P54144 · AMT11_ARATH

Function

function

High affinity ammonium transporter probably involved in ammonium uptake from the soil, long-distance transport to the shoots and re-uptake of apoplastic ammonium that derives from photorespiration in shoots. Contributes with AMT1-3 to the overall ammonium uptake capacity in roots under nitrogen-deficiency conditions.
