Climate change and global warming are arising threats to ecology and agriculture, and the biotic and abiotic stresses on crop cultivation are becoming more severe. Simultaneously, hunger and poverty remain widespread around the world and are rather thriving with the global population increases, over-fertilization, and land degradation. Rising challenges therefore make the adaptation of agriculture to the environment even more pivotal. Plant tolerance against various stress, including abiotic and biotic stresses mostly, is a classic topic and also a hot spot, of which the goal is to provide possibilities to improve the crops’ sustainability in coping with varied environments. Sustainable crop improvement can help feed the growing population in such an era of shrinking arable land and dwindling water resources. Worldwide, the inexorable exposure of plants to the environment makes crops always come to cross biotic and abiotic stresses, which constantly affect the food supply. Scientists have devoted efforts to improve crop resistance against devastating stressors such as drought, salt, nutrition deprivation, pests and pathogens, etc., and save yields from destruction. With the explosive development of omics technologies, e.g., genomics, transcriptomics, proteomics, metabolomics, interactomics, and phenomics, crop improvement is embarking on a fire-new bioinformatics era. The integration of multi-omics will provide new perspectives to understand the intricate nature of stress response in crops

The use of biocontrol agents and beneficial organisms for management of plant and pest diseases appears as an environment-friendly and economic procedure. However, this option is not always available, depending on the lack of knowledge on the mechanisms of natural regulation, locally effective. In this view, this eBook considers studies and experimental works illustrating a range of problems and solutions based on microbial resources, suitable for management of biotic stress factors. These examples show how detailed data and knowledge on the organisms involved are of paramount importance to achieve a sustainable and durable management capability.

Beginning with the germ theory of disease in the 19th century and extending through most of the 20th century, microbes were believed to live their lives as solitary, unicellular, disease-causing organisms . This perception stemmed from the focus of most investigators on organisms that could be grown in the laboratory as cellular monocultures, often dispersed in liquid, and under ambient conditions of temperature, lighting, and humidity. Most such inquiries were designed to identify microbial pathogens by satisfying Koch's postulates.3 This pathogen-centric approach to the study of microorganisms produced a metaphorical "war" against these microbial invaders waged with antibiotic therapies, while simultaneously obscuring the dynamic relationships that exist among and between host organisms and their associated microorganisms-only a tiny fraction of which act as pathogens. Despite their obvious importance, very little is actually known about the processes and factors that influence the assembly, function, and stability of microbial communities. Gaining this knowledge will require a seismic shift away from the study of individual microbes in isolation to inquiries into the nature of diverse and often complex microbial communities, the forces that shape them, and their relationships with other communities and organisms, including their multicellular hosts. On March 6 and 7, 2012, the Institute of Medicine's (IOM's) Forum on Microbial Threats hosted a public workshop to explore the emerging science of the "social biology" of microbial communities. Workshop presentations and discussions embraced a wide spectrum of topics, experimental systems, and theoretical perspectives representative of the current, multifaceted exploration of the microbial frontier. Participants discussed ecological, evolutionary, and genetic factors contributing to the assembly, function, and stability of microbial communities; how microbial communities adapt and respond to environmental stimuli; theoretical and experimental approaches to advance this nascent field; and potential applications of knowledge gained from the study of microbial communities for the improvement of human, animal, plant, and ecosystem health and toward a deeper understanding of microbial diversity and evolution. The Social Biology of Microbial Communities: Workshop Summary further explains the happenings of the workshop.

Soilborne microbial plant pathogens including oomycetes, fungi, bacteria and viruses cause several economically important destructive diseases and the symptoms of infection can be recognized only after the pathogen has invaded many tissues primarily vascular tissues of susceptible plants. This condition places formidable challenges in investigating different aspects of host-microbial pathogen interactions. Early detection of infection and precise identification, differentiation, and quantification of the microbial plant pathogens in plants, soil and water sources are essential requirements for development of effective tactics to reduce the incidence and spread of the diseases caused by them. As the microbial plant pathogens differ in their virulence and sensitivity to the environment and chemicals applied, it is imperative to assess the extent of variability in the concerned pathogens. This first volume of a two-volume set introduces disease-causing microorganisms including oomycetes, fungi, bacteria, and viruses found in soils. It focuses on the biology, detection, and identification of soilborne bacterial, fungal, and viral plant pathogens. This volume discusses various techniques based on biological, immunological and genetic properties of the pathogens indicating their advantages and limitations for selecting the appropriate technique to fulfill the requirements. Features: Presents techniques useful for detection, identification, quantification of microbial plant pathogens in plants, soil, and irrigation water from waterbodies. Highlights subversive activities of viruses, resulting in the breakdown of host defense systems. Discusses RNA silencing in infected plants by viruses and posttranscriptional gene silencing (PTGS) functioning as an endogenous mechanism in plants against virus infection. Presents information on methods of assessment of genetic variability and sensitivity of microbial plant pathogens to chemicals and adverse environmental conditions.

The rhizosphere is an ecological hotspot. Plant roots, bacteria, archaea, fungi, nematodes, and other macroscopic organisms interact here with each other. Plants represent the main influencing force as they produce a mixture of chemical molecules and extrude them in the form of root exudates. Those exudates determine not only the nutrient availability of the plant but also influence the outcome of the interactions in the vicinity of the roots. In response to the plant-derived signals, a subset of the bulk soil microbes can proliferate in the proximity of the root and some of them can eventually overcome the plant defense system to colonize the plants. The root-associated microbiota is assumed to be crucial for plant health, and belowground plant-microbe and microbe-microbe interactions can result in altered growth and nutritional quality of the aboveground plant parts. Such interactions affect community composition and productivity in natural ecosystems or crop yield in agricultural fields. Root associations with plant growth-promoting rhizobacteria (PGPR) producing phytohormones that alter root architecture, or produce antibiotics to suppress antagonistic pathogens, affecting nutrient availability and competition between plants are just a few among many examples of such belowground interactions in the rhizosphere. Moreover, the role of rhizosphere microorganisms in stimulating the plant immune system leading to Induced Systemic Resistance (ISR) has also been a focus of an active investigation. However, the molecular mechanisms are still largely unknown. On one hand, it has been proposed that plants actively recruit beneficial microorganisms under certain pathological conditions or influence the soil microbial communities and create a so-called “soil memory”, which is conveyed to future plant generations. On the other, the presence and interactions between microorganisms in the soil have a substantial impact on plant health.
