Plant molecular biology has produced an ever-increasing flood of data about genes and genomes. Evolutionary biology and systematics provides the context for synthesizing this information. This book brings together contributions from evolutionary biologists, systematists, developmental geneticists, biochemists, and others working on diverse aspects of plant biology whose work touches to varying degrees on plant molecular evolution. The book is organized in three parts, the first of which introduces broad topics in evolutionary biology and summarizes advances in plant molecular phylogenetics, with emphasis on model plant systems. The second segment presents a series of case studies of gene family evolution, while the third gives overviews of the evolution of important plant processes such as disease resistance, nodulation, hybridization, transposable elements and genome evolution, and polyploidy.
Plant neurobiology is a newly emerging field of plant sciences. It covers signalling and communication at all levels of biological organization from molecules up to ecological communities. In this book, plants are presented as intelligent and social organisms with complex forms of communication and information processing. Authors from diverse backgrounds such as molecular and cellular biology, electrophysiology, as well as ecology treat the most important aspects of plant communication, including the plant immune system, abilities of plants to recognize self, signal transduction, receptors, plant neurotransmitters and plant neurophysiology. Further, plants are able to recognize the identity of herbivores and organize the defence responses accordingly. The similarities in animal and plant neuronal/immune systems are discussed too. All these hidden aspects of plant life and behaviour will stimulate further intense investigations in order to understand the communicative plants in their whole complexity. "
The fundamental problem the world faces today, is the rapidly increasing pressure of population on the limited resources of the land. To meet the ever increasing demands of expanding populations, agricultural production has been raised through the abundant use of inorganic fertilizers, the adoption of multicropping systems and liberal application of chemical pesticides (fungicides, bactericides, etc. ). Though the use of chemicals has increased the yield dramatically, it has also resulted in the rapid deterioration of land and water resources apart from wastage of scarce resources. This has adversely affected the biological balance and lead to the presence of toxic residues in food, soil and water in addition to imposing economic constraints on developing countries.' (From the Preface) Mycorrhizal Biology addresses the global problem of land degradation and the associated loss of soil productivity and decline in soil quality caused by exploitative farming practices and poor management in developing countries, and the far reaching socio-economic and ecological consequences of its impact on agricultural productivity and the environment. In the light of a need for sustainable development, a new system of productive agriculture, to ensure the efficient management of agricultural inputs for long term high crop productivity with minimum damage to the ecological and socio-economic environment is essential. The management of mycorrhizal fungi will form a significant part of such a system and this work investigates the key association of plant roots with mycorrhizal fungi, known to benefit plants under conditions of nutritional and water stress and pathogen challenge and analyses thedevelopments in our understanding of the genetic loci that govern mycorrhiza formation.
Plant tissue culture and advanced biotechnologies have proven to be influential tools that complement conventional breeding and accelerate development of many medicinal plants. Various approaches, such as pathway engineering, precursor feeding, transformation, elicitation with biotic and abiotic elicitors and scaling up in bioreactors, have been explored to improve the production of secondary metabolites from different medicinal plants. This book provides a comprehensive description of various studies, carried out on in vitro culture and hairy root cultures of Catharanthus roseus, Silybum marianum and Digitalis species which have been considered as alternative sources for the production of anti-tumour compounds, flavonolignans and cardenolides. Specific focus is on elicitation strategy for increasing production of bioactive compounds of C. roseus L., S. marianum and Digitalis species to overcome the constrains of conventional propagation. This book is valuable for researchers or students working on medicinal plants, phytochemistry, and plant tissue culture. It also serves as a reference for the pharmaceutical industry.
With one volume each year, this series keeps scientists and advanced students informed of the latest developments and results in all areas of the plant sciences. The present volume includes reviews on genetics, cell biology, physiology, comparative morphology, systematics, ecology, and vegetation science.
