Abstract: Geranyl diphosphate synthase(GPPS)gene total ORF(1 131 bp)was amplified with specific primers and linked to expression vector pET-28a. Verified by double restriction enzyme digestion and sequencing, recombined vector pET-28a-GPPS was transferred to Rosetta(DE3)and the recombined protein was overexpressed after 6 h induced by 1 mmol/L IPTG. Using RNA interference method to research gene function is matured gradually. In our research, the expression vector pBI121-RNAi-GPPS targeting to GPPS gene was structured successfully.
