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.

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.

Background: Recently, the COVID-19 spread has been drastically increasing worldwide at a breakneck pace. It has resulted in an unparalleled trial in education. Mostly, all educational institutes have announced their closure to adhere to the government guidelines and have adopted the online learning and teaching mechanism. To look at the optimistic side of this epidemic, we see that people have come up with advanced skills and technologies, new modes of learning, contemporary perspectives, and countless new trends to provide seamless educational services even during this crisis for a better tomorrow. Objective: Survey school and college students after online education and adhere to the government guide-lines. Methods: We directed questionnaires and conducted surveys by 4 members using online mode by Google form, and the data were analysed using mean and percentage. Results: This survey started on 1st June 2021. During the lockdown period, most students responded through online mode, while some gave their responses in off-line mode, which effectively limited the research. Students are more likely to be interested in self-study than virtual studies. During virtual study hours, which schools and colleges provide, students use social media on different tabs and pay the least attention to what is tutored. However, due to online exams, they have access to all websites and even their books, so there is a lesser drop in their grades, making them believe in more unrealistic things in life. Students learn to become dishonest, but some parents continue supporting them in their treacherous behavior just for the sake of grades. Therefore, the major belief of students is that online exams are useless. Scarcely any learner who gives an honest exam gets intimidated as the results are biased and hence em-braces the pathway of bypass. However, amidst all of these, post-COVID-19 currents may allow us to visualize new learning techniques in India and make people more aware of the foreseeable future. In this research, we include school as well as college students. We have received 3120 responses from students. Conclusion: This article discusses that during the COVID-19 crisis, students adopted the learning mode and what is the impact of COVID-19 on the education system. � 2022 Bentham Science Publishers.

Enhanced protection of tomato against Fusarium wilt through biopriming with Trichoderma harzianum
(Elsevier B.V., 2022-11-25T00:00:00) Zehra, Andleeb; Aamir, Mohd; Dubey, Manish K.; Akhtar Ansari, Waquar; Meena, Mukesh; Swapnil, Prashant; Upadhyay, R.S.; Ajmal Ali, Mohammad; Ahmed Al-Ghamdi, Abdullah; Lee, Joongku
Objective: Microbial priming represents an adaptive strategy to enhance the plant defense against subsequent challenges incited by pathogenic microbes. The aim of the study was to investigate the effect of priming with Trichoderma harzianum (Th) on the induced resistance potential of tomato after challenged with Fusarium oxysporum f. sp. lycopersici (Fol) pathogen. Methods: This work demonstrated antioxidative and defense related enzyme activities and qRT-PCR to study the resistance mechanisms of tomato plants bioprimed with T. harzianum against Fol pathogen. Result: Microbial biopriming with T. harzianum resulted into enhanced expression of tomato defense-related genes and was accompanied by increased antioxidative enzymic activities. The study reported that the T. harzianum primed plants showed 2.71-fold higher SOD than control and 1.34-fold (Fol + Th) higher SOD activity compared to Fol challenged plants. In contrast, Fol + Th treated showed 5.87-fold and 1.34-fold higher CAT enzyme activity as compared to control and pathogen exposed plants. T. harzianum bioprimed plants noted 1.47- and 11.47-fold enhanced PPO activity as compared to Fol challenged and controls, respectively. PAL and PO activities were also found higher in T. harzianum primed plants. The qRT-PCR revealed that expression of defense related gene showed higher up-regulation in T. harzianum primed plants as compared to pathogen challenged plants. As compared to control, Fol + Th treated plants also showed higher up-regulation of all the studied genes. Conclusion: The study concluded T. harzianum priming aggravates the plant defense system against the Fol challenged condition and accompanied by higher expression of defense related genes and increased antioxidative activities against subsequent Fol attack. � 2022 The Authors

