Cellular And Subcellular Localization In Plant Metabolism

Morphological differences between cells and the exis tence of morphologically distinct particles have been examined since cells were first recognized. Each techno logical advance in detection and visualization has led to the description of different organelles and cell types. Basic biochemical processes in cells were recognized and are now weIl understood. It is only recently however, that research has expanded to include the specific meta bolic function of the specialized cell types and organelles. In some cases metabolic roles were recognized when the organelles were first described, e.g., chloroplasts, mito chondria, etc., in others the metabolic role remains unknown. Chemical and biochemical specialization in plants or their organelles is equally challenging. Although biochemists have laboured intensivelyon many isolated plant organelles, it is only recently that technical advances have permitted the examination of specialization in the metabolism of cell types. This area of research, although under intensive investigation in some areas of plant metabolism, is still in its infancy. Further developments in methodology or in production of specific genetic lines of plants will greatly improve our understanding of the specialization of different tissues and cell types. This volume describes the current status in the dis cipline as presented in a Symposium on the Cellular and Subcellular Specialization in Plant Metabolism during the Annual Meeting of the Phytochemical Society of North America, at Cornell University, Ithaca, N.Y., on August 10-14, 1981.

The Biochemistry of Plants: A Comprehensive Treatise, Volume 11: Biochemistry of Metabolism provides information pertinent to the chemical and biochemical aspects of metabolism. This book discusses the control mechanisms of metabolism. Organized into nine chapters, this volume begins with an overview of the history of biochemistry and discusses the developments in the kinetics of regulatory enzymes. This text then examines a theory that explains how subunit interactions modulate the rate of conversion of a substrate into a product. Other chapters consider some relation between cell-wall elongation and cell-wall charge density and explore the subcellular localization of the enzymes of glycolysis. This book discusses as well the regulation of glycolysis and the pentose phosphate pathway. The final chapter deals with the pathways of C1 metabolism that are of prime importance, as the synthesis of several cellular constituents depends directly or indirectly on folate metabolism. This book is a valuable resource for plant biochemists, neurobiochemists, molecular biologists, senior graduate students, and research workers.

In the two decades since the last comprehensive work on plant peroxisomes appeared, the scientific approaches employed in the study of plant biology have changed beyond all recognition. The accelerating pace of plant research in the post-genomic era is leading us to appreciate that peroxisomes have many important roles in plant cells, including reserve mobilisation, nitrogen assimilation, defence against stress, and metabolism of plant hormones, which are vital for productivity and normal plant development. Many plant scientists are finding, and will no doubt continue to find, that their own area of research is connected in some way to peroxisomes. Written by the leading experts in the field, this book surveys peroxisomal metabolic pathways, protein targeting and biogenesis of the organelle and prospects for the manipulation of peroxisomal function for biotechnological purposes. It aims to draw together the current state of the art as a convenient starting point for anyone, student or researcher, who wishes to know about plant peroxisomes.
