This edited book is focused on antioxidant compounds and their biosynthesis, up-regulation, mechanism of action for selective bioactivity, targeted role and the advancement of their bioactive potential during plant-microbe interaction and other stress conditions. This book also emphasizes on the role of antioxidants in recruiting beneficial microbes in plant surroundings. Antioxidants have multiple biological roles in plants especially in the signalling pathway. These compounds are secondary metabolites produced besides the primary biosynthetic pathway and are associated with growth and development. Besides they also have special role to play during oxidative stress produced via abiotic stimulants or pathogen attack. This understanding of the biosynthesis, signaling and function of antioxidant compounds in plants during stress condition is helpful in restoring plant ecosystem productivity and improve plant responses to a wide range of stress conditions. This book is a useful compilation for researchers and academicians in botany, plant physiology, plant biochemistry and stress physiology. Also the book serves as reading material for undergraduate and graduate students of environmental sciences, agricultural sciences and other plant science courses.
D.A. Cooke and R.K. Scott Sugar beet is one of just two crops (the other being sugar cane) which constitute the only important sources of sucrose - a product with sweeten ing and preserving properties that make it a major component of, or additive to, a vast range of foods, beverages and pharmaceuticals. Sugar, as sucrose is almost invariably called, has been a valued compo nent of the human diet for thousands of years. For the great majority of that time the only source of pure sucrose was the sugar-cane plant, varieties of which are all species or hybrids within the genus Saccharum. The sugar-cane crop was, and is, restricted to tropical and subtropical regions, and until the eighteenth century the sugar produced from it was available in Europe only to the privileged few. However, the expansion of cane production, particularly in the Caribbean area, in the late seventeenth and the eighteenth centuries, and the new sugar-beet crop in Europe in the nineteenth century, meant that sugar became available to an increasing proportion of the world's population."

Most textbooks on measuring terrestrial vegetation have focused on the characteristics of biomass, cover, and the density or frequency of dominant life forms (trees, shrubs, grasses, and forbs), or on classifying, differentiating, or evaluating and monitoring dominant plant communities based on a few common species. Sampling designs for measuring species richness and diversity, patterns of plant diversity, species-environment relationships, and species distributions have received less attention. There are compelling, urgent reasons for plant ecologists to do a far better job measuring plant diversity in this new century. Rapidly invading plant species from other countries are affecting rangeland condition and wildlife habitat, placing more plant species on threatened and endangered species lists, and increasing wildfire fuel loads. Attention has shifted from the classification of plant communities to accurately mapping rare plant assemblages and species of management concern to afford them better protection. More ecologists, wildlife biologists, and local and regional planners recognize the value in understanding patterns, dynamics, and interactions of rare and common plant species and habitats to better manage grazing, fire, invasive plant species, forest practices, and restoration activities. Thus, revised and new sampling approaches, designs, and field techniques for measuring plant diversity are needed to assess critical emerging issues facing land managers. This book offers alternatives to the approaches, designs, and techniques of the past that were chiefly designed for dominant species and other purposes. The author focuses on field techniques that move beyond classifying, mapping, and measuring plant diversity for relatively homogeneous communities. This book complements methods for measuring the biomass and cover of dominant plant species. Most species are sparse, rare, and patchily distributed. It empowers the reader to take an experimental approach in the science of plant diversity to better understand the distributions of common and rare species, native and non-native species, and long-lived and short-lived species.
This book provides case studies on cultivating alternative crops and presents new cropping systems in many regions of the world. It focusses on new emerging research topics aiming to study all aspects of adaptation under several stresses including agricultural, environmental, biological and socioeconomic issues. The book also provides operational and practical solutions for scientists, producers, technology developers and managers to succeed the cultivation of new alternative crops and, consequently, to achieve food security. Many regions in the world are suffering from water scarcity, soil and water salinization and climate change. These conditions make it difficult to achieve food security by cultivating conventional crops. A renaissance of interest for producing alternative crops under water scarcity and water salinization has been, therefore, implemented primarily among small-scale producers, researchers and academics. The use of alternative crops (quinoa, amaranth, legume crops, halophytes, ...etc.) may provide some environmental benefits such as valorization of salt-affected soils, reduced pesticide application, enhanced soil and water quality and promotion of wildlife diversity. This also may provide some economic benefits such as providing the opportunity for producers to take advantage of new markets and premium prices, spreading the economic risk and strengthening local economies and communities. Furthermore, alternative crops are often rich in proteins and minerals, and even some of them are Gluten free (quinoa). This reflects their importance to achieve food security in quantity and quality scale. The year 2013 was exceptional for alternative crops as it was the international year of quinoa celebrated by Food and Agriculture Organization (FAO). This reflects the importance of research conducted on quinoa and other alternative crops in many regions of the world.
