Download or read book Current Advances in Fern Research written by Helena Fernández and published by Springer. This book was released on 2018-03-24 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ferns, collectively, represent an ancient species of vascular plant which has a direct connection to the beginning of life on Earth. Today they are valued for their ornamental appeal, environmental benefit or as sources of health benefiting metabolites. Current pteridology, the study of fern, encompasses a wide range of research activities including, but not limited to, plant physiology, stress tolerance, genetics and genomics. The goal of this book is to compile the most relevant research done with ferns during the last decade. It is organized into four parts: I, Biology and Biotechnology; II, Evolution and Conservation; III, Metabolism and Genetic Resources, and IV, Environment. Each section reveals the utilization of ferns as a tool to explore challenges unique to plant development and adaptation. This project represents our collective effort to raise the awareness of ferns as a model system to study higher plant functions. Among the distinctive features of our proposed book are: (i) a wide range of topics with contributing researchers from all around the world, and (ii) recent advances of theoretic and applied knowledge with implications to crop species of economic value.
Download or read book Biotechnology and Ecology of Pollen written by David L. Mulcahy and published by Springer. This book was released on 2011-11-11 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Recognition of the Forgotten Generation D. L. MULCAHyl Pollen was long believed to serve primarily a single function, that of delivering male gametes to the egge A secondary and generally overlooked value of pollen is that it serves to block the transmission of many defective alleles and gene combinations into the next generation. This latter function comes about simply because pollen tubes carrying defective haploid genotypes frequently fail to complete growth through the entire length of the style. However, the beneficial consequences of this pollen selection are diluted by the fact that the same deleterious genotypes are often transmitted through the egg at strictly mendelian frequencies (Khush, 1973). Gene expression in the pollen might thus at least appear to be a phenomenon of trivial consequence. Indeed, Heslop-Harrison (1979) rightly termed the gametophytic portion of the angiosperm life cycle, the "forgotten generation." This neglect, however, came about despite subtle but constant indications that pollen is the site of intense gene activity and selection. For example, Mok and Peloquin (1975) demonstrated that relatively heterozygous diploid pollen shows heterotic characteristics whereas relatively homozygous diploid pOllen does not. This was proof positive that genes are expressed (that is, transcribed and translated) in the pollen. 1 Department of Botany, University of Massachusetts Amherst, MA 01003, USA viii However, the implications for pollen biology of even this recent and well known study were not widely recognized.
Download or read book Cytogenetics written by J. Schulz-Schaeffer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 1961 the author has taught a course in Cytogenetics at Montana State University. Undergraduate and graduate stu dents of Biology, Chemistry, Microbiology, Animal and Range Science, Plant and Soil Science, Plant Pathology and Veterinary Science are enrolled. Therefore, the subject matter has been pre sented in an integrated way to correlate it with these diverse disciplines. This book has been prepared as a text for this course. The most recent Cytogenetics text was published in 1972, and rapidly developing research in this field makes a new one urgently needed. This book includes many aspects of Cytogenetics and related fields and is written for the college student as well as for the researcher. It is recommended that the student should have taken preparatory courses in Principles of Genetics and Cytol ogy. The content is more than is usually taught during one quar ter of an academic year, thus allowing an instructor to choose what he or she would like to present to a class. This approach also allows the researcher to obtain a broad exposure to this field of biology. References are generously supplied to stimulate orig inal reading on the subject and to give access to valuable sources. The detailed index is intended to be of special assistance to researchers.
