    Abstract: Agrobacterium strains that harbor transformation-enhancing genes on a plasmid capable of replication independently of the Agrobacterium chromosome, the Ti plasmid, and plant transformation binary vectors, and uses for these Agrobacterium strains are provided. Additionally, Agrobacterium strains that are deficient in DNA recombination functions that result in instability or rearrangement of plant transformation binary vectors, and that harbor transformation-enhancing genes on a plasmid capable of replication independently of the Agrobacterium chromosome, the Ti plasmid, and plant transformation binary vectors, and uses for these strains, are also provided. Further included are Agrobacterium strains that harbor transformation-enhancing genes integrated into the Agrobacterium chromosome at a locus that does not interfere with or otherwise compromise the normal growth and plant transformation ability of the Agrobacterium cells, and uses for these Agrobacterium strains.

  • 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.
