Rhizobia: A Promising Source of Plant Growth-Promoting Molecules and Their Non-Legume Interactions: Examining Applications and Mechanisms

For over a century, the scientific community has had comprehensive understanding of how rhizobia can promote growth legumes by forming nitrogen fixing nodules. Despite this knowledge, interaction with non-legumes remained largely ignored as subject study until more recent decades. In last few years, research shown that also associate non-legume roots, which ultimately leads to stimulation through diverse direct and indirect mechanisms. example, enhance phytohormones production, improvement plant nutrient uptake, such solubilization precipitated phosphorus, production siderophores address iron needs, reduction ethylene levels ACC deaminase enzyme cope drought stress. Additionally, improve, indirectly, biocontrol pathogens induction systemic resistance in host plant. It increase root adherence soil releasing exopolysaccharides, regulate water movement. The objective review is assess analyze existing knowledge information regarding mechanisms non-legumes. By conducting analysis these findings, we aim gain new insights into development Rhizobium/non-legume interactions.
