This is the second of the set of three volumes in the Encyclopedia of Plant Physiology, New Series, that will cover the area of the hormonal regulation of plant growth and development. The overall plan for the set assumes that this area of plant physiology is sufficiently mature for a review of current knowl edge to be organized in terms of unifying principles and processes. Reviews in the past have generally treated each class of hormone individually, but this set of volumes is subdivided according to the properties common to all classes. Such an organization permits the examination of the hypothesis that differing classes of hormones, acting according to common principles, are determinants of processes and phases in plant development. Also in keeping with this theme, a plant hormone is defined as a compound with the properties held in common by the native members of the recognized classes of hormone. Current knowledge of the hormonal regulation of plant development is grouped so that the three volumes consider advancing levels of organizational complexity, viz: molecular and subcellular; cells, tissues, organs, and the plant as an organized whole; and the plant in relation to its environment.

This lively book examines recent trends in animal product consumption and diet; reviews industry efforts, policies, and programs aimed at improving the nutritional attributes of animal products; and offers suggestions for further research. In addition, the volume reviews dietary and health recommendations from major health organizations and notes specific target levels for nutrients.

The dynamic role of plant hormones in regulation of plant growth and development revealed by its control of rates of metabolic processes and various related enzymetic reactions at molecular and submolecular levels is now weil established. During the course of last 35 years endless development in agricultural biotechnology has provided immense literature to understand hormone-regulated aspects of plant growth and development ; but plant physiologists all over the world are still devoting themselves and will continue for an indifinite period to disclose the mystries of this regulation. Volume I of this series has already been published and has been accepted weil. This encouraged me to edit aseries of volumes (I do not know the number) on this subject. In the following pages various aspects of hormone-controlled physiological processes Iike, Hormonal Control of pro tein synthesis in plants, Auxin-induced elongation, Hormonal regulation of abnormal growth in plants, Hormonal regulation of development in mosses, Some phenolics as plant growth and morphogenesis regulators, Plant growth regulating properties of sterol inhibiting fungicides, Hormonal regulation of sex expression in plants, Water relation and plant growth regulators, Hormonal regulation of root development under water stress, Gravity perception and responses meehanism in graviresponding cereal grass shoots, Hormonal regulation of leaf Growth senescence in relation to stomatal movement, and Chloroindole auxins of pea and related species, have been included.

The present volume treats the molecular and subcellular aspects of hormones and the processes they regulate. Although it deals with chemically distinct classes of hormone, this volume stresses properties and modes of studying them, that are common to all classes.
