ammonium transport

Ammonium transport is necessary to transport : AMMONIUM ammonium from the soil into the root plasma. They play a role in making available : AMMONIUM ammonium for several metabolic processes, like the conversion of glycine to serine in the photorespiratory nitrogen cycle, deamination of pheylalanine, and degradation of amino acids. The protonated form of : AMMONIUM ammonium is the one that is available from the soil. It is common in the cytosol, mitochondria, vacoules and in the phloem and xylem of plants. Physiological studies have shown that there are two types of ammonium transporters, HAT and LAT i.e high and low affinity transporters in plants . The expression of these transporters in shoots and roots indicate that they could be involved in intracellular transport within the plant in addition to transporting : AMMONIUM ammonium from the soil across the root plasma membrane . These are transmembrane proteins belonging to ammonium transporter/methylamine permease/rhesus (AMT/MEP/Rh) protein family, present in all organisms .
