Apomixis in Plants presents a comprehensive review of different aspects of asexual seed formation in plants. This is important in plant research since apomixis could greatly facilitate breeding in important crops. It is also interesting theoretically because it carries problems related to genetic variation and evolution to its extreme. The book features a broad selection of topics, including a historical review of ideas and landmarks in the field; comparisons with other types of asexual reproduction in higher plants and with related phenomena in animals and related plants; a presentation of cytology and embryology of apomicts and the diversified terminology in the field; views on the genetic background of apomixis and environmental effects on its expression; and the interrelation between apomixis and other traits. Additional topics covered include classical and modern theories of sexual versus asexual reproduction; geographical and taxonomical trends in apomicts; ecological implications of apomixis, and a review of future possibilities for using apomixis in plant breeding. Apomixis in Plants is an important reference volume for researchers and students in all areas of botany, ecology, and plant breeding.

Over the last decade considerable progress has been made in white biotechnology research and further major scientific and technological breakthroughs are expected in the future. The first large-scale industrial applications of modern biotechnology have been in the areas of food and animal feed production (agricultural/green biotechnology) and in pharmaceuticals (medical/red biotechnology). In contrast, the productions of bioactive compounds through fermentation or enzymatic conversion are known as industrial or white biotchnology. The fungi are ubiquitous in nature and have been sorted out from different habitats, including extreme environments (high temperature, low temperature, salinity and pH); and associated with plants (Epiphytic, Endophytic and Rhizospheric). The fungal strains are beneficial as well as harmful for human beings. The beneficial fungal strains may play important roles in the agricultural, industrial, and medical sectors. The fungal strains and its product (enzymes, bioactive compounds, and secondary metabolites) are very useful for industry (e.g., the discovery of penicillin from Penicillium chrysogenum). This discovery was a milestone in the development of white biotechnology as the industrial production of penicillin and antibiotics using fungi moved industrial biotechnology into the modern era, transforming it into a global industrial technology. Since then, white biotechnology has steadily developed and now plays a key role in several industrial sectors providing both high value nutraceutical and pharmaceutical products. The fungal strains and bioactive compounds also play an important role in environmental cleaning. This volume covers the latest research developments related to value-added products in white biotechnology through fungi.
Abiotic stress drastically limits agricultural crop productivity worldwide. Climate change threatens the sustainable agriculture with its rapid and unpredictable effects, making it difficult for agriculturists and farmers to respond to the challenges cropping up from environmental stresses.In light of population growth and climate changes, investment in agriculture is the only way to avert wide scale food shortages. This challenge comes at a time when plant sciences are witnessing remarkable progress in understanding the fundamental processes of plant growth and development. Plant researchershave identifiedgenes controlling different aspects of plant growth and development, but many challenges still exist in creating an apt infrastructure, access to bioinformatics and good crop results. "Improvement of Crops in the Era of Climatic Changes, Volume2"focuses on many existing opportunities that can be applied methodically through conventional breeding, without touching upon the latest discoveries such as the power of genomics to applied breeding in plant biology. Written by a diversefaction of internationally famedscholars, this volume adds new horizons in the field of crop improvement, genetic engineering and abiotic stress tolerance. Comprehensive and lavishly illustrated, "Improvement of Crops in the Era of Climatic Changes, Volume2"is a state-of-the-art guide to recent developmentsvis-a-visvarious aspects of plant responses in molecular and biochemical ways to create strong yields and overall crop improvement."
Fungi are an essential, fascinating and biotechnologically useful group of organisms with an incredible biotechnological potential for industrial exploitation. Knowledge of the world's fungal diversity and its use is still incomplete and fragmented. There are many opportunities to accelerate the process of filling knowledge gaps in these areas. The worldwide interest of the current era is to increase the tendency to use natural substances instead of synthetic ones. The increasing urge in society for natural ingredients has compelled biotechnologists to explore novel bioresources which can be exploited in industrial sector. Fungi, due to their unique attributes and broad range of their biological activities hold great promises for their application in biotechnology and industry. Fungi are an efficient source of antioxidants, enzymes, pigments, and many other secondary metabolites. The large scale production of fungal pigments and their utility provides natural coloration without creating harmful effects on entering the environment, a safer alternative use to synthetic colorants. The fungal enzymes can be exploited in wide range of industries such as food, detergent, paper, and also for removal toxic waste. This book will serve as valuable source of information as well as will provide new directions to researchers to conduct novel research in field of mycology. Volume 2 of "Industrially Important Fungi for Sustainable Development" provides an overview to understanding bioprospecting of fungal biomolecules and their industrial application for future sustainability. It encompasses current advanced knowledge of fungal communities and their potential biotechnological applications in industry and allied sectors. The book will be useful to scientists, researchers, and students of microbiology, biotechnology, agriculture, molecular biology, and environmental biology.
