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.
Download or read book The Poisoned Weed written by Donald G. Crosby and published by Oxford University Press. This book was released on 2004-04-01 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over-two thirds of the U.S. population is allergic to poison oak, poison ivy, or a related plant. These and many other common plants in our homes, fields, and gardens are irritants that cause misery to many. But surprisingly, there has never been a general guide to help raise awareness of them--and to help avoid them. This new book reviews the history, occurrence, classification, toxicity, and health aspects of all the major allergenic and irritant species.

Available in PDF, EPUB and Kindle. Book excerpt: Frontiers of Industrial Mycology describes the present efforts underway to create a broad range of large-scale applications using filamentous fungi. Important and environmentally sound applications currently being developed include the use of fungi for novel *B-lactams in antibiotic production, biobleaching and the bioconversion of wood pulp, agricultural biotechnology for creating biological insecticides and herbicides, food fermentations, and the commercial raising of shiitake mushrooms, a growing and largely untapped market in North America. The topics discussed in this volume are on the cutting edge of industrial mycology. This book will thus benefit a wide range of professionals and academics in biotechnology, mycology, microbiology, plant science, entomology, and biochemistry.
Download or read book Biology of Hevea Rubber written by P.M. Priyadarshan and published by Springer. This book was released on 2017-06-09 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the second edition of this book, the origin, upkeep and latex harvest from the Hevea rubber tree are dealt with succinctly. New chapters have been included on Propagation Systems and Genetic Resources. The importance of Heterozygosis and Breeding is a new theme for the section on Breeding. A new chapter on Genomics and Molecular Breeding that focuses on the latest advancements on gene mapping, marker assisted selection and stimulation has been added. Lastly, ‘textboxes’ that highlight points and topics of significant interest are included in the new addition. Natural rubber has been an essential commodity not only for the tire industry but also for more than 50,000 products that holds elasticity as an attribute. The prime source of natural rubber worldwide is Hevea brasiliensis. Hevea rubber tree is an excellent example of how a soil-tree-atmosphere system can work in tandem. The retrieval of rubber through ‘injuring’ the tree on alternate days or once in three days or once in seven days, is indeed a unique arrangement followed universally that ensures income to the planter almost throughout the year. Every molecule of rubber is the end result of meticulous biochemical changes. Therefore the biology of Hevea rubber tree itself is a subject that aggregates science and technology for the realization of its industrial utility.
Download or read book Genetic Engineering of Plant Secondary Metabolism written by Brian E. Ellis and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this volume of Recent Advances in Phytochmistry you will find a record of the pioneering attempts of plant biochemists and molecular biologists to modify the patterns of secondary metabolism in plants, as presented at the 33rd annual meeting of the Phytochemical Society of North America, in Asilomar, California, on June 27 -July I, 1993. The studies described here represent a marriage of the newest of technologies with one of the oldest human activities, exploitation of plant chemistry. They also represent the beginning of a new era of phytochemical research, an era that will undoubtedly begin to provide answers to some of the long-standing questions that have absorbed plant biochemists for the past century. There is, for instance, a common deflating experience to which every worker in the area of plant secondary metabolism can probably relate. After hearing about the latest research findings regarding some aspect of remarkable compound "X", someone in the audience finally directs the inevitable question at the hapless speaker. "Tell me, is anything known as to the biological role of compound "X" in the plant?" The answer, in most cases, must be "essentially nothing"! This is a frustrating scenario for both the speaker and the audience, since the very fact that a complex biosynthetic pathway remains encoded in a plant genome points to an associated selective advantage. The problem is that establishing the nature and scale of that advantage is a very complex task.

Book excerpt: The updated edition of the classic, fundamental book on weedscience Weed Science provides a detailed examination ofthe principles of integrated weed management with important detailson how chemical herbicides work and should be used. This revisedFourth Edition addresses recent developments affecting weedscience. These include the increased use of conservation-tillagesystems, environmental concerns about the runoff of agrochemicals,soil conservation, crop biotechnology, resistance of weeds andcrops to herbicides, weed control in nonagricultural settings andconcerns regarding invasive plants, wetland restoration, and theneed for a vastly improved understanding of weed ecology. Current management practices are covered along with guidance forselecting herbicides and using them effectively. To serve as a moreefficient reference, herbicides are cross-listed by chemical andbrand name and grouped by mechanism of action and physiologicaleffect rather than chemical structure. In addition, an introductionto organic chemistry has been added to familiarize readers withorganic herbicides. Also included are guidelines on weed-controlpractices for specific crops or situations, such as small grains,row crops, horticultural crops, lawns and turf, range land, brush,and aquatic plant life. Generously supplemented with 300 drawings, photographs, andtables, Weed Science is an essential book for students taking anintroductory course in weed science, as well as a reference foragricultural advisors, county agents, extension specialists, andprofessionals throughout the agrochemical industry.
Download or read book Modern Trends in Applied Terrestrial Ecology written by R.S. Ambasht and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecology and economics have Greek roots in oikos for "household", logos for "study", and nomics for "management". Thus, ecology and economics should have complemented one another for a proper growth and development without destruction, but, unfortunately, rapid industrialization, lure for fast financial gains, and commercialization activities have led to a widespread surge in pollution load, environmental degradation, habitat destruction, rapid loss ofbiodiversity, sudden rise in rate ofextinction ofmany wildlife and wild relatives of domesticated animals and cultivated cereals and other plants, global climate changes creating global rise in temperature, and CO levels and increased ultraviolet B at ground 2 level. Although these threats to human health have led us to look to ecology for their solutions and guidance for sustainable development without destruction, the industrial and technology houses are looking for alternative methods of development and resource use methods. The two global conferences of the United Nations in 1972 and 1992, and international programs of Man and the Biosphere (MAB), International Biological Program (IBP), International Geosphere, Biosphere program (lGBP), and World Conser vation Union (IUCN), of different commissions, United Nations Environmental Program (UNEP) efforts, Ramsar Conventions (for wetlands), and World Wide fund for Nature (WWF) (for nature in general and wildlife in particular) have focused attention of ecologists, naturalists, governments and Non-governmental organizations (NGOs) toward better conservation.
