Bananas and plantains are among the most important food and cash crops in the world. They are cultivated in more than 135 countries, across the tropics and subtropics, with an annual global production of ca. 130 million metric tonnes. Though bananas are one of the most important components of food security in many developing countries, banana production is threatened by both abiotic and biotic stresses. These include a wide range of diseases and pests, such as bunchy top virus, burrowing nematodes, black Sigatoka or black leaf streak, Fusarium wilt, etc. In recent years, considerable progress has been made and several biotechnological and genomic tools have been employed to help understand and unravel the mysterious banana genome. Molecular and genomic studies have helped to decipher the Musa genome and its evolution. Genetic linkage map and whole genome sequencing of both Musa acuminata and Musa balbisiana (progenitors of cultivated banana) have completely changed the way of thinking and the approach on banana crop improvement. Whole-genome sequencing has helped to improve the selection of quantitative traits such as yield, as well as the selection of optimal parents for developing required hybrids in breeding programs. Gene isolation and the analysis of mutants have helped in the characterization of genes of agronomic value and the associated regulatory sequences. With the advent of molecular markers and new statistical tools, it is now possible to measure the diversity, identify genes and useful alleles linked to important agronomic traits. Further these alleles can be incorporated into cultivars through marker assisted selection or through transgenic approach. Transgenic approaches are potential tools for direct transfer of these genes into popular cultivars, which are generally not amenable for conventional breeding techniques, in specific with crops such as bananas which are sterile, triploid and heterozygous thereby making it difficult to reconstruct the recurrent genotypes in banana. Transgenic techniques thus have helped overcome the difficulty of working with sterile, triploid banana crop. In the last five years, enormous amount of new information and techniques have been generated for banana. A comprehensive book entitled "Banana: Genomics and Transgenic Approaches for Genetic improvement" on banana genomics, latest transgenic technologies and tools available for improved crop development in banana will address all these requirements.

This text details the plant-assisted remediation method, "phytoremediation", which involves the interaction of plant roots and associated rhizospheric microorganisms for the remediation of soil contaminated with high levels of metals, pesticides, solvents, radionuclides, explosives, crude oil, organic compounds and various other contaminants. Many chapters highlight and compare the efficiency and economic advantages of phytoremediation to currently practiced soil and water treatment practices. Volume 5 of Phytoremediation: Management of Environmental Contaminants provides the capstone of the series. Taken together, the five volumes provide a broad-based global synopsis of the current applications of phytoremediation using plants and the microbial communities associated with their roots to decontaminate terrestrial and aquatic ecosystems.

The knowledge of ecology and epidemiology of rhizomania is particularly useful to understand the means and practices able to limit or avoid its further diffusion. Some promising methods of biological control using coexisting and non-pathogenic organisms could potentially help improve the action of the not completely effective genetic resistances. This integrated protection would be valuable, especially in the even more frequent development of resistance-breaking strains in the BNYVV, where the known types of resistance, alone or in combination, seem to have lost part of their original ability to protect the crop. Therefore, further efforts will be needed to discover new traits likely still present in the wild species of the genus Beta. The availability of large collections of germplasm stored in the International Beta gene-banks should ensure the enhanced efficiency of genetic resistance by means of conventional and marker-assisted selection methods. Some almost immune transgenic varieties seem already to be waiting for release where and when it will be possible. The introduction chapter describes briefly the sugar beet crop, the more common diseases, and the damage caused by rhizomania. The following chapters discuss biological properties of the causal virus, BNYVV, and its vector, Polymyxa betae, and their interactions with the environment and the host-plant. In particular, the great advances in research of the molecular biology of BNYVV should be noteworthy, which have been established by a wide range of the most modern methods. Recent work focused on the genetic diversity and evolution of BNYVV is moving forward our understanding of the dramatic worldwide epidemics of rhizomania. Newly developed molecular techniques also lead to practical applications, such as quantification of inoculum in ecological and epidemiological research.

