The future of agriculture strongly depends on our ability to enhance productivity without sacrificing long-term production potential. An ecologically and economically sustainable strategy is the application of microorganisms, such as the diverse bacterial species of plant growth promoting bacteria (PGPB). The use of these bio-resources for the enhancement of crop productivity is gaining worldwide importance. "Bacteria in Agrobiology: Stress Management" covers the major aspects on PGPR in amelioration of both abiotic and biotic stresses. PGPR mediated in priming of plant defense reactions, nutrient availability and management in saline and cold environment, hormonal signaling, ACC deaminase and its role in ethylene regulation under harsh conditions are suitably described.

To meet the food security needs of the 21st century, this book focuses on ecofriendly and sustainable production technologies based on plant growth promoting rhizobacteria (PGPR). It is estimated that the global population could increase to 9 billion by 2050. Further, the amount of land devoted to farming has decreased. Soil is a living entity, and is not only a valuable natural resource for agricultural and food security, but also for the preservation of all life processes. Agricultural productivity rests on the foundation of microbial diversity in the soil, and in recent years, PGPR have emerged as an important and promising tool for sustainable agriculture. The injudicious use of agrochemicals by farmers has created a range of negative impacts, not only threatening the environment, but also destroying useful microorganisms in the soil. The efficient use of PGPR reduces the need for these chemicals while simultaneously lowering production costs. In turn, increased yields could provide a more favourable environment and encourage sustainability. This book assesses the impacts of PGPR on crops, environmental and socio-economic sustainability, and demonstrates these ecofriendly technologies’ three critical advantages, namely (a) enhanced crop productivity, (b) reduced application of agrochemicals, and (c) increased incomes for farmers. Besides offering an economically attractive and ecologically sound means of augmenting the nutrient supply and combatting soil-borne pathogens, PGPR play an important part in boosting soil fertility, bioremediation and stress management for the development of ecofriendly and sustainable agriculture.

Trends of Applied Microbiology for a Sustainable Economy discusses the role of modern tools and next-generation technologies in applied microbial research, including recent trends and innovation in global biofertilizers. Agriculture has seen dramatic changes since the time of its inception. Starting with the domestication of wild plants to small-scale traditional farming and then large-scale, chemical-intensive agriculture. It is at a crossroads once again, putting a huge amount of pressure on available natural resources like soil, water and biodiversity which is bound to increase with the ever-growing human population. This book helps readers understand the challenges associated with these demographic changes. Redefines the relationship between microorganisms and agricultural sustainability in view of the latest technologies and advancements Documents recent microbiological advancements in agricultural research and discusses challenges and opportunities in the biofertilizers market Identifies challenges and opportunities for scaling up biofertilizers technology Discusses recent trends and innovations in the biotechnology market and economy

There is a scarcity of detailed information regarding the ecophysiology of root systems and the way root system functioning is affected by both internal and external factors. Furthermore, global climate change is expected to increase the intensity of climate extremes, such as severe drought, heat waves and periods of heavy rainfall; in addition other stresses such as salinization of soils are increasing world-wide. Recently an increasing awareness has developed that understanding plant traits will play a major role in breeding of future crop plants. For example, there is increasing evidence that the traits of root systems are defined by the properties of individual roots. However, further knowledge on the functional importance of root segments and the molecular/physiological mechanisms underlying root system functioning and persistence is needed, and would specifically allow modifying (crop) root system functionality and efficiency in the future. Another major gap in knowledge is localized at the root-soil interface and in regard to the potential adaptive plasticity of root-rhizosphere interactions under abiotic stress and/or competition. It is currently unknown whether adaptations in microbe communities occur, for example due to modified exudation rates, and what are the subsequent influences on nutrient mobilization and uptake. Furthermore, uncovering the mechanisms by which roots perceive neighboring roots may not only contribute to our understanding of plant developmental strategies, but also has important implications on the study of competitive interactions in natural communities, and in optimizing plant performance and resource use in agricultural and silvicultural systems. In this Research Topic, we aimed to provide an on-line, open-access snapshot of the current state of the art of the field of root ecology and physiology, with special focus on the translation of root structure to function, and how root systems are influenced by interplay with internal and external factors such as abiotic stress, microbes and plant-plant interaction. We welcomed original research papers, but reviews of specific topics, articles formulating opinions or describing cutting-edge methods were also gladly accepted.

Fungi that inhabit polar-region can grow and decompose organic compounds under subzero temperatures play important roles in the nutrient cycle of polar-region ecosystems. Thus, changes in the mycoflora affect the ecological recycling in these regions, and understanding the cold-adaptation strategies of fungi under extreme environments is critical for a better understanding of polar-region ecosystems. Due to their ability to survive under extreme environments, fungi in polar-region are seen to show potential for utilization in biotechnologies. This book presents our current understanding of the mycoflora in polar-region and their cold adaptation strategies, and applied studies using their abilities.

This book provides information about plant–environment studies and challenges for plant improvement to achieve food security. Plants face a wide range of environmental challenges, which are expected to become more intense as a result of global climate change. Plant–environment interactions play an important role in the functioning of ecosystems. There are habitats throughout the world that present challenges to crop plants, such as through a lack of water and excessive, or toxic, salts in the soil. Soil properties represent a strong selection pressure for plant diversity and influence the structure of plant communities and participate to the generation and maintenance of biodiversity. Plant communities selected by environment grow by modifying soil physical, chemical, and biological properties, with consequent effects on survival and growth of plants. The complexity of plant–environment interactions has recently been studied by developing a trait-based approach in which responses and effects of plants on environment were quantified and modeled. This fundamental research on plant–environment interaction in ecosystems is essential to transpose knowledges of functional ecology to environmental management. Plants have adapted to an incredible range of environment, and extensive researches on ecological and environmental plant physiology have provided mechanistic understanding of the survival, distribution, productivity, and abundance of plant species across the diverse climates of our planet. Ecophysiological techniques have greatly advanced our understanding of photosynthesis, respiration, plant water relations, and plant responses to abiotic and biotic stresses, from instantaneous to evolutionary timescales. Ecophysiological studies also provide the basis for scaling plant physiological processes from the tissue to the canopy, ecosystem, region, and to a large extent, the entire globe. Given the above, the author proposes to bring forth a comprehensive book, “New Frontiers in Plant-Environment Interactions”, highlighting the various emerging techniques and applications that are currently being used in plant–environment interaction research and its future prospects. The author is sure that this book caters the need of all those who are working or have interest in the above topic.
