The Earth's population, currently estimated at 7.86 billion, is expected to rise to 9.8 billion by 2050. This increase will inevitably lead to a greater pressure on agricultural land in order to achieve food security. However, agricultural sustainability is still constrained by its over-reliance on chemical fertilizers, pesticides, and herbicides. These conventional practices may lead to severe negative environmental consequences, typically evidenced by a loss in soil organic matter and reduction in soil microbial diversity, negatively impacting on food production. The challenging situation identified above is likely to be worsened by climate change, soil health deterioration, and by a range of biotic and abiotic stresses. Biotic and abiotic stress management, enhancement of crop yields, nutrient cycling, and natural bio-resources harnessing optimization can be achieved by modifying the soil microbiome. Discovering and exploiting potentially beneficial soil microbes is crucial to achieving sustainable agriculture production in the face of these issues. Among the plethora of potentially beneficial microbes, plant growth-promoting microbes (PGPM) and arbuscular mycorrhizal fungi (AMF) are often considered to be safe and environment-friendly tools to deal with various stresses. The interest in adopting novel methods that increase crop yield, soil health, and fertility will be positively impacted by a better understanding of the fate and behaviour of PGPM and AMF use in agriculture.

This is the fourth updated and revised edition of a well-received book that emphasises on fungal diversity, plant productivity and sustainability. It contains new chapters written by leading experts in the field. This book is an up-to-date overview of current progress in mycorrhiza and association with plant productivity and environmental sustainability. The result is a must hands-on guide, ideally suited for agri-biotechnology, soil biology, fungal biology including mycorrrhiza and stress management, academia and researchers. The topic of this book is particularly relevant to researchers involved in mycorrhiza, especially to food security, plant microbe interaction and environmental protection. Mycorrhizas are symbioses between fungi and the roots of higher plants. As more than 90% of all known species of plants have the potential to form mycorrhizal associations, the productivity and species composition and the diversity of natural ecosystems are frequently dependent upon the presence and activity of mycorrhizas. The biotechnological application of mycorrhizas is expected to promote the production of food while maintaining ecologically and economically sustainable production systems.

This book encompasses current knowledge of soil microbiomes and their potential biotechnological application for plant growth, crop yield, and soil health under the natural as well as harsh environmental conditions for sustainable agriculture. The microbes are ubiquitous in nature. The soil is a natural hotspot of the soil microbiome. The soil microbiome plays a critical role in the maintenance of global nutrient balance and ecosystem functioning. The soil microbiomes are associated with plant ecosystems through the intense network of plant–microbe interactions. The microbes present in bulk soil move toward the rhizospheric region due to the release of different nutrients by plant systems. The rhizospheric microbes may survive or proliferate in rhizospheric zone depending on the extent of influences of the chemicals secreted into the soil by roots. The root exudates contain the principal nutrients factors (amino acids, glucose, fructose, and sucrose). The microbes present in rhizospheric region have capabilities to fix atmospheric nitrogen, produce different phytohormones, and solubilize phosphorus, potassium, and zinc. The plant systems take these nutrients for their growth and developments. These soil and plant associated microbes also play an important role in protection of plants from different plant pathogenic organisms by producing different secondary metabolites such as ammonia, hydrogen cyanide, siderophores, and hydrolytic enzymes. The soil microbiomes with plant growth-promoting (PGP) attributes have emerged as an important and promising tool for sustainable agriculture. The soil microbiomes promote the plant growth and enhance the crop yield and soil fertility via directly or indirectly different plant growth-promoting mechanism. The soil microbes help the plant for adaptation in extreme habitats by mitigating the abiotic stress of high/low temperatures, hypersalinity, drought, and acidic/alkaline soil. These PGP microbes are used as biofertilizers/bioinoculants to replace the harmful chemical fertilizers for sustainable agriculture and environments. The aim of the book “Soil Microbiomes for Sustainable Agriculture” is to provide the recent advances in mechanisms of plant growth promotion and applications of soil microbiomes for mitigation of different abiotic stresses in plants. The book is useful to scientists, researchers, and students related to microbiology, biotechnology, agriculture, molecular biology, environmental biology, and related subjects.

