  • Patent number: 7838293
    Abstract: The present invention discloses the isolation, cloning and use of insecticidal crystal proteins from Bacillus thuringiensis. The present invention isolates a novel insecticidal crystal protein gene cry7Ba1 from B. thuringiensis subsp. huazhongensis YBT-978 strain, and said gene encodes a novel insecticidal crystal protein Cry7Ba1, which shows insecticidal activity against Lepidopteran insects. The present invention also discloses the gene sequence of the novel insecticidal crystal protein, uses suitable expression vectors to transform micro-organisms so as to express the product Cry7Ba1 encoded by the gene and make it exert the insecticidal activity of the protein against Lepidopteran pests.

  • Publication number: 20070207463
    Abstract: A method for enriching the GC base pair content of a DNA molecule the method comprising the steps of (a) providing a DNA template molecule in which at least some of the A residues are base paired with U residues and (b) replicating the DNA template molecule provided in step (a) under conditions in the replication reaction medium in which at least some of the U residues base pair with a G residue. Typically, the DNA template molecule in (a) is produced by replicating a first template DNA molecule in the presence of dUTP so that at least some of the T residues of the first template are replaced by U residues to form a second template molecule.
