Well known plant production systems should be re-evaluated due to findings that the interesting metabolite might actually be produced by microbes intimately associated with the plant, so-called endophytes. Endophytes can be bacteria or fungi and they are characterized usually by the feature that they do not cause any harm to the host. Indeed, in some cases, such as mycorrhizal fungi or other growth promoting endophytes, they can be beneficial for the plant. Here some examples are reviewed where the host plant and/or endophyte metabolism can be induced by the other partner. Also, partial or complete biosynthesis pathways for plant secondary metabolites can be attributed to such endophytes. In other cases the host plant is able to metabolize substances from fungal origin. The question of the natural role of such metabolic changes for the endophyte will be briefly touched. Finally, the consequences for the use of plant cultures for secondary metabolite production is discussed.
由于研究发现，有趣的代谢产物实际上可能由与植物密切相关的微生物（即所谓的内生菌）产生，因此应重新评估著名的植物生产系统。内生菌可以是细菌或真菌，其特征通常是它们不会对宿主造成任何伤害。事实上，在某些情况下，如菌根真菌或其他促进生长的内生菌，它们对植物有益。本文综述了一些宿主植物和/或内生菌代谢可被另一伙伴诱导的例子。此外，植物次生代谢产物的部分或完整生物合成途径可归因于此类内生菌。在其他情况下，宿主植物能够代谢来自真菌的物质。本文将简要探讨这种代谢变化对内生菌的自然作用问题。最后，讨论了利用植物培养生产次生代谢产物所带来的后果。
