Encyclopedia of Plant and Crop Science is the first-ever single-source reference work to inclusively cover classic and modern studies in plant biology in conjunction with research, applications, and innovations in crop science and agriculture. From the fundamentals of plant growth and reproduction to developments in agronomy and agricultural science, the encyclopedia's authoritative content nurtures communication between these academically distinct yet intrinsically related fields-offering a spread of clear, descriptive, and concise entries to optimally serve scientists, agriculturalists, policy makers, students, and the general public.

Part 3=Volume 12C.

It is impossible in a single volume to deal comprehensively with all classes of secondary plant compounds. In the earlier series of this Encyclopedia emphasis was laid on the isoprenoids and plant phenols. While these compounds have not been neglected in the present volume we have attempted to achieve a more balanced presentation by drawing attention to the importance of nitrogenous secondary metabolites such as the alkaloids, amines and non-protein amino acids. Most of the compounds or groups of compounds included in Volume 8 are of restricted distribution within the plant kingdom and wherever possible we have provided information concerning their chemistry, biochemistry, taxonomic signifi cance and probable ecological roles. Secondary compounds cannot be defined in terms of restricted distribution, however, nor can they be defined without refer ence to the plants in which they occur, as it is possible that a given compound occurring in two species may have a primary role in one and not in the other. As our knowledge of biochemistry increases we shall no doubt find it necessary to revise our ideas concerning the roles of a great many of the compounds which are found in plants.

An easy-to-use single reference source covering the full range of subject areas associated with plant pathology! This comprehensive volume covers the entire field of plant pathology. It does not merely define the numerous subjects covered (297 topics carefully arranged in 38 sections!) but describes them in detail. Each section of this boo

Plant Physiology and Development incorporates the latest advances in plant biology, making Plant Physiology the most authoritative and widely used upper-division plant biology textbook. Up to date, comprehensive, and meticulously illustrated, the improved integration of developmental material throughout the text ensures that Plant Physiology and Development provides the best educational foundation possible for the next generation of plant biologists. This new, updated edition includes current information to improve understanding while maintaining the core structure of the book. Figures have been revised and simplified wherever possible. To eliminate redundancy, stomatal function (Chapter 10 in the previous edition) has been reassigned to other chapters. In addition, a series of feature boxes related to climate change are also included in this edition. An enhanced ebook with embedded self-assessment, Web Topics and Web Essays and Study Questions is available with this edition.

Plant pathology embraces all aspects of biological and scientific activity which are concerned with understanding the complex phenomena of diseases in plants. Physiological plant pathology represents those specialities within plant pathology which focus on the physiological and biochemical activities of pathogens and on the response of host plant tissues. Today there is an increasing recognition on the part of the scientific agri cultural community that only through a deeper and more fundamental under standing of all the interacting components of the agricultural biota can we expect to improve our capabilities of feeding an expanding world population. It is in this context that physiological plant pathology has assumed new significance within the broader field of plant pathology. No longer are studies on the biochemistry and physiology of pathogens and pathogenesis merely isolated academic exercises; rather, a substantial coherent body of knowledge is accumulating upon which our understanding of the process of disease developmen t and host resistance is being founded. It is from these foundations of knowledge that ultimately new insights into the control of plant diseases may be expected to grow. It seems appropriate, therefore, that at regular intervals those involved in the various subspecialities encompassing the broadest aspects of physiological plant pathology reassess the contributions within the particular specialities in the light of new knowledge and technologies for the purpose of articulating new and productive directions for the future.
