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 All of the Chapters are reviews and most include hitherto unpublished data or theoretical treatments.

Plasmodesmata are minuscule plasma corridors between plant cells which are of paramount importance for transport, communication and signalling between cells. These nano-channels are responsible for the integrated action of cells within tissues and for the subdivision of the plant body into working symplast units. This book updates the wealth of new information in this rapidly expanding field. Reputed workers in the field discuss major techniques in plasmodesmatal research and describe recent discoveries on the ultrastructure, the functioning and the role of plasmodesmata in intracellular transport and communication, in cell differentiation, plant development and virus translocation.

Plants offer exciting opportunities to understand major biological questions, i.e. the regulation of development and morphogenesis. How are changes of the environment, developmental cues, and other signals perceived and transduced in physiological responses? What are the elements of plant signalling pathways and what is their organization? The panoply of molecular tools and techniques as well as the blossoming field of plant genetics are providing an exciting ground for major breakthroughs in unravelling the fundamental mechanisms of plant signalling. The present book establishes a state-of-the-art framework spanning the wide spectrum of perception, signal transduction events and transport processes, including cell proliferation and cell cycle regulation, embryogenesis, and flowering. Moreover, the volume emphasizes the role of the major plant signalling substances known to date (the phytohormones and more recently studied substances) and summarizes what we know on their molecular mechanisms of action. The book emphasizes how the use of molecular technology has made plant signalling processes accessible to experimental test.

Intracellular junctions provide routes for direct cell-to-cell signalling in both plants and animals. The present volume treats the parallels and differences between such junctions in animals and plants and discusses the most recent methods of examining the physiological functions and regulation of intracellular communication. Strong evidence of both molecular as well as functional simi§ larities between plasmodesmata and gap junctions is increasing. Even more interesting is the discovery that animal gap junction proteins cross-react immunologically with some proteins in plant cells. Thus the molecular construction and function of these crucially important ultrastructural cell components is now open to a concerted research effort to understand how cells, both plant and animal, facilitate and regulate intercellular transport.

Annual Plant Reviews, Volume 16 Intercellular communication in plants plays a vital role in the co-ordination of processes leading to the formation of a functional organism. The signalling systems must function at a local level to co-ordinate events of cellular differentiation, over long distances to co-ordinate developmental and physiological responses in different parts of the plant, and they must even operate between separate individuals - for example, to control fertilization as part of the evolutionary strategy of a particular species. To cope with the diverse requirements for intercellular signalling, plants have evolved a spectrum of molecular mechanisms, and significant progress has been made over the last few years in our understanding of these processes. This volume provides an overview of our current understanding of intercellular communication in plants, with an emphasis on those research areas showing significant recent progress and promise. It is directed at researchers and professionals in plant biochemistry, physiology, cell biology and molecular biology.

The plant cell wall plays a vital role in almost every aspect of plant physiology. New techniques in spectroscopy, biophysics and molecular biology have revealed the extraordinary complexity of its molecular architecture and just how important this structure is in the control of plant growth and development. The Second Edition of this accessible and integrated textbook has been revised and updated throughout. As well as focusing on the structure and function of plant cell walls the book also looks at the applications of this research. It discusses how plant cell walls can be exploited by the biotechnology industry and some of the main challenges for future research. Key topics include: architecture and skeletal functions of the wall; cell-wall formation; control of cell growth; role in intracellular transport; interactions with other organisms; cell-wall degradation; biotechnological applications of cell-walls; role in diet and health. This textbook provides a clear, well illustrated introduction to the physiology and biochemistry of plant cell walls which will be invaluable to upper level undergraduate and post graduate students of plant physiology, plant pathology, plant biotechnology and biochemistry.

Since their discovery over 100 years ago, plasmodesmata have been the focus of intense investigation. Plasmodesmata are unique to plants and form an intercellular continuum for the transport of solutes, signals and ribonucleoprotein complexes. It is now clear that plasmodesmata formation and regulation are central to a diverse range of plant functions that include developmental programming, host-pathogen interactions and systemic RNA signaling. This book provides a state-of-the-art overview of the diverse forms and functions of plasmodesmata. It covers the structure and evolution of plasmodesmata, their role in plant development and solute transport, and their central function in systemic signaling via the phloem. It includes critical evaluations of current methods used to study intercellular transport via plasmodesmata. The volume is directed at researchers and professionals in plant cell biology, plant molecular biology, plant physiology and plant pathology.

