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.

Arbuscular mycorrhiza: a viable strategy for soil nutrient loss reduction
(Springer Verlag, 2019) Manoj Parihar; Vijay Singh Meena; Pankaj Kumar Mishra; Amitava Rakshit; Mahipal Choudhary; Ram Prakash Yadav; Kiran Rana; Jaideep Kumar Bisht
Arbuscular mycorrhiza fungi’s (AMF) role in plant nutrition and stress management is well known, but very few researches and studies have been conducted so far on the fungal ability to reduce different nutrient losses (runoff, leaching and volatilization) from the soil system. This important ecosystem service of AMF had been neglected largely. From the recent findings, it has been confirmed that mycorrhizal symbiosis has potential to check the losses of applied nutrients. The role of soil biota in nutrient cycling is indispensable and determines the nutrient availability to plants. Among these biota, AMF’s association with plants is the most prevalent, but the exact mechanisms followed by AMF in nutrient cycling, transformation and reducing nutrient loss ability are still inconclusive. In this review, we will try to unlock this particular aspect of AMF which is important to achieve global food demand in a sustainable way. © 2019, Springer-Verlag GmbH Germany, part of Springer Nature.

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.

(Elsevier, 2022) Manoj Parihar; Manoj Kumar Chitara; Hanuman Ram; Asha Kumari; Gopal Tiwari; Kiran Rana; Bisweswar Gorain; Utkarsh Kumar; Jaideep Kumar Bisht; Lakshmi Kant
In order to meet the food demands of burgeoning population, innovative and efficient management practices are required for sustainable agricultural production. The high value crops (HVCs) including vegetables, horticulture, fruit and field crops such as potato, cotton, sugarcane etc. not only strengthen the financial security of farmers but also ensure their food, fiber and nutritional availability. To improve the productivity of HVCs, use of beneficial microbial symbionts such as arbuscular mycorrhizal fungi (AMF) is very promising and eco-friendly approach. The AMF form association with most of the land plants including agricultural and HVCs. They provide numerous benefits to the plants including better availability of water and nutrients, alleviate various biotic and abiotic stresses and promote plant growth. However, AMF response in improving the plant performance depends upon several other aspects such as soil environment, AMF strains, plant genotypes, agricultural management practices etc. In this regard, future research must be towards optimization of AMF plant association, suitable inoculum production and application techniques and co-inoculation of AMF with other plant growth promoting bacteria. In the present chapter we will discuss the state-of-the-art of potential of AMF to improve the production of HVCs, its application in micro-propagation program, commercialization and future advancement for sustainable production system. © 2022 Elsevier Inc.

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.
