Summarizing research progress achieved in 32 areas of cell biology covered in this series, this volume places special emphasis on the following topics: recognition in parasitic and symbiotic systems - the molecular biology and genetics of susceptibility and resistance of plants and animals to pathogens, parasites and symbionts - the cell to cell recognition and differentiation - the most challenging problems in developmental biology of plants and animals - the plasticity in cell to cell communication which plays a major role in cell differentiation and function.

This book is based on practical experience and is therefore written as a prac tical manual. The fore-runners of the book were the manuals of the first and second EMBO-Courses on "Micromethods in Molecular Biology" which were held in G6ttingen in the spring of 1970 and the autumn of 1971. This book may serve as a manual not only for the participants of the third EMBO-Course to be held in G6ttingen in autumn 1973, but also for all experimenters who are interested in using micromethods. It must be emphasized from the outset that this book is conceived as a "cook book" and not as a monograph...
