Gene Details:

• Gene ID: Zm00001eb033240
• Gene Symbol: ZmSOS1 nhx7
• Gene Name: Na+/H+ antiporter 7
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• First, we showed that a naturally occurring 4-bp frame-shifting deletion in ZmSOS1 caused the salt hypersensitive phenotype of the maize inbred line LH65.
• Accordingly, mutants lacking ZmSOS1 also displayed a salt hypersensitive phenotype, due to an impaired root-to-rhizosphere Na+ efflux and an increased shoot Na+ concentration.
• The maize SOS pathway confers a conservative salt-tolerant role, and the components of SOS pathway (ZmSOS1 and ZmCBL8) confer the natural variations of Na+ regulation and salt tolerance in maize, therefore providing important gene targets for breeding salt-tolerant maize.
• Demonstrated that the functional variations of the SOS pathway components (ZmSOS1 and ZmCBL8) conferred the diversities of Na+ regulation and salt tolerance in maize.
• ZmSOS1 is crucial for Na+ regulation and salt tolerance in maize.
