Plant Peroxisomes deals with the biogenesis of plant peroxisomes and its relevance to the proposed model for peroxisome biogenesis in germinated seeds. The book is divided into seven chapters that discuss the history, cytochemistry, morphology, properties, isolation, metabolism, enzymology, and ontogeny of plant peroxisomes. The book first explains how advances in electron microscopy and cell fractionation studies have led to the detection of peroxisome. The subsequent chapters discuss the types and metabolic functions of plant peroxisomes and the cytochemical procedures for establishing the localization of specific enzymes and for analyzing peroxisome distribution in nonflowering plants, algae, and fungi. A chapter presents methods of peroxisome isolation from various tissues and the physical and chemical properties of the isolated organelles. Considerable chapters are devoted to the metabolic functions, enzymatic activities, development of their form, and biochemistry of peroxisomes. Several key enzymes of the glycolate pathway of photorespiration found in leaf peroxisomes are presented. A discussion on the physiology of plant peroxisomes is provided. This book will be of value to professional scientists and graduate students concerned with plant metabolism and development.DIFFERENTIAL EXPRESSION OF ISOZYMES A.
