    摘要: Disclosed claimed are toxins produced by novel Bacillus thuringiensis isolates designated B.t. PS92J, B.t. PS196S1, B.t. PS201L1, and B.t. PS201T6, which have dipteran and/or corn rootworm activity. Thus, the isolates, or mutants therof, can be used to control such pests. Further, claimed are novel genes encoding these &dgr;-endotoxins, which can be expressed in other hosts. Expression of the &dgr;-endotoxins in such hosts results in the control of susceptible insect pests in the environment of such hosts.

    摘要: The subject invention concerns materials and methods useful in the control of pests and, particularly, plant pests. More specifically, the subject invention provides plant-optimized, polynucleotide sequences that encode pesticidal toxins (full-lengthand truncated). Truncated polynucleotide sequences can be used to produce truncated toxins or for the production of fusion (or chimeric) genes and proteins. The polynucleotide sequences of the subject invention have certain modifications, compared to wild-type sequences, that make them particularly well-suited for optimized expression in plants. Using techniques known to those skilled in the art, the polynucleotide sequences described herein can be used to transform plants in order to confer pest resistance upon the plants.