Harold Bloom's Shakespeare examines the sources and impact of Bloom's Shakespearean criticism. Through focused and sustained study of this writer and his best-selling book, this collection of essays addresses a wide range of issues pertinent to both general readers and university classes: the cultural role of Shakespeare and of a new secular humanism addressed to general readers and audiences; the author as literary origin; the persistence of character as a category of literary appreciation; and the influence of Shakespeare within the Anglo-American educational system. Together, the essays reflect on the ethics of literary theory and criticism.
Ultimate success in exploiting the genetic capabilities of plants to grow in nutrient-stressed environments of the semi-arid tropics (SAT) requires a holistic view of food systems to ensure that genetic selections for improved yields on nutrient-poor soils will actually be adopted by farmers. This book sets out to address the important issue of how physiological mechanisms of nutrient uptake can best be combined with genetic options to improve the adaptation of crops to low-nutrient availability, thereby enhancing productivity of nutrient poor soils in the semi-arid tropics. The book examines (i) the sustainability of breeding for low-nutrient environments from the viewpoint of three interrelated disciplines; physiology, breeding, and socio-economics, (ii) candidate mechanisms and physiological traits to enhance uptake and utilization efficiencies, (iii) genetic approaches for manipulation of crop plants to enhance root exudation and access nutrients in the rhizosphere, and (iv) field practices and farmers' preferences for crop varieties grown in low-nutrient environments. Finally, the role of modelling in improving nutrient efficiency in cropping systems, recommendations for future research needs and strategies were highlighted. Attended by 50 international participants, this book is the outcome of the workshop held at ICRISAT-India during 27-30 September 1999 to mark the culmination of the Government of Japan/ICRISAT Project.
With an intricate biosynthesis pathway and a complex gene signalling cascade, auxin is involved in many biological processes, including plant growth and responses against potential pathogens. In this book, the authors present topical research in the study of the structure, biosynthesis and functions of auxins. Topics discussed include the roles of auxin during plant-microbe interactions; auxin biosynthesis and function in plants; chemicals as adjuvants in auxin induced adventitious rooting; and the effects of auxins on plant pathogenic phytoplasmas and phytoplasma-infected hosts.
Why are leaves green and blood red? The answer lies with one family of pigments, the porphyrins and their relatives. These pigments are also responsible for the fundamental energetic processes that make life as we know it possible. The properties of these colourful molecules are now being investigated for use in a wide range of applications, from cancer therapy to microelectronics. The Colours of Life is intended to be an introduction to the porphyrins and their role in life.

Introduction to Plant Physiology became the best-selling first edition plant physiology text of the 1990's! Now, we're building on the success of prior editions to provide an even more effective fourth edition. Plant Physiology has been praised for its excellent balance of traditional and modern topics, presented in a straightforward style, without overwhelming undergraduates with excessive detail. Its focus is on the ideas and experimental approaches in plant physiology. This is a one-semester course. It assumes that the student has had introductory biology or botany as a pre-requisite.
This rigorous yet accessible text introduces the key physical and biochemical processes involved in plant interactions with the aerial environment. It is designed to make the more numerical aspects of the subject accessible to plant and environmental science students, and will also provide a valuable reference source to practitioners and researchers in the field. The third edition of this widely recognised text has been completely revised and updated to take account of key developments in the field. Approximately half of the references are new to this edition and relevant online resources are also incorporated for the first time. The recent proliferation of molecular and genetic research on plants is related to whole plant responses, showing how these new approaches can advance our understanding of the biophysical interactions between plants and the atmosphere. Remote sensing technologies and their applications in the study of plant function are also covered in greater detail.
This book maintains that higher plants manifest some degree of sexual selection, and it begins to build a framework that unifies many features of plant reproduction previously considered unrelated. Reviewing evidence for sexual selection in plants, the authors discuss possible male-female interactions, concluding with an extensive set of hypotheses for testing. Mechanisms that could be employed in sexual selection in plants include various cellular mechanisms, such as both nuclear and cytoplasmic genetics, B chromosomes, and paternal contributions to the zygote, as well as abortion, double fertilization, delayed fertilization, and certain forms of polyembryony. This study compares the consequences of these processes for the evolution of mate choice in "gymnosperms" and angiosperms.
