AimsNitrogen, especially NH4+, can stimulate the uptake of phosphorus in plants, but the underlying mechanisms have not been clearly elucidated. Because phosphate is taken up via an anion/H+ co-transport process, we propose that the stimulated uptake of phosphorus by NH4+ versus NO3- nutrition may be related to the activity of plasma membrane H+ ATPase. In the present study, we investigated the effect of NH4+ and NO3- on phosphorus uptake and plasma membrane H+ ATPase activity in rice… CONTINUE READING
