Agroecological footprints are a unique and popular concept for sustainable food system. Measuring and keeping a tab on the agroecological footprints of various human activities has gained remarkable interest in the past decade. From a range of human activities, food production and agriculture are most essential as well as extremely dependent on the agroecosystems. It is therefore crucial to understand the interaction of agroecosystem constituents with the extensive agricultural practices. The environmental impact measured in terms of agroecological footprints for a healthy for the sustainable food system. The editors critically examine the status of agroecological footprints and how it can be maintained within sustainable limits. Drawing upon research and examples from around the world, the book is offering an up-to-date account, and insight into how agroecology can be implemented as a solution in the form of eco-friendly practices that would boost up the production, curbs the environmental impacts, improves the bio-capacity, and reduces the agroecological footprints. It further discusses the changing status of the agroecological footprints and the growth of other footprint tools and types, such as land, water, carbon, nitrogen, etc. This book will be of interest to teachers, researchers, government planners, climate change scientists, capacity builders, and policymakers. Also, the book serves as additional reading material for undergraduate and graduate students of agriculture, agroforestry, agroecology, soil science, and environmental sciences. National and international agricultural scientists, policymakers will also find this to be useful to achieve the 'Sustainable Development Goals'.

In the past 20 years, there has been a revolution in plant sciences, as new methods of molecular biology and biophysics have been applied to investigate environmental stress, particularly desiccation tolerance. Today, there is a good level of understanding of how plant cells cope with extreme water stress. This book is divided into four sections, dealing with 1) the technical background to desiccation tolerance studies, 2) the frequency and levels of dehydration stress tolerance in biological systems, 3) mechanisms of damage and tolerance, and 4) a brief prospect and retrospect. It covers orthodox and recalcitrant seeds, pollen and spores, vegetative parts, and other plant tissues.

This book provides a timely review of progress in the area of primary plant metabolism, and in particular highlights the extent to which molecular techniques now influence the investigation and understanding of plant metabolism. The emphasis of the book is centred on processes related to the dominant pathways of carbohydrate production and utilisation, and is arranged to reflect the current focus of researchers on three broadly overlapping areas of investigation. -- The molecular architecture of selected enzymes of primary metabolism;
-- The integration of metabolism between organelles, cells, tissues and organs;
-- The manipulation of major pathways of carbohydrate metabolism.

Each of the contributors is an internationally recognised researcher who presents a cogent summary of recent advances in the field. The volume will be of particular value to undergraduates, graduates and advanced researchers in plant biology, biotechnology and biochemistry, as well as researchers in related areas of plant physiology, crop production and horticulture who need to keep abreast of current developments in the understanding of the fundamental aspects of plant carbohydrate metabolism.

This is an outstanding survey describing medical drugs of plant origin, such as Echinacea edications, lentinan and mistletoe lectin, which have proven to be effective as immunostimulants. At a time when ever greater importance is being placed on preventive and alternative medicine, the study provides the reader with information on the physiological mechanisms of action and range of application of phytopreparations capable of inducing immunostimulatory effects when administered prophylactically or therapeutically. "Immunomodulatory Agents from Plants" addresses scientists in the pharmaceutical industry; physicians - general practitioners, internists and oncologists - who work with traditional immunostimulants; and also pharmacists wishing to improve customer service by gaining a firmer understanding of the science underlying and the clinical facts associated with drugs presently on the market.

Why don't trees get tired holding their limbs out for a hundred years? Why can a single African Violet leaf produce a dozen identical new plants? Any why don't plants bleed to death when their leaves fall off naturally? Descriptions of the plant parts too small to see without magnification provide the answers. The plant's cells and their several specialised working subunits are examined in addition to chemical traits like colour, scent, and the hormonal effects that turn leaves toward the light and allow other adaptations to the surroundings.

Recent advances in genetic engineering and in the chemistry and biochemistry of fruit and vegetables have radically changed our understanding of the mechanisms underlying these processes, and the potential for modification of the products themselves. This is the first book to examine these topics and address the role of fresh fruits and vegetables in a healthy diet and the prevention of cancer and coronary diseases. The main focus is on the secondary metabolites which are responsible for quality characteristics including color, aroma, and flavor, and their nutritional importance and role in the prevention of cancer and cardiovascular diseases. The book also explores how the post-harvest technological treatments to which these commodities are submitted can cause changes in secondary metabolism, with consequences for the quality of the product.

Until very recently genetic maps of higher plants were based almost entirely on morphological and biochemical traits. These maps are rapidly being replaced and/or supplemented with DNA-based marker maps based on the use of powerful new molecular techniques. The new high precision maps can be developed with comparative ease and rapidity. They have a much higher density of markers, which allows revelation of more and more restricted segments of the genome. One of the many revolutionary aspects of this technology is that linkage between molecular markers and traits of interest often can be detected in a single cross. The ability to hybridize probe after probe to the DNA of the same individuals of a segregating population allows one to pursue the analysis until linkage becomes evident. With morphological and biochemical markers used previously, a separate cross was required to test linkage with each new marker. It was seldom that more than three markers could be tested for linkage with the trait of interest in a single cross because of viability problems. With the new techniques described in this volume, a new gene could be placed on the linkage map within a few days instead of the much longer time required with the previous techniques. In this book, a group of leading researchers provide background information and the latest versions of DNA-based marker maps for a variety of important crops. These maps illustrate the state of the art today. The progress made during the past five years has been truly phenomenal.

