Available in PDF, EPUB and Kindle. Book excerpt: Mycology, the study of fungi, originated as a subdiscipline of botany and was a des criptive discipline, largely neglected as an experimental science until the early years of this century. A seminal paper by Blakeslee in 1904 provided evidence for self incompatibility, termed "heterothallism", and stimulated interest in studies related to the control of sexual reproduction in fungi by mating-type specificities. Soon to follow was the demonstration that sexually reproducing fungi exhibit Mendelian inheritance and that it was possible to conduct formal genetic analysis with fungi. The names Burgetf, Kniep and Lindegren are all associated with this early period of fungal genet ics research. These studies and the discovery of penicillin by Fleming, who shared a Nobel Prize in 1945, provided further impetus for experimental research with fungi. Thus began a period of interest in mutation induction and analysis of mutants for biochemical traits. Such fundamental research, conducted largely with Neurospora crassa, led to the one gene: one enzyme hypothesis and to a second Nobel Prize for fungal research awarded to Beadle and Tatum in 1958. Fundamental research in biochemical genetics was extended to other fungi, especially to Saccharomyces cerevisiae, and by the mid-1960s fungal systems were much favored for studies in eukaryotic molecular biology and were soon able to compete with bacterial systems in the molecular arena.
Download or read book The Reference Collection written by Linda S Katz and published by Routledge. This book was released on 2013-09-05 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stay up-to-date with the growing amount of reference resources available online How important is the World Wide Web to information retrieval and communication? Important enough that information professionals have seen students exit from their libraries en masse when Internet service was lost. Internet providers dominate the indexing and abstracting of periodical articles as major publishers now offer nearly all of their reference titles in digital form. Libraries spend increasing amounts of funding on electronic reference materials, and librarians devote an increasing amount of time to assisting in their use. The Reference Collection: From the Shelf to the Web is an essential guide to collection development for electronic materials in academic and public libraries. The Reference Collection: From the Shelf to the Web tracks the continuing evolution of electronic reference resources-and how they’re accessed—in a variety of settings. Librarians representing university, elementary school, and public libraries in the United States and Australia examine how reference collections have evolved over time (and may soon be a thing of the past); how public and school libraries have dealt with the changes; why library research assignments have become more difficult for teachers to make and for students to complete; how to organize online reference sources; and why the nature of plagiarism has changed in the electronic era. The book also examines the use of electronic references from a publisher’s perspective and looks at the most important Web-accessible reference tools—both free and subscription—in the areas of humanities, medicine, the social sciences, business, and education. The Reference Collection: From the Shelf to the Web also examines: issues of authority, accessibility, cost, comfort, and user education in evaluating electronic resources the formation of purchasing consortia to facilitate the transfer of reference materials from print to online formats current literature and research findings on the state of digital versus print reference collections what electronic publishing means to smaller reference books (dictionaries, almanacs, etc.) the need for increased information literacy among students the nature, extent, and causes of cyber plagiarism the use of federated search tools and includes a selected list of the top 100 free Internet reference sites The Reference Collection: From the Shelf to the Web is an essential resource for all reference and collection development librarians, and an invaluable aid for publishing professionals.

Download or read book Sugarcane Improvement Through Breeding written by D.J Heinz and published by Elsevier. This book was released on 2015-08-11 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a comprehensive survey of breeding principles and practices employed by sugarcane growers and researchers throughout the world. Included within its scope are important genera and species concepts, morphological information, clarification of certain generic names, a description of germplasm collection and utilization, discussion of the complex issues involved in genetic manipulation, and a summary of sugarcane improvement through breeding over the past century. The book is compiled so that information proceeds from the general to the specific. Basic concepts of evolution, taxonomy, morphology, and anatomy form the groundwork for information regarding germplasm collection, cyto-genetics, genetics, and flowering. Methods of practical application are presented in the ensuing chapters, which deal with hybridization, tissue culture, seed handling, selection criteria, and breeding for tolerance. Figures, tables, and photographs accompany text where appropriate. All key words are indexed and extensive bibliographies follow each chapter.

Download or read book Biodiversity of Fungi written by Mercedes S. Foster and published by Elsevier. This book was released on 2011-04-28 with total page 797 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biodiversity of Fungi is essential for anyone collecting and/or monitoring any fungi. Fascinating and beautiful, fungi are vital components of nearly all ecosystems and impact human health and our economy in a myriad of ways. Standardized methods for documenting diversity and distribution have been lacking. A wealth of information, especially regrading sampling protocols, compiled by an international team of fungal biologists, make Biodiversity of Fungi an incredible and fundamental resource for the study of organismal biodiversity. Chapters cover everything from what is a fungus, to maintaining and organizing a permanent study collection with associated databases; from protocols for sampling slime molds to insect associated fungi; from fungi growing on and in animals and plants to mushrooms and truffles. The chapters are arranged both ecologically and by sampling method rather than by taxonomic group for ease of use. The information presented here is intended for everyone interested in fungi, anyone who needs tools to study them in nature including naturalists, land managers, ecologists, mycologists, and even citizen scientists and sophiscated amateurs. - Covers all groups of fungi - from molds to mushrooms, even slime molds - Describes sampling protocols for many groups of fungi - Arranged by sampling method and ecology to coincide with users needs - Beautifully illustrated to document the range of fungi treated and techniques discussed - Natural history data are provided for each group of fungi to enable users to modify suggested protocols to meet their needs
