Nitrate (NO3-) can accumulate in high concentrations in plant cell vacuoles if it is not reduced, reutilized or transported into the cytoplasm. Such accumulation of NO3- in the vacuole occurs when mechanisms for NO3- assimilation in the cytoplasm are saturated. Moreover, other processes such as efflux across the plasma membrane might affect NO3- accumulation in the vacuole. These are the main reasons limiting nitrogen use efficiency (NUE) in plants. This study elucidates mechanisms for NO3- transport from the cytoplasm to vacuoles by the V-proton pump (V-ATPase and V-PPase) and their relations...
