| Abstract: | The trehalose-6-phosphate synthase gene (TPS) from Saccharomyces cerevisiae Hansen and the drought-responsive promoter from Arabidopsis thaliana (L.) Heynh. have been cloned by PCR procedure. A plant expression vector with TPS under control of Prd29A has been constructed and used for the genetic transformation of tobacco. The transgenic tobacco with Prd29A/TSP demonstrated TPS expression with increased drought tolerance under drought stress. Some obvious morphological changes including dwarf and fine shoot, lancet-shaped leaves and vigorous auxiliary buds have been observed in a few transformed plants. |
