Genbank accession number

• 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.

• OsGORK~OsK5.2, OsNAC2~OsTIL1~OMTN2~OsORE1, OsNAC2 positively affects salt-induced cell death and binds to the OsAP37 and OsCOX11 promoters., Furthermore, K+-efflux channels (OsGORK and OsSKOR) were obviously activated by OsNAC2
• OsAKT1, OsGORK~OsK5.2, Tissue-Specific Regulation of Na+ and K+ Transporters Explains Genotypic Differences in Salinity Stress Tolerance in Rice., 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
