The xenognostic mechanisms of two multi-host pathogens, the causative agent of crown gall tumors Agrobacterium tumefaciens and the parasitic plant Striga asiatica, are compared. Both organisms are general plant pathogens and require similar information prior to host commitment. Two mechanistic strategies, chemical perception and metabolic complementation, are used to ensure successful host commitment. The critical reactions at host-parasite contact are proton and electron transfer events. Such strategies may be common among multi-host pathogens.

多宿主/病原体相互作用的化学生物学：化学知觉和代谢互补。

比较了两种多宿主病原体的冠状动脉瘤农杆菌和寄生植物Striga asiatica的致病机理。两种生物都是一般的植物病原体，在寄主承诺之前需要类似的信息。两种机制策略，化学感知和代谢互补，可用于确保成功的宿主承诺。宿主与寄生虫接触的关键反应是质子和电子转移事件。这种策略在多宿主病原体中可能很常见。
