  • Patent number: 9556453
    Abstract: The subject invention relates in part to stacking Cry1Be toxins along with Cry1Fa toxins to prevent insects from developing resistance towards either toxin by itself. As discussed in more detail herein, the subject pair of proteins is a particularly advantageous combination, as no other pair of proteins is known to provide high levels of control and non-cross-resistant activity against both Spodoptera frugiperda (FAW) and Ostrinia nubilalis (ECB) insects. This dual, non-cross-resistant activity is also advantageous because it can reduce the number of proteins/genes needed to target these insects with multiple, non-cross-resistant proteins. This can reduce or eliminate the need for refuge acreage. Accordingly, the subject invention also relates generally to using four genes to provide three proteins for non-cross-resistant control of a first insect, and three proteins for non-cross-resistant control of a second insect. In preferred embodiments, the targeted insects are FAW and ECB.

  • Patent number: 9163225
    Abstract: The invention is drawn to a method for purifying membrane-bound proteins expressed in recombinant insect cells using N-laurosarcosine. The invention is particularly suited for expressing cadherin-type receptors cloned from Ostrinia nubilalis, European Corn Borer, and expressed in Sf9 insect cells. The method is optionally adapted for use with 6-his tag proteins.

  • Publication number: 20150264940
    Abstract: 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.
