Hordeum vulgare Na+/H+ antiporter HvNHX gene, method for improving salt tolerance in plants by expressing HvNHX gene and transgenic plants with improved salt tolerance developed by the application of the method

摘要

The present invention which is to serve to isolate the sodium ions in the cytoplasm of the plant cell to enhance the salt tolerance vacuoles barley (Hordeumvulgare) sodium-ion / proton-derived reverse transporter (Na + / H + antiporter) (HvNHX1) cDNA sequences, recombinant vectors, transformed with the recombinant vector yeast and plants, salt tolerance of plants by using the gene containing the gene promote the method, the method of enhancing salt tolerance the plant and its seeds using, and to a composition for enhancing salt tolerance of the plant containing the gene. ; The process according to the invention showed a large and can be grown to high salt acquaintances reclaimed land by using the gene and the gene to isolate a vacuolar the sodium ions of the plant in the cytoplasm increase the salt tolerance of the cell and the plant object usefulness as agronomic environmentally chemical it also is an advantage that the manufacture and development of a superior plant, may be useful bulriji production conditions or the like plant seed, and increase the utilization efficiency of industries. ; Barley, sodium ion / proton reverse carriers, HvNHX1, mutation, rice, salt resistance, yeast, transgenic plants
