(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 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.

Exponential upsurge in the global population growth rate claims sustainable means to fulfill their food requirements. Therefore, the collaboration of beneficial microorganisms with their host plants have been of interest for years as these associations can be helpful in the development of sustainable agriculture. However, the endophytic microorganisms develop a strong and persistent interaction with the host plants compared to epiphytic microbes. The origin of plant-associated endophytes was supposed to be from seeds as the endophytic microbes were found inside seeds of several plant species although, endophytes do not necessarily come from seeds only but can also enter the roots or other parts during plant growth. In any case, the richness of seed with the microbes and their dynamics can edify innovative research potentials in the field of plant-microbe associations. Yet, the seed microbiome is often underrepresented in plant microbial studies and is least studied up till now compared to phyllospheric or rhizospheric microbial population. The revival of exploring the seed microbiome is stimulating new insights related to the dynamics and diversity of seed microbiome along with their interconnectedness with the soil and plant microbial community as well as the microbes associated with pollinators and dispersers. This review is an effort to acknowledge the research on seed associated microbial community including bacteria and fungi. It focuses on ecology of seed microbiome from sources to diversity, their association with the host plant, and their life cycle including mode of colonization, localization, and transmission. Both the horizontal and vertical means of transmission have been discussed in this paper whereas the significance of vertical transmission for rapid infection of beneficial microbial community to next generations of plants through seeds is emphasized. Moreover, the applications of seed endophytes for growth promotion of plants, as biocontrol agents and in phytoremediation are discussed. Finally, the association of seed endophytes with seed quality is linked. © 2021
The potential of arbuscular mycorrhizal fungi in C cycling: a review

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.
