Molecular characterization of ginseng farnesyl diphosphate synthase gene and its up-regulation by methyl jasmonate

We isolated a gene encoding for farnesyl diphosphate synthase (FPS) from Panax ginseng, a species that produces a large quantity of triterpene saponins such as ginsenosides. The deduced amino acid sequence of PgFPS was 77, 84 and 95 % identical to those of Arabidopsis, Hevea, and Centella. Southern...

الملخص:We isolated a gene encoding for farnesyl diphosphate synthase (FPS) from Panax ginseng, a species that produces a large quantity of triterpene saponins such as ginsenosides. The deduced amino acid sequence of PgFPS was 77, 84 and 95 % identical to those of Arabidopsis, Hevea, and Centella. Southern blot analysis indicated that P. ginseng contained more than two genes encoding for FPS. When the cDNA of PgFPS was expressed in Escherichia coli, the recombinant enzyme, purified with a His-tag column, was found to possess FPS activity. When cultures of ginseng hairy root were treated with 0.1 mM methyl jasmonate (MJ), PgFPS mRNA was detected within 12 h of the treatment, and achieved maximum after 24 h. Also FPS activity in the hairy root cultures after 12 h of MJ treatment was higher than that of the control.
