Sexuality in Plants and Its Hormonal Regulation by M. Kh. Chailakhyan,V.N. Khrianin Pdf

Here is the first book to treat the control of sexuality in plants. The authors provide a thorough review of the literature and discuss many new findings from their laboratory. They include a review of the evolution and genetics of sexuality, including new data on the effect of primary environmental factors on sex expression and the influence of phytohormones on the expression of sexuality as a function of age. The work discussed here has significant implications for plant breeding. Agronomists, horticulturists, and plant physiologists will find practical information on procedures to use in the field or the green house, as well as a thorough introduction to the principles of flowering and fruiting.

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.

Plant Cell Biology by William V Dashek Pdf

While there are a few plant cell biology books that are currently available, these are expensive, methods-oriented monographs. The present volume is a textbook for upper undergraduate and beginning graduate students. This textbook stresses concepts and is inquiry-oriented. To this end, there is extensive use of original research literature. As we live in an era of literature explosion, one must be selective. These judgements will naturally vary with each investigator. Input was sought from colleagues in deciding the literature to include. In addition to provision of select research literature, this volume presents citations and summaries of certain laboratory methods. In this connection, the textbook stresses quantitative data to enhance the student?s analytical abilities. Thus the volume contains computer-spread sheets and references to statistical packages, e.g. Harvard Graphics and Statistica.

Hormonal Regulation of Development III by Richard P. Pharis,David M. Reid Pdf

R. P. PHARIS and D. M. REID The idea of a separate Encydopedia volume dealing with the "interrelations of plant hormones with factors in the environment of the plant, and its organs and tissues" originated with N. P. KEFFORD, and we are most appreciative of the help and advice provided by Prof. KEFFORD in the formative stages of this volume. We have thus interpreted "environment" very broadly to indude not only factors external to the plant, e. g. , gravity, light, temperature, wind, mechanieal wounding, water, organism s (induding pollen), and magnetic and electric stimuli, but internaI factors as well (e. g. , nutrients, both inorganic and photoassimilate, direction, and time). In our definition of "hormonaI effect", or "hormonaI involvement", we have asked our authors to take a broad ap proach, and to examine not only phenomena that are mediated by the known plant hormones, but to discuss as well a wide variety of processes and events where hormonal involvement is implied through more indirect analyses and observations. The volume begins with environmental factors internaI to the plant; R. J. WEAVER and J. O. JOHNSON thus examine "hormones and nutrients", their inter relationship in movement, accumulation, and diversion. As one studies a plant during its rapid growth phase, and later as maturation and aging proceed, it becomes apparent that time is an environmental cue of great significance, one which may exert a major influence via hormonal messages.

Hormonal Regulation of Plant Growth and Development by S.S. Purohit Pdf

The dynamic role of plant hormones in regulation of plant growth and development revealed by its control of rates of metabolic processes and various related enzymetic reactions at molecular and submolecular levels is now weil established. During the course of last 35 years endless development in agricultural biotechnology has provided immense literature to understand hormone-regulated aspects of plant growth and development ; but plant physiologists all over the world are still devoting themselves and will continue for an indifinite period to disclose the mystries of this regulation. Volume I of this series has already been published and has been accepted weil. This encouraged me to edit aseries of volumes (I do not know the number) on this subject. In the following pages various aspects of hormone-controlled physiological processes Iike, Hormonal Control of pro tein synthesis in plants, Auxin-induced elongation, Hormonal regulation of abnormal growth in plants, Hormonal regulation of development in mosses, Some phenolics as plant growth and morphogenesis regulators, Plant growth regulating properties of sterol inhibiting fungicides, Hormonal regulation of sex expression in plants, Water relation and plant growth regulators, Hormonal regulation of root development under water stress, Gravity perception and responses meehanism in graviresponding cereal grass shoots, Hormonal regulation of leaf Growth senescence in relation to stomatal movement, and Chloroindole auxins of pea and related species, have been included.

