The compositions and methods disclosed relate to DNA compositions, plant cells, seeds, plant parts that relate to maize plants with increased grain yield trait. Also provided are assays for detecting the presence of the maize DP-202216-6 event based on the DNA sequence of the recombinant construct inserted into the maize genome and the DNA sequences flanking the insertion site. Kits and conditions useful in conducting the assays are provided.

Genes, constructs and maize event DP-202216-6

Methods for modulating plants using optimized ZmSAUR down-regulation constructs are disclosed. Also disclosed are nucleotide sequences, constructs, vectors, and modified plant cells, as well as transgenic plants displaying increased seed and/or biomass yield, improved tolerance to abiotic stress such as drought or high plant density, improved nitrogen utilization efficiency, increased ear tissue growth or kernel number.

Down-regulation of auxin responsive genes for improved plant performance

The invention provides isolated floral transition nucleic acids and their encoded proteins. The present invention provides methods and compositions relating to altering floral transition in plants. The invention further provides regulatory elements, recombinant expression cassettes, host cells and transgenic plants.

Floral transition genes in maize and uses thereof

The invention provides isolated floral transition nucleic acids and their encoded proteins. The present invention provides methods and compositions relating to altering floral transition in plants. The invention further provides regulatory elements, recombinant expression cassettes, host cells, and transgenic plants.

An isolated polynucleotide encoding a delayed flowering gene (DLF1) is provided, as is the isolated DLF1 protein, peptide portions thereof, and functional fragments of the DLF1. Also provided is a transgenic plant, which contains in its genome a transgene containing the polynucleotide encoding the DLF1 protein, or a nucleotide sequence complementary to the encoding polynucleotide. In addition, methods of identifying a nucleotide sequence and/or a heterologous protein that is specifically bound by the DLF1 protein, methods of using the isolated polynucleotide (or encoded polypeptide), for example, to modulate plant cell growth and/or development, are provided.

Delayed flowering time gene (DLF1) in maize and uses thereof

This invention relates to an isolated nucleic acid fragment encoding floral development proteins, more specifically FT, TFL or Ap3 homologs. The invention also relates to the construction of a recombinant DNA construct encoding all or a portion of the floral development proteins, in sense or antisense orientation, wherein expression of the recombinant DNA construct results in production of altered levels of the FT, TFL or Ap3 homologs in a transformed host cell.

Floral development genes

This invention relates to an isolated nucleic acid fragment encoding a reproduction protein. The invention also relates to the construction of a chimeric gene encoding all or a portion of the reproduction protein, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the reproduction protein in a transformed host cell. The invention also provides isolated transcriptional regulatory elements and polynucleotides associated therewith.

Plant reproduction polynucleotides and methods of use

The present invention provides polynucleotides and related polypeptides of the protein ZMNAM isolated from maize endosperm. The invention provides genomic sequence for the ZMNAM gene. ZMNAM is a novel gene and is regulated by gene-specific imprinting. ZMNAM expression is endosperm-specific and expressed throughout the endosperm development, peaking at 25 DAP. Genomic imprinting has been implicated to play a role in endosperm development. Genes regulated by allele-specific imprinting are suspected to be non-essential to seed development. Gene-specific imprinting however, regulates developmentally important genes. The ZMNAM gene, a putative transcriptional factor, may play an important role in endosperm development, which may further affect kernel size, plant vigor during germination and at the early seedling stage.
