摘要:
Methods and compositions for increasing a plant's resistance to an insect pest such as the corn rootworm are provided. Methods are provided for overexpression of Crw2, or variants thereof, in a host plant or plant cell to increase resistance to an insect pest in a plant such as maize. Methods are also provided for identifying variants of Crw2 that when incorporated into a plant via transgenic or traditional breeding means increase resistance to an insect pest in a plant such as maize. Also provided are methods for increasing resistance by overexpressing Crw1 and Crw2.
摘要:
The present disclosure provides compositions and methods for regulating expression of heterologous nucleotide sequences in a plant. Compositions include a novel nucleotide sequence for regulatory elements from Petunia Vein Clearing Virus. A method for expressing a heterologous nucleotide sequence in a plant using the regulatory element sequences disclosed herein is provided. The method comprises transforming a plant or plant cell with a nucleotide sequence operably linked to one of the regulatory elements of the present disclosure.
摘要:
Compositions and methods for controlling pests are provided. The methods involve transforming organisms with a nucleic acid sequence encoding an insecticidal protein. In particular, the nucleic acid sequences are useful for preparing plants and microorganisms that possess insecticidal activity. Thus, transformed bacteria, plants, plant cells, plant tissues and seeds are provided. Compositions are insecticidal nucleic acids and proteins of bacterial species. The sequences find use in the construction of expression vectors for subsequent transformation into organisms of interest including plants, as probes for the isolation of other homologous (or partially homologous) genes. The pesticidal proteins find use in controlling, inhibiting growth or killing Lepidopteran, Coleopteran, Dipteran, fungal, Hemipteran and nematode pest populations and for producing compositions with insecticidal activity.
摘要:
Nucleotide sequences, amino acid sequences, and an associated promoter sequence are useful in methods of controlling male fertility in plants. Recombinant expression cassettes, vectors, plant cells, and plants comprise a disclosed nucleotide sequence and may encode a disclosed amino acid sequence. The recombinant expression cassettes are useful in controlling fertility, especially male fertility of annual crops. The promoter is useful in driving expression of an operably-linked heterologous polynucleotide. Constructs comprising homology to the promoter sequence are useful for downregulation of a polynucleotide associated with the promoter.
