Methods and compositions for modulating development and defense responses are provided. Nucleotide sequences encoding defensin proteins are provided. The sequences can be used in expression cassettes for modulating development, developmental pathways, and defense responses. Transformed plants, plant cells, tissues, and seed are also provided.

Defensin polynucleotides and methods of use

Methods and compositions are provided related to improved plants that are tolerant to more than one herbicide. Particularly, the invention provides plants that are tolerant of glyphosate and are tolerant to at least one ALS inhibitor, and methods of use thereof. The glyphosate/ALS inhibitor-tolerant plants comprise a polynucleotide that encodes a polypeptide that confers tolerance to glyphosate and a polynucleotide that encodes an ALS inhibitor-tolerant polypeptide. In specific embodiments, a plant of the invention expresses a GAT polypeptide and an HRA polypeptide. Methods to control weeds, improve plant yield, and increase transformation efficiencies are provided.

Methods and compositions for providing tolerance to multiple herbicides

Methods and compositions for expressing an herbicide-tolerant polynucleotide

The present invention provides compositions and methods for isolated nucleic acid molecules encoding orally activepesticidal polypeptides. Compositions include novel nucleotide sequences encodingpesticidal polypeptides, and biologically active variants thereof. Further provided are methods for modulating the pesticide resistance of plants using the nucleotide sequences disclosed herein. One method comprises stably transforming into the genome of a plant cell a nucleotide sequence of the present invention operably linked to a heterologous promoter and regenerating a stably transformed plant that expresses the nucleotide sequence. An additional method comprises incorporating a nucleotide sequence of the present invention operably linked to a heterologous promoter into a microorganism and applying said microorganism to the environment of a plant.

Isolated nucleic acid molecules encoding orally active androctonus amoreuxi pesticidal biopeptides

The present invention is directed to nucleic acid molecules tat encode defensive polypeptides and methods of their use in enhancing disease resistance of a plant to a fungal pathogen. Vectors, expression cassettes, viruses, cells, and plants comprising a nucleotide sequence of the invention are farther provided.

RHIZOC3 nucleic acid molecules

The present invention is directed to nucleic acid molecules that encode Fus6 defensive polypeptides and methods of their use in enhancing disease resistance of a plant to a fungal pathogen. Vectors, expression cassettes, viruses, cells, and plants comprising a nucleotide sequence of the invention are further provided.

FUS6 nucleic acid molecules and methods of their use in enhancing disease resistance in plants

The methods and compositions of the present invention find use in impacting microbial pathogens and in enhancing disease resistance to pathogens, particularly by plants. The compositions of the invention include polypeptides that possess antimicrobial properties, particularly fungicidal properties, and the encoding nucleic acid molecules. The polypeptides of the invention are isolated from the hemolymph and fat bodies of insect larvae induced by injection of plant pathogenic fungi. Further provided are plant cells, plants, and seed thereof, transformed with the nucleic acid molecules of the invention so as to confer disease resistance on the plant.

Rhizoc3 antimicrobial polypeptides and their uses

This invention relates to an isolated nucleic acid fragment encoding scorpion toxins that are K-channel agonists. The invention also relates to the construction of a chimeric gene encoding all or a portion of the K-channel agonists, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the K-channel agonists in a transformed host cell.
