Tóm tắt: In this study, we investigated the expression of recombinant miraculin in tobacco (Nicotiana tabacum) hairy roots. To increase miraculin expression, the heat shock protein 18.2 promoter and terminator were used to drive the expression of miraculin gene in a potential host system. Synthetic miraculin gene was transformed into Nicotiana tobacum leaf explants via Agrohaclerium rhizogenes. The transgenic hairy root clones that conlained synthetic miraculin gene showed rapid growth and reached maximum growth atter 35-day culture. When the expression of miraculin gene was regulated by heat shock protein 18.2 promoter and heat shock protein terminator, the expression of recombinant miraculin increased than the control regulated by CaMV 35S promoter and nopaline synthase terminator. The recombinant miraculin was 19.97 ng per µg of the total soluble protein and equivalently with approximately 2% of the total sohible protein. For the first time, a taste modifying miraculin was successtully expressed in tobacco hairy root. The results in this study have given a promising approach for the applieation of the transgenic hairy root system to produce recombinant miraculin.