Information on chemical background, the cell, plant growth regulators and biochemistry have been integrated into the text where relevant, instead of chapters formally addressing this material.
Whereas the adult body plan of an animal is established largely during embryogenesis, the body plan of a plant is elaborated throughout its life, through the activity of meristematic tissues. Although many of the patterning mechanisms that operate during embryogenesis in animal systems are becoming understood in molecular terms, the extent to which analogous mechanisms underpin the formation and function of meristematic tissues in plants remains unclear. This volume takes a fresh look at the essential nature of meristematic tissues and the manner in which they contribute to the growth and development of the plant. Authors pay special attention to the molecular mechanisms underlying meristem formation and maintenance, while at the same time integrating them with existing physiological and anatomical information. The volume is directed at researchers and professionals in plant genetics, developmental biology, molecular biology and physiology.
"Aquatic Photosynthesis" is a comprehensive guide to understanding the evolution and ecology of photosynthesis in aquatic environments. This second edition, thoroughly revised to bring it up to date, describes how one of the most fundamental metabolic processes evolved and transformed the surface chemistry of the Earth. The book focuses on recent biochemical and biophysical advances and the molecular biological techniques that have made them possible. In ten chapters that are self-contained but that build upon information presented earlier, the book starts with a reductionist, biophysical description of the photosynthetic reactions. It then moves through biochemical and molecular biological patterns in aquatic photoautotrophs, physiological and ecological principles, and global biogeochemical cycles. The book considers applications to ecology, and refers to historical developments. It can be used as a primary text in a lecture course, or as a supplemental text in a survey course such as biological oceanography, limnology, or biogeochemistry.
This book presents a simple, straightforward discussion of the principles and processes involved in the production of grain yield by agronomic crops, and how these processes underlie and influence management decisions. The focus is on grain crops, principally maize and soybean, although the general principles apply equally well to cereals, grain legumes and oil crops. Management decisions define all cropping systems - what (crop species, variety), where (climate), when (planting date), and how (row spacing and population density) are the fundamental choices. Knowledge of the fundamental processes responsible for plant growth and the accumulation of yield simplifies the decision-making process and leads to improved management decisions, higher grain yields, and cropping systems that are efficient, resilient and sustainable. The contents include: * Basic plant growth processes e.g. photosynthesis, respiration, evapotranspiration * Growth and production of yield * Crop management - seed quality, variety selection, plant date, row spacing * Crop production in the future - climate change, GMOs, precision data and new crops Intended for researchers in crop science, agronomy and plant science, and crop production practitioners, this book will enable readers to make better, more informed management decisions; decisions that will help maintain a well-fed world in the future.
Flowers are the beautiful and complex reproductive structures of the angiosperms, one of the most diverse and successful groups of living organisms. The underlying thesis of this book is that to fully understand plant development (and why flowers differ in shape, structure and colour), it is necessary to understand why it is advantageous for them to look like they do. Conversely, in order to fully understand plant ecology, it is necessary to appreciate how floral structures have developed and evolved. Uniquely, this book addresses flowers and flowering from both a molecular genetic perspective (considering flower induction, development and self-incompatibility) and an ecological perspective (looking at the selective pressures placed on plants by pollinators, and the consequences for animal-plant co-evolution). Understanding Flowers and Flowering, the first edition of which won BES Marsh Book of the Year in 2009, begins by considering the evolution of flowers and the history of research into their development. This is followed by a detailed description of the processes which lead to flower production in model plants. The book then examines how flowers differ in shape, structure and colour, and how these differences are generated. Finally it assesses the role of these various aspects of floral biology in attracting pollinators and ensuring successful reproduction. This new edition has been completely revised and updated to reflect the latest advances in the field, especially an increased understanding of the evolution of floral traits. New chapters consider the genetic basis of the floral transition in diverse species, as well as the evolutionary lability of floral form. There is a new focus throughout on both phylogenetic position and morphological diversity across the angiosperm phylogeny. Understanding Flowers and Flowering continues to provide the first truly integrated study of the topic - one that discusses both the how and why of flowering plant reproductive biology.
Model studies focus experimental investigations to improve our understanding and performance of systems. Concentrating on crop modeling, this book provides an introduction to the concepts of crop development, growth, and yield, with step-by-step outlines to each topic, suggested exercises and simple equations. A valuable text for students and researchers of crop development alike, this book is written in five parts that allow the reader to develop a solid foundation and coverage of production models including water- and nitrogen-limited systems.
