Book Synopsis Senescence and Aging in Plants by : L.D. Nooden
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 Viability of Seeds written by E.H. Roberts and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: From prehistoric times man has had a pecial s relationship with seed plants - as a source of food, materials for tools, buildings, clothing and pharmaceuticals, and for ornamenting his surroundings for his own delight (probably in that chronological order which, incidentally, also gives some indication ofthe priorities oflife). Today man's most important staple foods are derived directly from seeds as they have been since neolithic times. (It is a sobering thought, as Harlan* has pointed out, that nothing significant has been added to his diet since then. ) From those times he must have learned to collect, conserve and cultivate seeds; and the accumulated experience has been handed down. This book then is part of an ancient tradition, for here we are still primarily concerned with these skills. Seeds are plant propagules comprised of embryos in which growth has been suspended, usually supplied with their own food reserves and protected by special covering layers. Typically they are relatively dry structures compared with other plant tissues and, in this condi tion) they are resistant to the ravages of time and their environment. But resistant is a relative tenn and seeds do deteriorate: the type, the extent and the rapidity of the deterioration, and the factors which control it are important to agronomists, horticulturalists, plant breeders, seedsmen, seed analysts, and those concerned with the conservation of genetic resources.

Book Synopsis A Protocol to Determine Seed Storage Behaviour by : T. D. Hong
Download or read book A Protocol to Determine Seed Storage Behaviour written by T. D. Hong and published by Bioversity International. This book was released on 1996 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication provides an approach by which conservationists can determine whether or not long-term seed storage is feasible for a particular species, i.e. whether or not that species shows orthodox seed storage behaviour, and provides advice on the implementation of the protocol, examples of ways in which the results from seed storage studies could be misinterpreted due to confounding factors, as well as several alternative approaches for estimating seed storage behaviour prior to carryng out actual investigations with the seeds. In particular, the latter section introduces the concept of a multicriteria approach for estimating seed storage behaviour.
Book Synopsis Stupid Things I Won't Do When I Get Old by : Steven Petrow
Download or read book Stupid Things I Won't Do When I Get Old written by Steven Petrow and published by Citadel. This book was released on 2021-06-29 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: For fans of David Sedaris and Nora Ephron, a humorous, irreverent, and poignant look at the gifts, stereotypes, and inevitable challenges of aging, based on award-winning journalist Steven Petrow's wildly popular New York Times essay, "Things I'll Do Differently When I Get Old." Soon after his 50th birthday, Petrow began assembling a list of “things I won’t do when I get old”—mostly a catalog of all the things he thought his then 70-something year old parents were doing wrong. That list, which included “You won’t have to shout at me that I’m deaf,” and “I won’t blame the family dog for my incontinence,” became the basis of this rousing collection of do’s and don’ts, wills and won’ts that is equal parts hilarious, honest, and practical. The fact is, we don’t want to age the way previous generations did. “Old people” hoard. They bore relatives—and strangers alike—with tales of their aches and pains. They insist on driving long after they’ve become a danger to others (and themselves). They eat dinner at 4pm. They swear they don’t need a cane or walker (and guess what happens next). They never, ever apologize. But there is another way... In Stupid Things I Won’t Do When I Get Old, Petrow candidly addresses the fears, frustrations, and stereotypes that accompany aging. He offers a blueprint for the new old age, and an understanding that aging and illness are not the same. As he writes, “I meant the list to serve as a pointed reminder—to me—to make different choices when I eventually cross the threshold to ‘old.’” Getting older is a privilege. This essential guide reveals how to do it with grace, wisdom, humor, and hope. And without hoarding. Praise for Stupid Things I Won't Do When I Get Old: “Unbelievably witty and relatable, I alternated bursting into laughter and placing my hand over my face in horror thinking, Oh my God, is that me? I often say, at this age we have something young people can never have…wisdom. My dear friend, Steven Petrow, has wisdom to share in this honest, funny, wry guide to keep us young at heart, without desperately hanging onto our youth. I am buying this book for all of my friends!” —Suzanne Somers, New York Times bestselling author of A New Way to Age “Stupid Things I Won’t Do When I Get Old is an irreverent, funny, honest look at aging and all the things we take for granted as normal parts of aging. They don’t need to be. If you struggle with getting older and want to find a fresh perspective on lessons learned about what NOT to do as we age, and what TO do to stay young in heart, spirit, mind and body, read this book.” —Mark Hyman, MD, #1 New York Times bestseller author of The Blood Sugar Solution 10-Day Detox Diet, and Head of Strategy and Innovation at the Cleveland Clinic Center for Functional Medicine. “Steven Petrow resolved to do things differently than his parents had when he gets old because he wished they’d been able to enjoy life more. His solution? He created a list! In this book, he shares the secrets to living a full life regardless of our age. It's all about the decisions we make every day. My advice in a nutshell: Read this book and keep it handy.” —“Dear Abby” (Jeanne Phillips), nationally syndicated advice columnist “It’s never too early to imagine what your life will look like as you age. And as I once wrote, ‘We are not hostages to our fate.’ Petrow’s book will help you plan, think, and redefine what it means to get older—and even laugh while doing it.” —Andrew Weil, MD, New York Times bestselling author of Spontaneous Healing and Healthy Aging: A Lifelong Guide to Your Well-Being “Steven Petrow not only has a great attitude about life, he is wise about how to live it. Like me, he says we should embrace our one life 100% and not let a number—our age—get in the way of anything! Steven’s book will help you rethink the word “aging” and approach this next chapter with a positive and proactive attitude. Plus, this book is fun!” —Denise Austin, renowned fitness expert, author, and columnist “Steven’s writing feels like sitting with a friend—one who is unusually gracious, warm and frank.” —Carolyn Hax, author of the nationally syndicated advice column, Carolyn Hax Praise for Steven Petrow: "Steven Petrow's Complete Gay & Lesbian Manners helps gays and straights navigate the subtleties of the same-sex world." —People "Move over, Emily Post! When it comes to etiquette for members of the gay, lesbian, bisexual and transgender community—as well as their straight friends, family members and coworkers--author and journalist Steven Petrow is the authority." —TIME "What could've easily become a novelty book has emerged as an exhaustively researched, essential resource thanks to advice columnist and etiquette expert Steven Petrow." —The Advocate "From having kids to planning funerals, Steven Petrow's Complete Gay & Lesbian Manners has most facets of gay life covered. Ms. Post would approve." —Entertainment Weekly "An indispensable refresher course...on what's proper in modern...life." —Kirkus Reviews
Book Synopsis How Men Age by : Richard G. Bribiescas
Download or read book How Men Age written by Richard G. Bribiescas and published by Princeton University Press. This book was released on 2018-05-08 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: A groundbreaking book that examines all aspects of male aging through an evolutionary lens While the health of aging men has been a focus of biomedical research for years, evolutionary biology has not been part of the conversation—until now. How Men Age is the first book to explore how natural selection has shaped male aging, how evolutionary theory can inform our understanding of male health and well-being, and how older men may have contributed to the evolution of some of the very traits that make us human. In this informative and entertaining book, renowned biological anthropologist Richard Bribiescas looks at all aspects of male aging through an evolutionary lens. He describes how the challenges males faced in their evolutionary past influenced how they age today, and shows how this unique evolutionary history helps explain common aspects of male aging such as prostate disease, loss of muscle mass, changes in testosterone levels, increases in fat, erectile dysfunction, baldness, and shorter life spans than women. Bribiescas reveals how many of the physical and behavioral changes that we negatively associate with male aging may have actually facilitated the emergence of positive traits that have helped make humans so successful as a species, including parenting, long life spans, and high fertility. Popular science at its most compelling, How Men Age provides new perspectives on the aging process in men and how we became human, and also explores future challenges for human evolution—and the important role older men might play in them.

