Cytokinins by David W. S. Mok Pdf

Cytokinins are hormones involved in all aspects of plant growth and development and are essential for in vitro manipulation of plant cells and tissues. Much information has been gathered regarding the chemistry and biology of cytokinins, while recent studies have focused on the genetics and cytokinin-related genes. However, other than proceedings of symposia, no single volume on cytokinins has been written. This book is the first of its kind, homing in on the key subject areas of cytokinin-chemistry, biosynthesis, metabolism, activity, function, genetics, and analyses. These areas are comprehensively reviewed in individual chapters by experts currently active in the field. In addition, a personal history on the discovery of cytokinin is presented by Professor Folke Skoog. This volume summarizes previous findings and identifies future research directions.

Metabolism and Molecular Activities of Cytokinins by J. Guern,C. Peaud-Lenoel Pdf

In a number of recent biology meetings, plant growth factors have been a favorite topic. One may ask if a new colloquium devoted to the metab olism and the activities of cytokinins, considered at the molecular level, was really necessary and will add anything important to the previous contributions. As a matter of fact, the primary purpose of the organizers, of the French National Center of Scientific Research, and of the National In stitute of Agronomic Research which sponsored the colloquium was less the edition of a proceedings book than the desire to bring together a number of scientists who had made contributions towards solving prob· lems in cytokinin research and thereby to provide an opportunity for fruitful discussions without restrictions in the timetable. Indeed this primary target was attained. Moreover, important new fmdings and con clusions were presented by the participants that merited publication in the form ofthis book. It is beyond the scope of this foreword to adver tize or even to classify these new fmdings. We shall only mention a few of them. The reader will appreciate the contributions of those authors who worked hard to elucidate the biosynthetic pathways of natural cytokin ins.

Auxins, Cytokinins and Gibberellins Signaling in Plants by Tariq Aftab Pdf

Plant hormones have pivotal roles in the regulation of plant growth, development, and reproduction. Their signaling pathways are interconnected in a complex network, which provides plants with an enormous regulatory potential to rapidly adapt to their environment and to utilize their limited resources for growth and survival in a cost-efficient manner. Auxin is a hormone molecule whose activity levels are most important for its regulatory roles during plant cell, organ, and tissue development. Therefore, the precise regulation of auxin levels is an essential mechanism to fine-tune the activity of this powerful hormone during plant growth and development. Likewise, cytokinins exhibit a wide range of physiological functions, including regulation of shoot and root apical meristems, stimulation of branching, vascular development, chloroplast differentiation, stabilization of the structure and function of the photosynthetic machinery, delay of senescence, stomata opening, and elevation of the sink strength and nutritional signaling. Moreover, gibberellins also regulate many aspects of plant growth and development including seed germination, stem elongation, leaf expansion, and flower and fruit development. The broad implication of gibberellins in plant development is strictly associated with tight regulation of their metabolism by multiple environmental and endogenous factors, ranging from light and temperature to other hormones including feedback control. Understanding the significant roles of these phytohormones in plant biology, the current subject has attracted the attention of scientists from across the globe. This comprehensive volume “Auxins, Cytokinins and Gibberellins Signaling in Plants” highlights the various prospects involved in the current scenario. The book comprises the chapters from diverse areas dealing with biotechnology, molecular biology, proteomics, genomics, metabolomics, etc.

Cytokinins by Sonja Kortesmaki Pdf

Cytokinins: Biosynthesis and Uses discusses ornamental pot plant productivity, which is negatively affected by the pot root restriction during both the nursery and post-transplant stages. Root restriction is a physical stress imposed on the root system when plants are grown in small containers, which leads to a pronounced decrease in root and shoot growth at both the transplant and pot stages. Next, the authors summarize most information available on the main environmental and hormonal factors that affect New Guinea Impatiens plant growth under commercial conditions and shows the high potentiality of exogenous cytokinin application in both the vegetative propagation industry and pot culture of ornamental plants. The closing chapter addresses how understanding plant responses to hormonal manipulation and the physiological mechanisms involved in transplantation will allow for reaching higher commercial yields in different vegetables.