'A fascinating treasure trove for plant lovers and gardeners alike.' - Frances Tophill Often beautiful and sometimes strange, flowering plants have evolved to become masters of seduction. We are surrounded by extraordinary partnerships between plants and the birds, bees and other insects that pollinate them. In The Sexual Life of Flowers, botanist Simon Klein leads a beguiling and fascinating tour of the courtship between fifty flowers and the pollinators vital to their survival. From the siren scent of honeysuckle to the radiating warmth of the sunflower or the ultraviolet signal of the red poppy; tales of botanical charm, deception and intrigue are played out amid an annual explosion of activity in gardens, meadows and woodlands. Lavishly illustrated in full colour, this is a beautiful collection for gardeners and anyone with an interest in flowers.
The cropping system is one of the important components of sustainable agriculture, since it provides more efficient nutrient cycling. As such, balanced fertilization must be based on the concept of sustainable crop production. Feeding the rapidly growing world population using environmentally sustainable production systems is a major challenge, especially in developing countries. A number of studies have highlighted the fact that degradation of the world's cultivated soils is largely responsible for low and plateauing yields. Soil is lost rapidly but only formed over millennia, and this represents the greatest global threat to nutrient dynamics in agriculture. This means that nutrient management is essential to provide food and nutritional security for current and future generations. Nutrient dynamics and soil sustainability imply the maintenance of the desired ecological balance, the enhancement and preservation of soil functions, and the protection of biodiversity above and below ground. Understanding the role of nutrient management as a tool for soil sustainability and nutritional security requires a holistic approach to a wide range of soil parameters (biological, physical, and chemical) to assess the soil functions and nutrient dynamics of a crop management system within the desired timescale. Further, best nutrient management approaches are important to advance soil sustainability and food and nutritional security without compromising the soil quality and productive potential. Sustainable management practices must allow environmentally and economically sustainable yields and restore soil health and sustainability. This book presents soil management approaches that can provide a wide range of benefits, including improved fertility, with a focus on the importance of nutrient dynamics. Discussing the broad impacts of nutrients cycling on the sustainability of soil and the cropping systems that it supports, it also addresses nutrient application to allow environmentally and economically sustainable agroecosystems that restore soil health. Arguing that balanced fertilization must be based on the concept of INM for a cropping system rather than a crop, it provides a roadmap to nutrient management for sustainability. This richly illustrated book features tables, figures and photographs and includes extensive up-to-date references, making it a valuable resource for policymakers and researchers, as well as undergraduate and graduate students of Soil Science, Agronomy, Ecology and Environmental Sciences.

This book focuses on the evolution of plant viruses, their molecular classification, epidemics and management, covering topics relating to evolutionary mechanisms, viral ecology and emergence, appropriate analysis methods, and the role of evolution in taxonomy. The currently emerging virus species are increasingly becoming a threat to our way of life, both economically and physically. Plant viruses are particularly significant as they affect our food supply and are capable of rapidly spreading to new plant species. In basic research, plant viruses have become useful models to analyze the molecular biology of plant gene regulation and cell-cell communication. The small size of DNA genome of viruses possesses minimal coding capacity and replicates in the host cell nucleus with the help of host plant cellular machinery. Thus, studying virus cellular processes provides a good basis for explaining DNA replication, transcription, mRNA processing, protein expression and gene silencing in plants. A better understanding of these cellular processes will help us design antiviral strategies for plants. The book provides in-depth information on plant virus gene interactions with hosts, localization and expression and the latest advances in our understanding of plant virus evolution, their responses and crop improvement. Combining characterization of plant viruses and disease management and presenting them together makes it easy to compare all aspects of resistance, tolerance and management strategies. As such, it is a useful resource for molecular biologists and plant virologists alike.
