＜正＞ Although many data indicate that high-affinity potassium transporters （HKT）, inward rectifying potassium channels （AKT） and low-affinity cation transporters （LCT） mediate Na+ influx into plant cells, evidence is now accumulating that suggests non-selective cation channels （NSCCs） are the major pathway for Na+ influx into root cells. As can be inferred from the range of suggestions, the mechanism of plant Na+ uptake remains largely unknown. The data on which current hypotheses rest has largely come from experiments on glycophytes （including the model plant Arabidopsis）, which accumulate little Na+ into their leaves when compared with most
