| |
| − | In our project,we built recombinant plasmids and transformed them into brewer yeast to produce dsRNA. Because of the lack of T7 RNA promoter, we transformed a plasmid which contained T7 RNA polymerase gene. And IPTG could induce the expression of T7 RNA polymerase gene.
| |
| − | We tested the IPTG inductive effect in T7 RNA polymerase. In our project,we built the yeast which contained two parts to produce dsRNA. Meanwhile,IPTG could induce the operation of T7 RNA polymerase.Therefore,we could test the concentration of dsRNA to estimate the inductive effect.
| |
| − | After the test of IPTG induction,we firmly believed that we could make use of the best IPTG concentration and induction time lengths to get the minimum cost in agriculture.

This part codes for the T7 RNA polymerase.This part does not pose any biological threat.
