Gene Details:

• Gene ID: Zm00001eb033240
• Gene Symbol: ZmSTL2 nhx7 ZmSOS1
• Gene Name: Salt Tolerance Locus 2
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• Identified a salt hypersensitive maize inbred line LH65, and observed that the salt hypersensitive phenotype was conferred by a single recessive gene (Salt Tolerance Locus 2, ZmSTL2).
• ZmSTL2 encodes the Na+/H+ antipoter ZmSOS1, and observed that a naturally occurred 4-bp frame-shifting deletion in the coding region of ZmSOS1 was associated with the impaired Na+ regulation and the salt hypersensitive phenotype of LH65.
• The candidate of ZmSTL2 is the Na+/H+ antipoter gene ZmSOS1.
• The Na+/H+ antipoter gene Zm00001d031232/ZmSOS1 is likely to underly the phenotypic variation conferred by ZmSTL2.
• Observed that ZmSTL2/ZmSOS1 is an important salt-tolerant locus in maize that promotes salt tolerance by mediating root-to-rhizosphere Na+ efflux as well as promoting shoot Na+ exclusion.