This book describes the three gasotransmitters nitric oxide (NO), hydrogen sulphide (H2S) and carbon monoxide (CO) and their function as intracellular signalling molecules in plants. Common properties are shared by NO, H2S and CO: they are beneficial at low concentrations but hazardous in higher amounts; they are small molecules of gas; they can freely cross cell membranes; their effects do not rely on receptors; they are generated enzymatically and their production is regulated; their functions can be mimicked by exogenous application; and their cellular effects may or may not be mediated by second messengers, but have specific cellular and molecular targets. In plants, many aspects of the biology of gasotransmitters remain completely unknown and generate intriguing questions, which will be discussed in this book.

This book provides an up-to-date overview of redox signaling in plant cells and its key role in responses to different stresses. The chapters, which are original works or reviews, focus on redox signaling states; cellular tolerance under different biotic and abiotic stresses; cellular redox homeostasis as a central modulator; redox homeostasis and reactive oxygen species (ROS); redox balance in chloroplasts and mitochondria; oxidative stress and its role in peroxisome homeostasis; glutathione-related enzyme systems and metabolism under metal stress; and abiotic stress-induced redox changes and programmed cell death. The book is an invaluable source of information for plant scientists and students interested in redox state chemistry and cellular tolerance in plants.

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.

This volume showcases current ethnobiological accounts of the ways that people use plants to promote human health and well-being. The goal in this volume is to highlight some contemporary examples of how plants are central to various aspects of healthy environments and healthy minds and bodies. Authors employ diverse analytic frameworks, including: interpretive and constructivist, cognitive, political-ecological, systems theory, phenomenological, and critical studies of the relationship between humans, plants and the environment. The case studies represent a wide geographical range and explore the diversity in the health appeals of plants and herbs. The volume begins by considering how plants may intrinsically be 'healthful' and the notion that ecosystem health may be a literal concept used in contemporary efforts to increase awareness of environmental degradation. The book continues with the exploration of the ways in which medically-pluralistic societies demonstrate the entanglements between the environment, the state and its citizens. Profit driven models for the extraction and production of medicinal plant products are explored in terms of health equity and sovereignty. Some of the chapters in this volume work to explore medicinal plant knowledge and the globalization of medicinal plant knowledge. The translocal and global networks of medicinal plant knowledge are pivotal to productions of medicinal and herbal plant remedies that are used by people in all variety of societies and cultural groups. Humans produce health through various means and interact with our environments, especially plants, in order to promote health. The ethnographic accounts of people, plants, and health in this volume will be of interest to the fields of anthropology, biology and ethnobiology, as well as allied disciplines.

This book critically reviews advances in our understanding of the biology of vascular epiphytes since Andreas Schimper's 1888 seminal work. It addresses all aspects of their biology, from anatomy and physiology to ecology and evolution, in the context of general biological principles. By comparing epiphytes with non-epiphytes throughout, it offers a valuable resource for researchers in plant sciences and related disciplines. A particular strength is the identification of research areas that have not received the attention they deserve, with conservation being a case in point. Scientists have tended to study pristine systems, but global developments call for information on epiphytes in human-disturbed systems and the response of epiphytes to global climate change.

This book serves the larger community of plant researchers working on the taxonomy, species delimitation, phylogeny, and biogeography of pseudo-cereals, with a special emphasis on amaranths. It also provides extensive information on the nutritive value of underutilized pseudo-cereals, the goal being to broaden the vegetable list. Amaranthus is a cosmopolitan genus of annual or short-lived perennial plants. Most of the species are summer annual weeds and are commonly referred to as pigweed. Only a few are cultivated as vitamin-rich vegetables and ornamentals. The protein-rich seeds of a handful of species, known as grain amaranths, are consumed as pseudo-cereals. Amaranthusmanifests considerable morphological diversity among and even within certain species, and there is no general agreement on the taxonomy or number of species. Currently the genus Amaranthus is believed to include three recognized subgenera and 70 species. Amatanthus is considered to potentially offer an alternative crop in temperate and tropical climate. The classification of amaranths is ambiguous due to the lack of discrete and quantitative species-defining characteristics and the wide range of phenotypic plasticity, as well as introgression and hybridization involving weedy and crop species. It is a known fact that both vegetable and grain amaranths have evolved from their respective weed progenitors. There are more than 180 different weed species that are herbicide-resistant, and amaranths are considered to be leading members of the resistant biotypes. Amaranth species provide ample scope for investigating herbicide resistance mechanisms. Amaranths also show variability in terms of their mating behavior and germplasm, adaptability to different growing conditions, and wide range of variability in sexual systems, from monoecy to dioecy. A solid grasp of these parameters is essential to the future utilization of amaranths as super crops. There are quite a few amaranth research center and germplasm collections all over the world that maintain and evaluate working germplasms. To date, the genetic improvement of amaranths has primarily involved the application of conventional selection methods. But advances in genomics and biotechnology have dramatically enriched the potential to manipulate the amaranth genome, especially improving the amount and availability of nutrients. In conclusion, the book covers all aspects of amaranths, including their food value, significance as vegetables and pseudo-cereals, taxonomy, phylogeny, germplasm variability, breeding behavior and strategies, cultivation practices, and variability in terms of their sexual systems. It offers a valuable resource for all students, researchers and experts working in the field of plant taxonomy and diversity.