Phytohormones in Plant Biotechnology and Agriculture by Ivana Machácková,Georgy A. Romanov Pdf

Phytohormone research is a crucially important area of plant sciences. Phytohormones are one of the key systems integrating metabolic and developmental events in the whole plant and the response of plants to external factors. Thus, they influence the yield and quality of crops. During the last decade we have slowly begun to understand the molecular mechanisms underlying phytohormone action, largely as a result of the rapid developments that have been made internationally in the field of plant molecular genetics. Putative receptor proteins for ethylene (1993- 95), brassinosteroids (1997) and cytokinins (2001) have been identified and the genes that encode them cloned. Primary response genes and elements of hormonal signal transduction have also been identified for most known phytohormones. There is now little doubt that phytohormones, like their animal counterparts, function as signal molecules and create a signalling network in the whole plant organism. The in vivo activity of hormones depends, among other things, on their rate of biosynthesis and metabolism, and on their transport into and out of target cells. Consequently, genes and enzymes involved in these processes are of particular interest. In recent years a number of genes encoding enzymes for the synthesis, modification and degradation of different phytohormones have been cloned and identified, as have genes encoding proteins involved in phytohormone transport and its regulation. Some classes of phytohormone have been shown to participate in stress reactions and can increase the resistance of plants to unfavorable environmental factors.

Physiological Responses of Plants to Attack by Dale Walters Pdf

Despite the research effort put into controlling pathogens, pestsand parasitic plants, crop losses are still a regular feature ofagriculture worldwide. This makes it important to manage the cropappropriately in order to maximise yield. Understanding therelationship between the occurrence and severity of attack, and theresulting yield loss, is an important step towards improved cropprotection. Linked to this, is the need to better understand themechanisms responsible for reductions in growth and yield inaffected crops. Physiological Responses of Plants to Attack is unique because itdeals with the effects of different attackers – pathogens,herbivores, and parasitic plants, on host processes involved ingrowth, reproduction, and yield. Coverage includes effects onphotosynthesis, partitioning of carbohydrates, water and nutrientrelations, and changes in plant growth hormones. Far from beingsimply a consequence of attack, the alterations in primarymetabolism reflect a more dynamic and complex interaction betweenplant and attacker, sometimes involving re-programming of plantmetabolism by the attacker. Physiological Responses of Plants to Attack is written anddesigned for use by senior undergraduates and postgraduatesstudying agricultural sciences, applied entomology, cropprotection, plant pathology and plant sciences. Biological andagricultural research scientists in the agrochemical and cropprotection industries, and in academia, will find much of use inthis book. All libraries in universities and researchestablishments where biological and agricultural sciences arestudied and taught should have copies of this exciting book ontheir shelves

Hormone Metabolism and Signaling in Plants by Jiayang Li,Chuanyou Li,Steven M Smith Pdf

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

Physiological Processes in Plants Under Low Temperature Stress by A. Bhattacharya Pdf

This book is a collection of comprehensive reviewed chapters covering major physiological aspects, both production as well as biochemical aspects, of a plant under low temperature stress. Low temperature stress has been dealt in two parts, first between 10 to 00 C and secondly between 0 to -400 C. This book highlights the physiological aspects of plants under low temperature stress and explains the various adaptive measures plants undergo to tolerate low temperature stress. Essential information is provided on germination, growth and development, dry matter accumulation, partitioning and final yield of a crop plant. As physiology deals with morphological and biochemical aspect of all the basic processes, therefore an in depth understanding the major physiological issues in plants under high temperature will help plant breeders to tailor different crop plants with desirable physiological traits to do better under higher temperature. The present book is intended to cover the effects of low temperature stress on the various physiological aspects in plants. Not only in production physiology, this book also deals with major biochemical processes, like photosynthesis, nitrogen and lipid metabolism, mineral nutrition and plant growth hormones. Efforts have been made deal with different measures to mitigate the effects of low temperature stress on plants. This book will be an asset for post graduate students, faculty members, researchers engaged in not only in physiological studies but also agronomy, plant breeding and like subjects. In depth analysis of the major physiological processes in plants under low temperature stress that are presented in this book will help plant breeders for tailoring crops for desirable physiological traits needed to survive and to give better economic return under the threats of low temperature stress. This book is also helpful for policy planners and industries engaged in agribusiness in short term as well as long term gain.
