摘要

This study investigates the isolation and characterization of multi-trait growth-promoting fungal endophytes from Phoenix dactylifera (date palm) roots and evaluates their potential as biofertilizers. Six distinct fungi were isolated, and their metabolic profiles were analyzed. Among these, DT-2, identified as Fusarium proliferatum, exhibited superior production of secondary metabolites, including 45.86 µg/mL indole acetic acid (IAA), 260.3 µg/mL flavonoids, 179.6 µg/mL phenolics, and 15.4 µg/mL proline. Inoculation of wheat seeds with DT-2 enhanced seed germination, root and shoot growth, and increased fresh weights (root: 1.73 g; shoot: 5.90 g). Additionally, DT-2 demonstrated the highest levels of secondary metabolites and photosynthetic pigments among the isolates. DT-2 was also found to enhance wheat's drought stress tolerance significantly. Under PEG-induced stress, DT-2-inoculated plants showed increased levels of beneficial hormones and antioxidants, demonstrating DT-2’s capacity to boost wheat resilience against drought by modulating key metabolic pathways. These findings highlight the potential of multi-trait plant growth-promoting Fusarium proliferatum as an effective biofertilizer, promoting plant growth and improving crop performance under drought stress conditions.
