A high-affinity potassium transporter (MeHKT1) from cassava (Manihot esculenta) negatively regulates the response of transgenic Arabidopsis to salt stress.

Background: High-affinity potassium transporters (HKTs) are crucial in facilitating potassium uptake by plants. Many types of HKTs confer salt tolerance to plants through regulating K and Na homeostasis under salinity stress. However, their specific functions in cassava (Manihot esculenta) remain unclear.

Positive Regulatory Roles of HAK5 under K Deficiency or High Salt Stress.

HAK/KUP/KT family members have been identified as playing key roles in K uptake and salt tolerance in numerous higher plants. However, their functions in cassava ( Cantz) remain unknown. In this study, a gene encoding for a high-affinity potassium transporter () was isolated from cassava and its function was investigated.

[Distribution of Rh blood group in 51 283 cases of inpatients and voluntary blood donors].

Objective To investigate the distribution characteristics of Rh blood group in 51 283 cases of inpatients and voluntary blood donors. Methods Micro-column gel test was used to detect RhD, RhE, Rhe, RhC, Rhc antigen in 31 818 cases of hospitalized patients and 19 465 cases of voluntary blood donors. Results There were significant differences in Rh blood type distribution between inpatients and voluntary blood donors.
