Mitochondria in Higher Plants

Mitochondria in Higher Plants: Structure, Function, and Biogenesis is a collection and interpretation of information on plant mitochondria. It explains not only the basic enzymology of ATP synthesis coupled to electron transport that seems to constitute the major activity of the mitochondria, but also many other aspects that make plant mitochondria rather more diverse than their animal counterparts.
Organized into five chapters, this book begins with the morphological and cytological observations on mitochondria, and proceeding through membrane and matrix functions to participation in metabolism and biogenesis. Each section presents the unique properties of plant mitochondria within the framework of general mitochondrial structure and function.
This book is intended not only for research workers and students interested in the enzymology of plant mitochondria respiration, but also for graduate and undergraduate students in the field of plant biochemistry, cell physiology, and molecular biology. It will be useful as a starting point for those students wishing to pursue special studies in this field.
