Nitrate, Potassium and Phosphate in Plants
Peter J Lea, Lancaster University, Lancaster, UK
Published online: April 2001
The kinetics of the uptake of nitrate, ammonium, potassium and phosphate by plant roots are described. The uptake mechanisms
are equated to the very recent isolation and characterization of genes encoding specific membrane‐bound transporter proteins.
