• 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

• OsHKT2;1~OsHKT1, OsHKT2;2, HKT2;2/1, a K+-permeable transporter identified in a salt-tolerant rice cultivar through surveys of natural genetic polymorphism, 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
• OsHKT2;1~OsHKT1, OsHKT2;2, HKT2;2/1, a K+-permeable transporter identified in a salt-tolerant rice cultivar through surveys of natural genetic polymorphism, Expressed in Xenopus oocytes or in Saccharomyces cerevisiae, No-OsHKT2;2/1 exhibited a strong permeability to Na(+) and K(+), even at high external Na(+) concentrations, like OsHKT2;2, and in contrast to OsHKT2;1
• OsHKT2;1~OsHKT1, OsHKT2;2, 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
• OsHKT2;1~OsHKT1, OsHKT2;2, Differential sodium and potassium transport selectivities of the rice OsHKT2;1 and OsHKT2;2 transporters in plant cells, Differential sodium and potassium transport selectivities of the rice OsHKT2;1 and OsHKT2;2 transporters in plant cells
