This book utilizes a unique approach to plant pathology by combining the results from studies on the anatomy and physiology of diseased plants to show the mutual links among pathological changes in plants, particularly the effect of changes in cells and tissues. These changes in turn affect the structure and function of the diseased plant and are considered a pathosystem in plant cells, tissues, and organs. Information in the book is categorized by cytopathological and histopathological changes; organopathological and morphological changes are included within these larger categories. Symptoms related to changes in diseased plant cells, tissues, and organs are discussed, as well as symptoms related to the physiology of diseased cells. This book makes an ideal reference source for students in agriculture, botany, forestry, plant anatomy, plant physiology, and related fields. Plant pathologists, agricultural consultants, agriculturalists, agronomists, horticulturalists, and landscape designers will also find plenty of important information in this one-of-a-kind book.
