ANTIPORTER GENE FROM PORTERESIA COARCTATA FOR CONFERRING STRESS TOLERANCE

摘要

The present invention relates to isolation and characterization of a cDNA corresponding to Na+/H+ antiporter gene from Porteresia coarctata, the deduced protein of the said gene and its promoter region capable of conferring tolerance to abiotic stress in plants. The present invention also relates to cloning the complete cDNA sequence corresponding to Na+/H+ antiporter gene from Porteresia coarctata. The present invention also relates to isolating the promoter for Na+/H+ antiporter gene from Porteresia coarctata. The invention further provides a method for producing abiotic stress tolerant transgenic plants. Further, the invention relates to salt tolerant transformed plants of rice over-expressing the Na+/H+ antiporter gene from Porteresia coarctata.
