Osmotic adjustment and energy limitations to plant growth in saline soil

Munns, Rana; Passioura, John; Colmer, Timothy D; Byrt, Caitlin

Description

Plant roots must exclude almost all of the Na+ and Cl– in saline soil while taking up water, otherwise these ions would build up to high concentrations in leaves. Plants evaporate c. 50 times more water than they retain, so 98% exclusion would result in shoot NaCl concentrations equal to that of the external medium. Taking up just 2% of the NaCl allows a plant to osmotically adjust the Na+ and Cl– in vacuoles, while organic solutes provide the balancing osmotic pressure in the cytoplasm....[Show more]
