Aims to provide a clear and manageable introduction to the important aspects of solute transport in plants in a way that is accessible to advanced undergraduates and immediate postgraduates. The authors consider the elements of transport at various levels of organization within the plant: intracellular and intercellular, as well as at the level of the whole plant. The book describes what is known of the mechanisms by which solutes cross membrane barriers into and within plant cells, together with the physical principles involved. Specific chapters cover the question of whether movement occurs in the apoplast or symplast, long-distance transport in phloem and xylem, and ion uptake by roots. The book is written for plant physiologists and biochemists, plant biologists and those studying plant breeding and agriculture.
