Abstract
The present invention relates to polypeptides, and polynucleotides encoding therefor, with cation transporter activity. In particular, the present invention relates to methods for producing, identifying, and/or breeding transgenic or non-transgenic plants, especially wheat or barley plants, with enhanced tolerance to saline and/or sodic soils, and/or reduced sodium accumulation in an aerial part of the plant. Also provided are plants produced using these methods.

- 77. A method of identifying a wheat or barley plant with enhanced tolerance to saline and/or sodic soils, and/or having a phenotype of reduced sodium accumulation in an aerial part of the plant, the method comprising detecting a nucleic acid molecule of the plant, wherein the nucleic acid molecule is linked to, and/or comprises at least a part of, a Nax2 locus in the plant that comprises an allele that confers enhanced tolerance to saline and/or sodic soils, and/or that confers reduced sodium accumulation in an aerial part of the plant.
