Metabolic aspects of the transport of ions by cells and tissues of roots

  • Brian C. Loughman
Part of the Developments in Plant and Soil Sciences book series (DPSS, volume 4)


There is no clear cut viewpoint concerning the mechanism of transport of solutes into and within roots that is applicable to all plants and all solutes. Most attention has been given to ionised species, particularly those that are not incorporated into organic molecules, e.g. K+, Na+, Ca+ + and Cl. Ions that are rapidly metabolised such as NO 3 , SO 4 − − and H2PO 4 give rise to special problems as do uncharged solutes such as sugars that become charged during entry by phosphorylation.
