Enhancing Salt Tolerance of Plants with Rice OsNHAD Gene

摘要

The present invention pertains to the field of rice genetic engineering. Specifically, the present invention relates to a rice OsNHAD gene that enhances tolerance to salt stress, which was obtained through gene isolation, cloning and function verification, and also to use of the gene in genetic improvement of salt tolerance of rice. Said gene is selected from one of the following nucleotide sequences: 1) the nucleotide sequence from positions 60 to 1649 of SEQ NO: 1 in the Sequence Listing; or 2) a nucleotide sequence that encodes the same protein as that encoded by 1). Transgenic rice plants obtained by introducing into rice the nucleotide sequence comprising OsNHAD gene operably ligated with exogenous promoter had enhanced salt tolerance.
