Gene Details:

• MSU gene ID: LOC_Os06g14030
• RAPdb gene ID: Os06g0250600
• Gene Symbol: OsGORK OsK5.2
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• OsGORK was expressed to some degree in most tissues, such as leaf blade, node, leaf sheath and root, but at high levels in flowers.
• Differential gene expression of two outward-rectifying shaker-like potassium channels OsSKOR and OsGORK in rice.
• A dual role for the OsK5.2 ion channel in stomatal movements and K+ loading into xylem sap.
• This trait was conferred by at least three complementary mechanisms: (1) its superior ability to activate H+-ATPase pump operation, both at transcriptional and functional levels; (2) reduced sensitivity of K+ efflux channels to reactive oxygen species; and (3) smaller upregulation in OsGORK and higher upregulation of OsAKT1 in tolerant cultivars in response to salt stress.
• The outward shaker channel OsK5.2 improves plant salt tolerance by contributing to control of both leaf transpiration and K(+) secretion into xylem sap.