Originally published in 1913, the aim is to illustrate and describe every species, from the fern upwards, recognised as distinct by botanists and growing wild within the area adopted, and to complete the work within such moderate limits of size and cost as shall make it accessible to the public generally, so that it may serve as an independent handbook of our Northern Flora and as a work of general reference. This is a fascinating read for any botanist with much of the information still practical and useful today. Many of the earliest books, particularly those dating back to the 1900's and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
This new book shows the work done by researchers dedicated to the study of different mycorrhizas types, the fungal species associated and their distribution influenced by geographical and environmental factors among the different South American biogeographic regions. The exclusive biotic and abiotic characteristics delimit natural ecosystems with uniques biological communities, where mycorrhizologists have investigated plant symbioses in those ecosystems for decades, providing data from Venezuelan Great Savannah, Andes, Puna, Chaco, Caatinga, Monte, Atlantic Forest, Marginal Forest, Cerrado, Patagonia, Yungas, Rainforest, Andean-Patagonian Forests, and Antarctic section. In these environments, different mycorrhizal associations (arbuscular / ericoid / orchidoid / ectomycorrhizal / mycoheterotrophic) are present in herbaceous plants, shrubs, and trees. Mycorrhizal associations were studied from different researching points of view (biodiversity, biological invasions, biotic / abiotic disturbances, altitudinal variations, seasonal changes, land uses). The aim of this Book is to compile research on mycorrhizal fungi and their associations in environments of South America, throughout the synthesis of information from natural and anthropogenic related environments. The book focuses in different bioregions of South America from tropical areas to the southern cone, and it will be useful to those who work on plant-fungal interactions in different vegetation types and in agricultural lands from South America and worldwide.
In the course of evolution, a great variety of root systems have learned to overcome the many physical, biochemical and biological problems brought about by soil. This development has made them a fascinating object of scientific study.This volume gives an overview of how roots have adapted to the soil environment and which roles they play in the soil ecosystem. The text describes the form and function of roots, their temporal and spatial distribution, and their turnover rate in various ecosystems. Subsequently, a physiological background is provided for basic functions, such as carbon acquisition, water and solute movement, and for their responses to three major abiotic stresses, i.e. hard soil structure, drought and flooding. The volume concludes with the interactions of roots with other organisms of the complex soil ecosystem, including symbiosis, competition, and the function of roots as a food source.
In 2010 the global area of transgenic crops reached 148 million hectares, an 87-fold increase since 1996, making it the most rapidly adopted technology in the history of modern agriculture. In Transgenic Plants: Methods and Protocols, Second Edition expert researchers in the field provide key techniques to investigate production and analysis of transgenic plants. Focusing on selection and detection methods, transformation technology, gene targeting, silencing and directed mutation, metabolic engineering and pharming, the book encompasses protocols relating to major crops and model plants being used for genomic analysis. Written in the highly successful Methods in Molecular Biology (TM) series format, the chapters include the kind of detailed description and implementation advice that is crucial for getting optimal results in the laboratory. Thorough and intuitive, Transgenic Plants: Methods and Protocols, Second Edition aids scientists in the continuous improvements being made for the production and analysis of transgenic plants.
From this modern and profusely illustrated book, the reader will learn not just the basics, which are amply reviewed, but also how plant anatomy is integrated with a wide variety of other disciplines, such as plant breeding, forensic analysis, medicine, food science, wood and fiber products, and the arts. The author presents the basic concepts and terminology of plant anatomy with a special emphasis on its significance and applications to other disciplines, and addresses the central role of anatomy by consolidating previously scattered information into a single volume. Integrative Plant Anatomy highlights the important contribution made by studying anatomy to the solutions of a number of present and future problems. It succeeds in integrating diverse areas of botany, as well as the non-biological sciences, the arts, and numerous other fields of human endeavor. * Presents both the classical and modern approaches to the
subject
Mycorrhizal fungi are microbial engines which improve plant vigor and soil quality. They play a crucial role in plant nutrient uptake, water relations, ecosystem establishment, plant diversity, and the productivity of plants. Scientific research involves multidisciplinary approaches to understand the adaptation of mycorrhizae to the rhizosphere, mechanism of root colonization, effect on plant physiology and growth, biofertilization, plant resistance and biocontrol of plant pathogens. This book discusses and goes into detail on a number of topics: the molecular basis of nutrient exchange between arbuscular mycorrhizal (AM) fungi and host plants; the role of AM fungi in disease protection, alleviation of soil stresses and increasing grain production; interactions of AM fungi and beneficial saprophytic mycoflora in terms of plant growth promotion; the role of AM fungi in the restoration of native ecosystems; indirect contributions of AM fungi and soil aggregation to plant growth and mycorrhizosphere effect of multitrophic interaction; the mechanisms by which mycorrhizas change a disturbed ecosystem into productive land; the importance of reinstallation of mycorrhizal systems in the rhizosphere is emphasized and their impact on landscape regeneration, and in bioremediation of contaminated soils; Ectomycorrhizae (ECM) and their importance in forest ecosystems and associations of ECM in tropical rain forests function to maintain tropical monodominance; in vitro mycorrhization of micro-propagated plants, and visualizing and quantifying endorhizal fungi; the use of mycorrhizae, mainly AM and ECM, for sustainable agriculture and forestry.
