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

Download or read book Chemical Synthesis of Hormones Pheromones and Other Bioregulators written by Kenji Mori and published by John Wiley & Sons. This book was released on 2011-02-25 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many small molecules occur naturally as "messenger" chemicals which regulate the behaviour and functions of microbes, plants, insects and animals. Examples include hormones, pheromones, phytoalexins, and antifeedants. These biofunctional molecules are of great interest to researchers in helping develop our understanding of biological function and in the development of new drugs. However extracting them from nature can be prohibitively expensive, so there is great interest in devising methods of synthesising them from simple starting materials in the laboratory. Chemical Synthesis of Hormones, Pheromones and Other Bioregulators is an introduction to the techniques and strategies for the synthesis of biofunctional small molecules. Topics include: what are biofunctional molecules? why must biofunctional molecules be synthesized? how can we synthesize biofunctional molecules? the synthesis of phytohormones, phytoalexins and other biofunctional molecules of plant origin the synthesis of insect juvenile hormones and antifeedants the synthesis of pheromones and the significance of chirality in pheromone science the synthesis of microbial hormones and pheromones, antibiotics, and other biofunctional molecules of microbial origin the synthesis of marine antifeedants and medicinal candidates a synthetic examination of incorrectly proposed structures of biomolecules reflections on science as a human endeavor Drawing on a career of almost 50 years researching and teaching this subject, Kenji Mori's Chemical Synthesis of Hormones, Pheromones and Other Bioregulators is a must-have textbook for students and researchers of organic synthesis and natural products, and a stimulating and inspiring account of a distinguished chemical career.

Download or read book Phytochemical Diversity and Redundancy in Ecological Interactions written by John T. Romeo and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diversity within and among living organisms is both a biological impera tive and a biological conundrum. Phenotypic and genotypic diversity is the critical currency ofecological interactions and the evolution of life. Thus, it is not unexpected to find vast phytochemical diversity among plants. However, among the most compelling questions which arise among those interested in ecological phytochemistry is the extent, nature, and reasons for the diversity of chemieals in plants. The idea that natural products (secondary metabolites) are accidents of metabolism and have no biological function is an old one which has resurfaced recently under a new term "redundancy. " Redundancy in the broader sense can be viewed as duplication of effort. The co-occurrence of several classes of phytochemieals in a given plant may be redundancy. Is there unnecessary duplication of chemical defense systems and ifso, why? What selective forces have produced this result? On the other hand, why does the same compound often have multiple functions? At a symposium of the Phytochemical Society of North America held in August 1995, in Sault Ste. Marie, Ontario, Canada, the topic "Phytochernical Redundancy in Ecological Interactions" was discussed. The chapters in this volume are based on that symposium. They both stimulate thought and provide some working hypotheses for future research. It is being increasingly recognized that functional diversity and multiplicity of function of natural products is the norm rather than the exception.
