摘要:
Two new Bacillus thuringiensis strains, which are deposited at the DSM under accession nos. 5131 and 5132, produce crystal proteins during sporulation that are toxic to Coleoptera. The crystal proteins contain 74 kDa and 129 kDa protoxins, respectively, which can yield 68 and 66 kDa toxins, respectively, as trypsin-digestion products. A plant, the genome of which is transformed with a DNA sequence that comes from either one of the strains and that codes for its respective toxin, is resistant to Coleoptera. Each strain, itself, or its crystals, crystal proteins, protoxin or toxin can be used as the active ingredient in an insecticidal composition for combatting Coleoptera.
摘要:
A plant cell transformed with all or part of a Bacillus thuringiensis gene coding for either a 130 or 132 kDa protoxin against Lepidoptera, preferably with a part of the gene coding just for the respective 62 or 60 kDa trypsin-digestion product of the protoxin. A plant, regenerated from the transformed cell, is resistant to Lepidoptera.

Four novel Bacillus thuringiensis strains, which are deposited at the BCCM-LMG under accession nos. LMG P-12592, LMG P-12593, LMG P-12594, and LMG P-13493, produce new crystal proteins during sporulation that are toxic to Lepidoptera, more particularly against Noctuidae such as Spodoptera spp. and Agrotis ipsilon, against Pyralidae such as Ostrinta nubilalis, and against Yponomeutidae such as Plutella xylostella, and that are encoded by a novel gene. The crystal proteins contain protoxins, which can yield a toxin as trypsin-digestion product. A plant, the genome of which is transformed with a DNA sequence that comes from either one of the strains and that encodes its respective toxin, is resistant to Lepidoptera. Each strain, itself, or its crystals, crystal proteins, protoxin or toxin can be used as the active ingredient in an insecticidal composition for combatting Lepidoptera.

Two new Bacillus thuringiensis strains, which are deposited at the DSM under accession numbers 5870 and 5871, produce new crystal proteins during sporulation that are toxic to Coleoptera and that are encoded by new genes. The crystal proteins contain protoxins, which can yield toxins as trypsin-digestion products. A plant, the genome of which is transformed with a DNA sequence that comes from either one of the strains and encodes an insecticidally effective portion of its respective protoxin or encodes its respective toxin, is resistant to Coleoptera. Each strain, itself, or its crystals, crystal proteins, protoxin, toxin and/or insecticidally effective protoxin portion can be used as the active ingredient in an insecticidal composition for combatting Coleoptera.

摘要:
The present invention relates to transformed plants and plant cells comprising DNA molecules encoding Bacillus thuringiensis proteins with insecticidal activity. The invention relates more particularly to transformed plants and plant cells comprising DNA molecules encoding the protease resistant toxins BTS02618Aa or BTS02618Ab, as well as to methods of rendering plants or plant cells resistant to insects using these DNA molecules.
