The use of plant growth-promoting bacteria (PGPB) is a promising approach to improving crop nutrient management. This study used multiple biological indicators identify efficient PGPB strains and investigate their impacts on soil dynamics, growth, uptake during the critical growth stages Zea mays. Two high-performing were selected based phosphate solubilization growth-promotion potential. Pot experiments revealed that these enhanced characteristics significantly, including organic matter, alkaline-hydrolyzable N, available K, thereby availability. In Z. mays, increased total root length, diameter, number tips markedly, expanding system's absorption capacity. Without phosphorus (P) fertilizer, nitrogen efficiency (NUE) potassium (KUE) by up 34% 25.43%, respectively, compared control. With P maximum increases 65.37% 33.33%. absence combined inoculation more than single (T1, T2), with NUE increasing 14.04% 10.29%, KUE 9.61% 7.35%, respectively. Both inoculations effectively mays architecture activated essential nutrients, highlighting potential in sustainable improve management productivity. © 2025 Society Chemical Industry.

Unveiling the Thermotolerance and Growth-Promoting Attributes of Endophytic Bacteria Derived from Oryza sativa: Implications for Sustainable Agriculture

Microorganisms, Год журнала: 2025, Номер 13(4), С. 766 - 766

High temperatures pose significant challenges to rice plants’ growth and their associated endophytic bacteria. Understanding how these bacteria respond heat stress is vital. We assessed the potential of five bacterial strains derived from Oryza sativa—Bacillus tequilensis LB3, B. coagulans LB6, paralicheniformis AS9, pumilus LB16, paranthracis i40C—to mitigate effects on plants. These demonstrated robust abilities in producing indole-3-acetic acid (IAA) siderophores, nitrogen fixation, solubilization phosphate potassium. Under high-temperature conditions, they significantly enhanced plant growth, with increases length up 78% at 40 °C. Notably, LB6 showed highest biomass increase (195%). The also improved chlorophyll SPAD values, an indicator reduced health. Phytohormone profiling biochemical analyses revealed abscisic (ABA) levels, lipid peroxidation (MDA), elevated osmoprotectant proline accumulation under stress. Inoculated plants exhibited 539 ng g−1 ABA (vs. 62 uninoculated controls), a 68% reduction MDA (indicating less oxidative damage), synthesis, collectively suggesting adaptation. changes were linked IAA production nutrient modulation, which alleviated heat-induced physiological decline. findings underscore endophytes as biofertilizers improve resilience Among strains, superior performance, offering greatest promise for heat-stress mitigation production. This study advances our understanding phytohormonal, signaling, chemical processes underlying bacterial-mediated thermotolerance, providing foundation sustainable agricultural strategies. Future research can explore morphological analyses, stress-responsive gene expression (e.g., HSPs, DREBs, APX) combined selected fertilizers cultivation.
