Rhizobia promote the growth of plants either directly through N2 fixation, supply of nutrients, synthesis of phytohormones and solubilization of minerals, or indirectly as a biocontrol agent by inhibiting the growth of pathogens. The biocontrol effect of rhizobia is due to the secretion of secondary metabolites such as antibiotics and HCN. Siderophore production in iron stress conditions provides rhizobia an added advantage, resulting in exclusion of pathogens due to iron starvation.
根瘤菌通过固氮、养分供应、植物激素合成和矿物质溶解直接促进植物生长，或者作为生物防治剂通过抑制病原体生长间接促进植物生长。根瘤菌的生物防治作用归因于抗生素和HCN等次生代谢产物的分泌。在铁胁迫条件下产生铁载体为根瘤菌提供了额外优势，导致病原体因缺铁而被排除。
