Pollen transmits the male genetic material in sexual reproduction of all higher plants. This same pollen is also well suited as a research tool for studying many patterns of plant and animal metabolism. In addition, an increased knowledge of pollen may help plant breeders accelerate efforts to improve the world's food and fiber supply. This volume focuses upon pollen biology and chemistry; it attempts to inte grate these facts with management practices involved in pollen applications. People have long been involved with pollen. Pollen applications are recorded in the rites of ancient civilizations (see Frontispiece). From the earliest times many benefits have been attributed to the inclusion of pollen in man's diet; also, since the mid-19th century air-borne pollen has been recognized as detrimental to many people's health. Disciplines concerned with man's cultural history and the earth's changing ecology find pollen a particularly useful and accessible tool. Identifiable parts of pollen have survived over 100 million years. But most books dealing with pollen are generally concerned with the identification of the plant source, an aspect of the science of palynology; other books emphasize the natural vectors transmit ting pollen, the pollination mechanisms. Very few works include the biochem istry or biology of pollen. Yet extensive studies by physicians, as well as plant breeders and apiculturists, have contributed a sizeable body of research relating to pollen.

Pollen grains are everywhere - in the air, in the water, in soil and in the food we eat. Pollen has direct relevance in agriculture, horticulture, plant breeding, crop improvement and biotechnology. They are further of use for montioring cytotoxic effects - by herbicides, pesticides and pollutants - testing for allergic reactions, and for basic studies on gene expression, research on differentiation and polarity. Detailed instructions of the standard techniques, which have all been tested and improvised by the authors, are given, such as collection and storage of pollen, pollen culture, germination, tests for viability, incompatibility and isolation of protoplasts. Introduced by an explanation of the principles involved, the step-by step protocols are complemented by personal notes and precautions, specifying the reagents used and various appendices on basic and specific requirements for laboratory exercises on pollen.

Pollination Biology reviews the state of knowledge in the field of pollination biology. The book begins by tracing the historical trends in pollination research and the development of the two styles of pollination biology. This is followed by separate chapters on the evolution of the angiosperms; the evolution of plant-breeding systems; the geographical correlations between breeding habit, climate, and mode of pollen transfer; and sexual selection in plants. Subsequent chapters examine the process of sexual selection through gametic competition in Geranium maculatum; the effects of different gene movement patterns on plant population structure; the foraging behavior of pollinators; adaptive nature of floral traits; and competitive interactions among flowering plants for pollinators. The book is designed to provide useful material for advanced undergraduate and graduate students wishing to familiarize themselves with modern pollination biology and also to provide new insights into specific problems for those already engaged in pollination research. The book is intended to be used for both teaching and research.

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.

This volume explores a collection of experimental techniques used to investigate different aspects of pollen development and function, including its role in reaching the ovule and delivering the two sperm cells. The techniques discussed range from basic methodology to cultivate pollen in vitro to the sophisticated experiments involving micromanipulation, Lab-on-Chip technology, or high-end imaging. The chapters in this book cover topics such as pollen grain counting using a cell counter; restricted pollination for tracing individual pollen tubes in a pistil; obtaining mutant pollen for phenotypic analysis and pollen tube dual-staining; analyzing intracellular gradients in pollen tubes; and measuring exocytosis rate in Arabidopsis pollen tube using corrected fluorescence recovery after photoconversion (cFRAPc) technique. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Cutting-edge and thorough, Pollen and Pollen Tube Biology: Methods and Protocols is a valuable resource for novice and expert scientists interested in learning more about the field of plant reproduction.

Pollen Tip Growth written by Gerhard Obermeyer and has been published by Springer this book supported file pdf, txt, epub, kindle and other format this book has been release on 2017-06-13 with Science categories.
This book focuses on the biophysical aspects of tip growth: How do physical parameters like pressure, water potential, electrical fields, or ion currents contribute to and influence this specialized and highly dynamic form of cell growth? It provides an updated and balanced overview of the current state of knowledge and future research perspectives regarding how pollen tubes’ growth is driven and regulated by molecular interactions underlying the cellular processes. The individual chapters address topics ranging from molecular biophysical concepts to comprehensive omic studies and computational modeling of the tip growth process. In addition, a chapter on root hair cells is included to provide an alternative view on the underlying molecular principles of tip growth in general. Each chapter provides a summary of cutting-edge techniques, results and experimental data; a statement, hypothesis or conclusion on the importance of the aspect described for tip growth, particularly pollen tip growth; and addresses open gaps in our understanding and potential approaches to remedying them. The book offers experimental and theoretical solutions to help established researchers and newcomers to the field alike solve the many mysterious behaviors of pollen tube tips.