This book details the plant-assisted remediation method, "phytoremediation", which involves the interaction of plant roots and associated rhizospheric microorganisms for the remediation of soil contaminated with high levels of metals, pesticides, solvents, radionuclides, explosives, crude oil, organic compounds and various other contaminants. Each chapter highlights and compares the beneficial and economical alternatives of phytoremediation to currently practiced soil removal and burial practices.

This book highlights the implications of nanotechnology in plant sciences, particularly its potential to improve food and agricultural systems, through innovative, eco-friendly approaches, and as a result to increase plant productivity. Topics include various aspects of nanomaterials: biophysical and biochemical properties; methods of treatment, detection and quantification; methods of quantifying the uptake of nanomaterials and their translocation and accumulation in plants. In addition, the effects on plant growth and development, the role of nanoparticles in changes in gene and protein expression, and delivery of genetic materials for genetic improvement are discussed. It also explores how nanotechnology can improve plant protection and plant nutrition, and addresses concerns about using nanoparticles and their compliances. This book provides a comprehensive overview of the application potential of nanoparticles in plant science and serves as a valuable resource for students, teachers, researchers and professionals working on nanotechnology.

This book provides an overview of the current state of knowledge of the genetics and genomics of the agriculturally important Cucurbitaceae plant family, which includes crops such as watermelon, melon, cucumber, summer and winter squashes, pumpkins, and gourds. Recent years have resulted in tremendous increases in our knowledge of these species due to large scale genomic and transcriptomic studies and production of draft genomes for the four major species, Citrullus lanatus, Cucumis melo, Cucumis sativus, and Cucurbita spp. This text examines genetic resources and structural and functional genomics for each species group and across species groups. In addition, it explores genomic-informed understanding and commonalities in cucurbit biology with respect to vegetative growth, floral development and sex expression, fruit growth and development, and important fruit quality traits.

This book clearly defines ways to maximize the allelopathic potential of important field crops for controlling weeds, either in the same crop or others. Compared to the use of herbicides, allelopathy is an attractive option to control weeds naturally under field conditions. The book highlights the allelopathic potential of several important cereals (wheat, maize, rice, barley, sorghum, rye) and two oilseed crops [sunflower and canola (as well as some other member of Brassicaceae family)]. Further, the book explains how the allelopathic potential of these crops can be manipulated under field conditions to suppress weeds. This is possible by growing allelopathic crop cultivars, using mulches from allelopathic crops, intercropping an allelopathic crop with a non-allelopathic crop, including allelopathic crops in crop rotation, or using allelopathic crops as cover crops. Equipped with several basic concepts of allelopathy, this book will be highly useful for the farming community as well as students and researchers.

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 field of plant breeding has grown rapidly in the last decade with breakthrough research in genetics and genomics, inbred development, population improvement, hybrids, clones, self-pollinated crops, polyploidy, transgenic breeding and more. This book discusses the latest developments in all these areas but explores the next generation of needs and discoveries including omics beyond genomics, cultivar seeds and intellectual and property rights. This book is a leading-edge publication of the latest results and forecasts important areas of future needs and applications.

