“…These rhizobacteria are known as effective disease-fighters, helping agricultural productivity and sustainability (Bhat et al, 2022;Gamalero and Glick, 2022;Gowtham et al, 2022). The PGPR that flourishes in the rhizosphere improves plant growth by various mechanisms, such as nitrogen fixation, production of phytohormones, 1-aminocyclopropane-1-carboxylate (ACC) deaminase (Sagar et al, 2020), exopolysaccharides (EPS; Sayyed et al, 2015Sayyed et al, , 2019Ilyas et al, 2020), siderophores (Nithyapriya et al, 2021;Srivastava et al, 2022), antioxidants (Gowtham et al, 2022), osmoprotectants (Ilyas et al, 2020), nutrient uptake (Jabborova et al, 2020(Jabborova et al, , 2022Deepranjan et al, 2021;Kapadia et al, 2021;Sarkar et al, 2021), and induced systemic resistance (ISR; Reshma et al, 2018;Desai et al, 2023) in stressful conditions. These PGPR can also influence plant metabolism and gene expression directly, as well as the expression of root proteins, root morphology, and root growth (Vacheron et al, 2013;Kalam et al, 2020;Basu et al, 2021;Hamid et al, 2021;Ahmad et al, 2022;Lobhi et al, 2022).…”

The present crisis at hand revolves around the need to enhance plant resilience to various environmental stresses, including abiotic and biotic stresses, to ensure sustainable agriculture and mitigate the impact of climate change on crop production. One such promising approach is the utilization of plant growth-promoting rhizobacteria (PGPR) to mediate plant resilience to these stresses. Plants are constantly exposed to various stress factors, such as drought, salinity, pathogens, and nutrient deficiencies, which can significantly reduce crop yield and quality. The PGPR are beneficial microbes that reside in the rhizosphere of plants and have been shown to positively influence plant growth and stress tolerance through various mechanisms, including nutrient solubilization, phytohormone production, and induction of systemic resistance. The review comprehensively examines the various mechanisms through which PGPR promotes plant resilience, including nutrient acquisition, hormonal regulation, and defense induction, focusing on recent research findings. The advancements made in the field of PGPR-mediated resilience through multi-omics approaches (viz., genomics, transcriptomics, proteomics, and metabolomics) to unravel the intricate interactions between PGPR and plants have been discussed including their molecular pathways involved in stress tolerance. Besides, the review also emphasizes the importance of continued research and implementation of PGPR-based strategies to address the pressing challenges facing global food security including commercialization of PGPR-based bio-formulations for sustainable agricultural.

A majority of agricultural activities are conducted under fragile lands or set-up. The growth and development of crops are negatively affected due to several biotic and abiotic stresses. In the current situation, research efforts have been diverted toward the short-term approaches that can improve crop performance under changing environments. Seed treatment or priming technology is in a transition phase of its popularity among resource-poor farmers. Suitable policy intervention can boost low-cost techniques to implement them on a larger scale in developing countries and to harness the maximum benefits of sustainable food production systems. Primed seeds have high vigor and germination rate that help in seedling growth and successful crop stand establishment under stress conditions. This review is attempted to assess different seed priming techniques in terms of resource use efficiency, crop productivity, cost–benefit balance, and environmental impacts. Moreover, a comprehensive study of the mechanisms (physiological and biochemical) of seed priming is also elaborated. A detailed examination of the applications of priming technology under diverse agroecosystems can improve our understanding of the adaptive management of natural resources.

“…Although genetic engineering strategies hold promise for the discovery, mutation, and de novo design [4,5] of catalysts with high stability and bioactivity, chemical modification. Immobilization imparts enzymes with unique catalytic properties for practical exploitation, such as improved biocatalytic performance, mechanical strength, aggrandized stability, and repeated useability [6,7]. In addition, providing a distinct microenvironment to the enzymes is a noteworthy characteristic of immobilization.…”

“…In addition, providing a distinct microenvironment to the enzymes is a noteworthy characteristic of immobilization. Furthermore, engineering a biocompatible microenvironment for catalysts is valuable for optimizing enzyme-catalyzed reactions [6]. The microenvironment is the micro-and nanoscale local physicochemical atmosphere surrounding the enzyme molecules or a cluster of enzymes at their catalytic region.…”

The rational design of catalysts that fine-tune/mimics the enzyme microenvironment remains the subject of supreme interest. Several strategies moving from traditional to 2 technologically advanced methods have been proposed and deployed to develop high efficacy enzymes. There is a plethora of literature on simple enzyme immobilization through different materials as support carriers, even at the micro-and nanoscale.Regardless of extensive strategic efforts, the existing literature lacks deep insight into tailoring the microenvironment surrounding the target enzyme molecules and can sophisticatedly integrate the bio-catalysis for multipurpose applications. The ongoing advancement in the industrial sector also demands catalysts with unique features. For instance, catalytic turnover, substrate affinity, stability, specificity, selectivity, resistivity against reaction impurities or inhibitors, prevention of subunit dissociation, ease in recovery, and reusability are highly requisite features. This review spotlight state-of-theart protein engineering approaches that facilitate the redesigning of robust catalysts or fine-tuning the catalytic microenvironment of enzymes. The entire work critically focuses on protein engineering approaches, i.e., regulating pH microenvironment, creating a water-like microenvironment, activating enzyme catalysis in organic solvents and gas phase, tuning reaction kinetics (KM and kcat), engineering substrate specificity, reaction promiscuity, computational design, and structure-guided biocatalyst engineering. This study unveils the advanced insights of enzyme microenvironment engineering, which can also be considered catalytic yield enhancement strategies to green the future biocatalysis research for industrial bioprocesses.
