The subject invention concerns materials and methods useful in the control ofpests and, particularly, plant pests. More specifically, thesubject invention provides plant-optimized, polynucleotide sequences thatencode pesticidal toxins (full-length and truncated). Truncatedpolynucleotide sequences can be used to produce truncated toxins or for theproduction of fusion (or chimeric) genes and proteins.The polynucleotide sequences of the subject invention have certainmodifications, compared to wild-type sequences, that make themparticularly well-suited for optimized expression in plants. Using techniquesknown to those skilled in the art, the polynucleotide sequencesdescribed herein can be used to transfer plants in order to confer pestresistance upon said plants. The subject invention further providesplant-optimized, polynucleotide sequences that encode C-terminal, protoxinportions that can be used with genes encoding truncated, coretoxins to produce full-length toxins. In addition, the subject inventionprovides preferred amino acid sequences that are encoded by theplant-optimized polynucleotide sequences disclosed herein.
