Annual Plant Reviews, Volume 15 This volume addresses some of the most important and hotly-pursued topics in the field of plant membrane transport. The first two chapters consider membrane transport analysis, emphasizing concepts, techniques and tools for electrophysiology. Chapters 3-8 divide along boundaries of pumps, coupled transporters and channels; the addition of a chapter on water channels highlights this rapidly expanding and, until recently, highly controversial topic. Chapters 9 and 10 deal with issues of Ca2+ and H+ signalling, and of membrane traffic that increasingly attracts the attention of researchers in plant development. Finally, chapters 11 and 12 take a post-gemic look at the problems of understanding the integration of transport mechanisms and its relevance to irganic nutrition and phytoremediation. An overriding theme throughout is the extent to which the research on membrane transport w informs the fields of plant cell biology and physiology, and is itself enriched in return. This is a volume for researchers and professionals in plant biochemistry, physiology and molecular biology.
