摘要:
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.
摘要:
Compositions and methods for protecting a plant from an insect pest are provided. In particular, nucleic acid sequences encoding insect protoxins modified to comprise at least one proteolytic activation site that is sensitive to a plant protease or an insect gut protease are provided. Cleavage of the modified protoxin at the proteolytic activation site by a protease produces an active insect toxin. Methods of using the modified insect protoxin nucleic acid sequences and the polypeptides they encode to protect a plant from an insect pest are provided. Particular embodiments of the invention further provide modified insect protoxin compositions and formulations, expression cassettes, and transformed plants, plant cells, and seeds.

摘要:
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.
摘要:
Methods and compositions for expressing a polynucleotide of interest are provided. Compositions comprise an enhancer domain set forth in SEQ ID NO: 1, 10, 15, or 16 and active variants and fragments thereof. Further provided are DNA constructs comprising at least one transcriptional enhancer sequence comprising the nucleotide sequence set forth in SEQ ID NO:1, 10, 15, or 16 or an active variant or fragment thereof, operably linked to a heterologous promoter. Such chimeric transcription regulatory regions can be operably linked any polynucleotide of interest. Further provided are cells, plants, plant parts, and germplasm comprising the DNA construct. Methods of using the chimeric transcriptional regulatory region are also provided. In specific embodiments, methods of expressing a polynucleotide of interest, including for example, sequences that confer tolerance to herbicides, and methods to select a cell having the DNA construct are provided.
