Book Description
This book is the first of its kind to highlight the positive impact of natural UV radiation on plants through unique adaptations in various metabolic pathways, and provides an evolutionary sketch of the development of molecular mechanisms for protecting plants from solar UV ever since their migration to terrestrial habitats. Experimental evidence is provided for establishing how plants, through their stationary habit in the open field, survive and flourish by developing suitable UV acclimation strategies through the repair of damaged macromolecules and/or upregulation of screening compounds viz. flavonoids. Presenting an analysis of related literature, it also highlights the importance of outdoor experiments over those in closed chamber under artificial UV light for obtaining realistic data. The book presents a comprehensive account of the stratospheric ozone layer, its formation and seasonal thinning, with particular reference to alarming anthropogenic destruction of the ozone layer since the last quarter of the twentieth century, which has resulted in increased UV fluence on Earth. It discusses variations in the hazardous impact of UV on life at different latitudes through the ages, and examines altitudinal variations in UV effects in case studies demonstrating high antioxidant content and aroma status in Darjeeling tea leaves (at high altitudes) compared with those of the same tea clones in Assam leaves (at low altitudes), with both sites being at the same latitude. It provides evidence which suggests that the UV effects relating to the expression of seed vigour-viability could be epigenetic. Further, it presents recently developed microscopic technologies for demonstrating the penetration of UV into plant cells, and discusses how cellular metabolism can be affected either directly or via signal transduction. Effect of damage in DNA (the key target of UV radiation) has been demonstrated and estimated using precise techniques. The latest “FOX Hunting” technique as a useful means of transcriptome analysis that may be used for developing UV tolerant plants through Marker Assisted Breeding has also been discussed. Using biochemical and biotechnological methods, the experiments presented highlight the gene X environment based upregulation of specific metabolic pathways, allowing i) value addition in plant-derived food, and ii) paving the way for the industrial manufacture of Alternative Medicine products. The book is enriched by a critical review of the available literature and appropriate case studies selected from the author’s own findings, which span nearly four decades of active research.

Book Description
Beyond the Visible: A handbook of best practice in plant UV photobiology presents methods for research on the responses of plants to ultraviolet (UV) radiation. The knowledge needed to make informed decisions about manipulation and quantification of UV radiation is summarized. Practical recommendations for obtaining reliable and relevant data and interpretations are given. The handbook covers research both on terrestrial and aquatic plants and it deals with experimentation on ecological, eco-physiological and physiological questions. The handbook includes 115 figures, mostly in colour, 19 tables and 12 text boxes. It is the result of the activities of COST action FA0906 "UV4growth", and it includes contributions by 17 authors. From the foreword by Dr. Marcel A. K. Jansen: This book ... is an important contribution towards such sound experimental design, promoting both "good practice" in UV-B manipulation, as well as "standardisation" of methodologies. Writing an authoritative book that will steer experimental approaches over the coming years, can not easily be done by an individual, but rather requires the concerted effort of a team of expert scientists. ... This is surely an excellent example of a concerted, Europeanwide activity that will boost the plant UV-B research field in Europe and beyond, for years to come.

Book Description
Current phase-out schedules of the production and emission of CFC's indicate that chlorine loading in the stratosphere is not yet at its maximum. The recovery of stratospheric ozone is estimated to take time and ele vated levels of UV-B radiation are expected to occur throughout most of the next century. Despite numerous physiological studies of UV-B effects on plants, often grown in climate chambers, knowledge of UV-B effects on organisms and processes in natural aquatic or terrestrial ecosystems is poor. Currently it appears that UV-B radiation is not just an environmental stress' factor to plants. In various ways, which are incompletely understood, UV-B affects a wide range of physiological and ecological processes. Remarkably, recent field studies indicate that enhanced UV-B does not markedly affect photosynthesis, growth and primary production, but rather interferes with plant morphogenesis and plant and ecosystem functions relating to the secondary metabolism. This special issue and book UV-B and Biosphere is an attempt to cover this range and to report the progress made in the research of ecological effects of enhanced solar UV-B radiation. The papers in this book formed the basis of an international workshop entitled' UV-B and Biosphere' , December 15-18, 1995, in Wageningen, The Netherlands. A first reaction of Hans de Boois on the number of papers and sessions scheduled from Friday to Sunday morning was: far too many.

