Photosynthesis research: a model to bridge fundamental science, translational products, and socio-economic considerations in agriculture.

abstract：:Transgenic Arabidopsis plants overexpressing the wheat vacuolar Na(+)/H(+) antiporter TNHX1 and H(+)-PPase TVP1 are much more resistant to high concentrations of NaCl and to water deprivation than the wild-type strains. These transgenic plants grow well in the presence of 200 mM NaCl and also under a water-deprivation...