Improve the quality and productivity of your crops through selecting positive and effective interactive core-microbiomes As microbial cells are present in overwhelming numbers in our soil, it is perhaps inevitable that microbes are found extensively in plant and animal tissue. The role of microbiomes on the regulation of physiological processes in animals has been extensively researched in recent years, but the overarching role of the plant microbiome has yet to be discovered. Core Microbiome: Improving Crop Quality and Productivity is an attempt to remediate some of that deficit, as the first book to summarize feature of microbial communities that make up the plant microbiome. There is substantial evidence that these communities are crucial in disease control, enhanced nutrient acquisition, and stress tolerance—a feature more important than ever due to climate change. A further focus on improving how core microbiomes interact so that they are both phenotypically and genotypically very adaptive and sustainable will allow the reader to improve the quality and productivity of crops so that they may be considered sustainable agriculture. Core Microbiome readers will also find: Descriptions of the basic structure of core microbiomes and their functions across various habitats New and cutting-edge trends and technological innovations highlighted that use core microbiomes to harness plant microbiome interaction The structure, classification, and biotechnological applications of aquatic core microbiomes, in addition to the material on plant microbiomes As a broad introduction to the interaction of core microbiome and plant productivity, Core Microbiome is ideal for researchers and scientists working in the field of environmental science, environmental microbiology, and waste management. Similarly, undergraduate and graduate students in these fields, as well as in agriculture, biotechnology, biosciences, and life and environmental sciences will also benefit from this work.

This book primarily focuses on microbial colonization, its role in plant growth and nutrient cycling, mycorrhizae, and providing an overview of phytospheric microorganisms in sustainable crop systems. Despite the advances made in the study of plant-microbe synergism, the relation between microbes and plant health in the context of food security, soil nutrient management, human and plant health is still largely unexplored. Addressing that gap, the book presents reviews and original research articles that highlight the latest discoveries in plant probiotics, their specificity, diversity and function. Additional sections addressing nutrient management, human health, and plant microbiome management to improve plant productivity round out the coverage.

This Research Topic addresses the mechanisms by which beneficial soil microbes, such as fungi and bacteria, protect their host plant from ‘climatic stresses’ that are increasing due to climate change. We will highlight 1) recent progress in fundamental research, 2) applied studies aimed at promoting sustainable agriculture and environmental remediation, and 3) emerging biotechnologies that promote crop adaptation to climate change. Plants respond to various climatic stresses such as drought, salinity, elevated CO2, and extreme temperatures. These responses induce changes at the molecular, cellular, and physiological levels that restrict the establishment, growth, and development of the plant. Understanding these changes has become an important research goal due to concerns about the adverse effects of climatic stresses on agriculture sustainability, global food security, and even plant-based remediation technologies. Some beneficial soil microorganisms, such as arbuscular mycorrhizal fungi and plant growth promoting bacteria, are able to protect and promote the growth of their host plants by acting as bioprotectants (via induced systemic resistance), biopesticides (via antibiotic functions) and phytostimulators (via triggering hormonal signaling networks). Plant adaptation to various climatic stresses is dynamic and involves complex cross-talk within the regulatory network (e.g. transcription factors, kinase cascades, and signaling molecules). However, the detailed molecular, cellular and physiological mechanisms underlying plant–beneficial microbe interactions in climatic stress adaptation remain largely unknown.

This book presents state-of-the-art research on the many facets of the plant microbiome, including diversity, ecology, physiology and genomics, as well as molecular mechanisms of plant-microbe interactions. Topics considered include the importance of microbial secondary metabolites in stimulating plant growth, induced systemic resistance, tolerance to abiotic stress, and biological control of plant pathogens. The respective contributions show how microbes help plants to cope with abiotic stresses, and represent significant progress toward understanding the complex regulatory networks critical to host-microbe interaction and plant adaptation in extreme environments. New insights into the mechanisms of microbial actions in inducing plant stress tolerance open new doors for improving the efficacy of microbial strategies, and could produce new ways of economically increasing crop yields without harming the environment. As such, this book offers an essential resource for students and researchers with an interest in plant-microbe interaction, as well as several possibilities for employing the plant microbiome in the enhancement of crop productivity under future climate change scenarios.
