Senescence and Aging in Plants by L.D. Nooden Pdf

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.

Plant Aging by Roberto Rodríguez,R.Sanchez Tamés,D.J. Durzan Pdf

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.

Senescence Signalling and Control in Plants by Maryam Sarwat,Narendra Tuteja Pdf

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.

Processes and Control of Plant Senescence by Y.Y. Leshem,A.H. Halevy,C. Frenkel Pdf

This monograph provides basic and empiric information underlying processes believed to be involved in the doubtless multifunctional plant senescence syndrome. While essentially assuming a `basic science' approach the authors, drawing on data obtained from many of the main laboratories and research centres involved in senescence research the world over, and also on findings of the research groups they are associated with, have described how principles of basic science have been applied to practical problems, and have outlined the partial means presently available to man for achieving plant senescence control. Moreover, information is provided on current problems in the forefront of senescence research. This approach will hopefully engender further enquiry and lead at least to partial solutions to some of the as yet unsolved problems.The book will be an asset to the book shelves of students on advanced courses in agriculture, biology and biochemistry as well as scientists and research workers, university and agricultural research station libraries and horticulturalists.

Natural Anti-Aging Plants and Delay of Senescence by Noboru Motohashi Pdf

"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"--

Plant Hormones by Peter J. Davies Pdf

Plant hormones play a crucial role in controlling the way in which plants grow and develop. While metabolism provides the power and building blocks for plant life, it is the hormones that regulate the speed of growth of the individual parts and integrate them to produce the form that we recognize as a plant. This book is a description of these natural chemicals: how they are synthesized and metabolized, how they act at both the organismal and molecular levels, how we measure them, a description of some of the roles they play in regulating plant growth and development, and the prospects for the genetic engineering of hormone levels or responses in crop plants. This is an updated revision of the third edition of the highly acclaimed text. Thirty-three chapters, including two totally new chapters plus four chapter updates, written by a group of fifty-five international experts, provide the latest information on Plant Hormones, particularly with reference to such new topics as signal transduction, brassinosteroids, responses to disease, and expansins. The book is not a conference proceedings but a selected collection of carefully integrated and illustrated reviews describing our knowledge of plant hormones and the experimental work that is the foundation of this information. The Revised 3rd Edition adds important information that has emerged since the original publication of the 3rd edition. This includes information on the receptors for auxin, gibberellin, abscisic acid and jasmonates, in addition to new chapters on strigolactones, the branching hormones, and florigen, the flowering hormone.

Annual Plant Reviews, Senescence Processes in Plants by Susheng Gan Pdf

The scientific and economic significance of plant senescence means that much effort has been made to understand the processes involved and to devise means of manipulating them agriculturally. During the past few years there has been considerable progress in this regard, especially in the molecular, genetic and genomic aspects. Senescence has a tremendous impact on agriculture. For example, leaf senescence limits crop yield and biomass production, and contributes substantially to postharvest loss in vegetable and ornamental crops during transportation, storage and on shelves. In addition, proteins, antioxidants and other nutritional compounds are degraded during senescence. Senescing tissues also become more susceptible to pathogen infection, and some of the pathogens may produce toxins, rendering food unsafe. Mitotic senescence may also determine sizes of leaves, fruits and whole plants. This volume summarizes recent progresses in the physiology, biochemistry, cell biology, molecular biology, genomics, proteomics, and biotechnology of plant senescence. Beginning with a chapter on senescence-related terminology and our current knowledge of mitotic senescence in plants (a less well-studied area), the book focuses on post-mitotic senescence, and includes chapters addressing the senescence of leaves, flowers and fruits. Later chapters examine the development of various new biotechnologies for manipulating the senescence processes of fruit and leaves, some of which are approaching commercialization. The book is directed at researchers and professionals in plant molecular genetics, physiology and biochemistry.

The Biology of Senescence by Bernard Swynghedauw Pdf

This book describes the fundamental process of senescence, and reviews a new concept developed by a number of research groups that is based on cellular senescence and its secretome. This concept provides a basic explanation of the main physiological and pathological features of senescence, and delineates possibilities for “treating” it. Following an introduction to the emerging medical landscape, the increasing incidence of a new epidemiological group (age-related “chronic non-transmissible diseases”), and the multiple origins of aging, the book explores and characterizes the senescent cell, which is linked to benign and pathological age-related manifestations. In turn, the closing chapters discuss how to “treat” or “prevent” the aging process, underscoring the central role of physical exercise and caloric reduction as compared to new senolytic approaches. Appendices are also provided, and address circadian rhythms, telomere shortening, diabetic cardiomyopathy, and senescence in plants and bacteria. Given its scope, the book will primarily be of interest to geriatricians, but will also appeal to a wider range of clinicians.
