Agriculturally important microbes for sustainable agriculture
(Springer Singapore, 2017) Vijay Singh Meena; Pankaj Kumar Mishra; Jaideep Kumar Bisht; Arunava Pattanayak
This book presents a compilation of case studies from different countries on achieving agricultural sustainability. The book stresses that, in order to meet the needs of our rapidly growing population, it is imperative to increase agricultural productivity. If global food production is to keep pace with an increasing population, while formulating new food production strategies for developing countries, the great challenge for modern societies is to boost agricultural productivity. Today, the application of chemicals to enhance plant growth or induced resistance in plants is limited due to the negative effects of chemical treatment and the difficulty of determining the optimal concentrations to benefit the plant. In the search for alternative means to solve these problems, biological applications have been extensively studied. Naturally occurring plant-microbe-environment interactions are utilized in many ways to enhance plant productivity. As such, a greater understanding of how plants and microbes coexist and benefit one another can yield new strategies to improve plant productivity in the most sustainable way. Developing sustainable agricultural practices requires understanding both the basic and applied aspects of agriculturally important microorganisms, with a focus on transforming agricultural systems from being nutrient-deficient to nutrient-rich. This work is divided into two volumes, the aim being to provide a comprehensive description and to highlight a holistic approach, respectively. Taken together, the two volumes address the fundamentals, applications, research trends and new prospects of agricultural sustainability. Volume one consists of two sections, with the first addressing the role of microbes in sustainability, and the second exploring beneficial soil microbe interaction in several economically important crops. Section I elucidates various mechanisms and beneficial natural processes that enhance soil fertility and create rhizospheric conditions favourable for high fertility and sustainable soil flora. It examines the mechanism of action and importance of rhizobacteria and mycorrhizal associations in soil. In turn, section II presents selected case studies involving economically important crops. This section explains how agriculturally beneficial microbes have been utilized in sustainable cultivation with high productivity. Sustainable food production without degrading the soil and environmental quality is a major priority throughout the world, making this book a timely addition. It offers a comprehensive collection of information that will benefit students and researchers working in the field of rhizospheric mechanisms, agricultural microbiology, biotechnology, agronomy and sustainable agriculture, as well as policymakers in the area of food security and sustainable agriculture. © Springer Nature Singapore Pte Ltd. 2017.

Beneficial microbes associated with plant roots play an important role to achieve higher agriculture production for burgeoning population in sustainable way. Among various microbes, arbuscular mycorrhizal (AM) fungi interaction with higher land plants is unique as they occupy position both inside and outside of roots. AM fungi as a natural symbionts of land plants provide various ecological services, in particular by improving plant water and nutrition availability, soil health and fertility, alleviating stress condition and wasteland management. Mycorrhizae as a broader group of fungi include seven types of members, i.e. arbuscular, ecto, ectendo, arbutoid, monotropoid, ericoid and orchidaceous, while arbuscular and ectomycorrhizae are the most abundant and ubiquitous. In this chapter, we focus on AM fungi and provide an overview on mycorrhizal interaction, benefits, processes, production development and potential application domain under various conditions. Along with recent advances in AM fungi role under various stress condition, reclamation of problematic wastelands and production aspects, we also discuss about the basic features of AM fungi with past developments to provide an overall glimpse of this plant-fungal interaction. In spite of its growing trends, AM fungi’s current application and market sharing are far below to full potential. Regarding this, current challenges, constraints and strategies for future road map to overcome these problems are also discussed briefly. © Springer Nature Singapore Pte Ltd. 2020.
