    • This invention provides plants having resistance to invertebrate pests. More specifically, this invention discloses a non-natural transgenic plant cell expressing at least one invertebrate miRNA in planta for suppression of a target gene of an invertebrate pest or of a symbiont associated with the invertebrate pest. Also provided are recombinant DNA constructs for expression of at least one invertebrate miRNA in planta, a non-natural transgenic plant containing the non-natural transgenic plant cell of this invention, a non-natural transgenic plant grown from the non-natural transgenic plant cell of this invention, and non-natural transgenic seed produced by the non-natural transgenic plants, as well as commodity products produced from a non-natural transgenic plant cell, plant, or seed of this invention. This invention further provides a method of suppressing at least one target gene of an invertebrate pest of a plant or of a symbiont associated with the invertebrate, including providing a plant including the non-natural transgenic plant cell of this invention, wherein the invertebrate is the invertebrate pest, the recombinant DNA is transcribed in the non-natural transgenic plant cell to the recombinant miRNA precursor, and when the invertebrate pest ingests the recombinant miRNA precursor, the at least one target gene is suppressed.

    • The present invention provides isolated polynucleotide sequences encoding ET37, TIC810 and TIC812 proteins from Bacillus thuringiensis, and nucleotide sequences for use in expressing TIC809, ET37, TIC810 and TIC812, and fusions of various insecticidally effective combinations of these proteins such as TIC 127, in plants. Methods of making and using the polynucleotide sequences and the proteins in the development of transgenic plant cells and transgenic plants exhibiting improved insect resistance against (1) Coleopteran insects including Western Corn Rootworm (Dibrotica virgifera), Southern Corn Rootworm (Dibrotica undecempunctata), Northern Corn Rootworm (Diabrotica barbed), Mexican Corn Rootworm (Diabrotica virgifera zeae), Brazilian Corn Rootworm (Diabrotica balteata) and Brazilian Corn Rootworm complex (Diabrotica viridula and Diabrotica speciosa), and against Hemipteran insects such as Lygus bugs, are disclosed.
    • 本发明提供编码来自苏云金芽孢杆菌的ET37,TIC810和TIC812蛋白质的分离的多核苷酸序列,以及用于表达TIC809,ET37,TIC810和TIC812的核苷酸序列,以及这些蛋白质如TIC 127在植物中的各种杀虫有效组合的融合 。 在转基因植物细胞和转基因植物的开发中制备和使用多核苷酸序列和蛋白质的方法和转基因植物对(1)鞘翅目昆虫包括西方玉米根虫(Dibrotica virgifera),南方玉米根虫(Dibrotica undecempunctata),北方玉米 披露了根虫(Diabrotica barbed),墨西哥玉米根虫(Diabrotica virgifera zeae),巴西玉米根虫(Diabrotica balteata)和巴西玉米Rootworm综合体(Diabrotica viridula和Diabrotica speciosa),以及针对半翅目昆虫如Lygus虫。
