摘要:
The subject invention relates in part to stacking certain Cry genes along with Cry 1Fa to result in products that are more durable and less prone towards insects developing resistance towards the activity of any of the toxins (such as Cry 1Fa) by itself. Embodiments of the Cry 1F stacking partners include Cry2Aa, Cry 1I, and Cry 1E. These stacks can be used to control FAW and/or ECB as described herein.
摘要:
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.

The subject invention relates in part to Cry34Ab/35Ab in combination with Cry6Aa. The subject invention relates in part to the surprising discovery that combinations of Cry34Ab/Cry35Ab and Cry6Aa are useful for preventing development of resistance (to either insecticidal protein system alone) by a corn rootworm (Diabrotica spp.) population. Included within the subject invention are plants producing these insecticidal Cry proteins, which are useful to mitigate concern that a corn rootworm population could develop that would be resistant to either of these insecticidal protein systems alone. Plants (and acreage planted with such plants) that produce these two insecticidal protein systems are included within the scope of the subject invention. The subject invention also relates in part to combinations of Cry34Ab/35Ab and Cry3Aa proteins "triple stacked" with a Cry6Aa protein. Transgenic plants, including corn, comprising a cry6Aa gene, cry34Ab/35Ab genes, and a cry3Aa gene are included within the scope of the subject invention. Thus, such embodiments target rootworms with three modes of action.
