| Outline of Final Research Achievements |
Our study indicated that Cry toxins use widely ABC transporters as receptors and ABC transporters have thousands times higher facilitating activity than Cadherin for Cry toxins pore formation. This confirmed possibility and reality of our concept that we could freely design and modify activity of insecticidal protein from BT if we can develop a method for Cry toxin to maturate fitting property to ABC transporters. In addition, this made the status where we can create several attractive evolution models to beat the realistic problems. In addition, as outline of Cry toxin's binding site to ABC transporter was indicated, basic strategy for the construction of Cry toxin library became easier to be planned.
