This review analyzes PGPR's role in enhancing soil nutrients and plant growth, suggesting strategies for effective application in agriculture.
Plant Growth-Promoting Rhizobacteria (PGPR) are key bio-agents for sustainable agriculture. This review conceptualizes PGPR as rhizosphere engineers that enhance soil nutrients, restructure microbial networks, and boost plant stress tolerance. While their mechanisms are well-understood in the lab, a significant translational gap limits field efficacy due to inconsistent colonization and environmental context-dependency. We critically analyze this gap and propose integrated strategies—from advanced formulations to synthetic consortia—to unlock the reliable application of PGPR for global food security.