Plant beneficial rhizospheric microorganism (PBRM) strategies to improve nutrients use efficiency: A review
(Elsevier B.V., 2017) Vijay Singh Meena; Sunita Kumari Meena; Jay Prakash Verma; Ashok Kumar; Abhinav Aeron; Pankaj Kumar Mishra; Jaideep Kumar Bisht; Arunava Pattanayak; Muhammad Naveed; M.L. Dotaniya
Plant beneficial rhizospheric microorganisms (PBRMs) are rhizospheric microbes that are able to colonize rhizosphere and to improve plant growth, development and nutrient use efficiency (NUE) by means of a wide variety of mechanisms like organic matter mineralization, biological control against soil-borne pathogens, biological nitrogen (N) fixation, potassium (K), phosphorous (P) and zinc (Zn) solubilization and root growth promotion. Improved grain production to meet the food demand of an increasing population has been highly dependent on chemical fertilizer input based on the traditionally assumed notion of ‘high input, high output’, which results in overuse of fertilizers but ignores the biological potential of roots or rhizosphere for efficient mobilization and acquisition of soil nutrients. A very interesting feature of PBRMs is their ability of enhancing nutrient bioavailability or NUE by ∼ 20-40% with various nutrients. Although chemical fertilization is a quick method, it is not recommendable economically and environmentally, especially if overused. Several PBRMs species have been characterized as biological N-fixer, P, K-solubilizing microorganisms while other species have been shown to increase the solubility of micronutrients, like those that produce siderophores for iron (Fe) chelation. The enhanced amount of soluble macro- and micronutrients in the close proximity of the soil-root interface has indeed a positive effect on plant nutrition. There is a growing body of evidence that demonstrates the potential of various microbes to enhance plant productivity and yield in cropping systems. However, the molecular mechanisms underlying these phenomena, the signals involved as well as the potential applications in a sustainable agriculture approach, and the biotechnological aspects for possible rhizosphere engineering are still matters of discussion. © 2017 Elsevier B.V.

Plant beneficial rhizobacteria (PBR) is a group of naturally occurring rhizospheric microbes that enhance nutrient availability and induce biotic and abiotic stress tolerance through a wide array of mechanisms to enhance agricultural sustainability. Application of PBR has the potential to reduce worldwide requirement of agricultural chemicals and improve agro-ecological sustainability. The PBR exert their beneficial effects in three major ways; (1) fix atmospheric nitrogen and synthesize specific compounds to promote plant growth, (2) solubilize essential mineral nutrients in soils for plant uptake, and (3) produce antimicrobial substances and induce systemic resistance in host plants to protect them from biotic and abiotic stresses. Application of PBR as suitable inoculants appears to be a viable alternative technology to synthetic fertilizers and pesticides. Furthermore, PBR enhance nutrient and water use efficiency, influence dynamics of mineral recycling, and tolerance of plants to other environmental stresses by improving health of soils. This report provides comprehensive reviews and discusses beneficial effects of PBR on plant and soil health. Considering their multitude of functions to improve plant and soil health, we propose to call the plant growth-promoting bacteria (PGPR) as PBR. © 2019, Springer-Verlag GmbH Germany, part of Springer Nature.
The potential of arbuscular mycorrhizal fungi in C cycling: a review
(Springer Science and Business Media Deutschland GmbH, 2020) Manoj Parihar; Amitava Rakshit; Vijay Singh Meena; Vijai Kumar Gupta; Kiran Rana; Mahipal Choudhary; Gopal Tiwari; Pankaj Kumar Mishra; Arunava Pattanayak; Jaideep Kumar Bisht; Surendra Singh Jatav; Priyanka Khati; Hanuman Singh Jatav
Arbuscular mycorrhizal fungi (AMF) contribute predominantly to soil organic matter by creating a sink demand for plant C and distributing to below-ground hyphal biomass. The extra-radical hyphae along with glomalin-related soil protein significantly influence the soil carbon dynamics through their larger extent and turnover period need to discuss. The role of AMF is largely overlooked in terrestrial C cycling and climate change models despite their greater involvement in net primary productivity augmentation and further accumulation of this additional photosynthetic fixed C in the soil. However, this buffering mechanism against elevated CO2 condition to sequester extra C by AMF can be described only after considering their potential interaction with other microbes and associated mineral nutrients such as nitrogen cycling. In this article, we try to review the potential of AMF in C sequestration paving the way towards a better understanding of possible AMF mechanism by which C balance between biosphere and atmosphere can be moved forward in more positive direction. © 2020, Springer-Verlag GmbH Germany, part of Springer Nature.