A state-of-the-art overview of the intricate functional virus/host relationships that allow a virus or viroid to move cell-to-cell and systemically through the plant, as well as from plant to plant, and, thus, to spread infection. The book also illustrates the mechanisms by which viruses overcome plant defence responses, such as RNA silencing. Arabidopsis is used as an illustration of a plant host eminently suitable for genetic approaches to identify novel players in plant/virus interactions.

Plasmodesmata (PD) are plant-specific intercellular nanopores defined by specialised domains of the plasma membrane (PM) and the endoplasmic reticulum (ER), both of which contain unique proteins, and probably different lipid compositions than the surrounding bulk membranes. The PD membranes form concentric tubules with a minimal outer diameter of only 50 nm, and the central ER strand constricted to ~10-15 nm, representing one of the narrowest stable membrane tubules in nature. This unique membrane architecture poses many biophysical, structural and functional questions. PM continuity across PD raises the question as to how a locally confined membrane site is established and maintained at PD. There is increasing evidence that the PM within PD may be enriched in membrane ‘rafts’ or TET web domains. Lipid rafts often function as signalling platforms, in line with the emerging view of PD as central players in plant defense responses. Lipid-lipid immiscibility could also provide a mechanism for membrane sub- compartmentalisation at PD. Intricate connections of the PM to the wall and the underlying cytoskeleton and ER may anchor the specialised domains locally. The ER within PD is even more strongly modified. Its extreme curvature suggests that it is stabilised by densely packed proteins, potentially members of the reticulon family that tubulate the cortical ER. The diameter of the constricted ER within PD is similar to membrane stalks in dynamin-mediated membrane fission during endocytosis and may need to be stabilised against spontaneous rupture. The function of this extreme membrane constriction, and the reasons why the ER is connected between plant cells remain unknown. Whilst the technically challenging search for the protein components of PD is ongoing, there has been significant recent progress in research on biological membranes that could benefit our understanding of PD function. With this Research Topic, we therefore aim to bring together researchers in the PD field and those in related areas, such as membrane biophysics, membrane composition and fluidity, protein-lipid interactions, lateral membrane heterogeneity, lipid rafts, membrane curvature, and membrane fusion/fission. We wish to address questions such as: - What mechanisms restrict lateral mobility of proteins and lipids along the PD membranes? - How can specific proteins be targeted to and turned over from membrane domains with restricted lateral access? - What elements (lipids, proteins, membrane curvature, packing order, thickness etc.) may contribute to the identity of PD membranes? - How do the structural and functional features of PD compare to other ER-PM contact sites? - How is the high curvature of the PD ER stabilised and what are possible functions of such a tightly constricted membrane tubule? - Do PD need to be prevented from spontaneous collapse and sealing? - What technologies are available to address these questions that can underpin PD research? We welcome interested individuals to contribute their expertise and develop new hypotheses on the particular biological and biophysical questions posed by PD. We are particularly looking for articles (Original Research Articles, Technical Advances and State-of-the-Art reviews) that would expand on or challenge current perceptions of PD and stimulate discussion.

The ability of plants to exchange RNA molecules and transcription factors between cells and tissues is a relatively recent discovery. However, all areas of research such as plant development, metabolism, and plant pathogen interactions now realize the importance of this phenomenon. In this book, experts from the field of intercellular transport deal with various aspects on intercellular transport of viruses and plant endogenous macromolecules such as transcription factors, small silencing-induced and micro RNAs, and other RNAs and their function as signals. The aim of the book is to provide the basic information on the cell-to-cell transport mechanism and to give an overview of the current knowledge of this relatively new field of research. To quote the words of W.J. Lucas “...pioneering discoveries in this field of cell-to-cell and long-distance signaling should certainly entice talented young scholars to join this frontier area of plant biology” . He is certainly right as we got only a first glimpse on the cellular factors regulating intercellular transport and the functional diversity of the ever-increasing number of proteins and RNA molecules found to move between cells.
