Abstract Introduction: This study is the first to investigate the genetic diversity of plant growth-promoting genes in rhizobacteria isolated from the wild ecology of Mount Erciyes, Türkiye. It has a flora rich in flowering plants, with 1170 plant taxa, 194 of which are endemic to the area. Methods: A total of 165 bacterial isolates, including Azotobacter sp., Azospirillum sp., and Bacillus sp., were screened for genes associated with plant growth promotion: nitrogen fixation (nif), indole pyruvate decarboxylase (ipdC), 1-aminocyclopropane-1-carboxylate deaminase (accd), phosphate-solubilizing genes (Acpho, Alpho and phy), and siderophore biosynthesis (sd). Results: The analysis revealed significant genetic variability across isolates, particularly for nif and sd genes, with distinct band patterns indicating genetic diversity among Azospirillum and Bacillus isolates. Discussion: The findings emphasize the role of these rhizobacteria in nutrient cycling and stress resilience, potentially enhancing plant growth in nutrient-limited soils. In the current study, it contributes to understanding microbial biodiversity in Mount Erciyes and suggests a promising potential for sustainable agriculture through plant-microbe interactions.