Plant Hormones by Gerald Litwack Pdf

Volume 72 is wholly dedicated to the topic of plant hormones. Although Vitamins and Hormones is normally dedicated to mammalian hormone action, this volume is unique to plants and their actions through receptors. The genetic aspects and the receptorology are reminiscent of the mammlian systems. The well-known hormones are reviewed including cytokinins, abscicic acid, gibberellin and auxin. In addition there are reviews on nitric oxide, brassinosteroids, jasmonate, ethylene, and pheromones. Other topics included are genes that are regulated by abscicic acid and gibberellin, functional differentiation and transition of peroxisomes, plant antioxidants, gravitropic bending and the actions of plant hormones on glutathione transferase. *Includes color illustrations *Available on ScienceDirect *Longest running series published by Academic Press *Contributions by leading international authorities

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.

Growth, Differentiation and Sexuality by Friedhelm Meinhardt,Joseph G.H. Wessels Pdf

Mycology, the study of fungi, originated as a subdiscipline of botany and was a descriptive discipline, largely neglected as an experimental science until the early years of this century. A seminal paper by Blakeslee in 1904 provided evidence for self-incompatibility, termed "heterothallism", and stimulated interest in studies related to the control of sexual reproduction in fungi by mating-type specificities. Soon to follow was the demonstration that sexually reproducing fungi exhibit Mendelian inheritance and that it was possible to conduct formal genetic analysis with fungi. The names Burgeff, Kniep and Lindegren are all associated with this early period of fungal genetics research. These studies and the discovery of penicillin by Fleming, who shared a Nobel Prize in 1945, provided further impetus for experimental research with fungi. Thus began a period of interest in mutation induction and analysis of mutants for bio chemical traits. Such fundamental research, conducted largely with Neurospora crassa, led to the one gene: one enzyme hypothesis and to a second Nobel Prize for fungal research awarded to Beadle and Tatum in 1958. Fundamental research in biochemical genetics was extended to other fungi, especially to Saccharomyces cerevisiae, and by the mid-1960s fungal systems were much favored for studies in eukaryotic molecular biology and were soon able to compete with bacterial systems in the molecular arena.

Concepts of Biology by Samantha Fowler,Rebecca Roush,James Wise Pdf

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.

Hormonally Active Agents in the Environment by National Research Council,Commission on Life Sciences,Board on Environmental Studies and Toxicology,Committee on Hormonally Active Agents in the Environment Pdf

Some investigators have hypothesized that estrogens and other hormonally active agents found in the environment might be involved in breast cancer increases and sperm count declines in humans as well as deformities and reproductive problems seen in wildlife. This book looks in detail at the science behind the ominous prospect of "estrogen mimics" threatening health and well-being, from the level of ecosystems and populations to individual people and animals. The committee identifies research needs and offers specific recommendations to decision-makers. This authoritative volume: Critically evaluates the literature on hormonally active agents in the environment and identifies known and suspected toxicologic mechanisms and effects of fish, wildlife, and humans. Examines whether and how exposure to hormonally active agents occursâ€"in diet, in pharmaceuticals, from industrial releases into the environmentâ€"and why the debate centers on estrogens. Identifies significant uncertainties, limitations of knowledge, and weaknesses in the scientific literature. The book presents a wealth of information and investigates a wide range of examples across the spectrum of life that might be related to these agents.

Plant Physiology 7A by F.C. Steward Pdf

Plant Physiology: A Treatise, Volume VIA: Physiology of Development: Plants and Their Reproduction explores the various problems of development and reproduction that arise as plants, responsive to environmental stimuli, develop a vegetative plant body and produce seeds and fruits or organs of perennation. This book considers the morphological aspects of plant growth and development as well as the growth and reproduction of fungi, physiological aspects of vegetative reproduction and flowering, and perennation and dormancy. This volume is organized into four chapters and begins with an overview of growth and development, with reference to organization and patterns of development in vascular plants and the initiation and development of plants. The discussion then shifts to vegetative, sexual, and asexual reproduction in fungi, along with heterokaryosis and morphogenesis. The next chapter explores reproduction in plant biology, focusing on vegetative and sexual reproduction, sex determination, and photoperiodism. This book concludes by considering the physiological mechanisms underlying the production of organs of perennation and the establishment of dormancy. This text will be of value both to graduate students and to established investigators with specific interest in plant physiology.
