ABSTRACT:
A plant expression vector is constructed to cause the expression of an amino-terminal portion of the Bacillus thuringiensis delta-endotoxin gene in plant cells and the vector is used to create transgenic plants expressing the toxin. A truncated form of the toxin is used, with carboxy-terminal prolines added for stability. A translational enhancer sequence derived from the untranslated leader sequence from the mRNA of the coat protein gene of alfalfa mosaic virus coat protein gene is placed between a promoter and the toxin gene to increase translational efficiency. The transgenic plants produced are toxic to Lepidopteran pests and can transmit that trait to their progeny by normal Mendelian inheritance.
