Microbial Management of Plant Stresses: Current Trends, Application and Challenges explores plant microbiota including isolated microbial communities that have been used to study the functional capacities, ecological structure and dynamics of the plant-microbe interaction with focus on agricultural crops. Presenting multiple examples and evidence of the potential genetic flexibility of microbial systems to counteract the climate induced stresses associated with their host as a part of indigenous system, this book presents strategies and approaches for improvement of microbiome. As climate changes have altered the global carbon cycling and ecological dynamics, the regular and periodic occurrences of severe salinity, drought, and heat stresses across the different regimes of the agro-ecological zones have put additional constraints on agricultural ecosystem to produce efficient foods and other derived products for rapidly growing world population through low cost and sustainable technology. Furthermore chemical amendments, agricultural inputs and other innovative technologies although may have fast results with fruitful effects for enhancing crop productivity but also have other ecological drawbacks and environmental issues and offer limited use opportunities. Microbial formulations and/or microbial consortia deploying two or multiple partners have been frequently used for mitigation of various stresses, however, field success is often variable and improvement Smart, knowledge-driven selection of microorganisms is needed as well as the use of suitable delivery approaches and formulations. Microbial Management of Plant Stresses: Current Trends, Application and Challenges presents the functional potential of plant microbiota to address current challenges in crop production addressing this urgent need to bring microbial innovations into practice. - Demonstrates microbial ecosystems as an indigenous system for improving plant growth, health and stress resilience - Covers all the novel aspects of microbial regulatory mechanism. Key challenges associated with microbial delivery and successful establishment for plant growth promotion and stress avoidance - Explores plant microbiome and the modulation of plant defense and ecological dynamics under stressed environment

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.

To cope with the increasing problems created by agrochemicals such as plant fertilizers, pesticides and other plant protection agents, biological alternatives have been developed over the past years. These include biopesticides, such as bacteria for the control of plant diseases, and biofertilizer to improve crop productivity and quality. Especially plant growth promoting rhizobacteria (PGPR) are as effective as pure chemicals in terms of plant growth enhancement and disease control, in addition to their ability to manage abiotic and other stresses in plants. The various facets of these groups of bacteria are treated in this Microbiology Monograph, with emphasis on their emergence in agriculture. Further topics are Bacillus species that excrete peptides and lipopeptides with antifungal, antibacterial and surfactant activity, plant-bacteria-environment interactions, mineral-nutrient exchange, nitrogen assimilation, biofilm formation and cold-tolerant microorganisms.

Abiotic and biotic stress factors, including drought, salinity, waterlog, temperature extremes, mineral nutrients, heavy metals, plant diseases, nematodes, viruses, and diseases, adversely affect growth as well as yield of crop plants worldwide. Plant growth-promoting microorganisms (PGPM) are receiving increasing attention from agronomists and environmentalists as candidates to develop an effective, eco-friendly, and sustainable alternative to conventional agricultural (e.g., chemical fertilizers and pesticide) and remediation (e.g., chelators-enhanced phytoremediation) methods employed to deal with climate change-induced stresses. Recent studies have shown that plant growth-promoting bacteria (PGPB), rhizobia, arbuscular mycorrhizal fungi (AMF), cyanobacteria have great potentials in the management of various agricultural and environmental problems. This book provides current research of biofertilizers and the role of microorganisms in plant health, with specific emphasis on the mitigating strategies to combat plant stresses.

Recent years have seen tremendous progress in unraveling the molecular basis of different plant-microbe interactions. Knowledge has accumulated on the mecha nisms of the microbial infection of plants, which can lead to either disease or resistance. The mechanisms developed by plants to interact with microbes, whether viruses, bacteria, or fungi, involve events that can lead to symbiotic association or to disease or tumor formation. Cell death caused by pathogen infection has been of great interest for many years because of its association with plant resistance. There appear to be two types of plant cell death associated with pathogen infection, a rapid hypersensitive cell death localized at the site of infection during an incompatible interaction between a resistant plant and an avirulent pathogen, and a slow, normosensitive plant cell death that spreads beyond the site of infection during some compatible interactions involving a susceptible plant and a virulent, necrogenic pathogen. Plants possess a number of defense mechanisms against infection, such as (i) production of phytoalexin, (ii) formation of hydrolases, (iii) accumulation of hydroxyproline-rich glycoprotein and lignin deposition, (iv) production of pathogen-related proteins, (v) produc tion of oligosaccharides, jasmonic acid, and various other phenolic substances, and (vi) production of toxin-metabolizing enzymes. Based on these observations, insertion of a single suitable gene in a particular plant has yielded promising results in imparting resistance against specific infection or disease. It appears that a signal received after microbe infection triggers different signal transduction pathways.
