Gene ID Name Evidence / Role Function (this paper)
Mp8g05280 MpAMT1.4 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.
Mp8g05300 MpAMT1.5 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.