Book Synopsis Annual Plant Reviews, Seed Development, Dormancy and Germination by : Kent Bradford
Download or read book Annual Plant Reviews, Seed Development, Dormancy and Germination written by Kent Bradford and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: The formation, dispersal and germination of seeds are crucial stages in the life cycles of gymnosperm and angiosperm plants. The unique properties of seeds, particularly their tolerance to desiccation, their mobility, and their ability to schedule their germination to coincide with times when environmental conditions are favorable to their survival as seedlings, have no doubt contributed significantly to the success of seed-bearing plants. Humans are also dependent upon seeds, which constitute the majority of the world’s staple foods (e.g., cereals and legumes). Seeds are an excellent system for studying fundamental developmental processes in plant biology, as they develop from a single fertilized zygote into an embryo and endosperm, in association with the surrounding maternal tissues. As genetic and molecular approaches have become increasingly powerful tools for biological research, seeds have become an attractive system in which to study a wide array of metabolic processes and regulatory systems. Seed Development, Dormancy and Germination provides a comprehensive overview of seed biology from the point of view of the developmental and regulatory processes that are involved in the transition from a developing seed through dormancy and into germination and seedling growth. It examines the complexity of the environmental, physiological, molecular and genetic interactions that occur through the life cycle of seeds, along with the concepts and approaches used to analyze seed dormancy and germination behavior. It also identifies the current challenges and remaining questions for future research. The book is directed at plant developmental biologists, geneticists, plant breeders, seed biologists and graduate students.

Download or read book Plant Aging written by Roberto Rodríguez and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 425 pages. 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.

Book Synopsis Albion's Seed by : David Hackett Fischer
Download or read book Albion's Seed written by David Hackett Fischer and published by Oxford University Press. This book was released on 1991-03-14 with total page 981 pages. Available in PDF, EPUB and Kindle. Book excerpt: This fascinating book is the first volume in a projected cultural history of the United States, from the earliest English settlements to our own time. It is a history of American folkways as they have changed through time, and it argues a thesis about the importance for the United States of having been British in its cultural origins. While most people in the United States today have no British ancestors, they have assimilated regional cultures which were created by British colonists, even while preserving ethnic identities at the same time. In this sense, nearly all Americans are "Albion's Seed," no matter what their ethnicity may be. The concluding section of this remarkable book explores the ways that regional cultures have continued to dominate national politics from 1789 to 1988, and still help to shape attitudes toward education, government, gender, and violence, on which differences between American regions are greater than between European nations.
