| Abstract: | Farnesyl diphosphate synthase is a key enzyme in isoprenoid biosynthesis. The 5' regulatory region of HbFPS from Hevea brasiliensis was cloned using GenomeWalker strategy. TATA box, CAAT box and other core configurations were found in this promoter region. Several sequences similar to eukaryotic cis-regulatory element were found in the 5'-UTR proximal 5' flanking sequence of HbFPS. A plant expression vector with 5' regulatory region of HbFPS from Hevea brasiliensis was constructed and transgenic tobacco plants were obtained by Agrobacterium-mediated transformation. GUS activity analysis revealed that the fragment of 5' regulatory region of HbFPS drived expression of the GUS gene transgenic tobacco plants. |
