Senescence and Aging in Plants reviews the state of knowledge in the processes involved in plant senescence and aging. The book begins by discussing the emergence of senescence as a concept; experimental analysis of senescence; and patterns of senescence. It then examines membrane deterioration during senescence; photosynthesis in relation to leaf senescence; senescence of detached plant organs; changing patterns of nucleic acid and protein synthesis during senescence; and degradative and associated assimilatory aspects of nitrogen removal. This is followed by chapters on aspects of ethylene that may impinge upon its role in promoting senescence of higher plants; the role of cytokinins in plant senescence; the promoters and retardants of senescence; and the role of calcium in plant senescence. The concept of whole plant senescence is discussed, which can be subdivided into patterns, correlative controls, cessation of vegetative growth, declining assimilatory processes, assimilate partitioning, and hormonal controls. The final chapters cover the deterioration of cellular membranes during the plant aging process and seed aging.

Senescence Signalling and Control in Plants discusses the studies showing the importance of hormone action on developmental senescence. It shows the involvement of various signaling components (such as EIN2, LOX2) and transcription factors (such as oresara1 or ORE1) in controlling hormonal activity during senescence. Further, the involvement of various micro RNAs (miR164, miR319) in regulating leaf senescence are discussed. Through this book, the authors throw light on all the reverse and forward genetic approaches to reveal the role of various other phytohormones regulating plant senescence and the molecular mechanisms involved. Chapters on relevant topics are contributed by experts working in the area, making this a comprehensive treatise designed to provide an in-depth analysis on the subject matter.

For many, the terms aging, maturation and senescence are synonymous and used interchangeably, but they should not be. Whereas senescence represents an endogenously controlled degenerative programme leading to plant or organ death, genetiC aging encompasses a wide array of passive degenerative genetiC processes driven primarily by exogenous factors (Leopold, 1975). Aging is therefore considered a consequence of genetiC lesions that accumulate over time, but by themselves do not necessarily cause death. These lesions are probably made more severe by the increase in size and complexity in trees and their attendant physiology. Thus while the withering of flower petals following pollination can be considered senescence, the loss of viability of stored seeds more clearly represents aging (Norden, 1988). The very recent book "Senescence and Aging in Plants" does not discuss trees, the most dominant group of plants on the earth. Yet both angiospermic and gymnospermic trees also undergo the above phenomena but less is known about them. Do woody plants senesce or do they just age? What is phase change? Is this synonymous with maturation? While it is now becoming recognized that there is no programmed senescence in trees, senescence of their parts, even in gymnosperms (e. g. , needles of temperate conifers las t an average of 3. 5 years), is common; but aging is a readily acknowledged phenomenon. In theory, at least, in the absence of any programmed senescence trees should -live forever, but in practice they do not.

The existing theories on the evolution of senescence assume that senescence is inevitable in all organisms. However, recent studies have shown that this is not necessarily true. A better understanding of senescence and its underlying mechanisms could have far-reaching consequences for conservation and eco-evolutionary research. This book is the first to offer interdisciplinary perspectives on the evolution of senescence in many species, setting the stage for further developments. It brings together new insights from a wide range of scientific fields and cutting-edge research done on a multitude of different animals (including humans), plants and microbes, giving the reader a complete overview of recent developments and of the controversies currently surrounding the topic. Written by specialists from a variety of disciplines, this book is a valuable source of information for students and researchers interested in ageing and life history traits and populations.

Plant Hormones: Biosynthesis and Mechanisms of Action is based on research funded by the Chinese government’s National Natural Science Foundation of China (NSFC). This book brings a fresh understanding of hormone biology, particularly molecular mechanisms driving plant hormone actions. With growing understanding of hormone biology comes new outlooks on how mankind values and utilizes the built-in potential of plants for improvement of crops in an environmentally friendly and sustainable manner. This book is a comprehensive description of all major plant hormones: how they are synthesized and catabolized; how they are perceived by plant cells; how they trigger signal transduction; how they regulate gene expression; how they regulate plant growth, development and defense responses; and how we measure plant hormones. This is an exciting time for researchers interested in plant hormones. Plants rely on a diverse set of small molecule hormones to regulate every aspect of their biological processes including development, growth, and adaptation. Since the discovery of the first plant hormone auxin, hormones have always been the frontiers of plant biology. Although the physiological functions of most plant hormones have been studied for decades, the last 15 to 20 years have seen a dramatic progress in our understanding of the molecular mechanisms of hormone actions. The publication of the whole genome sequences of the model systems of Arabidopsis and rice, together with the advent of multidisciplinary approaches has opened the door to successful experimentation on plant hormone actions. Offers a comprehensive description of all major plant hormones including the recently discovered strigolactones and several peptide hormones Contains a chapter describing how plant hormones regulate stem cells Offers a fresh understanding of hormone biology, particularly molecular mechanisms driving plant hormone actions Discusses the built-in potential of plants for improvement of crops in an environmentally friendly and sustainable manner

"Worldwide, human life is headed for longevity. On the other hand, humans have a desire to stay healthy and live longer. However, synthetic drugs are immediately effective, but some drugs can cause serious side effects. From about 100 to 150 years ago, humans have used all diseases for treatment and prevention, using natural resources such as plants, animals and minerals. These natural ingredients can minimize side effects etc. even after long-term administration. In addition, these natural ingredients can also control chronic toxicity etc. in a concentration-dependent manner. Based on these ideas, this book will focus on plant ingredients and plants that can be expected to maintain health until this longevity"--
