Eight invited papers review the major recent developments in the study of the movement of photoassimilates within the higher plants. The major events of the entire migration from the chloroplast of the photosynthetic cell to the sink organ are covered. The chapters discuss transport within photosynthetic cells and between leaf cells; the structure of phloem; the origin, destination, and fate of phloem solutes; the loading and unloading of photoassimilates, the physiological aspects of translation, and the relationship and regulation between source and sink organs. Includes an appendix of tables showing the physico-chemical aspects of phloem sap. Intended for postgraduate and advanced undergraduate students.

This textbook is second edition of popular textbook of plant physiology and metabolism. The first edition of this book gained noteworthy acceptance (more than 4.9 Million downloads) among graduate and masters level students and faculty world over, with many Universities recommending it as a preferred reading in their syllabi. The second edition provides up to date and latest information on all the topics covered while also including the basic concepts. The text is supported with clear, easy to understand Figures, Tables, Box items, summaries, perspectives, thought-provoking multiple-choice questions, latest references for further reading, glossary and a detailed subject index. Authors have also added a number of key concepts, discoveries in the form of boxed- items in each chapter. Plant physiology deals with understanding the various processes, functioning, growth, development and survival of plants in normal and stressful conditions. The study involves analysis of the above-stated processes at molecular, sub-cellular, cellular, tissue and plant level in relation with its surrounding environment. Plant physiology is an experimental science, and its concepts are very rapidly changing through applications from chemical biology, cytochemical, fluorometric, biochemical and molecular techniques, and metabolomic and proteomic analysis. Consequently, this branch of modern plant biology has experienced significant generation of new information in most areas. The newer concepts so derived are being also rapidly put into applications in crop physiology. Novel molecules, such nanourea, nitric oxide, gaseous signalling molecules like hydrogen sulphide, are rapidly finding significant applications among crop plants. This textbook, therefore, brings forth an inclusive coverage of the field contained in 35 chapters, divided into five major units. It serves as essential reading material for post-graduate and undergraduate students of botany, plant sciences, plant physiology, agriculture, forestry, ecology, soil science, and environmental sciences. This textbook is also of interest to teachers, researchers, scientists, and policymakers.

Adopting an interdisciplinary approach to the study of photoassimilate partitioning and source-sink relationhips, this work details the major aspects of source-sink physiology and metabolism, the integration of individual components and photoassimilate partitioning, and the whole plant source-sink relationships in 16 agriculturally important crops. The work examines in detail the components of carbon partitioning, such as ecology, photosynthesis, loading, transport and anatomy, and discusses the impact of genetic, environmental and agrotechnical factors on the parts of whole plant source-link physiology.

Vascular Transport in Plants provides an up-to-date synthesis of new research on the biology of long distance transport processes in plants. It is a valuable resource and reference for researchers and graduate level students in physiology, molecular biology, physiology, ecology, ecological physiology, development, and all applied disciplines related to agriculture, horticulture, forestry and biotechnology. The book considers long-distance transport from the perspective of molecular level processes to whole plant function, allowing readers to integrate information relating to vascular transport across multiple scales. The book is unique in presenting xylem and phloem transport processes in plants together in a comparative style that emphasizes the important interactions between these two parallel transport systems. - Includes 105 exceptional figures - Discusses xylem and phloem transport in a single volume, highlighting their interactions - Syntheses of structure, function and biology of vascular transport by leading authorities - Poses unsolved questions and stimulates future research - Provides a new conceptual framework for vascular function in plants

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.

Plant hormones play a crucial role in controlling the way in which plants growand develop. Whilemetabolism providesthepowerand buildingblocks for plant life, it is the hormones that regulate the speed of growth of the individual parts and integrate these parts to produce the form that we recognize as a plant. In addition, theyplayacontrolling role inthe processes of reproduction. This book is a description ofthese natural chemicals: how they are synthesizedand metabolized; howthey work; whatwe knowoftheir molecular biology; how we measure them; and a description ofsome ofthe roles they play in regulating plant growth and development. Emphasis has also been placed on the new findings on plant hormones deriving from the expanding use ofmolecular biology as a tool to understand these fascinating regulatory molecules. Even at the present time, when the role of genes in regulating all aspects of growth and development is considered of prime importance, it is still clear that the path of development is nonetheless very much under hormonal control, either via changes in hormone levels in response to changes in gene transcription, or with the hormones themselves as regulators ofgene transcription. This is not a conference proceedings, but a selected collection ofnewly written, integrated, illustrated reviews describing our knowledge of plant hormones, and the experimental work that is the foundation of this knowledge.
