Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Senescence and Aging in Plants written by L.D. Nooden and published by Elsevier. This book was released on 2012-12-02 with total page 555 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Processes and Control of Plant Senescence written by Y.Y. Leshem and published by Elsevier. This book was released on 2012-12-02 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Annual Plant Reviews Senescence Processes in Plants written by Susheng Gan and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: From the author of the New York Times bestseller The Plant Paradox comes a groundbreaking plan for living a long, healthy, happy life. From the moment we are born, our cells begin to age. But aging does not have to mean decline. World-renowned surgeon Dr. Steven Gundry has been treating mature patients for most of his career. He knows that everyone thinks they want to live forever, until they hit middle age and witness the suffering of their parents and even their peers. So how do we solve the paradox of wanting to live to a ripe old age—but enjoy the benefits of youth? This groundbreaking book holds the answer. Working with thousands of patients, Dr. Gundry has discovered that the “diseases of aging” we most fear are not simply a function of age; rather, they are a byproduct of the way we have lived over the decades. In The Longevity Paradox, he maps out a new approach to aging well—one that is based on supporting the health of the “oldest” parts of us: the microorganisms that live within our bodies. Our gut bugs—the bacteria that make up the microbiome—largely determine our health over the years. From diseases like cancer and Alzheimer’s to common ailments like arthritis to our weight and the appearance of our skin, these bugs are in the driver’s seat, controlling our quality of life as we age. The good news is, it’s never too late to support these microbes and give them what they need to help them—and you—thrive. In The Longevity Paradox, Dr. Gundry outlines a nutrition and lifestyle plan to support gut health and live well for decades to come. A progressive take on the new science of aging, The Longevity Paradox offers an action plan to prevent and reverse disease as well as simple hacks to help anyone look and feel younger and more vital.

Available in PDF, EPUB and Kindle. Book excerpt: "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"--

Available in PDF, EPUB and Kindle. Book excerpt: From the winner of the National Garden Club's Award of Excellence Although the garden may beckon as strongly as ever, the tasks involved—pulling weeds, pushing wheelbarrows, digging holes, moving heavy pots—become increasingly difficult, or even impossible, with advancing age. But the idea of giving it up is unthinkable for most gardeners. So what’s the alternative? In Gardening for a Lifetime, Sydney Eddison draws on her own forty years of gardening to provide a practical and encouraging roadmap for scaling back while keeping up with the gardening activities that each gardener loves most. Like replacing demanding plants like delphiniums with sturdy, relatively carefree perennials like sedums, rudbeckias, and daylilies. Or taking the leap and hiring help—another pair of hands, even for a few hours a week, goes a long way toward getting a big job done. This new edition features an additional chapter describing how Sydney’s struggles with hip and back problems forced her to walk the walk. As a friend of hers says, “Last summer you wrote the book. Now, I’m happy to see that you’ve read it.” Gentle, personable, and practical, Gardening for a Lifetime will be welcomed by all gardeners looking to transform gardening from a list of daunting chores into the gratifying, joyful activity it was meant to be.
