[Method] First, the prokaryotic expression plasmid ScMYB：：pEASY-E1 was constructed; and then the effects of various induction conditions on its expression were studied, in- cluding concentration of inductor IPTG, induction time, induction temperature and OD600 of the bacteria solution. [Result] All the induction time, induction temperature, and OD600 except the concentration of IPTG have significant influence on the expres- sion of target protein. [Conclusion] The expression of target protein reaches the high- est level under the conditions of induction temperature 37 ℃, induction time 4 h and OD600 0.6-1.0.展开更多
