Genetically determined adaptations in roots to nutritional stress: correlation of structure and funcMany plant species are able to adapt to problem soil conditions such as salt toxicity and nutrient deficiencies by modifying transport systems in their roots. This is frequently correlated with anatomical and ultrastructural developments. The role of such developments is discussed in two specific cases: soil salinity and iron deficiency.

The mechanism which enables glycophytes to exclude Na. ions is probably a coupling between K. uptake and Na. extrusion; this is indirect and a proton motive force (p. m. f.) generated by an electrogenic proton pump is thought to power this exchange..