Over recent years, progress in micropropagation has not been as rapid as many expected and, even now, relatively few crops are produced commercially. One reason for this is that the biology of material growing in vitro has been insufficiently understood for modifications to standard methods to be made based on sound physiological principles. However, since 1984, tissue culture companies and others have invested considerable effort to reduce the empirical nature of the production process. The idea of the conference "Physiology, Growth and Development of Plants and Cells in Culture"(Lancaster, 1992) was to introduce specialists in different areas of plant physiology to micropropagators, with the express aims of disseminating as wide a range of information to as large a number of participants as possible, and beginning new discussions on the constraints and potentials affecting the development of in vitro plant production methods. This book is based on presentations from the conference and has been divided into two main sections, dealing with aspects of the in vitro environment - light, nutrients, water, gas - and with applied aspects of the culture process - morphogenesis, acclimation, rejuvenation, contamination.

In recent years, the importance of carotenoids as light harvesting and photoprotective compounds of the photsynthetic apparatus has become apparent. In particular, advances in caratenoid photochemistry have led to significant developments in our understanding of the mechanisms of photsynthesis. This volume is a comprehensive study of the biology, biochemistry and chemistry of carotenoids in higher plants, algae and phototropic bacteria. Emphasis is placed on the photochemistry of carotenoids and the techniques used to study them. Other chapters focus on the nature and distribution of carotenoids in photosynthetic organisms, their biosynthesis and molecular biology, herbicidal inhibition of carotenogenesis and a review of the xanthophyll cycle.

This volume illuminates the disciplinary character of photosynthesis, which spans (bio)physics to agronomy. The book will help provide students with the necessary conceptual outlook for integrating information from the bioenergetic and enzymatic angles, obtained at the molecular level, with the physiology of chloroplasts, leaves and eventually crops. It therefore serves the larger interests of both students and researchers in the areas of agriculture, biotechnology, biochemistry, biophysics, plant physiology, and molecular biology, who are engaged in studying not only the basic aspects of photosynthesis, a major process determining biomass production, but also its relationship to plant productivity.

Considerable advances have been made in our understanding of the eukaryotic cell cycle at the molecular level over the past two decades or so, particularly in yeast and in animal systems. However, only in the past three or four years has progress been made in plants at the molecular level. The present volume brings together molecular biologists, cell biologists and physiologists to discuss this recent progress and how it related to our understanding of the regulation of plant growth and development. The opening paper summarises the progress which has been made with fission yeast. Subsequent papers explore what is known about cell cycle control at the molecular level in plants, and about cell cycle regulation in specific physiological systems, ending with summary papers on cell division in roots and shoots. The book comprises up-to-date findings on a fundamental aspect of plant growth and development, and as such should be of particular interest to advanced undergraduates, postgraduates and research scientists in the fields of molecular biology, cell biology and physiology.

The adaptation of desirable agricultural plants to infertile and problem soils is an increasingly important strategy for improving food supplies in many parts of the world. The plant breeding approach complements, and in some cases may replace agronomic practices such as the use of fertilizers and soil amendments to provide solutions which are economically and environmentally sustainable. The Symposium at which the papers in this volume were presented drew together workers in plant breeding, plant nutrition, physiology, biochemistry and molecular biology to discuss research on gene systems which affect the mineral nutrition of plants. Papers describe successes in plant breeding for problem soils as well as advances in understanding of mechanisms at the whole plant and cellular levels. Papers in the "molecular" area point the way to the contribution which the new biology will make to this field in the future. The reviews and research papers are grouped under five topics: better plants for acid soils; salinity tolerance; efficiency of uptake and use of macronutrients; efficiency for iron and micronutrients; and tolerance of heavy metals and boron.

The main application of genomic markers is the mapping, diagnosis, understanding, manipulation and eventual molecular cloning of loci of medical, biologic or economic interest. These achievements are likely to have a practical impact not only in basic science, e.g. in the elucidation of the basic processes involved in a particular pathway or in retracing the history of plant speciation, but also in breeding practice. In agriculture this translates into the exploitation of this knowledge for further genetic improvement since traits of agronomic interest are often polygenic. The elucidation of the genetic basis of polygenic inheritance and the subsequent efficient utilization of this knowledge in breeding schemes require the availability of an adequate network of genetic markers spanning the entire genome. The purpose of the present manual is to provide new investigators in this area with an introduction and a basic practical state-of-the-art description of how to proceed.