This book provides detailed and comprehensive information on oxidative damage caused by stresses in plants with especial reference to the metabolism of reactive oxygen species (ROS). In plants, as in all aerobic organisms, ROS are common by-products formed by the inevitable leakage of electrons onto O2 from the electron transport activities located in chloroplasts, mitochondria, peroxisomes and in plasma membranes or as a consequence of various metabolic pathways confined in different cellular loci. Environmental stresses such as heat, cold, drought, salinity, heavy-metal toxicity, ozone and ultraviolet radiation as well as pathogens/contagion attack lead to enhanced generation of ROS in plants due to disruption of cellular homeostasis. ROS play a dual role in plants; at low concentrations they act as signaling molecules that facilitate several responses in plant cells, including those promoted by biotic and abiotic agents. In divergence, at high levels they cause damage to cellular constituents triggering oxidative stress. In either case, small antioxidant molecules and enzymes modulate the action of these ambivalent species.

This book offers an up-to-date review of the regulatory role of nitric oxide (NO) changes in the morphological, physio-biochemical as well as molecular characteristics of plants under abiotic stress. The first of two parts comprises four chapters and focuses on the properties, chemical reactions involving NO and reactive nitrogen species in plants. The second part, consisting of eleven chapters, describes the current understanding of the role of NO in the regulation of gene expression, NO signaling pathways and its role in the up-regulation of the endogenous defense system and programmed cell death. Furthermore, its interactions with other signaling molecules and plant hemoglobins under environmental and soil related abiotic stresses, including post-harvest stress in fruits, vegetables and ornamentals and wounding are discussed in detail. Together with the companion book Nitric Oxide in Plants: Metabolism and Role in Stress Physiology, this volume provides a concise overview of the field and offers a valuable reference work for teachers and researchers in the fields of plant physiology, biochemistry and agronomy.

This book presents a holistic view of the complex and dynamic responses of plants to nanoparticles, the signal transduction mechanisms involved, and the regulation of gene expression. Further, it addresses the phytosynthesis of nanoparticles, the role of nanoparticles in the antioxidant systems of plants and agriculture, the beneficial and harmful effects of nanoparticles on plants, and the application of nanoparticles and nanotubes to mass spectrometry, aiming ultimately at an analysis of the metabolomics of plants. The growing numbers of inventions in the field of nanotechnology are producing novel applications in the fields of biotechnology and agriculture. Nanoparticles have received much attention because of the unique physico-chemical properties of these compounds. In the life sciences, nanoparticles are used as “smart” delivery systems, prompting the Nobel Prize winner P. Ehrlich to refer to these compounds as “magic bullets.” Nanoparticles also play an important role in agriculture as compound fertilizers and nano-pesticides, acting as chemical delivery agents that target molecules to specific cellular organelles in plants. The influence of nanoparticles on plant growth and development, however, remains to be investigated. Lastly, this book reveals the research gaps that must be bridged in the years to come in order to achieve larger goals concerning the applications of nanotechnology in the plants sciences. In the 21st century, nanotechnology has become a rapidly emerging branch of science. In the world of physical sciences, nanotechnological tools have been exploited for a broad range of applications. In recent years, nanoparticles have also proven useful in several branches of the life sciences. In particular, nanotechnology has been employed in drug delivery and related applications in medicine.

A proper understanding of the structural organization of the plant body is essential to any study in plant biology. Experimental studies in vivo and in situ will lead to structural, physiological, and cellular changes of the experimental material. To study macroscopic and microscopic changes, different histological methods and microtechniques can be used as they provide valuable information of the experimental system. In addition, the observed structural changes allow investigators to set hypothesis for further studies based on one's own observation. Thus, proper selection and utilization of microtechniques are a must for the success of a research program. At present, an up-to-date collection of protocols are not readily available in the literature. The latest work in plant microtechniques was published in 1999 by Ruzin but many others are no longer in print [e.g., Jensen (1964); O'Brien and McCully (1981)]. Furthermore, a majority of published works focus on techniques related to general processing and staining procedures. A comprehensive treatment that encompasses broader applications of microtechniques to other disciplines is lacking [e.g., archeology, wood science, etc.]. There is a need to create a comprehensive volume of botanical methods and protocols which includes traditional and novel techniques that can be used by researchers in plant science and investigators in other disciplines that require plant microtechniques in their research and teaching. This book covers a wide variety of applications and brings them up-to-date to make them understandable and relevant, especially to students using the methods for the first time. It is our intention to create a useful reference for plant histology and related methods that will serve as a foundation for plant scholars, researchers, and teachers in the plant sciences.

