Gene Details:

• MSU gene ID: LOC_Os08g07010
• RAPdb gene ID: Os08g0167000
• Gene Symbol: OsABCG18
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• OsABCG18 encodes a plasma membrane protein and is primarily expressed in the vascular tissues of the root, stem and leaf midribs.
• While the mutation reduced the root-derived cytokinins in the shoot and grain yield, overexpression of OsABCG18 significantly increased cytokinins in the shoot and improved grain yield.
• The findings for OsABCG18 as a transporter for long-distance transport of cytokinin provide new insights into the cytokinin transport mechanism and a novel strategy to increase cytokinins in the shoot and promote grain yield.
• ABC Transporter OsABCG18 Controls the Shootward Transport of Cytokinins and Grain Yield in Rice.
• The cytokinin profiling, 14C-tZ tracer and xylem-sap assays demonstrated that the shootward transport of the root-derived cytokinins was significantly suppressed in the OsABCG18 mutants.
