Microbial synthetic community ARC prevents aflatoxin and increases rhizobia‐legume nodulation couplingly

Develop a novel strategy for exploring a dual-functional microbial synthetic community. Invent the SynCom ARC, which achieves aflatoxin control and rhizobia nodulation induction coupling in peanut. SynCom ARC inhibits A. flavus growth and reduces peanut aflatoxin levels by 85.6% in 4 year field trials. SynCom ARC enhances peanut nodulation and nitrogenase activity, retains active nodules at harvest, and boosts yield without super nodulation penalty in 325 sites of 19 provinces. SynCom ARC inhibits multiple targets in A. flavus, recruits and activates nodulation and nitrogen fixation in rhizobia and peanut, and improves photosynthesis and carbon supply for aflatoxin prevention and nodulation induction, balancing yield increase.
