Metabolomic and phytohormonal responses of Pseudomonas fluorescens and Bacillus subtilis to PEG-induced osmotic stress
Plant growth-promoting rhizobacteria are widely associated with plant drought tolerance, but their intrinsic metabolic responses to reduced-water-availability conditions remain incompletely characterized. This study compared the phytohormonal and culture-associated metabolite profiles of Pseudomonas fluorescens P...
