Metabolic Characteristics of PGPR-Induced Growth Promotion in Alfalfa (<i>Medicago sativa</i> L.).

ABSTRACT: Background/Objectives: Plant growth-promoting rhizobacteria (PGPR) have demonstrated potential for enhancing plant growth; existing research inadequately characterizes the metabolic underpinnings of PGPR-induced plant phenotypes. Methods: A deeper investigation into the impact of PGPR on plant metabolic pathways is crucial for a comprehensive understanding of their growth-promoting mechanisms and for the development of more effective biofertilizers and plant protection strategies. Results: To clarify the core metabolic pathways targeted by PGPR strains, we selected alfalfa as the research object, employed two Pseudomonas combinations, and utilized a broad-targeted metabolomics approach to investigate the metabolic characteristics of alfalfa roots.
