Hormone Action in Plant Development - A Critical Appraisal documents the proceedings of the Tenth Long Ashton Symposium, September 1986. The symposium was convened to assess the evidence for and against the view that plant hormones are endogenous regulators of plant development. The meeting also aimed to focus on and assess promising strategies for future research. The symposium opened with the Douglas Wills Lecture, given by Professor Carl Leopold. In many respects, progress in research on animal hormones seems greater than in the plant sciences and there may well be merit in following progress in animal hormone research as suggested by Professor Leopold. The symposium was comprised of four sessions. The introductory session considered the coordinating role of hormones in plant growth and development, and focused on hormone action at the molecular level, including their binding to receptors and their control of gene expression. The next two sessions embraced contributions on the experimental manipulation of development by genetic (notably by biochemical mutants), chemical (for example, with gibberellin/biosynthesis inhibitors), and environmental (including drought stress) means. All these approaches consolidated the central importance of hormones in plant growth. In the final session, three speakers suggested some promising avenues for future research into the physiology, biochemistry, and molecular biology of plant hormones.

What are plant growth regulators? In the title, and throughout the text, we have adopted this expression to describe a population of endogenous molecules and synthetic compounds of similar structure that are be lieved to play important roles in the regulation of plant differentiation and development. For many years, plant scientists have endeavoured to understand the nature and action of plant growth regulators and, as a result, an awesome quantity of written material now exists describing these chemicals and their effects. In this book we have aimed to distil this wealth of information into a more digestible form, and in particular we have focused our attention on a critical appraisal of the literature. The past few years have witnessed a change of emphasis in plant growth regulator research, which has been fuelled by powerful new techniques in molecular and cell biology. Today we can do more than just apply a plant growth regulator and quantify its effects; we have reached an exciting crossroads where plant scientists, molecular bio logists and chemists can pool their expertise and apply it to the out standing problems in this area. The combination of these three disciplines within the book is clear evidence of this. In keeping with a volume of this size, we have assumed that the reader has a sound knowledge of plant physiology and biochemistry. However, wherever possible, we have highlighted useful reviews which provide background information, along with recent publications that have contributed significantly to the literature.

The Annual Beltsville Symposium provides a forum for interaction among scientists involved in research that is vitally important to agri culture and to the agricultural sciences. The Twelfth Symposium in this series focused on the unifying biochemical and physiological mechan isms controlling growth and development of biological systems - ani mals, plants insects. Unraveling the complex biochemical mechanisms associated with the sequencing of organism growth and development and identifying, locating, and manipulating key control mechanisms are essential in utilizing the full potential of biotechnology for improving the composition and quality of agricultural products and the profitability of agriculture. Accordingly, speakers directed their remarks to basic aspects of biological mechanisms in their area of specialization with considera tion given to current status, future direction, potential impact, and limitations to progress. The Symposium addressed fundamental questions in: -Tissue specific gene regulation: cell division and differentiation -Mechanisms for regulating hormone concentration -Hormonal regulation of growth and development -Non-hormonal regulation of growth and development -Nutritional regulation of growth and development Because the backgrounds of the symposium attendees covered a wide spectrum in the basic biological and physical sciences, each topic was introduced by a brief overview, but general reviews were avoided in favor of findings from on-going research projects. The symposium brought together a distinguished group of invited scientists from around the world who are leaders. Many attendees made poster presentations which increased the exchange of ideas and sti mulated informal discussion.

The plasma membrane forms the living barrier between the cell and its surroundings. For this reason it has a wide range of important functions related to the regulation of the composition of the cell interior and to com munication with the cell exterior. The plasma membrane has therefore attracted a lot of research interest. Until the early 1970's it was only pos sible to study the plasma membrane in situ, its structure e. g. by electron microscopy and its function e. g. by uptake of radioactively labeled com pounds into the intact cell or tissue. The first isolation of plant protoplasts by enzymatic digestion of the cell wall in the early 1970's was an important step forward in that it provided direct access to the outer surface of the plasma membrane. More importantly, T. K. Hodges and R. J. Leonard in 1972 published the description of a method by which a fraction enriched in plasma membranes could be isolated from plant tissues using sucrose gradient centrifugation. As a result, the 1970's saw a leap forward in our understanding of the structurc and function of the plasma membrane. In 1981, S. Widell and C. Larsson published the first of a series of papers in which plasma membrane vesicles of high yield and purity were isolated from a wide range of plant tissues using aqueous polymer two-phase parti tioning.

This publication is based on the plant processes and reaction sites for which reliable knowledge on both their physiology and biochem-istry and the mode of herbicidal action is available. Targets of the agrochemical research, such as enzymes of biosynthetic pathways or herbicide-binding peptides in the photosynthetic membrane, are highlighted. Detailed knowledge about the target sites will allow bio-chemical model systems to evaluate the biological activity of newly synthesized compounds before their conventional screening in the greenhouse. Quantitative structure/activity relationships should be performed more reliably with simple biological species or enzymol-ogy assays, to aid in the rational design of pesticides. This text is highly valuable for plant physiologists, pathologists, and chemists in the agrochemical industry and universities.

Manipulation of Fruiting contains the proceedings of the 47th University of Nottingham Easter School in Agricultural Science, held at Sutton Bonington, England on April 18-22, 1988. The papers explore developments in the manipulation of fruiting and cover topics ranging from intra-plant competition to pollination, fruit set, and light interception and canopy manipulation. Genetic regulation and chemical manipulation of fruiting are also discussed. This monograph is comprised of 26 chapters divided into nine sections. The first section deals with the interactions that occur between vegetative and reproductive growth, focusing on source-sink effects and dry matter partitioning. The following three sections examine the sequential stages of producing a fruit from flower initiation, dormancy, and anthesis, through pollination to fruit set. Models that describe dormancy and flowering are presented; pollen incompatibility is considered; and the time available for pollination is analyzed. The physiology of fruit set is discussed together with methods to improve fruit set. The next three sections detail methods of manipulating fruiting, either physically by altering plant canopy structure and therefore light interception, genetically by breeding and selection, or chemically by the use of plant growth regulators. This book concludes with a look towards the future using genetic manipulation to alter fruit physiology. This text will be a valuable resource for crop researchers, plant physiologists, geneticists, and others interested in the state of research into fruiting.
