[The structure and regulation of plant proteinase inhibitor genes and their strategy in pest control].
The diverse plant proteinase inhibitors (PIs) genes from different plant species have been isolated and their products with one or more genes are targeted at different biochemical and physiological process with the insect, and well played a potent defensive role against insects and pathogens. The use of recombinant PIs and synergistic activation to protect plants has been incorporated in integrated pest management program. Though they may not replace the use of chemical pesticides in the near future, but effectively complement it. Currently, the role and mechanism of action for most of these inhibitors are being studied in detail. This article describes the structure of PIs genes, their regulation and expression, and discusses the strategy to develop transgenic plants against phytophagous insects.
