A 150 kDa plasma membrane complex of AtNRT2.5 and AtNAR2.1 is the major contributor to constitutive high-affinity nitrate influx in Arabidopsis thaliana.


In plants that have been deprived of nitrate for a significant length of time, a constitutive high-affinity nitrate transport system (cHATS) is responsible for initial nitrate uptake. This absorbed nitrate leads to the induction of the major nitrate transporters and enzymes involved in nitrate assimilation. By use of (13) NO3 (-) influx measurements and… (More)
