Abstract: Abstract: The Arabidopsis thaliana AtNHX1 gene encodes a vacuolar Na⁺/H⁺antiporter that is important in plant salt-tolerance. In this paper, the basic structure, function and mechanism of AtNHX1 were summarized, and it was expected to act as an effective salt-tolerance gene in plant engineering. The other family members of Arabidopsis thaliana vacuolar Na⁺/H⁺ antiporters are also discussed here.
Key words: Na⁺/H⁺ antiporter; vacuole; ion compartmentation; plant salt-tolerance