Book Description
Biostimulants (a diverse class of compounds including substances or microorganisms) are helpful in sustainable plants growth and development. They accelerate plant growth, yield, and chemical composition even under unfavorable conditions. The main biostimulants are nitrogen-containing compounds, humic materials, some specific compounds released by microbes, plants, and animals, various seaweed extracts, bio-based nanomaterials, phosphite, silicon, and so on. Additionally, new generation products and bioproducts are being developed for sustainable plant growth and protection. Some research works in the area of biotechnology and nanobiotechnology have shown improved sustainable plant growth and production. The protective roles of biostimulants are varied depends on the compound and plant species. Exposure of biostimulants have shown accelerated plants growth and developmental processes for instance, manage stomatal conductance and rate of transpiration, and increase rate of photosynthesis etc. They also increased crop plants immune systems against the adverse situation. Thus, use of innovations of new generation biostimulants also enhance plant production systems, through a significant reduction of synthetic chemicals such as pesticides and fertilizers. Moreover, bioinoculants commercial products obtained from seaweed extract, humic acids, amino acids, fulvic acids, and some microbial inoculants have shown their potential role in adventitious root induction in plants. Microbial inoculants or microbial-based biostimulants, as a promising and eco-friendly technology, can be widely used to address environmental concerns and fulfill the need for developing sustainable or modern agriculture practices. They have great potential to elicit plant tolerance to various climate change-related stresses and thus enhance plant growth and overall performance-related features. However, for successful implementation biostimulants-based agriculture in the field under changing climate conditions, an understanding of plant functions and biostimulants interaction or action mechanisms coping with various abiotic as well as biotic stresses at the physicochemical, metabolic, and molecular levels is required. Mycorrhizae are beneficial fungi that form symbiotic associations with plants and aid in plant development, disease resistance, and soil health is well established. Similarly, phyllospheric microbiome are known to possess different plant growth promotion attributes like nitrogen fixation, phosphate solubilization, biocontrol activity, and increase plant resistance towards abiotic stresses. The plant growth promotion traits possessed by these phyllospheric microbiota can be judiciously harbored for phyllospheric and rhizospheric engineering. The engineered phyllospheric and rhizospheric microbiome can increase the plant growth and productivity, thereby, can act as a driving force for increasing the agricultural production in a sustainable manner. Taken together, this book aims to contribute to the recent understanding associated with the various role and application of biostimulants on different plant for their sustainable growth and management. - Discusses our current understanding of, and advances in, biostimulants, along with their application in plants growth performance and overall management - Explores new techniques, new generation products, and bioproducts - Highlights the role of seaweed extract, humic acids, protein hydrolysates, amino acids, melatonin, paramylon, fulvic acids, microbial inoculants (phyllospheric and rhizospheric), and more

Book Description
This volume emphasizes the involvement of all facets of biology in the analysis of environmentally controlled movement responses. This includes biophysics, biochemistry, molecular biology and as an integral part of any approach to a closer understanding, physiology. The initial euphoria about molecular biology as the final solution for any problem has dwindled and the field agrees now that only the combined efforts of all facets of biology will at some day answer the question posed more than hundred years ago: "How can plants see?". One conclusion can be drawn from the current knowledge as summarized in this volume. The answer will most likely not be the same for all systems.

Book Description
Abiotic stress cause changes in soil-plant-atmosphere continuum and is responsible for reduced yield in several major crops. Therefore, the subject of abiotic stress response in plants - metabolism, productivity and sustainability - is gaining considerable significance in the contemporary world. Abiotic stress is an integral part of “climate change,” a complex phenomenon with a wide range of unpredictable impacts on the environment. Prolonged exposure to these abiotic stresses results in altered metabolism and damage to biomolecules. Plants evolve defense mechanisms to tolerate these stresses by upregulation of osmolytes, osmoprotectants, and enzymatic and non-enzymatic antioxidants, etc. This volume deals with abiotic stress-induced morphological and anatomical changes, abberations in metabolism, strategies and approaches to increase salt tolerance, managing the drought stress, sustainable fruit production and postharvest stress treatments, role of glutathione reductase, flavonoids as antioxidants in plants, the role of salicylic acid and trehalose in plants, stress-induced flowering. The role of soil organic matter in mineral nutrition and fatty acid profile in response to heavy metal stress are also dealt with. Proteomic markers for oxidative stress as a new tools for reactive oxygen species and photosynthesis research, abscisic acid signaling in plants are covered with chosen examples. Stress responsive genes and gene products including expressed proteins that are implicated in conferring tolerance to the plant are presented. Thus, this volume would provides the reader with a wide spectrum of information including key references and with a large number of illustrations and tables.
