DOWNLOAD EBOOK →Pollen: Development and Physiology focuses on pollen physiology, with emphasis on the living pollen grains, their growth, and essential biological functions. Topics covered in this book include the role of nucleus and cytoplasm in microsporogenesis; the development of the pollen grain wall; the metabolism of pollen tubes; pistil-pollen interactions; and incompatibility. This monograph is comprised of 35 chapters divided into five sections. The first section explores the physiology and biochemistry of meiosis in the anther; changes in the cytoplasm and its organelles during microsporogenesis; and changes in cytoplasmic RNA and enzyme activity during the meiotic prophase in Cosmos bipinnatus. The next section is devoted to pollen development and the pollen grain wall and includes chapters that look at the role of the tapetum during microsporogenesis of angiosperms; dictyosome development during microsporogenesis in Canna generalis; and pollen grain and sperm cell ultrastructure in Beta. The remaining sections discuss the metabolism of pollen and pollen tubes; the interactions between pollen and pistil; and pollen size and incompatibility in Nicotiana. This text will be a valuable resource for plant physiologists.

DOWNLOAD EBOOK →The subject of this volume is the reproductive biology of plants. A steadily growing interest in this field is the result of at least two factors, as pointed out with great foresight by one of the driving forces in the field, H.E Linskens (Linskens 1964): most of the food consumed by humans takes the form of plant reproductive parts, and molecular biology now provides pow erful tools for investigating and manipulating plant reproductive systems. Molecular biology and the allied discipline of biotechnology are solidly represented in the papers in this book. The editors of Angiosperm Pollen and Ovules believe that the chapters herein contain some of the most excit ing findings of contemporary biology, and hope that the readers of this book will share their enthusiasm. The editors express sincere and grateful thanks for help from Carla Frova, Enrico Pe, and especially to Giorgio Binelli, all of the University of Milan. Without these three tireless and enthusiastic individuals it would not have been possible to maintain the apparently effortless proceeding of this congress. We thank also the organizing committee and the organizations that generously provided financial support (both listed below). Finally, we extend thanks to M. Cresti, D. Charlesworth, D. Hess, E Hoekstra, R. Bruce Knox, J.P. Mascarenhas, M.E. Nasrallah, P.L. Pfahler, A. Snow, and M.T.M. Willemse for chairing sessions.

DOWNLOAD EBOOK →Concepts of Biology is designed for the single-semester introduction to biology course for non-science majors, which for many students is their only college-level science course. As such, this course represents an important opportunity for students to develop the necessary knowledge, tools, and skills to make informed decisions as they continue with their lives. Rather than being mired down with facts and vocabulary, the typical non-science major student needs information presented in a way that is easy to read and understand. Even more importantly, the content should be meaningful. Students do much better when they understand why biology is relevant to their everyday lives. For these reasons, Concepts of Biology is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand.We also strive to show the interconnectedness of topics within this extremely broad discipline. In order to meet the needs of today's instructors and students, we maintain the overall organization and coverage found in most syllabi for this course. A strength of Concepts of Biology is that instructors can customize the book, adapting it to the approach that works best in their classroom. Concepts of Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand--and apply--key concepts.

DOWNLOAD EBOOK →Palynology, the science of fossil and recent spores/pollen grains, is of high importance, both in many pure and applied fields of the natural sciences (e.g. in botany, geology, climatology, archeology and medicine). It is not only an auxiliary science, but can certainly stand for itself. The "classical" palynology subjects, pollen morphology and systematics, are at present influenced by many modern approaches, e.g. from cell biology, analytical electron microscopy, morphometry, up to com- puter-aided-design of threedimensional reconstruction. In recent years fascinating informations have come to light, and new insights have given rise to changing scientific concepts. During the XIV International Botanical Congress, held in Berlin in 1987, a symposium was devoted to important topics of (actuo)palynology. Nine of its innovative, major contributions are presented in this volume. They cover the comparative morphology and the systematic/evolutionary significance of pollen/spores in critical taxa, aspects of pollen development (cytoskeleton), the substructure of sporopollenin, homologies between wall strata of ferns, gymnosperms and angiosperms, and important (but so far underrated) physical aspects of harmomegathy and pollen transport (fluid versus solid mechanics).

DOWNLOAD EBOOK →Plant Hormones: Biosynthesis and Mechanisms of Action is based on research funded by the Chinese government’s National Natural Science Foundation of China (NSFC). This book brings a fresh understanding of hormone biology, particularly molecular mechanisms driving plant hormone actions. With growing understanding of hormone biology comes new outlooks on how mankind values and utilizes the built-in potential of plants for improvement of crops in an environmentally friendly and sustainable manner. This book is a comprehensive description of all major plant hormones: how they are synthesized and catabolized; how they are perceived by plant cells; how they trigger signal transduction; how they regulate gene expression; how they regulate plant growth, development and defense responses; and how we measure plant hormones. This is an exciting time for researchers interested in plant hormones. Plants rely on a diverse set of small molecule hormones to regulate every aspect of their biological processes including development, growth, and adaptation. Since the discovery of the first plant hormone auxin, hormones have always been the frontiers of plant biology. Although the physiological functions of most plant hormones have been studied for decades, the last 15 to 20 years have seen a dramatic progress in our understanding of the molecular mechanisms of hormone actions. The publication of the whole genome sequences of the model systems of Arabidopsis and rice, together with the advent of multidisciplinary approaches has opened the door to successful experimentation on plant hormone actions. Offers a comprehensive description of all major plant hormones including the recently discovered strigolactones and several peptide hormones Contains a chapter describing how plant hormones regulate stem cells Offers a fresh understanding of hormone biology, particularly molecular mechanisms driving plant hormone actions Discusses the built-in potential of plants for improvement of crops in an environmentally friendly and sustainable manner

DOWNLOAD EBOOK →This Fourth Edition of Principles of Seed Science and Technology, like the fIrst three editions, is written for the advanced undergraduate student or lay person who desires an introduction to the science and technology of seeds. The fIrst nine chapters present the seed as a biological system and cover its origin, development, composition, function (and sometimes nonfunction), performance and ultimate deterioration. The last nine chapters present the fundamentals of how seeds are produced, conditioned, evaluated and distributed in our modern agricultural society. Two new chapters have been added in this fourth edition, one on seed ecology and the second on seed drying. Finally, revisions have been made throughout to reflect changes that have occurred in the seed industry since publication of the Third Edition. Because of the fundamental importance of seeds to both agriculture and to all of society, we have taken great care to present the science and technology of seeds with the respect and feeling this study deserves. We hope that this feeling will be communicated to our readers. Furthermore, we have attempted to present information in a straight-forward, easy-ta-read manner that will be easily understood by students and lay persons alike. Special care has been taken to address both current state-of-the-art as well as future trends in seed technology.
