Welcome to AMT1 !

Ammonium transporters (AMTs) are plasma membrane proteins that exclusively transport ammonium/ammonia. These proteins are encoded by an ancient gene family with many members. The first identified ammonium transporter gene family, AMT1 was composed of high-affinity NH+4 transporters in Arabidopsis. Plants need more nitrogen (N) than any other mineral nutrients for their growth. They use different soil nitrogen sources including inorganic (ammonium [NH+4] and nitrate [NO?3]) and organic complexes (amino acids) and compounds. The ammonium transporter (AMT) is responsible for transporting ammonium/ammonia from extracellular into intracellular locations. In plant, once ammonium is uptaken into root cells by AMTs, it is ultimately directed into glutamine via glutamine synthase (GS).
