| Research Abstract |
Gram-negative, root-colonizing biocontrol bacterium Pseudomonas fluorescens produces antibiotics as its secondary metabolites through the Gac/Rsm signal transduction pathway, and it contributes to plant protection from pathogens. In this study, metabolomic profiling was perfotmed on Gac/Rsm mutants. Among the metabolites regulated by the Gac/Rsm system, intracellular alarmone ppGpp was characterized in detail.
