Until recently, the production of fruits by plants, their consumption by animals (frugivory) and the relevance of these to seed dispersal have attracted less attention than topics such as pollination biology. However, since the 1970s they have started to gain more prominence and now give rise to more research funding, seminal papers and international symposiums. This book contains chapters adapted from the Third International Symposium-Workshop on Frugivores and Seed Dispersal held in August 2000, in Rio Quente, Brazil.
This successful text examines the ecological processes that determine the size and structure of a population, and demonstrates that there are many fundamental principles that apply to populations of both animals and plants. The authors have sought to involve the text in areas where particular progress has been made and consolidated. The third edition therefore addresses the problem of the detection of chaos, buried sea-banks and herbivorey implants and looks more closely at the role of spatial scale in two-species interactions. It also introduces a major new section on the concept of the meta-population. The book is designed to be readily understood by undergraduates with little or no previous knowledge of the subject, and also to stimulate wider debate and discussion.
Quantitative modeling of Mendelian genetics Quantitative Genetics with Special Reference to Plant and Animal Breeding provides authoritative guidance on improving genetic material in breeding programs through the application of Mendelian genetics. Beginning with a brief background on genetic modeling and breeding programs, the book compares breeding procedures and selection approaches while offering expert guidance on mathematical and Mendelian representation of various schema. Highly detailed and practically-focused with clear guidance on methods and calculations, this guide provides invaluable reference for the design of breeding programs in the laboratory or agricultural industry.
Part of a series which presents papers of topical interest relating to the breeding of plants important to agriculture and horticulture.
Plant Breeding Reviews is an ongoing series presenting state-of-the art review articles on research in plant genetics, especially the breeding of commercially important crops. Articles perform the valuable function of collecting, comparing, and contrasting the primary journal literature in order to form an overview of the topic. This detailed analysis bridges the gap between the specialized researcher and the broader community of plant scientists.
Improvements in adaptation and maturity leading to greater yield are the most important criteria for the acceptance of a new crop cultivar, since it is the yield which dictates the economic value of the crop. Therefore, yield improvement is one goal of virtually every crop breeding program. Many such programs have tended to concentrate on identifying the genetic traits responsible for higher yield and selecting each of them in the later stages of the breeding cycle. However, selection for yield per se is still the most effective method, since it is a combination of traits, operating within the limits of the system, which finally determines yield. This book presents a whole-system, or holistic viewpoint for the improvement of adaptation, maturity and yield. Central to its thesis is recognition that system-established changes in levels of the components of the plant system, within a constant capacity, i.e. within the limitations of the system, determines yield and other cultivar characteristics. It goes on to describe how this can improve our understanding of plant systems and enable breeders to maximize performance under prevailing field conditions. Based principally on 25 years of research by the authors, the ideas presented in this book are essential reading for crop physiologists and plant breeders.
Lupins have until recently remained wild or semi-domesticated species of minor interest to agriculture, although their value as a rotation crop was noted 2,000 years ago. However, with the advent of the science of genetics in the early twentieth century, full domestication of Lupinus species for use as crops was begun, by the combination of favourable genes such as those for low alkaloid content, non-shattering pods and soft seeds. As a result several lupin species have become an important part of temperate farming systems as a high protein crop for both animal and human consumption. This book gives an authoritative account of the history, distribution and taxonomy of Lupinus species and the current knowledge of all aspects of their agronomy and impact on agriculture, including breeding, genetics and biotechnology, nutrition, nitrogen fixation, transport physiology, toxins, stress responses, pests and diseases, agronomy and farming systems, composition and food uses, economic value and trade. Contributions are made by researchers in Australia and Europe who have had key roles in lupin research. The book is essential reading for botanists, agronomists, plant breeders and geneticists involved with lupins and other grain legumes or with an interest in crop domestication and evolution. It also provides important information for lecturers and students of agriculture and for professionals in the livestock and food industries.
