Genbank accession number

• Our analyses of subcellular localizations and expression patterns showed that OsHAK21 was localized in the plasma membrane, and expressed in xylem parenchyma and individual endodermal cells (putative passage cells)
• Here, we report a significant inducement of OsHAK21 expression by high salinity treatment, and provide genetic evidence of the involvement of OsHAK21 in rice salt tolerance
• The potassium transporter OsHAK21 functions in the maintenance of ion homeostasis and tolerance to salt stress in rice.
• Disruption of OsHAK21 rendered plants sensitive to salt stress
• These results demonstrate that OsHAK21 may mediate K(+) absorption by the plasma membrane, and play crucial roles in the maintenance of the Na(+) /K(+) homeostasis in rice under salt stress
• Further functional characterizations of OsHAK21 in K(+) uptake-deficient yeast and Arabidopsis revealed that OsHAK21 possesses K(+) transporter activity
