Methods and compositions for modulating plant meristems. Methods are provided for modulating fea3 and/or Fcp1 genomic locus in a host plant or plant cell to improve agronomic characteristics such as kernel number.

Methods and compositions to increase yield through modifications of FEA3 genomic locus and associated ligands

Compositions and methods for obtaining plant cells with modified Ht1 nucleotide sequences, modified NLB18 sequences, or both, are provided herein. The methods involve introducing double-strand breaks into the maize genome in an endogenous Ht1 encoding sequence, an endogenous NLB18 encoding sequence, or both, to modify the genomic sequence in order to enhance northern leaf blight resistance of a plant produced from the plant cell. Further provided are methods that introduce resistant alleles of Ht1 and/or NLB18 into specific sites in the genome. Plants produced by the plant cells, and seeds produced from the plants are also included. Guide polynucleotides are also provided for the use of the CRISPR-Cas system in inducing double strand breaks.

Generating northern leaf blight resistant maize

The present disclosure involves the production of Waxy maize. Compositions and methods are provided for knocking out expression of the Waxy (Wx1) gene in maize by making double strand breaks at one or more target sites in an endogenous WX1 encoding sequence. Some methods employ one or more guide polynucleotides and a Cas endonuclease, wherein Cas endonuclease is guided by the one or more guide polynucleotides to recognize and introduce double strand breaks at specific target sites in and around the Wx1 gene. Also provided are compositions and methods for the production of Waxy maize plant cells, plant explants, seeds and grain.

Waxy corn

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 enzymes of the ACC synthase family are used in producing ethylene. Nucleotide and polypeptide sequences of ACC synthases are provided along with knockout plant cells having inhibition in expression and/or activity in an ACC synthase and knockout plants displaying a staygreen phenotype, a male sterility phenotype, or an inhibition in ethylene production. Methods for modulating staygreen potential in plants, methods for modulating sterility in plants, and methods for inhibiting ethylene production in plants are also provided.

Engineering single-gene-controlled staygreen potential into plants

The present invention is directed to compositions and methods for altering the levels of seed proteins in cereal grain. The invention is directed to the alteration of seed protein levels in plant grain, resulting in grain with increased digestibility/nutrient availability, improved amino acid composition/nutritional value, increased response to feed processing, improved silage quality, and increased efficiency of wet milling.

Grain quality through altered expression of seed proteins

The enzymes of the ACC synthase family are used in producing ethylene. Nucleotide and polypeptide sequences of ACC synthases, namely ACS2, ACS6, and ACS7 from, are provided. Knockout plant cells having inhibition in expression and/or activity in an ACC synthase such as ACS2, ACS6, or ACS7 and knockout plants displaying a staygreen phenotype, a male sterility phenotype, or an inhibition in ethylene production are also provided, as are seeds obtained from such plants. Methods for modulating staygreen potential in plants, methods for modulating sterility in plants, and methods for inhibiting ethylene production in plants are also provided.

[object Object]

The present invention provides polynucleotides and related polypeptides of the class of genes involved in maize secondary wall (ZmSCW) formation. The invention provides genomic sequence for the ZmSCW genes. ZmSCW are responsible for controlling plant growth, secondary cell wall development and yield in crop plants.

Secondary wall forming genes from maize and uses thereof

Compositions and methods for the alteration of the disulfide status of plant proteins are provided. Novel nucleotide molecules, comprising nucleotide sequences for thioredoxin h and NADPH-thioredoxin reductase, and the proteins encoded thereby are provided. The nucleotide sequences can be used to transform plants alone or in combination with other sequences, such as sequences encoding NADPH generating enzymes, to manipulate the thioredoxin h system and alter the protein disulfide status in plants. Transformed plants, plant cells, plant tissues, seed and grain are provided.
