COMPOSITIONS AND METHODS FOR DETERRING FEEDING BY PSYLLIDS

The invention relates to a plant that includes a transgene encoding a heterologous polypeptide conferring on plant expressing said polypeptide resistance to a hemipteroid sap-sucking insect. The transgene is also expressed in a plant component (such as a leaf). Typically, expression of such polypeptides deters feeding by insects such as psyllids (such as an Asian citrus psyllid, the African citrus psyllid, or the American citrus psyllid). Exemplary plants useful in the invention are citrus or solanaceous plants.

Cry1D for controlling corn earworm

The subject invention relates in part to the surprising discovery that Cry1Da is active against corn earworm (CEW), Helicoverpa zea (Boddie). Methods for using Cry1Da in transgenic plants to prevent serious crop damage is described. Leaf and silk bioassays using transgenic maize expressing full length, core toxin region or chimeric Cry1Da demonstrated good insect protection against CEW larvae damage.

Polynucleotide and method used for controlling insect invasion

An isolated polynucleotide includes: (a) a polynucleotide sequence as shown in SEQ ID NO: 1; or (b) a polynucleotide sequence having at least 15, 17, 19 or 21 contiguous nucleotides of SEQ ID NO: 1, wherein the growth of a pest of the order Coleoptera is inhibited when the pest of the order Coleoptera ingests double-stranded RNA comprising at least one strand that is complementary to the described polynucleotide sequence; or (c) any polynucleotide sequence as shown in SEQ ID NO: 3 to SEQ ID NO: 6; or (d) a polynucleotide sequence which hybridizes under stringent conditions with the polynucleotide sequence as defined in (a), (b) or (c). A plurality of target sequences are used for controlling a target gene c4506 of Monolepta hieroglyphica, which is a pest of the order Coleoptera.

Engineered pesticidal proteins and methods of controlling plant pests

The invention provides nucleic acids, polypeptides, transgenic plants, compositions and methods for conferring pesticidal activity (e.g., insecticidal activity) to bacteria, plants, plant cells, tissues and seeds. Nucleic acids encoding the insecticidal proteins can be used to transform prokaryotic and eukaryotic organisms, including plants, to express the insecticidal proteins. The recombinant organisms and compositions containing the recombinant organisms or insecticidal proteins can be used to control a pest (e.g., an insect).

INSECTICIDAL PROTEINS FROM PLANTS AND METHODS FOR THEIR USE

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.

Targeted mosquitocidal toxins

Insecticidal toxins described herein are fused toxin peptides made up of a targeting domain fused to a toxin domain. The targeting peptide generates a specific association with mosquitoes by causing the fused toxin peptide to bind mosquitoes in a way that leads to the insecticidal activity. Transgenic plants described herein are mosquitocidal by expressing an insecticidal toxin protein in nectar that includes a targeting peptide to ensure specificity against mosquitoes. These transgenic plants serve as role models for safety, since they are non-crop plants and specific to one mosquito species.

Insect-resistant herbicide-tolerant corn transformation event

An insect-resistant herbicide-tolerant corn transformation event, and a related creation method, a detection method, and application thereof are provided herein. Using the corn inbred line Xiang 249 as a receptor, by means of agrobacterium-mediated genetic transformation, obtaining a corn plant with an exogenous gene insert inserted at a specific genomic locus, the exogenous gene insert comprising the following three genes: an insect-resistant gene, a glufosinate resistant gene, and a glyphosate resistant gene. In the obtained transformation event, the inserted exogenous genes are positioned at a non-functional locus of the corn genome, and do not affect the expression of the other genes of the receptor plant, such that the transgenic corn plant maintains good agronomic traits whilst acquiring insect resistance and herbicide tolerance.
