Expression of Soybean Proteinase Inhibitor in Sweetpotato

Transformation of sweetpotato (Ipomoea batatas) with serine-type proteinase inhibitors (Pls) offer a new strategy for developing host resistance against sweetpotato weevil (Cyclas spp.), the major threat to sweetpotato worldwide. This paper describes the Agrobacterium-mediated transformation of sweetpotato with a soybean kunitz trypsin inhibitor (SKTI-4) cDNA clone and the analysis of recombinant SBTI produced in sweetpotato cells against trypsin and sweetpotato leaf proteinases.
