Chimeric insecticidal proteins
IRDIG35563 vegetative insecticidal toxins, polynucleotides encoding such toxins, use of such toxins to control pests, and transgenic plants that produce such toxins are disclosed. The invention includes IRDIG35563 variants, fragments and analogs.
1. A recombinant nucleic acid construct comprising one or more heterologous regulatory elements that drive expression of a nucleic acid sequence encoding a polypeptide having insecticidal activity and having at least 96% sequence identity to the polypeptide sequence of SEQ ID NO: 2, and one or more heterologous regulatory elements that drive expression of a nucleic acid sequence encoding either a further polypeptide having insecticidal activity or a polypeptide that confers resistance to an herbicide.
2. The construct of claim 1 in which the nucleic acid sequence encoding the polypeptide having at least 96% sequence identity to the polypeptide sequence of SEQ ID NO: 2 is chosen from the group consisting of SEQ ID NO:1, SEQ ID NO:3, and SEQ ID NO:4.
3. A plant or plant part comprising a nucleic acid construct of claim 1 .
4. A plant or plant part comprising a nucleic acid construct of claim 2 .
5. The plant part of claim 3 wherein the plant part is a seed.
6. The plant part of claim 4 wherein the plant part is a seed.
7. The plant or plant part of claim 3 , wherein the nucleic acid construct encodes a chimeric toxin having insecticidal activity against one or more insects selected from Spodoptera exigua (Beet armyworm, BAW), Spodoptera eridania (Southern armyworm, SAW), Spodoptera frupperda (Fall armyworm, FAW), resistant Spodoptera frupperda (Fall armyworm, FAW), Helicoverpa zea (Corn earworm, CEW), Pseudoplusia includens (Soybean looper, SBL), Anticarsia gemmatalis (Velvetbean caterpillar, VBC), Heliothis virescens (Tobacco budworm, TBW), and Hehcoverpa armigera (Cotton bollworm, CBW).
8. A plant or plant part of claim 4 wherein the nucleic acid construct encodes a chimeric toxin having insecticidal activity against one or more insects selected from Spodoptera exigua (Beet armyworm, BAW), Spodoptera eridania (Southern armyworm, SAW), Spodoptera frupperda (Fall armyworm, FAW), resistant Spodoptera frupperda (rFall armyworm, rFAW), Helicoverpa zea (Corn earworm, CEW), Pseudoplusia includens (Soybean looper, SBL), Anticarsia gemmatalis (Velvetbean caterpillar, VBC), Heliothis virescens (Tobacco budworm, TBW), and Hehcoverpa armigera (Cotton bollworm, CBW).
9. A method for producing an insect resistant or insect tolerant plant comprising breeding a non-transgenic plant with a transgenic plant comprising a construct of claim 1 stably incorporated into the genome of the plant and selecting progeny containing the DNA construct of claim 1 .
