GM peppers that are tolerant to the oriental tobacco budworm

다국어 초록 (Multilingual Abstract)

Bt gene derived from the B. thuringiensis has been used for developing GM crops and those crops are already on the market. The aim of this study is to construct a genetic transformation with peppers using CryIAc1 gene and consequently to develop GM peppers resistant to the oriental tobacco budworm. We have developed transgenic peppers using Agrobacterium-mediated transformation, and obtained 5 T0 peppers. T0 peppers were self-crossed and T1 pepper fruits were exposed to larvae to test the survival rate. The survival rate of larvae that were fed with GM fruits decreased dramatically while with non-GM fruits the rate was not changed much. In order to establish the selection and the culturing of bug through a year, an incubating system for tobacco budworm in chamber was manufactured and a selection system under the media that are mixed with GM green pepper was obtained. Using those system, T3 peppers tolerant to tobacco budworm were selected.
