-OsHKT2; 4 features expressed in Xenopus oocytes were then analyzed. Even in the case of very low external K + concentration is not detected OsHKT2; Ca2 + permeability capacity of 4, specific performance under high Ca2 + conditions OsHKT2; zero flow potential 4, and OsHKT2; 4 a zero flow potential and conductance lack of sensitivity to external Ca2 +. Before detected OsHKT2; 4 for Ca2 + permeability may be due to activation of Xenopus oocytes induced conductance source. Compared with Na +, OsHKT2; 4 K + permeability exhibits a high capacity (K +> Rb + ≈ Cs +> Na + ≈ Li + ≈ NH4 +). By detecting OsHKT2; 4 external pH sensitive current found in most physiological ionic conditions OsHKT2; 4 does not significantly penetrate H +. Medium further contains Na + and K + in the analysis showed that the low Na + in the external conditions, OsHKT2; 4 K + selective transporter proteins play function, but (> 10mM) are transported under high Na + Na +. These data indicate OsHKT2; 4 is K +, Na + permeability HKT transporter subfamily a new type of function. In addition, OsHKT2; 4 high K + permeability of the system to support the hypothesis that transporters involved in plant K +.
+The family of plant membrane transporters named HKT (for high-affinity K+ transporters) can be subdivided into subfamilies 1 and 2, which, respectively, comprise Na+-selective transporters and transporters able to function as Na+-K+ symporters, at least when expressed in yeast (Saccharomyces cerevisiae) or Xenopus oocytes. Surprisingly, a subfamily 2 member from rice (Oryza sativa), OsHKT2;4, has been proposed to form cation/K+ channels or transporters permeable to Ca2+ when expressed in Xenopus oocytes. Here, OsHKT2;4 functional properties were reassessed in Xenopus oocytes. A Ca2+ permeability through OsHKT2;4 was not detected, even at very low external K+ concentration, as shown by highly negative OsHKT2;4 zero-current potential in high Ca2+ conditions and lack of sensitivity of OsHKT2;4 zero-current potential and conductance to external Ca2+. The Ca2+ permeability previously attributed to OsHKT2;4 probably resulted from activation of an endogenous oocyte conductance. OsHKT2;4 displayed a high permeability to K+ compared with that to Na+ (permeability sequence: K+ > Rb+ ≈ Cs+ > Na+ ≈ Li+ ≈ NH4+). Examination of OsHKT2;4 current sensitivity to external pH suggested that H+ is not significantly permeant through OsHKT2;4 in most physiological ionic conditions. Further analyses in media containing both Na+ and K+ indicated that OsHKT2;4 functions as K+-selective transporter at low external Na+, but transports also Na+ at high (>10 mm) Na+ concentrations. These data identify OsHKT2;4 as a new functional type in the K+ and Na+-permeable HKT transporter subfamily. Furthermore, the high permeability to K+ in OsHKT2;4 supports the hypothesis that this system is dedicated to K+ transport in the plant.