The grasses and legumes grown in pastures and rangelands form the basis of the worldwide animal production industry. Some species also have a significant role in the sport and leisure industry, for playing surfaces such as golf courses and football fields. It is therefore vitally important to ensure that seed supplies of appropriate species are available for use on a commercial scale. This book is published in association with the International Herbage Seed Production Research Group. It brings together leading researchers and along with its companion volume Forage Seed Production Volume 2: Tropical and Subtropical Species (to be published in late 1998), provides the definitive resource for all those concerned with breeding and profitable seed production for grasses and legumes used within grazing systems or recreation and amenity provision. The book is in two parts. Part 1 covers all aspects relevant to seed production, including improving seed yield and quality, crop management, harvesting, processing and the international seed trade. Part 2 consists of eleven case studies from eight countries covering three continents. This book and its companion should be read by all seed scientists involved in the breeding and commercial production of grass and legume seed. They also represent a valuable asset for all commercial seed suppliers. Additionally, the information presented within the book is important for all students and lecturers within departments of agriculture and plant breeding.
Reproduction is a fundamental feature of life, it is the way life persists across the ages. This book offers new, wider vistas on this fundamental biological phenomenon, exploring how it works through the whole tree of life. It explores facets such as asexual reproduction, parthenogenesis, sex determination and reproductive investment, with a taxonomic coverage extended over all the main groups - animals, plants including 'algae', fungi, protists and bacteria. It collates into one volume perspectives from varied disciplines - including zoology, botany, microbiology, genetics, cell biology, developmental biology, evolutionary biology, animal and plant physiology, and ethology - integrating information into a common language. Crucially, the book aims to identify the commonalties among reproductive phenomena, while demonstrating the diversity even amongst closely related taxa. Its integrated approach makes this a valuable reference book for students and researchers, as well as an effective entry point for deeper study on specific topics.
Growth and Reproductive Strategies of Freshwater Phytoplankton brings both the phycological (i.e. botanical) and limnological (i.e. ecological) literature into focus to reveal the morphological, reproductive and physiological characteristics of these microscopic organisms. Emphasis is on adaptive strategies for survival in stressful and seasonally changing aquatic habitats. The synthesis of this literature from an organismal and evolutionary perspective is unique. The following important groups of planktonic algae are considered: cyanobacteria, green algae, diatoms, dinoflagellates, cryptomonads, and chrysophyte flagellates. For each algal group, the importance of both growth and loss processes influencing biogeography and seasonality is emphasised. Where appropriate, the importance of sexual reproduction and benthic resting stages is considered. The final three chapters bring together data on three major ecological processes relevant to phytoplankton, i.e. resource competition, grazing by herbivorous zooplankton, and morphological and physiological 'packaging plans' of algal cells.
Phosphorus is an essential element for plant growth and its input has long been recognized as necessary to maintain profitable crop production. However, phosphorus inputs can also increase the biological activity of surface waters and this can lead to the destruction of such aquatic ecosystems. Advanced eutrophication of surface water leads to problems with its use for fisheries, recreation, industry and drinking, due to the increased growth of undesirable algae and aquatic weeds, and oxygen shortages caused by their death and decomposition. It is therefore important to have a good understanding of the causes and mode of phosphorus loss from soil to water, to enable the problems to be controlled and managed. This book has been developed from an international workshop held in Ireland in late 1995. It is the first comprehensive consideration of the topic, and many leading researchers in the area have contributed to it. It is essential reading for all soil scientists and freshwater biologists, as well as for environmentalists, ecologists and agriculturalists concerned with sustainable land management and pollution. The book is also recommended to fisheries managers, fertilizer manufacturers and biologists working for water utilities.
Plants producing an aromatic oil, fruit, or seed have been used in religious ceremonies, for personal use and adornment, and for flavoring throughout history. There is now also world-wide pressure by consumers to use perceived natural compounds in edible and personal products. It is vital that producers should be able to service this growing demand efficiently, economically and above all reliably. Many essential oil crops are part of the economy of countries with expanding populations, resulting in increasing pressure on land to produce food and fuel. It is thus important to ensure the optimum social and economic benefit from establishing and growing essential oil crops. This book is concerned with growing essential oil plants profitably to obtain an aromatic derivative. Each chapter covers a different family. A brief history of the use and economic development is given, and cultivation, harvesting and distilling described. Results of current research and recommendations for improved agronomic practices, together with methods of adding value to the crop, such as producing honey or processing the oil, are also discussed.
