Global warming increasingly challenges agricultural productivity due to rising salt and water scarcity stress. In response these challenges, the present study investigates potential of dark septate endophytes (DSEs) from Khawrihnim Village, Mizoram, India, enhance tolerance upland rice (Oryza sativa). Two DSE species, Acrocalymma vagum Alternaria chlamydospora, were identified examined for their enhancement plant resilience The result showed that both species substantially impacted seed germination, biomass accumulation, oxidative stress responses under conditions. Biomass content was augmented elevated levels (-0.90 MPa), suggesting possible mechanisms. Increased superoxide dismutase activity diminished malondialdehyde conditions underscored DSE's capacity alleviate reactive oxygen lipid peroxidation in plants. Furthermore, shoot germination rates markedly enhanced by 60% using DSEs as biofertilizers, particularly evident direct treatments. These findings highlight efficacy chlamydospore biofertilizers development adverse environmental Their augment abiotic promote sustainability presents a significant opportunity enhancing crop output, especially areas susceptible

Drought constitutes a major abiotic stress factor adversely affecting plant growth and productivity. Plant-microbe symbiotic associations have evolved regulatory mechanisms to adapt environmental conditions. However, the interactive effects of different fungi on host tolerance under drought conditions remain unclear.

As climate change and water scarcity increasingly threaten agricultural productivity, enhancing plant resilience to drought has attracted great attention. This study explored the potential of combining Fe2O3 nanoparticles (FeNPs), endophytic bacteria (EB), fungi (EF) boost tolerance in Thymus vulgaris. The research aimed assess how these combined treatments affect plant's physiological responses chemical composition under stress. A factorial experiment was designed using completely randomized design (CRD) method, incorporating four irrigation levels [100%, 75%, 50%, 25% field capacity (FC)], FeNPs concentrations (0, 0.5, 1, 1.5 mg L−1), three endophyte types (control, bacteria, fungi). After extracting, purifying, identifying, screening EB EF from nine Lamiaceae species, endophytes Azospirillum lipoferum Aspergillus oryzae isolated Salvia mirzayanii exhibited highest resistance. amounts TFM (45.45 g) TDM (21.56 were obtained combination at 1 L−1 with 100% FC.
