This book covers the fundamentals of arbuscular mycorrhizal fungi (AMF) and higher plant symbiosis with potential implications in crop production. It provides new insights into our understanding of the mechanisms of AMF-mediated plant growth regulation and stress tolerance covering the most recent biochemical, physiological, molecular, environmental, and ecological studies. Focusing on AMF-induced physiological and molecular mechanisms of enhanced tolerance to stress, environmental stress is discussed in several dedicated chapters. The book provides not only updated information with new insights and perspectives but also several new topics, such as a comprehensive discussion on biotic stressors, AMF interaction with other microorganisms, non-host plant species, plant secondary metabolism, signaling events in plant-AMF symbiosis, AMF-mediated nutrient acquisition and subsequent stress tolerance. The book also discusses the potential implications of AMF for sustainable crop production inthe context of climate change. The book can be a useful reference book for academics and scientists involved in related research, such as academics in agronomy and plant sciences, scientists involved in beneficial fungi research, chemists, industrialists, and employees involved in the production and marketing of biofertilizers, master and doctoral degree students of agronomy, horticulture, and plant protection, consultants working on the production of crops in marginal environments as well as environmental scientists working for assisted phytoremediation programs. It would also be suitable for agronomy, ecology, and plant science-related courses, such as plant stress physiology, plant growth-promoting microbes, and plant pathology to teach undergraduate, graduate, and postgraduate students at colleges and universities.

This edited book compiles multifaceted functions of melatonin in plant growth, development, and stress response. The main focus of the book is to address the recent most developments in the arena of melatonin-mediated regulation of stress tolerance. Plants are continuously challenged by both biotic and abiotic stressors, which have negative impacts on growth and development. Stimulation of exogenous cues and endogenous signals can help plants to better withstand biotic and abiotic stresses. Melatonin is an important biologically active compound that acts as a multifunctional signaling molecule and regulates key physiological and biochemical processes. Currently, researchers all over the globe have been exploring the in-depth mechanisms of melatonin-modulated regulation of plant biology using various advanced molecular techniques. These recent advancements in melatonin research have possible applications in plant stress management as well as developing stress-tolerant cropvarieties. This book is of interest to university teachers, researchers, plant scientists, industry professionals, and policymakers on a global scale.It also serves as a reading material for undergraduate and graduate students of agriculture, forestry, plant biology, and environmental sciences.

This comprehensive edited volume collects the most recent information with up-to-date citations, on the decrease in plant productivity under climatic changes and its link with global food security. The book emphasis on the crop management practices and recent advancement in the techniques for mitigating the negative effects of climate induced biotic and abiotic stress. It brings together 19 chapters developed by eminent researchers in the area of plant and environmental sciences. Global climate change is increasingly becoming a concern for future of agriculture. High levels of inorganic and organic pollutants and climatic stress adversely affects the sensitive and complex equation of natural resources and ecosystem services. To meet the increased food demand, plant productivity needs to be enhanced, therefore this book fills in the gap and brings together information on the physiological and molecular approaches for improving crop productivity.The book is resourceful reading material for researchers, faculty members, graduate and post graduate students of plant science, agriculture, agronomy, soil science, botany, Molecular biology and environmental science.

Crop plants growing under field conditions are constantly exposed to various abiotic and biotic stress factors leading to decreased yield and quality of produce. In order to achieve sustainable development in agriculture and to increase agricultural production for feeding an increasing global population, it is necessary to use ecologically compatible and environmentally friendly strategies to decrease the adverse effects of stresses on the plant. Selenium is one of the critical elements from the biological contexts because it is essential for human health; however, it becomes toxic at high concentrations. It has been widely reported that selenium can promote plant growth and alleviate various stresses as well as increase the quantity and quality of the yield of many plant species. Nonetheless, at high concentrations, selenium causes phytotoxicity. In the last decade, nanotechnology has emerged as a prominent tool for enhancing agricultural productivity. The production and applications of nanoparticles (NPs) have greatly increased in many industries, such as energy production, healthcare, agriculture, and environmental protection. The application of NPs has attracted interest for their potential to alleviate abiotic and biotic stresses in a more rapid, cost-effective, and more sustainable way than conventional treatment technologies. Recently, research related to selenium-NPs-mediated abiotic stresses and nutritional improvements in plants has received considerable interest by the scientific community. While significant progress was made in selenium biochemistry in relation to stress tolerance, an in-depth understanding of the molecular mechanisms associated with the selenium- and nano-selenium-mediated stress tolerance and bio-fortification in plants is still lacking. Gaining a better knowledge of the regulatory and molecular mechanisms that control selenium uptake, assimilation, and tolerance in plants is therefore vital and necessary to develop modern crop varieties that are more resilient to environmental stress. This book provides a comprehensive overview of the latest understanding of the physiological, biochemical, and molecular basis of selenium- and nano-selenium-mediated environmental stress tolerance and crop quality improvements in plants. It helps researchers to develop strategies to enhance crop productivity under stressful conditions and to better utilize natural resources to ensure future food security and to reduce environmental contamination. Finally, this book is a valuable resource for promoting future research into plant stress tolerance, and  a reference book for researchers working on developing plants tolerant to abiotic and biotic stressors as well as bio-fortification and phytoremediation.