This book is a biography of a scientist who pioneered the development of plant pathology in Australia in the 19th and early 20th century, and was internationally acclaimed. After 20 years as a plant pathologist, he was asked to find the cause and cure of a serious physiological disorder of apples. While the cause eluded him, and everyone else for another 60 years, he again won international gratitude for the improvements he brought to the apple industry. However because he did not find the cause, he was deemed to have failed by his political masters who were malignantly influenced by a jealous rival. The discovery in 2012-2013 of government files covering the period of the bitter pit investigation, from 1911 to 1916; reveal the extent of the unjust criticism of McAlpine while history has vindicated the management recommendations made to reduce bitter-pit losses. The focus on bitter-pit management late in McAlpine's Career also meant that those who value his memory have been less aware of the remarkable achievements of McAlpine in the time before he left Great Britain - the brilliance of his teaching and drawing skills -featured in the early teaching texts for botany and zoology (the latter with his brother) which are now accessible on-line. The objective of this book is to demonstrate that (i) the view that McAlpine had failed in his quest was wrong and seriously unjust (ii) McAlpine achievements extend beyond plant pathology and include significant contributions to the 19th century teaching of botany and zoology, contributions which reinforce the adage - a picture is worth a 1,000 words.

This monograph provides an overview of beneficial plant-bacterial interactions in a straightforward and easy-to-understand format, and includes a wealth of unique illustrations elaborating every major point. Study questions that emphasize the key points are provided at the end of each chapter. One way to feed all of the people in the world’s growing population is through the increased use of plant-growth-promoting bacteria in agriculture. These bacteria not only directly promote growth but also protect plants against a wide range of biotic and abiotic stresses. Moreover, they can be used to support procedures for biologically cleaning up the environment. Plant-growth-promoting bacteria are already being used successfully on a small scale in several countries, and as this technology matures, the world may witness a major paradigm shift in agricultural practice.

Genetics has transformed plant pathology on two occasions: first when Mendelian genetics enabled the discovery that disease resistance was a heritable trait in plants, and secondly when Flor proposed the "gene-for-gene" hypothesis to explain his observations of plant-parasite interactions, based on his work on flax rust in North Dakota starting in the 1930s. Our knowledge of the genetics of disease resistance and host-pathogen coevolution is now entering a new phase as a result of the cloning of the first resistance genes. This book provides a broad review of recent developments in this important and expanding subject. Both agricultural and natural host-pathogen situations are addressed. While most of the book focuses on plant pathology, in the usual sense of the term embracing fungal, bacterial and viral pathogens, there is also consideration of parasitic plants and a chapter demonstrating lessons to be learnt from the mammalian immune system. Three overall themes are addressed: genetic analyses and utilization of resistance; population genetics; and cell biology and molecular genetics. Chapters are based on papers presented at the British Society for Plant Pathology Presidential meeting held in December 1995, but all have been revised and updated to mid-1996. Written by leading authorities from North America, Europe and Australia, the book represents an essential update for workers in plant genetics, breeding, biotechnology and pathology.

The sequencing of genomes has been completed for an increasing number of crop species, and researchers have now succeeded in isolating and characterising many important QTLs/genes. High expectations from genomics, however, are waving back toward the recognition that crop physiology is also important for realistic improvement of crop productivity. Complex processes and networks along various hierarchical levels of crop growth and development can be thoroughly understood with the help of their mathematical description - modelling. The further practical application of these understandings also requires quantitative predictions. In order to better support design, engineering and breeding for new crops and cultivars for improving agricultural production under global warming and climate change, there is an increasing call for an interdisciplinary research approach, which combines modern genetics and genomics, traditional physiology and biochemistry, and advanced bioinformatics and modelling. Such an interdisciplinary approach has been practised in various research groups for many years. However, it does not seem to be fully covered in the format of book publications. We want to initiate a book project on crop systems biology - narrowing the gaps between genotypes and phenotypes and the gaps between crop modelling and genetics/genomics, for publication in 2013/2014. The book will be meant for those scientists and graduate students from fundamental plant biology and applied crop science who are interested in bridging the gap between these two fields. We have invited a group of scientists (who have very good track records in publishing excellent papers in this field or in a closely related area) to contribute chapters to this new book, and they have agreed to do so.
