SUMMARY:

Bacteria belonging to the Klebsiella genus are widely known in the medical field, but their potential in agriculture is still poorly explored. In this regard, in the present study, a systematic review and meta-analysis was performed to investigate the effects of endophytic Klebsiella bacteria in promoting plant growth. 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 with functional versatility in phytohormone production, nutrient solubilization and pathogen control in agricultural systems in tropical and temperate zones. The results also showed a significant correlation between the use of Klebsiella bacteria and plant growth, highlighting the positive impact on the control of aggressive pathogens. In addition, the present study characterized the bacterium K. pneumoniae (isolate 29Y), previously isolated from cassava roots (Manihot esculenta), through genomic sequencing. Preliminary results showed a genome larger than 5 megabases and the presence of genes potentially related to plant growth promotion, including nitrogen fixation. It was also possible to perform a more precise identification of this bacterial isolate, initially classified as K. pneumoniae, but which with the genomic sequencing data will probably be redefined as K. variicola, a species with greater potential in the agricultural area.
