Gene Details:

• MSU gene ID: LOC_Os06g43220
• RAPdb gene ID: Os06g0639200
• Gene Symbol: OsSAE1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• OsSAE1 knockout lines exhibited delayed seed germination, enhanced sensitivity to abscisic acid (ABA) during germination and in early seedling growth, and reduced seedling salt tolerance.
• OsSAE1 overexpression lines exhibited the converse phenotype, with increased seed germination and salt tolerance.
• In vivo and in vitro assays indicated that OsSAE1 binds directly to the promoter of OsABI5, a major downstream component of the ABA signaling pathway and acts as a major regulator of seed germination and stress response.
• This study provides important insights into OsSAE1 regulation of seed vigor and salt tolerance and facilitates the practical use of OsSAE1 in breeding salt-tolerant varieties suitable for direct seeding cultivation.
• Genetic analyses revealed that OsABI5-mediated ABA signaling functions downstream of OsSAE1.
