Biostimulants in Alleviation of Metal Toxicity in Plants: Emerging Trends and Opportunities focuses on the role of substances or micro-organisms whose presence can address issues of metal contamination in soils, seeds and plants. Including a range of biostimulant tools, the book highlights both endogenous and exogenous application. Written and edited by a global team of experts, this book presents an overview on biostimulants in determining metal toxicity. As plants encounter a wide range of environmental challenges during their lifecycle, among which metal toxicity is a common form of abiotic stress, this book thoroughly covers important topics on the subject matter. Once inside a plant system, toxic metals may initiate a variety of physiological alterations in plants, including adversely impacted seed germination, root and shoot growth, chloroplasts ultrastructure and photosynthesis, nutrients assimilation, carbohydrates metabolism, and plant hormonal status which, collectively, results in reduced plants yields. In addition to several naturally occurring physiological and metabolic re-programing responses, plants may also modify their root and shoot systems in order to dilute entered amount of toxic metals. As an additional tool biostimulants have emerged as one of the important plant protectors under adverse conditions.

The Plant Hormone Ethylene: Stress Acclimation and Agricultural Applications presents current knowledge on our understanding of ethylene perception and signaling, its role in the regulation of plant physiological processes, and its contribution to acclimation in stressful environments. Plants regularly face environmental constraints due to their immobile nature. In persistently changing environmental conditions, several stress factors influence cellular metabolism, ultimately causing reduced plant growth and development with a significant loss in agricultural productivity. Sustainable agriculture depends on the acclimation of plant processes to the changing environment through altered physiological and molecular responses, which are controlled by plant hormones, including ethylene. Ethylene interacts with other plant hormones and signaling molecules to regulate several cellular processes, plant growth and development, and, ultimately, crop productivity. This book begins with an introduction to ethylene before providing a detailed study of the latest findings on the role of ethylene in plants, including its role in photosynthetic processes, flower development, leaf senescence, nutrients acquisition, and regulation of abiotic stress responses as well as its application in agriculture. The book is an ideal guide for researchers exploring plant physiology and biochemistry as well as for those investigating the use of ethylene knowledge in agriculture in persistently changing environmental conditions.

The assimilation of sulfur in higher plants and its reduction in metabolically important sulfur compounds are crucial factors determining plant growth and vigor and resistance to stresses. The present book discusses the aspects of sustainable crop production with sulfur, the importance of sulfur metabolites and sulfur metabolizing enzymes in abiotic stress management in plants. The book provides the most up-to-date reference on sulfur assimilation in plants.

With the advent of the industrial revolution , the biosphere has been continuously polluted with a myriad of contaminants that urgently need global attention. In this perspective, most of the genera of the plant family Brassicaceae (Crucifereae or the mustard family) are a significant part of the plants- and associated microbes-based strategies adopted for the cleanup of varied contaminants from environmental compartments. Important genus such as Alyssum, Arabidopsis, Brassica and Thlaspi from Brassicaceae which, besides acting as an attractive genetic model, well-represent the metal hyperaccumulation among approximately 0.2% of all angiosperms and thus, play a key role in the phytoremediation technology. This book i) provides an exhaustive evaluation of the current status of contaminants (metals/metalloids)-addition to varied environmental compartments and its consequences, ii) offers comprehensive and state-of-the-art information on the significance of the plants from the family Brassicaceae in solving environmental pollution issues, iii) examines the physiological, biochemical and molecular-genetic strategies adopted by the plants from Brassicaceae for the remediation of and tolerance to varied environmental contaminants, and iv) supplies a broad reference to the field of environmental science and related disciplines. As a pioneer work and significant addition to the Environmental Pollution book series, the current volume promises to be a useful asset for researchers, students, other academicians and policy makers involved in sustainable remediation of varied environmental compartments.

Phytotechnologies: Remediation of Environmental Contaminants highlights the use of natural and inherent traits of plants and associated microbes to exclude, accumulate, or metabolize a variety of contaminants, with the goal of efficiently and sustainably decontaminating the biosphere from unwanted hazardous compounds. Contributed by an international team of authors, the book ensures a balance between theory and practice without compromising the basic conceptual framework of Phytotechnologies. Divided into three major sections, the book: Introduces contaminants and contaminated sites, and also highlights the significance of genus Brassica and vetiver grass species for varied environmental contaminants' remediation Presents an exhaustive exploration of potential strategies for enhancing plants and associated microbes-mediated environmental contaminants' remediation Overviews major physiological, biochemical, and genetic-molecular mechanisms responsible for plant tolerance and adaptation to varied environmental contaminants A one-stop source of cutting edge answers and time-saving access, Phytotechnologies: Remediation of Environmental Contaminants is a common platform for engineers, environmental microbiologists, plant physiologists, and molecular biologists with the common aim of sustainable solutions to vital environmental issues. In short, the book provides a conceptual overview of ecosystems approaches and phytotechnologies, and their cumulative significance in relation to various environmental problems and potential solutions.
