摘要: A new polymerase chain reaction-restriction fragment length polymorphism method for the identification of cry8-type genes from Bacillus thuringiensis has been established by designing a pair of new universal primers. By this method, a novel gene, cry8Ga1, encoding a polypeptide of 1,157 amino acids with a deduced molecular mass of 131.2 kDa was identified and cloned from B. thuringiensis HBF-18. Recombinant B. thuringiensis strain HD8G, harboring cry8Ga1, has insecticidal activity against larvae of Melolonthidae pests: Holotrichia oblita and Holotrichia parallela. This is the first report of a Cry toxin that has insecticidal activity to Melolonthidae pest H. oblita.
