Abstract
- OsNHX1 gene (Na+/H+ antiporter gene of Oryza saliva L.) was introduced into Poplar 84K with Agrobacterium tumefaciens-mediated transformation. PCR, Southern and Northern blot analysis showed that OsNHX1 gene was incorporated successfully into the genome of Poplar 84K and expressed in these transgenic plants. Salt tolerance test showed that three lines of transgenic plants grew normally in the presence of 200 mmol/L NaCl, while the Na+ content in the leaves of the transgenic plants grown at 200 mmol/L NaCl was significantly higher than that in plants grown at 0 mmol/L NaCl. The osmotic potential in the transgenic plants with high salinity treatment was lower than that of control plants. Our results demonstrate the potential use of these transgenic plants for agricultural use in saline soils. [ABSTRACT FROM AUTHOR]