A practical guide to the protection and management of ecosystems against invasions by non-indigenous plant species. The authors seek to offer an accessible account of the subject and how to protect natural habitats. The majority of countries suffer from invasive plants and there are case studies from North America, Europe, Australia, South and South East Asia and the Pacific and Atlantic islands. There is also a list of invasive species, with their countries of origin and regions of introduction.
Health care delivery has become institutionalized. As a result,
health care organizations now have the power to determine who has
access to what kind of health care and under what circumstances.
They shape as well the ethics of the various health care
professions. These developments have provoked controversies about
what kind of obligations such health care organizations have to
patients, caregivers, and society at large. In order to respond to
these controversies, an account of health care organizational
ethics has become necessary. -are drawn from an interdisciplinary group of leading scholars in this growing field; -address the nature of health care organizational ethics, including such issues as corporate fraud and institutional moral integrity; -cover the broad range of issues that must be addressed for a coherent discussion of organizational moral responsibility; -cover the range of theoretical and practical issues like no other volume; -are of interest to researchers, students and professionals working in the fields of bioethics, health care administration and management, organizational science, and business ethics.
Written by the leading experts in the field, this book examines the evolutionary advantages of gender dimorphism - the occurence of two sexual forms - and sexual dimorphism - dimorphism in secondary sex characters - in flowering plants. Gender dimorphism is found in approximately 10% of flowering plant species and has been an active topic of research. By contrast, sexual dimorphism in plants is much less widely appreciated. The book consists of three sections: The first introduces readers to the tremendous variety of breeding systems and their evolution in plants and sets the stage for a consideration of the evolution of dimorphism in reproductive and non-reproductive characters. The second section deals with the evolution of secondary sexual characters, including the theory related to the evolution of sexual dimorphism and its empirical patterns. The last section deals with the genetics of gender expression and of secondary sexual characters.
Since the concept of allelopathy was introduced almost 100 years ago, research has led to an understanding that plants are involved in complex communicative interactions. They use a battery of different signals that convey plant-relevant information within plant individuals as well as between plants of the same species or different species. The 13 chapters of this volume discuss all these topics from an ecological perspective. Communication between plants allows them to share physiological and ecological information relevant for their survival and ?tness. It is obvious that in these very early days of ecological plant communication research we are illuminating only the 'tip of iceberg' of the communicative nature of higher plants. Nevertheless, knowledge on the identity and informative value of volatiles used by plants for communication is increasing with breath-taking speed. Among the most spectacular examples are sit- tions where plant emitters warn neighbours about a danger, increasing their innate immunity, or when herbivore-attacked plants attract the enemies of the herbivores ('cry for help' and 'plant bodyguards' concepts). It is becoming obvious that plants use not only volatile signals but also diverse water soluble molecules, in the case of plant roots, to safeguard their evolutionary success and accomplish self/non-self kin rec- nition. Importantly, as with all the examples of biocommunication, irrespective of whether signals and signs are transmitted via physical or chemical pathways, plant communication is a rule-governed and sign-mediated process.

Humans face the challenge of producing enough food to meet the
demands imposed by economic, biological and agricultural factors:
rising population; rising income; and an expectation of higher
quality food and a more diverse diet; decreasing amount of land
available for food production; lowering environmental impact of
agricultural practices and preserving biodiversity.
