    Advantageous features of plant growth-promoting microorganisms to improve plant growth in difficult conditions
    (Elsevier, 2023-04-21T00:00:00) Meena, Mukesh; Yadav, Garima; Sonigra, Priyankaraj; Nagda, Adhishree; Mehta, Tushar; Swapnil, Prashant; Marwal, Avinash; Zehra, Andleeb
    Microbes play a fundamental role in plant growth and development. The valuable microbes, also known as plant growth-promoting microorganisms (PGPMs) belong to different groups such as fungi, bacteria, and archaea which are connected with plants in rhizospheric, epiphytic, and endophytic forms. These microorganisms display a group of function to promote plant growth such as phytohormone (auxin and gibberellin) production enhancement, siderophore production, micronutrient solubilization (P, K, Fe, and Zn), N2 fixation, antibiotic production, etc. Apart from growth promotion, PGPMs also confer stress and disease tolerance to plants for controlled agricultural production in harsh environmental conditions. PGPMs have the capability to induce systemic resistance (ISR) in crops against pathogen attack. To date, a huge number of microbial species have been documented for their plant growth-promoting ability. Generally, crops fail to provide adequate concentration of micronutrients in the human diet and cause micronutrient malnutrition and severe health complications. Considering all these points, PGPMs are utilized as biofertilizers to increase vigor and the nutrient value of crop plants at varied habitats. The present chapter is intended to focus the ability of PGPMs to perk up the plant growth in difficult conditions. � 2023 Elsevier Inc. All rights reserved.

    Plant-Microbe Interaction - Recent Advances in Molecular and Biochemical Approaches: Volume 1: Overview of Biochemical and Physiological Alteration During Plant-Microbe Interaction
    (Elsevier, 2023-04-21T00:00:00) Swapnil, Prashant; Meena, Mukesh; Harish; Marwal, Avinash; Vijayalakshmi, Selvakumar; Zehra, Andleeb
    Plant-Microbe Interaction - Recent Advances in Molecular and Biochemical Approaches: Overview of Biochemical and Physiological Alteration During Plant-Microbe Interaction, Volume One covers the role of these plant microbes and their interaction between plants and microbes. These beneficial microbes, such as bacteria and fungi are also known as plant growth-promoting rhizobacteria (PGPR) through a biochemical reaction that may improve induced systemic resistance in the plant host via indirectly (against phytopathogens) or directly (the solubilization of mineral nutrients) by producing phytohormones and specific enzymes such as 1-aminocyclopropane-1-carboxylate deaminase.� The book covers biochemical processes such as physiological, metabolic, etc. of plant and microbe interactions, the biochemistry of biological systems, the interaction of biological systems above-ground or within the rhizosphere, and the history of growth promoting microbiomes, their roles in phytoremediation efficiency, physiological and biochemical studies, chemical communication and signaling mechanisms. � 2023 Elsevier Inc.

    Biofilm matrix proteins
    (Elsevier, 2023-01-19T00:00:00) Sharma, Surbhi; Meena, Mukesh; Marwal, Avinash; Swapnil, Prashant
    Biofilms are aggregates of diverse communities of microorganisms that are attached to living or inert surfaces. Microorganisms attach irreversibly to various surfaces and produce many extracellular polymers, which facilitate their growth, resulting in a matrix formation. The extracellular components, which make up the biofilm matrix, are primarily composed of water, proteins, nucleic acids, lipids, exopolysaccharides, and various other biopolymers that can vary depending on the microorganisms and different growth conditions. Matrix proteins play a vital role in the structure and stability of biofilm. The integrity of cells attached to biofilm is regulated by extracellular proteins, which supply nutrients and support the growth of microorganisms. In this chapter, we discuss biofilm composition and the function of proteins in the extracellular matrix. � 2022 Elsevier Inc. All rights reserved.

    Role of elicitors to initiate the induction of systemic resistance in plants to biotic stress
    (Elsevier B.V., 2022-06-30T00:00:00) Meena, Mukesh; Yadav, Garima; Sonigra, Priyankaraj; Nagda, Adhishree; Mehta, Tushar; Swapnil, Prashant; Harish; Marwal, Avinash
    Biotic stress affects crop yield and production. It is essential to acquire the knowledge necessary for designing resistance in host plants by understanding the interaction between pathogens and the host. Salicylic acid and jasmonic acid are principal regulators of interconnected signaling pathways of plant defense mechanisms to overcome stress conditions. Plants on pathogen attack experience transient increase in the reactive oxygen species production which in turn activates local programmed cell death and confers systemic resistance. Disease management is largely done by chemical compounds like fungicides, insecticides, and herbicides. However, these chemicals are hazardous to the environment and living beings hence it is necessary to search for novel harmless means of disease control. Elicitors are molecules that initiate systemic acquired resistance or induced systemic resistance in the host by inducing the expression of pathogenesis-related genes and protecting plants from diseases. This review discusses biotic stress, elicitors, and elicitor-receptor mediated defense mechanism acquired for systemic resistance and in this context, it attempts to draw the attention of the researchers to find novel elicitors as disease control alternatives. � 2022

    Multifarious Responses of Forest Soil Microbial Community Toward Climate Change
    (Springer, 2022-06-03T00:00:00) Meena, Mukesh; Yadav, Garima; Sonigra, Priyankaraj; Nagda, Adhishree; Mehta, Tushar; Swapnil, Prashant; Harish; Marwal, Avinash; Kumar, Sumit
    Forest soils are a pressing subject of worldwide research owing to the several roles of forests such as carbon sinks. Currently, the living soil ecosystem has become dreadful as a consequence of several anthropogenic activities including climate change. Climate change continues to transform the living soil ecosystem as well as the soil microbiome of planet Earth. The majority of studies have aimed to decipher the role of forest soil bacteria and fungi to understand and predict the impact of climate change on soil microbiome community structure and their ecosystem in the environment. In forest soils, microorganisms live in diverse habitats with specific behavior, comprising bulk soil, rhizosphere, litter, and deadwood habitats, where their communities are influenced by biotic interactions and nutrient accessibility. Soil microbiome also drives multiple crucial steps in the nutrient biogeochemical cycles (carbon, nitrogen, phosphorous, and sulfur cycles). Soil microbes help in the nitrogen cycle through nitrogen fixation during the nitrogen cycle and maintain the concentration of nitrogen in the atmosphere. Soil microorganisms in forest soils respond to various effects of climate change, for instance, global warming, elevated level of CO2, drought, anthropogenic nitrogen deposition, increased precipitation, and flood. As the major burning issue of the globe, researchers are facing the major challenges to study soil microbiome. This review sheds light on the current scenario of knowledge about the effect of climate change on living soil ecosystems in various climate-sensitive soil ecosystems and the consequences for vegetation-soil-climate feedbacks. � 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
