Mowing significantly influences nutrient cycling and stimulates metabolic adjustments in plants to promote regrowth. Plant growth-promoting rhizobacteria (PGPR) are crucial for enhancing plant growth, absorption, stress resilience; however, whether inoculation with PGPR after mowing can enhance regrowth capacity further, as well its specific regulatory mechanisms, remains unexplored. In this study, Pantoea eucalyptus (B13) was inoculated into mowed Leymus chinensis evaluate effects on phenotypic traits, root contents, hormone levels during the process further explore role of L. mowing. The results showed that mowing, sugar contents decreased significantly, while signal pathways related hormones were activated. This indicates resources tend sacrifice a part growth prioritize defense. After B13 regulated plant's internal balance by reducing JA, SA, ABA upregulated transduction root, thus optimizing defense environment. Transcriptomic metabolomic analyses indicated promoted uptake transport maintained homeostasis, enhanced carbohydrates, energy, amino acid metabolism cope stress, regeneration shoot. study reveals regenerative strategy perennial forage grasses, helping optimize resource utilization, increase yield, grassland stability resilience.

Soil salinization poses a significant ecological and environmental challenge both in China across the globe. Plant growth-promoting rhizobacteria (PGPR) enhance plants' resilience against biotic abiotic stresses, thereby playing vital role soil improvement vegetation restoration efforts. PGPR assist plants thriving under salt stress by modifying plant physiology, enhancing nutrient absorption, synthesizing hormones. However, mechanisms through which regulate contents of carbon (C) nitrogen (N), biomass allocation desert response to is still unclear. This study explores impact on allocation, C, N R. soongorica seedlings pot experiment. Strains P6, N20, N21, identified as Enterobacter, were isolated from rhizosphere soongorica, they exhibited various beneficial traits such indole-3-acetic acid (IAA) production, phosphate solubilization, fixation, tolerance up 8% NaCl stress. We found that stress, exhibit reductions height, basal diameter, root surface area (P<0.05). inoculation with strains N21 reverses these trends. Compared treatment alone, co-treatment significantly increases roots, stems, leaves, particularly biomass, 99.88%, 85.55%, 141.76%, respectively Moreover, decrease stems C increase roots leaves compared Specifically, 14.50%, 12.47%, 8.60%, while 4.96%, 4.45%, 4.94%, Additionally, stem leaf biomasses positive correlation negative tissues. In conclusion, Enterobacter enhanced seedlings, regulated distribution, modifies promote growth improve tolerance. provides novel adaptive strategy for integrated use halophytes saline-alkali
