Gene Details:

• Gene ID:
• Gene Symbol: SbSOS1
• Gene Name: salt overly sensitive 1
• Genome:
• Species: Salicornia brachiata

Functional Descriptions:

• The SbSOS1 gene from the extreme halophyte Salicornia brachiata enhances Na+loading in xylem and confers salt tolerance in transgenic tobacco.
• The SbSOS1 gene is 3774 bp long and encodes a protein of 1159 amino acids. SbSOS1 exhibited a greater level of constitutive expression in roots than in shoots and was further increased by salt stress.
• Overexpressing the S. brachiata SbSOS1 gene in tobacco conferred high salt tolerance, promoted seed germination and increased root length, shoot length, leaf area, fresh weight, dry weight, relative water content (RWC), chlorophyll, K+/Na+ ratio, membrane stability index, soluble sugar, proline and amino acid content relative to wild type (WT) plants.
• Transgenic lines also showed increased K+ and Ca2+ content in root tissue compared to WT, which reflect that SbSOS1 indirectly affects the other transporters activity.
• In addition to Na+ efflux outside the plasma membrane, SbSOS1 also helps to maintain variable Na+ content in different organs and also affect the other transporters activity indirectly.
