Global warming and its effect on soil health are a potential threat to global agriculture with regard providing ecosystem services the ever-growing population. Climate change-induced degradation subsequent crop loss lead unfavorable effects food security economic issues, besides resulting in competition for available land resources. Though research efforts toward protecting through several integrated approaches such as conservation agriculture, organic farming, nutrient, water, pest disease management place, targeted yield future population may not be achieved. The world still largely depends chemical agri-inputs achieve targets, which long run deteriorate health. Recent developments molecular technology have resulted innovative technologies, including breeding of climate-resilient crops or development stress-tolerant using genetic modifications; technologies take time reach farmers due environmental policies consumer consciousness. Hence, attention needs also focus use bioinoculants microbial stabilize productivity. literature survey illustrates promise microorganisms, help mitigate climate harmful plants.

Phosphorus (P) is an important nutrient for plants, and a lack of available P greatly limits plant growth development. Phosphate-solubilizing microorganisms (PSMs) significantly enhance the ability plants to absorb utilize P, which improving turnover yield. This article summarizes analyzes how PSMs promote absorption utilization nutrients by from four perspectives: types functions PSMs, phosphate-solubilizing mechanisms, main functional genes, impact complex inoculation on acquisition. reviews physiological molecular mechanisms phosphorus solubilization promotion with focus analyzing soil microbial communities its interaction root exudates. In order better understand their role in transformation provide prospects research promoting absorption. mainly activate insoluble through secretion organic acids, phosphatase production, mycorrhizal symbiosis, symbiosis indirectly activates via carbon exchange. can secrete acids produce phosphatase, plays crucial cycling, related genes are involved regulating P-solubilization ability. uptake great significance deeper understanding PSM-mediated utilization, efficiency agriculture.

Drought stress hampers plant growth and productivity. Some microorganisms mitigate in plants; however, the molecular mechanism by which they interact with plants mitigating remains unknown. This study aimed to determine growth–promoting rhizobacteria modulate drought soybean. Results indicated that B. pumilus SH-9 (SH-9) produced indole acetic acid siderophore, had capacity for phosphate solubilization. The test polyethylene glycol 6000 (PEG) tolerance, showed could withstand high PEG concentration (up 30%). isolate was identified a strain using 16s ribosomal DNA gene sequence. Inoculation of soybeans enhanced soybean biomass 20%, even under stress. due reduction endogenous phytohormone (abscisic acid) upregulation antioxidant defense system (SOD, POD, APX, GSH) SH-9. Furthermore, transcription factors GmDREB2, GmbZIP1, GmNCED3 were involved. also improved physio-morphological characteristics such as biomass, chlorophyll, seedling length, relative water contents stressed plant. Overall, findings this enhances promoting solubilization, exopolysaccharides. We, therefore, conclude is drought-tolerant variant can improve via modulation expression gene, profile.

Chemicals are used extensively in agriculture to increase crop production meet the nutritional needs of an expanding world population. However, their injudicious application adversely affects soil's physical, chemical and biological properties, subsequently posing a substantial threat human health global food security. Beneficial microorganisms improve plant productivity with minimal impact on environment; however, efficacy greatly relies technique. Biopriming is advantageous technique that involves treatment seeds beneficial agents. It exhibits immense potential improving physiological functioning seeds, thereby playing pivotal role uniform germination vigor. Biopriming-mediated molecular metabolic reprogramming imparts stress tolerance plants, improves health, enhances productivity. Furthermore, it also associated rehabilitating degraded land, soil fertility, nutrient cycling. Although biopriming has vast applications agricultural system, its commercialization utilization by farmers still infancy. This review aims critically analyze recent studies based biopriming-mediated mitigation alteration physiological, processes plants. Additionally, considering necessity popularizing this technique, major challenges prospects linked systems have been discussed. © 2023 Society Chemical Industry.

Phytohormones play vital roles in stress modulation and enhancing the growth of plants. They interact with one another to produce programmed signaling responses by regulating gene expression. Environmental stress, including drought hampers food energy security. Drought is abiotic that negatively affects productivity crops. Abscisic acid (ABA) acts as a prime controller during an acute transient response leads stomatal closure. Under long-term conditions, ABA interacts other hormones, such jasmonic (JA), gibberellins (GAs), salicylic (SA), brassinosteroids (BRs), promote closure genetic Regarding antagonistic approaches, cytokinins (CK) auxins (IAA) regulate opening. Exogenous application phytohormone enhances tolerance soybean. Thus, phytohormone-producing microbes have received considerable attention from researchers owing their ability enhance drought-stress biological processes The present study was conducted summarize role phytohormones (exogenous endogenous) corresponding model plant A total n=137 relevant studies were collected reviewed using different research databases.