Biological management of nutrient supply to plants is intrinsically more complex than the provision of nutrients as inorganic fertilizers. We need to know whether the nutrients released are retained or lost from the system, whether rates of decomposition can be manipulated to improve nutrient use efficiency, and how the various fractions of plant residues translate into pools of organic matter in soil. Only then can predictive models for nutrient release, plant uptake and soil organic matter dynamics be truly tested and validated. This book brings together contemporary ideas on the characterization and manipulation of plant quality and especially its role in soil organic matter formation and nutrient cycling. It contains work from the leading workers in both temperate and tropical systems. There are also contributions describing work outside decomposition in soil ecosystems, such as the work of plant biochemists and animal nutritionists, as research in these areas has provided many ideas and concepts used in plant quality analysis. A wide range of topics is covered from investigations at the molecular level through to management options for farmers in relation to optimising biological management of crop residues. The work presented in this volume is valuable to all those researching and managing the supply of nutrients to plants. It is important reading for soil scientists, plant physiologists and crop scientists.
Plant Adaptation and Crop Improvement focuses on the opportunities for increasing the efficiency of crop improvement by understanding the basis of variation for plant adaptation in agricultural production systems. Crop improvement strategies based on combinations of the statistical modelling methodologies used by plant breeders and the crop modelling methodologies used by crop physiologists/agronomists are developed and discussed. The book captures much of the experience of scientists from around the world who have worked on the challenging problem of achieving crop improvement in variable crop production systems. It represents a major synthesis for workers in plant breeding, crop physiology and agronomy.
Molecular farming is a biotechnological approach that includes the genetic adjustment of agricultural products to create proteins and chemicals for profitable and pharmaceutical purposes. Plant molecular farming describes the manufacture of recombinant proteins and other biologically active product in plants. This approach depends on a genetic transformation of plants that can be accomplished by the methods of stable gene transfer, such as gene transfer to nuclei and chloroplasts, and unstable transfer methods like viral vectors. The requirement for recombinant proteins in terms of quality, quantity, and diversity is increasing exponentially This demand is traditionally met by recombinant protein construction technologies and the engineering of orthodox expression systems based on bacteria or mammalian cell cultures. However, majority of developing countries cannot afford the high costs of medicine derived from such existing methods. Hence, we need to produce not only the new drugs but also the cheaper versions of those already present in the market. Plant molecular farming is considered as a cost-effective technology that has grown and advanced tremendously over the past two decades. This book summarizes the advances and challenges of plant molecular farming for all those who are working on or have an interest in this rapidly emerging area of research.
Grasses are put to a multitude of uses by those involved in agriculture and recreation. They are also of importance to environmental biologists; for example those involved in restorative ecology. In this book the biology of grasses is illustrated and elucidated through the use of many different grass genera and species, drawn from both temperate and tropical zones. Beginning with a discussion of the role of grasses in a changing world, the author provides a thorough treatment of such topics as the generation and dispersal of grasses, their diversity, history, contrasting life styles, ecology and domestication. The text is supported by the inclusion of high quality line drawings and black and white photographs. There is also a thorough glossary of the terminology associated with grass science. This book bridges the gap between introductory textbooks and research and technical papers. It is an advanced level reference text for students and teachers of agriculture, plant biology and ecology. It is of particular importance to all those studying the genetics, physiology and taxonomy of grasses.

From the emergence and genetic foundation of weeds, to the latest means of control and environmental impact, the book uses an ecological framework to explore the role of responsible and effective weed control in agriculture. In addition, users will find discussions of related areas where research is needed for additional understanding. Explored topics include the roles of culture, economics and politics in weed management, all areas that enable scientists and students to further understand the larger effects on society.