This edited book provides an overview of omics technologies and methods for integration across multiple omics layers used in the plant disease diagnosis and developing management strategies. The book concentrates on the prevalence of soil-borne disease management in various important crops with use of different strategies, including host resistance and biological control etc. The special focus is on the resolving practical problems encountered after the resistance development in the pathogens against several chemical pesticides. Further, special attention is given to the emergence of new diseases or the re-emergence of old ones on several crops, and on the results and problems encountered by using microbial inoculants, biofumigation and other non-chemical control methods. This book has 18 contributory chapters from the eminent experts in the field of plant pathology, microbiology and biotechnology working on different aspects of soil-borne diseases of important agricultural crops. This edited volume is of interest and useful to researchers in plant pathology, agriculture sciences, plant genomics ecology, policy makers, also it is a valuable source of reference to the relevant researchers and students globally.

In an important new contribution to the literature of chaos, two distinguished researchers in the field of physiology probe central theoretical questions about physiological rhythms. Topics discussed include: How are rhythms generated? How do they start and stop? What are the effects of perturbation of the rhythms? How are oscillations organized in space? Leon Glass and Michael Mackey address an audience of biological scientists, physicians, physical scientists, and mathematicians, but the work assumes no knowledge of advanced mathematics. Variation of rhythms outside normal limits, or appearance of new rhythms where none existed previously, are associated with disease. One of the most interesting features of the book is that it makes a start at explaining "dynamical diseases" that are not the result of infection by pathogens but that stem from abnormalities in the timing of essential functions. From Clocks to Chaos provides a firm foundation for understanding dynamic processes in physiology.
The edited book highlights various emerging Omics tools and techniques that are currently being used in the analysis of responses to different abiotic stress in agronomically important cereals and their applications in enhancing tolerance mechanism. Plants are severely challenged by diverse abiotic stress factors such as low water availability (drought), excess water (flooding/ waterlogging), extremes of temperatures (cold, chilling, frost, and heat), salinity, mineral deficiency, and heavy metal toxicity. Agronomically important cereal crops like Rice, Wheat, Maize, Sorghum, Pearl Millet, Barley, Oats, Rye, Foxtail Millets etc. that are the major sources of food material and nutritional components for human health are mostly exposed to abiotic stresses during the critical phases of flowering and grain yield. Different Omics platforms like genomics, transcriptomics proteomics, metabolomics and phenomics, in conjunction with breeding and transgenic technology, and high throughput technologies like next generation sequencing, epigenomics, genome editing and CRISPR-Cas technology have emerged altogether in understanding abiotic stress response and strengthening defense and tolerance mechanism of different cereals. This book is beneficial to different universities and research institutes working with different cereal crops in the areas of stress physiology, stress-associated genes and proteins, genomics, proteomics, genetic engineering, and other fields of molecular plant physiology. The book can also be used as advanced textbook for the course work of research and master's level students. It will be of use to people involved in ecological studies and sustainable agriculture. The proposed book bring together the global leaders working on environmental stress in different cereal crops and motivate scientists to explore new horizons in the relevant areas of research.
How do plants make a living? Some plants are gamblers, others are swindlers. Some plants are habitual spenders while others are strugglers and miserly savers. Plants have evolved a spectacular array of solutions to the existential problems of survival and reproduction in a world where resources are scarce, disturbances can be deadly, and competition is cut-throat. Few topics have both captured the imagination and furrowed the brows of plant ecologists, yet no topic is more important for understanding the assembly of plant communities, predicting plant responses to global change, and enhancing the restoration of our rapidly degrading biosphere. The vast array of plant strategy models that characterize the discipline now require synthesis. These models tend to emphasize either life history strategies based on demography, or functional strategies based on ecophysiology. Indeed, this disciplinary divide between demography and physiology runs deep and continues to this today. The goal of this accessible book is to articulate a coherent framework that unifies life history theory with comparative functional ecology to advance prediction in plant ecology. Armed with a deeper understanding of the dimensionality of life history and functional traits, we are now equipped to quantitively link phenotypes to population growth rates across gradients of resource availability and disturbance regimes. Predicting how species respond to global change is perhaps the most important challenge of our time. A robust framework for plant strategy theory will advance this research agenda by testing the generality of traits for predicting population dynamics. |
