It has recently been discovered that when symbiotic Rhizobium and Bradyrhizobium cells are outside the plant they are also exposed to the isoflavonoid phytoalexins that are normally associated with pathogenic infections. How the symbionts elicit and respond to isoflavonoids may help to define the mechanisms that are used by other beneficial soil microorganisms to colonize plant roots.
最近发现，当共生的根瘤菌和慢生根瘤菌细胞处于植物体外时，它们也会接触到通常与病原体感染相关的异黄酮植保素。共生体如何引发并响应异黄酮，可能有助于确定其他有益土壤微生物在植物根部定殖所采用的机制。