Provides an insight into current advances in the development of somatic embryogenesis, as well as the cellular and molecular mechanism, differential gene expression, and extracellular protein markers during different developing stages of somatic embryogenesis. It cover somatic embryogenesis in dicotyledons and monocotyledons plants, different factors regulating somatic embryogenesis (plant genotype, level of sugar in the medium, type and concentration of growth regulators, photoperiod, gelling agents, time exposure, induction and maturation medium), application of complex organic additives (often involves fruit juices, pulp, extracts and homogenates as well as liquid endosperms, protein hydrolysates like casein hydrolysate, tryptone, and yeast lysate like yeast extract), genetic fidelity of somatic embryos derived plantlets and role of connecting stress leading in expression of transcription factor that appears to connect stress and developmental signalling pathways and is essential for the subsequent signal transduction cascade that leads to the formation of somatic embryos. Expression of different genes associated with the accumulation of storage reserve during somatic embryogenesis along with isolation and molecular characterization of miRNAs at different developmental stages of embryogenesis, and finally proteomics during somatic embryogenesis has been discussed in detail.

From their ability to use energy from sunlight to make their own food, to combating attacks from diseases and predators, plants have evolved an amazing range of life-sustaining strategies. Written with the non-specialist in mind, John King's lively natural history explains how plants function, from how they gain energy and nutrition to how they grow, develop and ultimately die. New to this edition is a section devoted to plants and the environment, exploring how problems created by human activities, such as global warming, pollution of land, water and air, and increasing ocean acidity, are impacting on the lives of plants. King's narrative provides a simple, highly readable introduction, with boxes in each chapter offering additional or more advanced material for readers seeking more detail. He concludes that despite the challenges posed by growing environmental perils, plants will continue to dominate our planet.

Hormonal Cross-Talk, Plant Defense and Development: Plant Biology, Sustainability and Climate Change focuses specifically on plants and their interaction to auxins, gibberellins, cytokinins, ethylene, abscisic acid, jasmonates, brassinosteroids, strigolactones, and the potential those interactions offer for improved plant health and production. Plant hormones (auxins, gibberellins, cytokinins, ethylene, abscisic acid, jasmonates, brassinosteroids, salicylic acid, strigolactones etc.) regulate numerous aspects of plant growth and developmental processes. Each hormone initiates a specific molecular pathway, with each pathway integrated in a complex network of synergistic, antagonistic and additive interactions. This is a valuable reference for those seeking to understand and improve plant health using natural processes. The cross-talks of auxins - abscisic acid, auxins - brassinosteroids, brassinosteroids- abscisic acid, ethylene - abscisic acid, brassinosteroids - ethylene, cytokinins - abscisic acid, brassinosteroids - jasmonates, brassinosteroids - salicylic acid, and gibberellins - jasmonates - strigolactones have been shown to regulate a number of biological processes in plant system. The cross-talk provides robustness to the plant immune system but also drives specificity of induced defense responses against the plethora of biotic and abiotic interactions.
This book focuses on the production technology of temperate nuts. It explores cultivar and plant improvement, development and selection of rootstocks, plant–water relations and irrigation, canopy architecture, and postharvest packaging of nut fruits. It also deals with organic approaches, biotechnological interventions, diseases, and pest management. Contributing authors address nut fruits such as walnut, pecan nut, chestnut, and hazel nut on different recent aspects. The development achieved in the fruit sector is indicative of the fact that there is growing demand of fruit produce. Temperate nuts with health benefits and market acceptability have best sources of fat, fiber, protein, and mineral. They provide dietary fiber, potassium, and a variety of health-protective bioactive compounds. Apart from the health benefits, production of temperate nuts improves the economy of the country as these are very good source of income and employment. In addition, there is wide diversification in the production pattern of nuts globally. Increased production technology such as hybrids, high-yielding selections/ varieties, improved propagation techniques, and increased use of fertilizers and manures have brought spectacular increase in the production of nut fruits. This book is of interest to teachers, scientists, researchers, and scholars. Also, the book serves as additional reading material for undergraduate and postgraduate students of agriculture and horticulture. Horticulture nurseries and orchard industries also find this to be a useful read.
