Gene Details:

Functional Descriptions:

  • Two ammonium transporter genes, ZmAMT1|3|ZmAMT2|1a and ZmAMT1|3|ZmAMT2|ZmAMT1|3|ZmAMT2, were isolated from a maize root-specific cDNA library by functional complementation of an ammonium uptake-defective yeast mutant.
  • Ectopic expression of both genes in an ammonium uptake-defective Arabidopsis mutant conferred high-affinity ammonium uptake capacities in roots with substrate affinities of 48 and ZmAMT1|3|ZmAMT2****ZmAMT1|3|ZmAMT2 μM for ZmAMT1|3|ZmAMT2|1a and ZmAMT1|3|ZmAMT2|ZmAMT1|3|ZmAMT2, respectively.
  • The two rhizodermis-localized transporters ZmAMT1|3|ZmAMT2|1a and ZmAMT1|3|ZmAMT2|ZmAMT1|3|ZmAMT2 are most probably the major components in the high-affinity transport system in maize roots. A particular regulatory feature is their persistent induction by ammonium rather than an up-regulation under N deficiency.
  • ZmAMT1|3|ZmAMT2|1a and ZmAMT1|3|ZmAMT2|ZmAMT1|3|ZmAMT2 encode functional ammonium transporters for high-affinity ammonium uptake in maize roots.
