| Summary: | In this study, bacteria associated with licorice (<i>Glycyrrhiza glabra</i> L.) were characterized through 16S rRNA gene analysis. Profiling of endophytic bacteria isolated from <i>Glycyrrhiza glabra</i> tissues revealed 18 isolates across the following genera: <i>Enterobacter</i> (4), <i>Pantoea</i> (3), <i>Bacillus</i> (2), <i>Paenibacillus</i> (2), <i>Achromobacter</i> (2), <i>Pseudomonas</i> (1), <i>Escherichia</i> (1), <i>Klebsiella</i> (1), <i>Citrobacter</i> (1), and <i>Kosakonia</i> (1). Furthermore, the beneficial features of bacterial isolates for plants were determined. The bacterial isolates showed the capacity to produce siderophores, hydrogen cyanide (HCN), indole-3-acetic acid (IAA), chitinase, protease, glucanase, lipase, and other enzymes. Seven bacterial isolates showed antagonistic activity against <i>F. culmorum</i>, <i>F. solani</i>, and <i>R. solani</i>. According to these results, licorice with antimicrobial properties may serve as a source for the selection of microorganisms that have antagonistic activity against plant fungal pathogens and may be considered potential candidates for the control of plant pathogens. The selected bacterial isolates, <i>P. polymyxa</i> GU1, <i>A. xylosoxidans</i> GU6, <i>P. azotoformans</i> GU7, and <i>P. agglomerans</i> GU18, increased root and shoot growth of licorice and were able to colonize the plant root. They can also serve as an active part of bioinoculants, improving plant growth. |
