Gene Details:

• MSU gene ID: LOC_Os01g01430
• RAPdb gene ID: Os01g0104200
• Gene Symbol: OsNAC016
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Further investigation revealed that OsNAC016 regulated the expression of the brassinosteroid biosynthesis gene D2 by binding to its promoter.
• Moreover, OsNAC016 interacted with and was phosphorylated by GSK3/SHAGGY-LIKE KINASE2 (GSK2), a negative regulator in the BR pathway.
• OsNAC016 regulates plant architecture and drought tolerance by interacting with the kinases GSK2 and SAPK8.
• Meanwhile, the mutant OsNAC016 had improved drought stress tolerance, supported by a decreased water loss rate and enhanced stomatal closure in response to exogenous ABA, but OsNAC016-overexpressing plants showed attenuated drought tolerance and reduced ABA sensitivity.
• Our findings establish that OsNAC016 is positively involved in BR-regulated rice architecture, negatively modulates ABA-mediated drought tolerance, and is regulated by GSK2, SAPK8, and OsPUB43 through post-translational modification.
• Further, OSMOTIC STRESS/ABA-ACTIVATED PROTEIN KINASE8 (SAPK8) phosphorylated OsNAC016 and reduced its stability.
• The loss-of-function mutant OsNAC016 exhibited erect leaves and shortened internodes, but OsNAC016-overexpressing plants had opposite phenotypes.
