Gene Details:

• MSU gene ID: None
• RAPdb gene ID: None
• Gene Symbol: OsHKT2 2
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Differential sodium and potassium transport selectivities of the rice OsHKT2;1 and OsHKT2;2 transporters in plant cells.
• Therefore, here we analyze two highly homologous rice (Oryza sativa) HKT transporters in plant cells, OsHKT2;1 and OsHKT2;2, that show differential K(+) permeabilities in heterologous systems.
• Our results suggest that No-OsHKT2;2/1 can contribute to Nona Bokra salt tolerance by enabling root K(+) uptake under saline conditions.
• Our study, however, also identified a new HKT isoform, No-OsHKT2;2/1 in Nona Bokra, a highly salt-tolerant cultivar.
• Its 5’ region corresponds to that of OsHKT2;2, whose full-length sequence is not present in Nipponbare but has been identified in Pokkali, a salt-tolerant rice cultivar.
• No-OsHKT2;2/1 is essentially expressed in roots and displays a significant level of expression at high Na(+) concentrations, in contrast to OsHKT2;1.
