High-Affinity NH₄⁺ transport in rice (Oryza sativa L.) : physiology, biochemistry and molecular biology
In plants, NH₄⁺ influx occurs via a saturable high-affinity, and a low-affinity transport system. Regulation of ¹³NH₄⁺ influx was studied by altering NH₄⁺ supply and pretreatments with amino acids. Diurnal variations in NH₄⁺ influx were also studied. Increased N pools caused NH₄⁺ influx to decrea...
