

The present disclosure provides compositions and methods for altering gibberellin (GA) content in corn or other cereal plants. Methods and compositions are also provided for altering the expression of genes related to gibberellin biosynthesis through editing of specific subtypes of GA20 oxidase genes to introduce an antisense sequence or segment into the gene. Modified plant cells and plants having a dominant allele reducing the expression or activity of one or more GA oxidase genes are further provided comprising reduced gibberellin levels and improved characteristics, such as reduced plant height and increased lodging resistance, but without off-types.

Methods and compositions for generating dominant short stature alleles using genome editing

A recombinant DNA construct is disclosed. When the recombinant DNA construct is expressed in a plant or a plant cell, endogenous HD-Zip class II proteins become less able to repress DNA transcription of the genes they typically regulate. The recombinant DNA construct can be expressed in plant cells to produce plants with enhanced phenotypes. Methods of making transgenic plants comprising the recombinant DNA construct, and plants produced thereby are also disclosed.

Interfering with HD-Zip transcription factor repression of gene expression to produce plants with enhanced traits

The present invention provides a method for altering the tryptophan content of a plant by introducing and expressing an isolated DNA segment encoding an anthranilate synthase in the cells of the plant. Transgenic plants transformed with an isolated DNA segment encoding an anthranilate synthase, as well as human or animal food, seeds and progeny derived from these plants, are also provided.
