Modern intensive agricultural practices face numerous challenges that pose major threats to global food security. In order address the nutritional requirements of ever-increasing world population, chemical fertilizers and pesticides are applied on large scale increase crop production. However, injudicious use agrochemicals has resulted in environmental pollution leading public health hazards. Moreover, agriculture soils continuously losing their quality physical properties as well (imbalance nutrients) biological health. Plant-associated microbes with plant growth- promoting traits have enormous potential solve these play a crucial role enhancing biomass yield. The beneficial mechanisms growth improvement include enhanced nutrient availability, phytohormone modulation, biocontrol phytopathogens amelioration biotic abiotic stresses. Solid-based or liquid bioinoculant formulation comprises inoculum preparation, addition cell protectants such glycerol, lactose, starch, good carrier material, proper packaging best delivery methods.

Abstract Globally, substantial research into endophytic microbes is being conducted to increase agricultural and environmental sustainability. Endophytic such as bacteria, actinomycetes, fungi inhabit ubiquitously within the tissues of all plant species without causing any harm or disease. Endophytes form symbiotic relationships with diverse can regulate numerous host functions, including resistance abiotic biotic stresses, growth development, stimulating immune systems. Moreover, endophytes play a dominant role in nutrient cycling, biodegradation, bioremediation, are widely used many industries. have stronger predisposition for enhancing mineral metal solubility by cells through secretion organic acids low molecular weight metal-specific ligands (such siderophores) that alter soil pH boost binding activity. Finally, synthesize various bioactive compounds high competence promising candidates new drugs, antibiotics, medicines. Bioprospecting novel secondary metabolites has given momentum sustainable agriculture combating stresses. Biotechnological interventions aid played pivotal crop improvement mitigate stress conditions like drought, salinity, xenobiotic compounds, heavy metals. Identification putative genes from conferring tolerance diseases, apart those involved accumulation degradation contaminants, could open avenues development. Furthermore, detailed biochemical understanding endophyte entry colonization strategy would better help manipulating productivity under changing climatic conditions. Therefore, present review highlights current trends based on SCOPUS database, potential biotechnological microorganisms stresses influencing productivity, future opportunities improving tolerance, their contribution remediation hazardous contaminants.

Abiotic stresses are the most significant factors reducing agricultural productivity. Plants face extreme environmental conditions that may affect their biological mechanisms, thereby influencing growth and development. Microorganisms possess substantial metabolites aid in helping plants mitigate abiotic stresses. Plants’ interaction with microbes constitutes a diversified ecosystem, as sometimes both partners share mutualistic relationship. Endophytes, plant-growth-promoting rhizobacteria (PGPRs), arbuscular mycorrhizal fungi (AMFs) examples of microorganisms play an essential role alleviating and, hence, improving plant growth. The plant–microbe leads to modulation complex mechanisms cellular system. Moreover, residing microbial flora also inhibits phytopathogens, therefore, it becomes part plants’ innate defense Keeping view growing concerns, is important identify microbiome transportation nutrients maintain sustainable production. Furthermore, enabling recruit beneficial species how deal potential pathogens. Therefore, this review aims summarize impacts various stressors on productivity mitigating negative effects literature shows microbes, including PGPRs, AMFs, endophytes, adopt for ameliorating It has been observed biochar either individually or combination, can maintaining under stress conditions. Although conventional inoculation mitigates enhances productivity, advancement genetic engineering would help transfer specific genes from mitigation.

Plant growth-promoting bacteria (PGPB) enhance plant growth, as well protect plants from several biotic and abiotic stresses through a variety of mechanisms. Therefore, the exploitation PGPB in agriculture is feasible it offers sustainable eco-friendly approaches to maintaining soil health while increasing crop productivity. The vital key application its effectiveness colonizing roots phyllosphere, developing protective umbrella formation microcolonies biofilms. Biofilms offer benefits PGPB, such enhancing resistance adverse environmental conditions, protecting against pathogens, improving acquisition nutrients released environment, facilitating beneficial bacteria–plant interactions. bacterial biofilms can successfully compete with other microorganisms found on surfaces. In addition, plant-associated are capable colonization sites, cycling nutrients, pathogen defenses, tolerance stresses, thereby agricultural productivity yields. This review highlights role surfaces strategies used by biofilm-forming PGPB. Moreover, factors influencing biofilm at root shoot interfaces critically discussed. will pave formulations addressing challenges related their efficacy competence for sustainability.

Plant microbiome (or phytomicrobiome) engineering (PME) is an anticipated untapped alternative strategy that could be exploited for plant growth, health and productivity under different environmental conditions. It has been proven the phytomicrobiome crucial contributions to health, pathogen control tolerance drastic (a)biotic constraints. Consistent with safety, in this article we address fundamental role of its insights productivity. We also explore potential restrictions proposition improving microbial functions can supportive better growth production. Understanding associated communities, propose how actions enhanced improve growth-promoting mechanisms, a particular emphasis on beneficial fungi. Additionally, suggest possible strategies adapt harsh environment by manipulating microbiomes. However, our current understanding still infancy, major perturbations, such as anthropocentric actions, are not fully understood. Therefore, work highlights importance create more sustainable agriculture, particularly stressors.

Crop productivity and yield are adversely affected by the deficiency of P in agricultural soil. Phosphate fertilizers used at a large scale to improve crop yields globally. With rapid increase human population, food demands also increasing. To see that meet demands, farmers have continuously added phosphate their arable fields. As primary source inorganic phosphorous, rock is finite risk its being jeopardized foreseeable future high. Therefore, there dire need plant-available soil, using feasible, environmentally friendly technologies developed on basis further understanding dynamics between soil plants. This study systemically reviews mechanism uptake P-use efficiency plants under starvation conditions. The recent advances various strategies, especially imaging techniques, over period 2012–2021 for measurement identified. then examines how fulfill requirements from tissue-stored during starvation. Following this understanding, strategies increasing evaluated. Finally, an update novel carriers content provided.
