The present invention provides polynucleotides and related polypeptides of the protein GS. The invention provides genomic sequence for the GS gene. GS is responsible for controlling nitrogen utilization efficiency in plants. Glutamine synthase sequences are provided for improving grain yield and plant growth. The invention further provides recombinant expression cassettes, host cells and transgenic plants.

Manipulation of glutamine symthetases (GS) to improve nitrogen use efficiency and grain yield in higher plants

The present invention provides polynucleotides and related polypeptides of the ZmARGOS gene family. The invention provides genomic sequence for the ZmARGOS genes. ZmARGOS is responsible for controlling plant growth, organ size and yield in crop plants.

Maize genes for controlling plant growth and organ size and their use in improving crop plants

Isolated polynucleotides and polypeptides and recombinant DNA constructs useful for conferring drought tolerance, compositions (such as plants or seeds) comprising these recombinant DNA constructs, and methods utilizing these recombinant DNA constructs. The recombinant DNA construct comprises a polynucleotide operably linked to a promoter that is functional in a plant, wherein said polynucleotide encodes a PRE2 polypeptide.

Plants with improved agronomic traits

The present invention provides polynucleotides and related polypeptides of the protein AMT. The invention provides genomic sequence for the AMT gene. AMT is responsible for controlling nitrogen utilization efficiency in plants.

Manipulation of ammonium transporters (AMTs) to improve NUE in higher plants

The present invention provides polynucleotides and related polypeptides (SEQ ID NO: 11 and 44) of the ZmARGOS (Auxin-Regulated Gene involved in Organ Size) gene family. The invention provides genomic sequence for the ZmARGOS genes. ZmARGOS is responsible for controlling plant growth, organ size and yield in crop plants. Transgenic plants expressing ZmARGOS show a positive impact on biomass accumulation and rate of maize plant growth, as well as an increase in organ size. These maize genes will find utility for enhancing agronomic traits in maize (and other crops).