Plant phenotyping is the thorough assessment of plant traits such as growth, development, adaptation, yield, quality, tolerance, resistance, architecture, and the basic measurement of individual quantitative parameters that form the basis for understanding of traits. Genetic approaches to understand plant growth and development have always benefitted from phenotyping techniques that are simple, rapid and measurable in units. The forward genetics approach is all about understanding the trait inheritance using the phenotypic data and in most cases it is the mutant phenotypes that formed the basis for understanding of gene functions. With rapid advancement of genotyping techniques, high throughput genotyping has become a reality at costs people never imagined to be that low, but the phenotypic methods did not receive same attention. However, without quality phenotyping data the genotyping data cannot be effectively put to use in plant improvement. Therefore efforts are underway to develop high-throughput phenotyping methods in plants to keep pace with revolutionary advancement in genotyping techniques to enhance the efficiency of crop improvement programs. Keeping this in mind, we described in this book the best phenomic tools available for trait improvement in some of the world s most important crop plants. "
Thirty years ago, in vitro propagation was a new technique for producing plants, and Lydiane Kyte s Plants from Test Tubes became the standard work on the topic.The new fourth edition has been thoroughly revised and updated to reflect the many advances in science and technology, including the five accepted sequential stages of micropropagation. Ten new plants have been added. This in turn has greatly expanded the already extensive bibliography. Among the new topics that have been introduced or expanded on are embryo culture for breeding, somaclonal variation, anther culture, somatic embryogenesis, cryopreservation, and genetic engineering. More ornamental plant examples are given and many new illustrations provided, including a chronology of discoveries in micropropagation."
This book discusses basic and applied aspects of somatic embryogenesis, one of the most powerful tools in plant biotechnology. It is divided into three parts; Part I includes topics such as the history of this research field, how differentiated plant cells can (re)acquire totipotency, molecular features, as well as the epigenetics and proteomics of somatic embryogenesis. Part II covers the somatic embryogenesis of different crops, such as Agave spp. maize, Cocos nucifera, Bixa orellana, Capsicum spp., Coffea spp., Musa spp., Pinus spp., and Arabidopsis thaliana. Various applications, like scale-up propagation and genetic engineering are discussed in detail in Part III. The book will appeal to plant scientists, plant breeders and experts working in industry.
Ferns, collectively, represent an ancient species of vascular plant which has a direct connection to the beginning of life on Earth. Today they are valued for their ornamental appeal, environmental benefit or as sources of health benefiting metabolites. Current pteridology, the study of fern, encompasses a wide range of research activities including, but not limited to, plant physiology, stress tolerance, genetics and genomics. The goal of this book is to compile the most relevant research done with ferns during the last decade. It is organized into four parts: I, Biology and Biotechnology; II, Evolution and Conservation; III, Metabolism and Genetic Resources, and IV, Environment. Each section reveals the utilization of ferns as a tool to explore challenges unique to plant development and adaptation. This project represents our collective effort to raise the awareness of ferns as a model system to study higher plant functions. Among the distinctive features of our proposed book are: (i) a wide range of topics with contributing researchers from all around the world, and (ii) recent advances of theoretic and applied knowledge with implications to crop species of economic value.

