Production and identification of salt-tolerant transgenic rice plants

To relieve the damage of salt to the cell, many plants accumulated some low-molecular weight organic compounds, which were called osmoprotectant, such as betaine, mannitol, and sorbitol. Therefore if the gene-encoding enzyme responsible for synthesizing the osmoprotectant was transformed into rice plants, the salt-tolerance capacity of the transgenic plants would be increased, and the enormous loss caused by salinization of soil would be reduced.
