Re Visiting The Rhizosphere Eco System For Agricultural Sustainability

The present book entitled, “Re-visiting the Rhizosphere Eco-system for Agricultural Sustainability” written by experts in the field, provides a comprehensive and consolidated state-of art overview of various aspects of rhizosphere biology, ecology and functioning. The role of rhizosphere microbial diversity in enhancing plant health and plant-microbe beneficial symbioses is discussed. Main topics include the diversity of plant-associated microbes in the rhizosphere, below-ground communication among the plant, soil, insects and microbes, rhizosphere ecosystem functioning, rhizosphere engineering, recruitment of microorganisms in the rhizosphere, mycorrhizal fungal symbiosis, positive interaction of the plants with the beneficial soil microorganisms for inducing the plant growth, conferring abiotic and biotic stress tolerance and modulating several pathways of the plants for the proper establishment and revitalization in the degraded and contaminated soils or negative likes the host-pathogen interactions leading to the disease development in plants. Further chapters focus on the role of signaling during the different stages of the plant-microbe coexistence, in symbiotic or pathogenic relationships, in quorum sensing, microbial signaling and cross-talk, bio-film formation, and antimicrobial peptides. The book also discusses the application of microbes in biodegradation of xenobiotic contaminants, bioremediation of heavy metals, sustainable agriculture and soil health, biological control of insect pests and plant pathogens, and the latest tools of omics which offer pioneering approaches to the exploration of microbial structure and function, secretome, holobiome, below-ground interaction, and microbial cooperation for sustainable food production and enhanced resource acquisition. Descriptions of cutting-edge techniques and novel approaches make this book unique in the area of rhizosphere biology. This is a useful reading material for researchers and students of microbiology, agriculture, ecology, and rhizosphser studies.

This edited volume is the first book that explicitly explains the link between the extraordinarily small-scale microbial processes and the growth and yield attributes of millet crops. This book includes chapters emphasizing on the effects of rhizosphere biology on long-term millet crop management. Millets are a collection of small-grained cereal grasses that are grown for human carbohydrate needs. They are among the oldest crops, mainly divided into two groups: major and small millets based on seed size. Major millets are composed of sorghum (Sorghum bicolor) and pearl millet (Pennisetum glaucum); while small millets are composed of six species that includes finger millet (Eleusine coracana (L.)), little millet (Panicum sumatrense), kodo millet (Paspalum scrobiculatum (L.)), foxtail millet (Setaria italica (L.)), barnyard millet (Echinochloa frumentacea (L.)), and proso millet (Panicum miliaceum (L.). These crops are earlier considered as orphan crops, but recently due to their nutritional values it is gaining the importance. Various reports are published based on role of rhizosphere on growth and health of these crops. The rhizosphere being a dynamic interface among the plant roots and soil microbes provides a number of advantages to the millets too. The soil properties in rhizospheric region are also different as compared to the bulk soil. This book discovers the functional attributes of rhizosphere in promoting the healthy growth of millet crop and achieving higher yield during the changing climatic condition. This book is of interest to university teachers, scientists working in the millets, and policymakers in agricultural departments. Also, the book serves as additional reading material for undergraduate and graduate students of agriculture, biotechnology, microbiology, genetics, and soil science.

Traditional agricultural practices face escalating environmental challenges and struggle to meet global food demands while ensuring soil health and sustainability. Soil degradation, exacerbated by factors like industrialization and urbanization, significantly threatens crop productivity and food security.

Nanotechnology Applications and Innovations for Improved Soil Health presents a groundbreaking solution to this pressing issue, offering a comprehensive guide to leveraging nanotechnology for sustainable agriculture. This pioneering book explores the transformative potential of nanomaterials in enhancing soil quality and crop production. By harnessing the unique properties of nanomaterials, such as their high surface area and reactivity, researchers and practitioners can develop novel strategies to address soil degradation and improve nutrient availability. By systematically examining nanotechnology's role in soil health, this book equips readers with the knowledge and tools needed to revolutionize agricultural practices and ensure food security for future generations.

In recent decades, agrochemicals have enhanced crop productivity to meet increasing global food requirements. However, prolonged and extensive use of agrochemicals has resulted in contamination that persists in the soil system which can be biomagnified in the food chain. Furthermore, toxic chemicals adversely affect important soil microbial biota, the key drivers of biogeochemical cycles. This concern has raised the need to develop environmentally friendly and cost-effective nano- and micro-biotechnology strategies to minimize the adverse impact of agrochemicals and pesticide residues on soil microbiota, soil fertility, and their biomagnification in food crops. Nano-bioinoculants - the combination of nano-compounds and bioinoculants - have been increasingly used as soil amendments. They can improve agri-potential and soil health by maintaining soil physico- and biological properties, microbial diversity, and the nutrient-solubilizing microbial population. They also aid in improving crop yields and reducing agrochemical and pesticide residues. Nano-bioinoculants are more efficient than other methods for removing contaminants due to their small size, high reactivity, and catalytic activities. Several types of nano-compounds (chitosan, zeolite, gypsum, and silicon dioxide) have been used in conjunction with beneficial microbes (bacteria fungi, actinomycetes & endophytic bacteria) as nano-bioinoculants.

Plants create a dynamic micro-biosphere in the soil, around the roots, called as ‘rhizosphere’, which harbors diverse number of microorganisms for sustaining their growth and development. A soil with diverse and multi-traits microbial communities is considered healthy to enhance crop productivity. In the last decades, rhizosphere biology has gained attention due to unraveling of new mechanisms, processes and molecules in the rhizosphere that contributes towards the promotion of plant productivity. The rhizospheric microbes and associated processes are being utilized for harnessing potential of soils in effective and sustainable functioning in the agro-ecosystems. Broadly, the book discusses rhizospheric microbes and their role in modulating functions of soil and crop plant. Specifically, it highlights conventional and modern aspects of rhizosphere microbes such as – microbiome in the rhizosphere, microbes as an indicator and promoter of soil health, rhizosphere microbes as biofertilizer, biostimulator and biofortifyer, microbial signaling in the rhizosphere, recent tools in deciphering rhizobiome, and regulatory mechanisms for commercialization of biofertilizer, biopesticide and biostimulator. The book is useful for agriculture scientist, biotechnologist, plant pathologist, mycologist, and microbiologist, farming community, scientist of R&D organization, as well as teaching community, researcher and student and policy maker.
