摘要:
The subject invention relates in part to Cry3Aa in combination with Cry6Aa. The subject invention relates in part to the surprising discovery that combinations of Cry3Aa 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. The subject invention also relates in part to combinations of Cry3Aa and Cry6Aa proteins “triple-stacked” or “multi-stacked” with another insecticidal protein(s) such as a Cry6Aa protein or binary Cry34/35 proteins. Thus, such embodiments target rootworms with three modes of action. Transgenic plants, including corn, comprising a cry6Aa gene and a cry3Aa gene are included within the scope of the subject invention.

The subject invention concerns plants protected from nematode feeding damage and improved versions of Cry proteins. Synthetic genes encoding Cry proteins are also part of the subject invention. Another embodiment of the subject invention includes plants transformed with the genes of the subject invention. In yet another embodiment the subject invention concerns Bt proteins for in-plant protection against crop damage by root knot nematode (RKN; Meloidogyne incognita) and soybean cyst nematode (SCN; Heterodera glycines).

The subject invention relates in part to the surprising discovery that combinations of Cry3Aa 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 relates in part to Cry34Ab/35Ab in combination with Cry3Aa. The subject invention relates in part to the surprising discovery that combinations of Cry34Ab/Cry35Ab and Cry3Aa are useful for preventing development of resistance (to either insecticidal protein system alone) by a corn rootworm (Diabrotica spp.) population. As one skilled in the art will recognize with the benefit of this disclosure, corn plants producing these insecticidal Cry proteins will be 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.
摘要:
The subject invention concerns new classes of pesticidally active proteins and the polynucleotide sequences which encode these proteins. More specifically, in preferred embodiments, pesticidal proteins of approximately 40-50 kDa and of approximately 10-15 kDa are used for controlling corn rootworms. Also described are novel pesticidal isolates of Bacillus thuringiensis.

摘要:
The subject invention concerns materials and methods useful in the control of non-mammalian pests and, particularly, plant pests. In a specific embodiment, the subject invention provides new Bacillus thuringiensis toxins useful for the control of lepidopterans. The subject invention further provides nucleotide sequences which encode the toxins of the subject invention. The nucleotide sequences of the subject invention can be used to transform hosts, such as plants, to express the pesticidal toxins of the subject invention. The subject invention further concerns novel nucleotide primers for the identification of genes encoding toxins active against pests. The primers are useful in PCR techniques to produce gene fragments which are characteristic of genes encoding these toxins. The primers are also useful as nucleotide probes to detect the toxin-encoding genes.
摘要:
The subject invention concerns materials and methods useful in the control of pests and, particularly, plant pests. More specifically, the subject invention concerns novel genes and pesticidal toxins referred to as 86A1(b) and 52A1(b). In preferred embodiments, the subject toxins are used for controlling flea beetles of the genus Phyllotreta. Using the genes described herein, the transformation of plants can be accomplished using techniques known to those skilled in the art. In addition, the subject invention provides toxin genes optimized for expression in plants.

摘要:
Novel B.t. genes encoding toxins active against lepidopteran insects have been cloned from a novel lepidopteran-active B. thuringiensis isolate P515862. The DNA encoding the B.t. toxin can be used to transform various hosts to express the B.t. toxin.
