Ten years ago, at the International Botanical Congress in Edinburgh, a group of us from various countries discussed the difficulty of pursuing academic problems in depth at such meetings. In particular, we were discouraged at the poverty of time for phloem transport. From long association, we were conscious of the extraordinary breadth of the problem, from developmental through anatomical, to biophysical and physiological. Only by a reasonable understanding of all these components could one hope to come to some kind of understanding. We decided to establish common plant material so that data would have a common source. Similarly, we resolved to exchange information by circulating pre-publication manuscripts. For awhile, after the meeting was a pleasant memory, the plan seemed to be working; but, as is so often the case, human infirmities and foibles played early and, subsequently, predominant roles. Some became administrators (a punishment for good behaviour); others concentrated on alternative rings in their academic circuses. The next Congress (in Seattle) proved similar to its predecessor in its neglect and, consequently, succor was sought elsewhere. A little known, but remarkably understanding group becoming visible was the Science Committee and the Division of Scientific Affairs of N. A. T. O. Its sponsorship of Advanced Study Institutes including phytochemistry and phytophysics, was unusual both in the generosity of its funding and in the requirements for academic quality.

When WILHELM RUHLAND developed his plan for an Encyclopedia of Plant Physiol ogy more than three decades ago, biology could still be conveniently subdivided into classical areas. Even within plant physiology, subdivisions were not too difficult to make, and general principles could be covered sufficiently in the two introductory volumes of the Encyclopedia on the physical and chemical basis of cell biology. But the situation changed rapidly even during the 12-year publication period of the Encyclopedia (1955-1967). The new molecular direction of genetics and structural research on biopolymers had an integrating effect on all other biological fields, including plant physiology, and it became increasingly difficult to keep previously distinct areas separated. RUHLAND'S overall plan included 18 volumes and about 22,000 pages. It covered the entire field of plant physiology, in most cases from the very beginning. But, as each volume appeared, it was clear that its content would soon be outdated.

This revision of the now classic Plant Anatomy offers a completely updated review of the structure, function, and development of meristems, cells, and tissues of the plant body. The text follows a logical structure-based organization. Beginning with a general overview, chapters then cover the protoplast, cell wall, and meristems, through to phloem, periderm, and secretory structures. "There are few more iconic texts in botany than Esau’s Plant Anatomy... this 3rd edition is a very worthy successor to previous editions..." ANNALS OF BOTANY, June 2007

he biological sciences are dominated by the idea that cells are the functionally autonomous, physically separated, discrete units of life. TThis concept was propounded in the 19th century by discoveries of the cellular structuring of both plants and animals. Moreover, the ap parent autonomy of unicellular eukaryotes, as well as the cellular basis of the mammalian brain (an organ whose anatomy for a long while defied attempts to validate the idea of the cellular nature of its neurons), seemed to provide the final conclusive evidence for the completeness of *cell theory', a theory which has persisted in an almost dogmatic form up to the present day. However, it is very obvious that there are numerous observations which indicate that it is not the cells which serve as the basic units of biological life but that this property falls to some other, subcellular assemblage. To deal with this intricate problem concerning the fundamental unit of living matter, we proposed the so-called Cell Body concept which, in fact, devel ops an exceedingly original idea proposed by Julius Sachs at the end of the 19th century. In the case of eukaryotic cells, DNA-enriched nuclei are intimately associated with a microtubular cytoskeleton. In this configuration—as a Cell Body—these two items comprise the fundamental functional and struc tural unit of eukaryotic living matter. The Cell Body seems to be inherent to all cells in all organisms.

Cell walls are defining feature of plant life. The unique and multi-faceted role they play in plant growth and development has long been of interest to students and researchers. Plant Cell Wall Patterning and Cell Shape looks at the diverse function of cell walls in plant development, intercellular communication, and defining cell shape. Plant Cell Wall Patterning and Cell Shape is divided into three sections. The first section looks at role cell walls play in defining cell shape. The second section looks more broadly at plant development. While the third and final section looks at new insights into cell wall patterning.

This Volume attempts to summarise and integrate a field of study in its entirety: the nature of plasmodesmata, and the part these inter cellular connections play in the life of the plant. Except in the all embracing early reviews of the pre-electron microscope era, there has been a tendency for the subject to be approached from disparate points of view: plant physiologists, developmental biologists, biophysicists, virologists and cytologists all contributing to the corpus of knowledge, but often without a full appreciation of each others' goals and probl ems, and sometimes misinterpreting each others' findings. In June 1975 a group of about 40 specialists in these various disciplines, all with a common interest in intercellular communication in plants, met for two days, presented papers, talked, argued, and in general pooled their know ledge. Out of a synthesis of manuscripts and discussions there has emerged, by an editorial process of elimination of unnecessary dupli cation and insertions to ensure completeness of coverage, the present book - not so much a straight record of a conference, as a Monograph based on the proceedings. All of the Chapters are reviews and most include hitherto unpublished data or theoretical treatments.
