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.
A transgenic plant comprising a first heterologous polynucleotide encoding a Pteridophyta insecticidal polypeptide (PtIP) active against a Lepidopteran pest and a second heterologous polynucleotide encoding a bacterial insecticidal polypeptide active against the Lepidopteran pest, wherein the first heterologous polynucleotide and the second heterologous polynucleotide are operably linked to one or more promoter sequences, the PtIP and the bacterial insecticidal polypeptide exhibiting different modes of action against the Lepidopteran pest, wherein said Pteridophyta insecticidal polypeptide comprises an amino acid sequence having at least 71% sequence identity to SEQ ID NO:
A DNA construct comprising i) a first polynucleotide encoding a Pteridophyta insecticidal polypeptide (PtIP), wherein said polypeptide comprises an amino acid sequence having at least 71% sequence identity to SEQ ID NO:1 and ii) a second polynucleotide encoding a bacterial insecticidal polypeptide, wherein the first polynucleotide and the second heterologous polynucleotides are operably linked to one or more promoter polynucleotide sequences, the PtIP and the bacterial insecticidal polypeptide exhibiting different modes of action against a Lepidopteran pest.
