AbstractSince the identification of the first vegetative insecticidal protein (Vip3Aa1), more than sixty Vip3 toxins have been isolated from Bacillus thuringiensis (Bt), increasing the number of potentially useful toxins available for in tegrated pest control programs and resistance management. In this study, three holotypes of a novel vip3 gene were identified from different Bt strains and characterized at the molecular level. These genes were 2412 bp long and encode 90-kDa (803 amino acids) proteins with sequence similarities of less than 70% with the Vip3 toxins identified so far. These constitute a novel class of Vip3 proteins, namely Vip3C. The nucleotide sequences of these Vip3C proteins were 99% similar, and differed only in a few point mutations that rendered non-synonymous substitutions in the predicted amino acid sequences.
