This book was released on 2012-12-06 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an excellent illustration of the interrelationship between progress in scientific methodology and conceptual advances, and its publica tion should contribute to further advances. It is well known that major advances in understanding often follow the development of new methods. The development of the acetylene reduction assay for nitrogenase activity provides a good example of this interrelationship between theory and methods. Theoretical knowledge led to a search for substrates for nitro genase that could be assayed for more easily than ammonium, the normal product of the enzyme. The discovery of the reduction of acetylene to ethylene by nitrogenase provided the ideal answer to the problem by provid ing a rapid, specific, nondestructive, and inexpensive assay for nitrogenase activity. This assay is now used by almost every laboratory doing research on nitrogen fixation. However, further use and development of the acetylene reduction assay has shown that it can underestimate nitrogenase activity and can even give incorrect relative values under some circumstances. The major problem is that exposure of legume nodules to acetylene can cause a large increase in the resistance to oxygen diffusion into the nodule. This reduced supply of oxygen decreases the rate of nitrogenase activity within a few minutes.

Download or read book Cell and Tissue Culture in Forestry written by J.M. Bonga and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the first edition of our book "Tissue Culture in Fores try" in 1982 we have witnessed remarkable advances in cell and tissue culture technologies with woody perennials. In addition to forest biologists in government, industry, and universities, we now have molecular biologists, genetic engineers, and biochemists using cell and tissue cultures of woody species routinely. There fore, the time has come for an update of the earlier edition. In our present effort to cover new developments we have expanded to three volumes: 1. General principles and Biotechnology 2. Specific Principles and Methods: Growth and Development 3. Case Histories: Gymnosperms, Angiosperms and Palms The scientific barriers to progress in tree improvement are not so much lack of foreign gene expression in plants but our current inabili ty to regenerate plants in true-to-type fashion on a mas sive and economic scale. To achieve this in the form of an appro pr iate biotechnology, cell and tissue culture will increasing ly require a better understanding of basic principles in chemistry and physics that determine structural and functional relationships among molecules and macromolecules (proteins, RNA, DNA) within cells and tissues. These principles and their relationship with the culture medium and its physical environment, principles of clonal propagation, and genetic variation and ultrastructure are discussed in volume one.

This book was released on 2007-07-02 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book marshals ecological literature from the last century on facilitation to make the case against the widely accepted individualistic notion of community organization. It examines the idea that positive interactions are more prevalent in physically stressful conditions. Coverage also includes species specificity in facilitative interactions, indirect facilitative interactions, and potential evolutionary aspects of positive interactions.

This book was released on 1999 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book investigates the induced responses of plants to herbivores and to diseases. Plant pathologists and entomologists will find that their disciplines have a lot in common when it comes to the interest in the transduction signals of plants that mediate induced responses. Induced Plant Defenses Against Pathogens and Herbivores will allow these two disciplines to converse and learn from their similarities and differences.

Available in PDF, EPUB and Kindle. Book excerpt: As an introduction to the present book I would like to explain how it was, that I, a commercial nurseryman, became so keenly interested in Conifers and their nomen clature. In August 1924 the Dutch Dendrological Society was founded and at the same time a Committee for Nomenclature of woody plants was set up and I served on this committee as one of the members. Our first activity was to bring the catalogues of the various leading nurserymen in the Netherlands into line with the International Rules of Botanical Nomenclature and also to check their nursery stock. Formerly these catalogues had shown a rather confused nomenclature, nurserymen having usually made use of a variety of inconsistent books as guides in compiling their catalogues. In the course of the work a close co-operation between scientific and practical workers developed. Although I had also fully contributed to the correct naming of hardy shrubs and perennials, 1 was most interested in Conifers. I had tried out several species, had grown a wide choice of garden forms and selected types of particular merit for propagation. My special love for Conifers lead to the publication of my Name-list of Conifers (1937), which was adopted as a standard for varietal names at the International Horticultural Congress in Berlin (1938). Later I prepared my book 'Coniferen, Ephedra en Ginkgo' in the Dutch language (1949); compiling the Conifers cultivated or known to be grown in the Netherlands and Belgium at that time.

Book excerpt: This book is based on a meeting on the Fungal Nucleus organised by the Physiology Group of the British Mycological Society and held in London in April 1980. The contributions of the authors provide a detailed picture of the knowledge of the cell nucleus in yeasts, filamentous fungi and slime moulds at the time. These organisms are important model eukaryotes for studies in cell and molecular biology. This volume deals with the ultra structure, biochemistry and genetics of the fungal nucleus and with the regulation of nuclear activity. It provides a useful source of reference for any one interested in the progressive study of mycology, genetics, microbiology and cell biology.
