摘要

Klebsiella is a bacterial genus widely recognized in the medical field but with underexplored potential in agriculture. This study employed a systematic review and meta-analysis to investigate scientific articles on plant growth promotion effects associated with endophytic bacteria Klebsiella species. A total of 39 relevant studies, published between 2012 and 2024, were identified based on strict inclusion and exclusion criteria. The analysis revealed that Klebsiella sp., K. pneumoniae, and K. variicola are cosmopolitan species that have functional versatility in phytohormone production, nutrient solubilization, and pathogen control in agricultural systems in both tropical and temperate zones. The data showed a significant correlation between the use of Klebsiella sp. and plant growth, highlighting the positive impact of these species in controlling aggressive pathogens. These findings underscore the potential of Klebsiella as a biotechnological tool for sustainable agricultural practices, enhancing plant growth and reducing the reliance on chemical inputs. The study further emphasizes the need for future research to deepen genomic characterization and expand the agricultural applications of these bacteria.