As a member of the working group (WG) on "Temperate Zone Fruit Trees in the Tropics and Subtropics" of the International Society for Horticulture, I was aware of the lack of readily available information needed in many warm-climate locations where temperate fruit crops are grown. The founder of this WG, Frank Dennis, Jr. , was motivated to encourage knowledge transfer by sharing knowledge with many developing countries. We shared his drive and in presenting this book we believe we are doing a service to all persons interested in temperate fruits, but especially to those in tropical and subtropical countries, many of which are developing countries interested in growing these crops and lacking the knowledge needed. In this book, we have collected information covering a variety of different aspects of growing temperate fruit crops in warm climates. As this is the first time such an evaluation of these species has been done, interesting and novel aspects of tree development and fruiting are presented, with stress on elements like dormancy and irrigation that are not of such basic concern in the natural of the temperate zones. We are living in a transition age; horticultural studies habitat are changing and expertise such as can be found in the array of participants in this book is probably not going to be easily found in the future. I hope that this book will broaden our understanding of the fruiting Temperate Zone tree in general and of its adaptation to warm climates, in particular.
th We compiled this volume mostly from presentations at the 6 International Plant Cold Hardiness Seminar (PCHS) after consulting with Professor Tony H. H. Chen, Oregon State University, USA, Professor Pekka Heino, University of Helsinki, Finland, th and Dr. Gareth J. Warren, University of London, Surrey, UK. The 6 International PCHS was held at the Unitas Congress Center, Helsinki, Finland from July 1-5, 2001. There were 110 registered scientists at the serttinar representing 20 countries: Australia, Belgium, Canada, Chile, the Czech Republic, Denmark, Estonia, Finland, Gennany, Hungary, Iceland, Italy, Japan, Norway, Poland, Spain, Sweden, Taiwan, United Kingdom, and United States of America. The infonnation compiled represents the state of the art of research in phmt cold hardiness in tenns of gene regulation, gene expression, signal transduction, the physiology of cold hardiness and, ultimately, the genetic engineering for cold tolerant plants. The International PCHS was initiated in 1977 at the University of Minnesota, St. Paul, Minnesota. It has been traditionally held at 5-year intervals at various locations. th Because of the rapid advances of research in plant cold hardiness, attendees at the 6 meeting unanimously adopted a resolution to hold the seminar in 3-year intervals instead of 5 in the future. Consequently, the next seminar will be held in 2004 in Sapporo, Japan, and Professor Seizo Fujikawa from Hokkaido University will serve as the host.
In the 1970s, Rolla and Alice Tryon of Harvard organized an annual fern conference at Harvard Forest every spring. The mission of the conference was to bring together researchers from across a broad spectrum of biology whose common link was that they either studied ferns per se or utilized ferns in their experiments. Talks ranged from classical pteridological subjects such as taxonomy, paleobotany and morp- logy, to experimental areas such as ecology, physiology, development, genetics, and biochemistry. For the participants, of whom I was lucky to be one, it was an int- lectually exhilarating experience. We all learned new things, and the cross fertili- tion of different subjects and research approaches led to new ideas and a better understanding of ferns as organisms. The present volume, Working with Ferns: Issues and Applications, edited by Helena Fernandez, Ashwani Kumar and Maria Angeles Revilla, carries the Harvard Forest Fern Conference philosophy into the twenty-first century. The editors have assembled a truly remarkable array of contributions dealing with fern biology. Starting with researches utilizing Ceratopteris, a fern whose speedy life cycle I discovered during my doctoral research at the Royal Botanic Gardens, Kew more than 40 years ago, and ending with a study of Pteridium aq- linum, a cosmopolitan species taxonomically revised by Professor Rolla Tryon, the papers in Working with Ferns: Issues and Applications offer a look at what is new in pteridology.
Photosynthetic Adaptation: Chloroplast to Landscape thoroughly studies photosynthetic mechanisms at each structural level, from cells to leaves, crown, and canopy. The authors question whether photosynthetic adaptations take place primarily at the metabolic and biochemical level or through changes in structure and form, or both. In the interest of genetic engineering and agricultural applications, the authors analyze the relative importance of genes that control both metabolic and light reactions as well as the structure, arrangement, and orientation of photosynthesis.
