Book Synopsis Pollination in Plants by : Phatlane William Mokwala
Download or read book Pollination in Plants written by Phatlane William Mokwala and published by BoD – Books on Demand. This book was released on 2018-06-06 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants are the basic source of food for both humans and animals. Most of the food is made of fruits and seeds. For these to be formed, pollination must first take place. This process is the transfer of pollen grains from the anther, which is the male structure of the flower, to the sigma on the female structure of the flower. The transfer process requires agents to be carried out. The agents can be either biotic or abiotic. Nature perfected this arrangement between the pollination agents and the plants. As ecosystems and agricultural systems are changing, this balanced arrangement becomes disturbed. This makes it necessary that pollination systems be studied so that necessary measures can be undertaken to ensure productivity. The chapters of this book present results in research undertaken to improve productivity in crops such as Actinidia chinensis (the kiwifruit), Theobroma cacao (cocoa), and Manicaria saccifera (a tropical forest palm). Some results are presented on tests to check the viability of pollen grains and the delivery of sperm cells through pollen tubes to the embryo sac. These results can serve as guidelines to any person seeking to improve pollination and productivity or to check the efficiency on pollination in ecosystems or agricultural production systems.
Book Synopsis Angiosperm Pollen and Ovules by : E. Ottaviano
Download or read book Angiosperm Pollen and Ovules written by E. Ottaviano and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Hormone Metabolism and Signaling in Plants by : Jiayang Li
Download or read book Hormone Metabolism and Signaling in Plants written by Jiayang Li and published by Academic Press. This book was released on 2017-04-19 with total page 616 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Book Synopsis Sexual Reproduction in Animals and Plants by : Hitoshi Sawada
Download or read book Sexual Reproduction in Animals and Plants written by Hitoshi Sawada and published by Springer. This book was released on 2014-02-07 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of the International Symposium on the Mechanisms of Sexual Reproduction in Animals and Plants, where many plant and animal reproductive biologists gathered to discuss their recent progress in investigating the shared mechanisms and factors involved in sexual reproduction. This now is the first book that reviews recent progress in almost all fields of plant and animal fertilization. It was recently reported that the self-sterile mechanism of a hermaphroditic marine invertebrate (ascidian) is very similar to the self-incompatibility system in flowering plants. It was also found that a male factor expressed in the sperm cells of flowering plants is involved in gamete fusion not only of plants but also of animals and parasites. These discoveries have led to the consideration that the core mechanisms or factors involved in sexual reproduction may be shared by animals, plants and unicellular organisms. This valuable book is highly useful for reproductive biologists as well as for biological scientists outside this field in understanding the current progress of reproductive biology.

Book Synopsis Endocytosis in Plants by : Jozef Šamaj
Download or read book Endocytosis in Plants written by Jozef Šamaj and published by Springer Science & Business Media. This book was released on 2012-10-02 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Endocytosis is a fundamental cellular process by means of which cells internalize extracellular and plasma membrane cargos for recycling or degradation. It is important for the establishment and maintenance of cell polarity, subcellular signaling and uptake of nutrients into specialized cells, but also for plant cell interactions with pathogenic and symbiotic microbes. Endocytosis starts by vesicle formation at the plasma membrane and progresses through early and late endosomal compartments. In these endosomes cargo is sorted and it is either recycled back to the plasma membrane, or degraded in the lytic vacuole. This book presents an overview of our current knowledge of endocytosis in plants with a main focus on the key molecules undergoing and regulating endocytosis. It also provides up to date methodological approaches as well as principles of protein, structural lipid, sugar and microbe internalization in plant cells. The individual chapters describe clathrin-mediated and fluid-phase endocytosis, as well as flotillin-mediated endocytosis and internalization of microbes. The book was written for a broad spectrum of readers including students, teachers and researchers.

Book Synopsis Incompatibility in Angiosperms by : D. de Nettancourt
Download or read book Incompatibility in Angiosperms written by D. de Nettancourt and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: Attempting to collect, sort out, comment on and summarize from available literature the relevant information dealing with a specific problem is always a difficult task which necessarily involves sub jective choices and implies a considerable risk of errors and omis sions. The difficulty is increased when, as in the case of incompati bility in angiosperms, the subject to be treated traces its history to preDarwinian times and reflects the total sum of numerous in vestigations dealing with widely different disciplines, such as ge netics, cytology, biochemistry, systematics and physiology, which no single reviewer may pretend to master sufficiently to avoid completely the possibility of misinterpretation. Furthermore, the complexity of the task is further augmented by the fact that the student of incompatibility, confronted as he or she is with still poorly understood phenomena of genetic control and molecular recognition, often tends to be speculative and, in some instances, over-imaginative at the time of fitting research observations and experimental data into appropriate models, schemes and hypo theses. The compensation for such a state of affair is, however, a strong one and lies in the remarkable willingness and readiness of "in compatibilists" to cooperate, and to provide information, ex planations and illustrations to anyone attempting to penetrate into their universe of research and of reflection.
Book Synopsis Biostimulants for Crops from Seed Germination to Plant Development by : Shubhpriya Gupta
Download or read book Biostimulants for Crops from Seed Germination to Plant Development written by Shubhpriya Gupta and published by Academic Press. This book was released on 2021-06-23 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biostimulants for crops from seed germination to plant development focuses on the effects and roles of natural biostimulants in every aspect of plant growth development to reduce the use of harmful chemical fertilizers and pesticides. Biostimulants are a group of substances of natural origin that offer a potential to reduce the dependency on harmful chemical fertilizers causing environmental degradation. While there is extensive literature on biostimulants, there remains a gap in understanding how natural biostimulants work and their practical application. This book fills that gap, presenting the ways in which biostimulants enhance seed vigor and plant productivity by looking into their mode of action, an area still being researched for deeper understanding. Exploring the roles of seed germination, pollen tube formation, pollen-pistil interaction, flower and fruit setting, to plant pigments, rhizospheric and soil microorganisms, the book also sheds light on the challenges and realistic opportunities for the use of natural biostimulants. Approaches biostimulant research with the goal of transforming scientific research into practical application Includes real-world examples from laboratory, greenhouse and field experiments Presents the biochemical, physiological and molecular mode of action of biostimulants
