Factors Regulating Symbiotic Nitrogen Fixation Efficiency in Legume Crops: Mechanisms, Environmental Constraints, and Future Perspectives
Symbiotic nitrogen fixation (SNF) is a fundamental biological process that enhances legume productivity while reducing dependence on synthetic nitrogen fertilizers. However, its efficiency varies considerably across production systems because it is regulated by complex interactions among plant genetics, rhizobial compatibility, physiological processes, environmental conditions, and agronomic management. This review synthesizes current knowledge on the mechanisms […]
