Gene ID Name Evidence / Role Function (this paper)
MpAMT1;4 missing experimental subject Expressed in Xenopus oocytes and assayed by two-electrode voltage clamp; perfusion of NH4Cl produced large inward currents (RNA injected at 30-fold lower concentration to reduce activity), demonstrating electrogenic ammonium transport. Supports the conclusion that land plant AMTs are electrogenic.
MpAMT1;5 missing experimental subject Expressed in Xenopus oocytes and assayed by two-electrode voltage clamp; 50 uM NH4Cl produced large inward currents, demonstrating electrogenic ammonium transport. One of the Marchantia AMTs supporting electrogenicity of land plant AMT proteins.
