| Outline of Final Research Achievements |
The Gram-negative species of Pseudomonas protegens are known as plant-protecting bacteria, as they suppress the growth of pathogenic microbes in rhizosphere by producing antimicrobial secondary metabolites via the Gac/Rsm signal transduction pathway. In this study, we identified the novel gene clusters which are involved in potential biocontrol activities. Furthermore, from the metabolome data obtained previous study, we suggest an important role of GABA in the Gac/Rsm-regulated niche adaptation of P. protegens CHA0 to plant roots.
