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.
Radiation-Processed Polysaccharides: Emerging Roles in Agriculture is the first book to focus exclusively on this emerging and important option for reducing the overuse and negative impact of agrochemicals in agriculture. Among practices being developed for effective and eco-friendly plant growth regulators in crop production, using radiation-processed polysaccharides (RPPs) is a promising technique. Comprised of chapters from diverse areas of plant science, including agriculture, agronomy, biotechnology, nanotechnology, molecular biology, and radiation agriculture, this book provides insights into the practical application of RPPs and inspires further research toward sustainable and efficient agricultural production. Polysaccharides (sodium alginate, carrageenan, chitosan and others) in their depolymerized state are increasingly important to agriculture based on their unique biological properties, biocompatibility, biodegradability and non-toxicity. Understanding the impact of RPPs on the plant phenotype, translocation of nutrients from source to sink, signal processing, and crosstalk helps improve the applicability of RPPs and sustainable agricultural yield.
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.

How can developing nations achieve cohesive national innovation systems which provide the foundations for technological progress and economic growth? In answer to this question, Technology, Development and Democracy examines the possibility of studying innovation systems using a unified approach drawing on economic, political, sociological and cultural factors and addresses the problematic concept of progress in the postmodern era. Haider Khan expresses the search for high technology as the search for 'positive feedback loop innovation systems' (POLIS). In the first part of the book the conditions for POLIS are explored both in theory and using empirical evidence. The author examines the theoretical arguments which describe an innovation system as a complex and uncertain evolutionary process. He uses empirical evidence to illustrate these arguments and examines whether South Korea's pursuit of high technology has led to the creation of a 'positive feedback loop innovation system'. The second part of the book extends the analysis of the economics of POLIS and discusses the implications of high technology systems for the polity and society at large. It also pursues some of the normative issues raised by high technology, particularly the relationship between economy and democracy. Technology, Development and Democracy will be invaluable to students and academics with an interest in economic development, technological change and political economy.
Artemisinin, a sesquiterpene lactone originally extracted from the medicinal plant Artemisia annua L., is an effective antimalarial agent, particularly for multi-drug resistant and cerebral malaria. However, the concentration of artemisinin in the plant is very low. Because the chemical synthesis of artemisinin is complicated and not economically feasible in view of the poor yield of the drug, the intact plant remains the only viable source of artemisinin production. Therefore, it is necessary to increase the concentration of artemisinin in A. annua to reduce the cost of artemisinin based antimalarial drugs. Plant scientists have focused their efforts on A. annua for a higher artemisinin crop yield. With the present volume, we are bringing together the research which is being done on this plant throughout the world and future possibilities for scientists and researchers who want to work on it.
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.

Set-valued optimization is a vibrant and expanding branch of mathematics that deals with optimization problems where the objective map and/or the constraints maps are set-valued maps acting between certain spaces. Since set-valued maps subsumes single valued maps, set-valued optimization provides an important extension and unification of the scalar as well as the vector optimization problems. Therefore this relatively new discipline has justifiably attracted a great deal of attention in recent years. This book presents, in a unified framework, basic properties on ordering relations, solution concepts for set-valued optimization problems, a detailed description of convex set-valued maps, most recent developments in separation theorems, scalarization techniques, variational principles, tangent cones of first and higher order, sub-differential of set-valued maps, generalized derivatives of set-valued maps, sensitivity analysis, optimality conditions, duality and applications in economics among other things.
This book contains the latest advances in variational analysis and set / vector optimization, including uncertain optimization, optimal control and bilevel optimization. Recent developments concerning scalarization techniques, necessary and sufficient optimality conditions and duality statements are given. New numerical methods for efficiently solving set optimization problems are provided. Moreover, applications in economics, finance and risk theory are discussed. Summary The objective of this book is to present advances in different areas of variational analysis and set optimization, especially uncertain optimization, optimal control and bilevel optimization. Uncertain optimization problems will be approached from both a stochastic as well as a robust point of view. This leads to different interpretations of the solutions, which widens the choices for a decision-maker given his preferences. Recent developments regarding linear and nonlinear scalarization techniques with solid and nonsolid ordering cones for solving set optimization problems are discussed in this book. These results are useful for deriving optimality conditions for set and vector optimization problems. Consequently, necessary and sufficient optimality conditions are presented within this book, both in terms of scalarization as well as generalized derivatives. Moreover, an overview of existing duality statements and new duality assertions is given. The book also addresses the field of variable domination structures in vector and set optimization. Including variable ordering cones is especially important in applications such as medical image registration with uncertainties. This book covers a wide range of applications of set optimization. These range from finance, investment, insurance, control theory, economics to risk theory. As uncertain multi-objective optimization, especially robust approaches, lead to set optimization, one main focus of this book is uncertain optimization. Important recent developments concerning numerical methods for solving set optimization problems sufficiently fast are main features of this book. These are illustrated by various examples as well as easy-to-follow-steps in order to facilitate the decision process for users. Simple techniques aimed at practitioners working in the fields of mathematical programming, finance and portfolio selection are presented. These will help in the decision-making process, as well as give an overview of nondominated solutions to choose from.