This book combines several ideas and philosophies and provides a detailed discussion on the value addition of fruits, vegetables, spices, plantation crops, floricultural crops and in forestry. Separate chapters address the packaging, preservation, drying, dehydration, total quality management and supply chain management of horticultural crops. The book explains value addition as a process of increasing the economic value and consumer appeal of a commodity with special reference to horticultural crops. Each chapter focuses on a specific area, exploring value addition as a production/ marketing strategy driven by customer needs and preferences. But, as such, it is also a more creative field, calling for more imagination than calculated, routine work. Value is added to the particular produce item when the product is still available when the season is out and the demand for the product exceeds the available supply. Value addition is an important factor in the growth and development of the horticultural sector, both in India and around the world. But very little information is available on this particular aspect of horticulture. Albert Einstein famously said, "Try not to become a man of success, but rather try to become a man of value." This message is not only true for those people who want to make more of themselves, but also for those who want their creation or product in any form to excel. And it certainly applies to horticultural crops, which are extremely perishable. It is true that loss reduction is normally less costly than equivalent increases in production. The loss of fresh produce can be minimized by adopting different processing and preservation techniques to convert the fresh vegetables into suitable value-added and diversified products, which will help to reduce the market glut during harvest season. Value-added processed products are products that can be obtained from main products and by-products after some sort of processing and subsequently marketed for an increased profit margin. Generally speaking, value-added products indicate that for the same volume of primary products, a higher price is achieved by means of processing, packing, enhancing the quality or other such methods. The integrated approach from harvesting to the delivery into the hands of the consumer, if handled properly, can add value to fresh produce on the market. But most of the fresh produce has a limited life, although it can be stored at appropriate temperature and relative humidity for the same time. If such produce is processed just after harvesting, it adds value and stabilizes the processed products for a longer time. Preparing processed products will provide more variety to consumers and improve the taste and other sensory properties of food. This will also promote their fortification with nutrients that are lacking in fresh produce. By adopting suitable methods for processing and value addition, the shelf life of fresh produce can be increased manifold, which supports their availability year-round to a wider spectrum of consumers on both the domestic and international market. With increased urbanization, rising middle class purchasing power, changing food habits and a decline in making preserved products in individual homes, there is now a higher demand for industry-made products on the domestic market. In spite of all these aspects, only 1-2.2% of the total produce is processed in developing countries, as compared to 40-83% in developed countries. The horticultural export industry offers an important source of employment for developing countries. For instance, horticulture accounts for 30% of India's agricultural GDP from 8.5% of cropped area. India is the primary producer of spices, second largest producer of fruits and vegetables and holds a prominent position with regard to most plantation crops in the world. The cultivation of horticultural crops is substantially more labor-intensive than growing cereal crops and offers more post-harvest opportunities for the development of value-added products. This book offers a valuable guide for students of horticulture, as well as a comprehensive resource for educators, scientists, industrial personnel, amateur growers and farmers.
This book offers comprehensive information on the genomics of spruces (Picea spp.), naturally abundant conifer tree species that are widely distributed in the Northern Hemisphere. Due to their tremendous ecological and economic importance, the management of forest genetic resources has chiefly focused on conservation and tree improvement. A draft genome sequence of the 20-gigabase Norway spruce genome was published in the journal Nature in 2013. Continuous efforts to improve the spruce genome assembly are underway, but are hindered by the inherent characteristics of conifer genomes: high amounts of repetitive sequences (introns and transposable elements) in the genome and large gene family expansions with regards to abiotic stress, secondary metabolism and spruces' defense responses to pathogens and herbivory. This book presents the latest information on the status of genome assemblies, provides detailed insights into transposable elements and methylation patterns, and highlights the extensive genomic resources available for inferring population genomics and climate adaptation, as well as emerging genomics tools for tree improvement programs. In addition, this volume features whole-genome comparisons among conifer species, and demonstrates how functional genomics can be used to improve gene function annotations. The book closes with an outlook on emerging fields of research in spruce genomics.
The openings offered by functional genomics reconciles organism biology and molecular biology, in order to define an integrative biology that should allow new insights about how a phenotype is built up from a genotype in interaction with its environment. This book covers a wide area of concepts and methods in genomics. This range from international genome sequencing projects to invaluable bioinformatics tools, analytical methods of gene expression, including final metabolic products, and their specific tissue to cellular compartmentalization. This new knowledge enables readers to understand the integration of basic physiological functions, and developmental programs. Also, the establishment of tight relationships between genomics, and genetics and plant breeding reveals synergies for exploiting molecular markers, for analysing genetic variation, or for studying quantitative traits. The integration that is now feasible by these new approaches also effects ecophysiology, and opens up new perspectives for the us
The existential environmental crisis prompted the United Nations to formulate the Millennium Development Goals at the turn of the 21st century in order to embark on an era of sustainable development. The progress and deficiencies in achieving the Millennium Development Goals provided impetus to the intelligentsia and policymakers to map out the pertinent goals for a sustainable growth trajectory for humanity and the planet. The United Nations' 2030 Agenda for Sustainable Development, which was adopted in September 2015, took the shape of 17 Sustainable Development Goals (SDGs) and 169 targets. In effect, the 17 Sustainable Development Goals focus on protecting the earth's life support systems for intra- and inter-generational equity and for development that is rooted in sustainability science. Attaining these goals is an uphill task; nevertheless, scientific knowledge, trans and interdisciplinary inquiries, concerted global action and capacity building would provide an enabling environment for achieving the SDGs. This book explores the synergies and trade-offs between climate change management and other SDGs. It highlights the policy imperatives as well as the interrelations between combating climate change and its impacts (SDG 13) and food and nutritional security (SDG 2), water security (SDG 6), soil security (SDG 15), energy security (SDG 7), poverty eradication (SDG 1), gender equality (SDG 5), resilient infrastructure (SDG 9), and sustainable and resilient cities (SDG 11).