Nowadays, microorganisms can be used to eliminate a variety of pollutants such as toxic metal ions from wastewater. These emergences of harmful elements in wastewater, high-priced cultivation of microbes and technical hitches in industrial scale production appeared as main challenges for thriving coupling of microbes with wastewater. These microbes serve as potential sorbents by following suitable adsorption mechanisms. There are some photobioreactors have been also mentioned in this review which is based on microbial biofilm and emerged as an alternative technology to predictable photosynthetic systems for treatment of wastewater based on biomass production at low cost. Bioremediation using different microbes showed contrast results to remove heavy metals from wastewater. Microorganism such as Nostoc sp., Aspergillus versicolor, Aspergillus lentulus and Aspergillus niger remediate 99.6, 99.89, 99.7 and 98 % of Pb, Cr, Cu and Ni, respectively. In this review, mechanistic approaches and distinct pathways of the microbes for removal of various inorganic and organic compounds from wastewater have been methodically discussed. We have also discussed some major commercial production challenges such as techno-economic feasibility genetic engineering research and biorefinery approach. Overall the review discussed the microbial biodiversity in wastewater and their role in remediation of wastewater and their ability to be a potent candidate headed for sustainable industrial wastewater treatment applications through different approaches such as phytoremediation and bioremediation. This article provides valuable insights into multiple aspects of environmental biotechnology, including photobioreactors, metal uptake capacity of microorganisms, heavy metal contamination and its effects and bioremediation using molecular approaches and wastewater treatment through phytoremediation. Moreover, it contributes to our understanding of these topics and can help in the development of sustainable solutions for environmental remediation and pollution control in wastewater though microorganisms. � 2023 Elsevier Ltd

Immune signaling networks in plant-pathogen interactions
(Elsevier, 2023-04-21T00:00:00) Zehra, Andleeb; Meena, Mukesh; Swapnil, Prashant
Plants and their pathogens are in a constant coevolutionary fight for dominance. The consequences of these interactions are particularly important for human activities as they may have significant implications for agricultural systems. Plants use a number of cell-surface and intracellular immunological receptors to detect and respond to a variety of immunogenic signals associated with pathogen infection. Plants have a remarkable ability to identify pathogens using both conserved and varied pathogen elicitors, and modify the defense response by secreting virulence effector chemicals. The recent confluence of molecular studies of plant immunity and pathogen invasion tactics has revealed a more comprehensive picture of the plant-pathogen relationship from the perspective of both species. Here, we review the activation of different immune receptors and outline our current understanding of their signaling pathways. We also go over how different receptors are grouped into networks and what this means for the integration of complicated threat signals into appropriate defense outputs. � 2023 Elsevier Inc.

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.

Plant Growth-Promoting Rhizobacteria (PGPR): Approaches to Alleviate Abiotic Stresses for Enhancement of Growth and Development of Medicinal Plants
(MDPI, 2022-11-22T00:00:00) Kumar, Rahul; Swapnil, Prashant; Meena, Mukesh; Selpair, Shweta; Yadav, Bal Govind
Plants are constantly exposed to both biotic and abiotic stresses which limit their growth and development and reduce productivity. In order to tolerate them, plants initiate a multitude of stress-specific responses which modulate different physiological, molecular and cellular mechanisms. However, many times the natural methods employed by plants for overcoming the stresses are not sufficient and require external assistance from the rhizosphere. The microbial community in the rhizosphere (known as the rhizomicrobiome) undergoes intraspecific as well as interspecific interaction and signaling. The rhizomicrobiome, as biostimulants, play a pivotal role in stimulating the growth of plants and providing resilience against abiotic stress. Such rhizobacteria which promote the development of plants and increase their yield and immunity are known as PGPR (plant growth promoting rhizobacteria). On the basis of contact, they are classified into two categories, extracellular (in soil around root, root surface and cellular space) and intracellular (nitrogen-fixing bacteria). They show their effects on plant growth directly (i.e., in absence of pathogens) or indirectly. Generally, they make their niche in concentrated form around roots, as the latter exude several nutrients, such as amino acids, lipids, proteins, etc. Rhizobacteria build a special symbiotic relationship with the plant or a section of the plant�s inner tissues. There are free-living PGPRs with the potential to work as biofertilizers. Additionally, studies show that PGPRs can ameliorate the effect of abiotic stresses and help in enhanced growth and development of plants producing therapeutically important compounds. This review focuses on the various mechanisms which are employed by PGPRs to mitigate the effect of different stresses in medicinal plants and enhance tolerance against these stress conditions. � 2022 by the authors.