This volume covers up-to-date notions of seed structure, processes resulting to its formation (syngamy, triple fusion etc.), as well as of postseminal development (seed dormancy and germination). Great attention has been paid to the morphological and functional aspects of fertilization process and embryo- and endospermogenesis.
As ancient as agriculture itself, plant breeding is one of civilization's oldest activities. Today, world food production is more dependent than ever on the successful cultivation of only a handful of major crops, while continuing advances in agriculture rely on successfully breeding new varieties that are well-adapted to their human-influenced ecological circumstances. Plant breeding involves elements of both natural and cultural selection-a process which operates on individual plants and on plant populations. This book offers the most recent detailed knowledge of plant reproduction and their environmental interaction, which can help guide new breeding programs and help insure continuing progress in providing more food for growing populations produced with better care of the environment.
The book covers both the basics of plant chromosomes as well as advances such as molecular characteristics, to give the reader an understanding of the chromosome as vehicle of hereditary transmission. It is meant for all levels of students in genetics, evolution, and biodiversity.
Ecologist Paul Colinvaux's past several years in the Amazon yield this manual written both in English and Portuguese. Consisting in part of illustrations of the principal pollen types that have been found and identified in the sediments of Amazonian lakes, this book should prove a useful tool for ecologists and climate modellers. The manual also contains brief reviews of pioneering pollen work in the Amazon to date, as well as sections on pollen methods, pollen statistics, paleoecology, and lake coring methods.
For researchers and students, George's books have become the standard works on in vitro plant propagation. For this, the third edition of the classic work, authors with specialist knowledge have been brought on board to cover the hugely expanded number of topics in the subject area. Scientific knowledge has expanded rapidly since the second edition and it would now be a daunting task for a single author to cover all aspects adequately. However, this edition still maintains the integration that was characteristic of the previous editions. The first volume of the new edition highlights the scientific background of in vitro propagation. The second volume covers the practice of micropropagation and describes its various applications.
While scientific and socio-political communities around the world are aware of the natural and economic importance of biodiversity, we are faced with an ever-increasing number of plant species under threat of extinction. Conservation is thus a vital part of the plant scientist's work, in the field, in botanic gardens and in universities. This colour atlas has been conceived to integrate the dual botanical themes of plant propagation and conservation. Various texts deal with propagation, in vivo and in vitro, and with aspects of conservation, but none marries the two themes, let alone a book which uses the concise, focused colour atlas approach. Each of the chapters has been written by an acknowledged international authority on the subject, under the editorship of Dr Bryan Bowes whose Colour Guide to Plant Structure (2nd edition 2008) is already highly successful. Topics range from the history and likely future of conservation and the effects of human activity on plant diversity, to the practical techniques of collection, preservation, germination, propagation and management of plant populations in the laboratory and in the field. The text is referenced and is illustrated throughout by colour photos and photomicrographs of the highest quality. It appeals worldwide to students of conservation, plant science and biology, and to professionals and academics, plant propagators, ecologists, and conservationists working in botanic gardens, universities and colleges, in field research and in nurseries specialising in indigenous plants.
This exciting new textbook examines the concepts of evolution as the underlying cause of the rich diversity of life on earth-and our danger of losing that rich diversity. Written as a college textbook, The Diversity and Evolution of Plants introduces the great variety of life during past ages, manifested by the fossil record, using a new natural classification system. It begins in the Proterozoic Era, when bacteria and bluegreen algae first appeared, and continues through the explosions of new marine forms in the Helikian and Hadrynian Periods, land plants in the Devonian, and flowering plants in the Cretaceous. Following an introduction, the three subkingdoms of plants are discussed. Each chapter covers one of the eleven divisions of plants and begins with an interesting vignette of a plant typical of that division. A section on each of the classes within the division follows. Each section describes where the groups of plants are found and their distinguishing features. Discussions in each section include phylogeny and classification, general morphology, and physiology, ecological significance, economic uses, and potential for research. Suggested readings and student exercises are found at the end of each chapter. |
