Soil microbes play an important role in plant invasion, and parasitic plants regulate the growth of invasive plants. However, the mechanisms by which parasitic plants regulate the effects of soil microbes on invasive plants have not been investigated. Here, we used the invasive plant and the holoparasitic plant to test whether and how parasitism shifts the effect of native soil microbes on the growth of . In a factorial setup, was grown in pots with the presence versus absence of parasitism and the presence versus absence of native soil microbes. The findings showed that native soil microbes increased the biomass and clonal growth of only in the absence of a parasite, whereas parasitism decreased the biomass and clonal growth of only in the presence of soil microbes. In addition, the presence of soil microbes increased the deleterious effects of the parasite on . These results indicate that parasitism can shift the effects of native soil microbes on the growth of the invasive plant . Our results enrich the understanding of the mechanisms underlying the success of plant invasion.
土壤微生物在植物入侵中发挥着重要作用，而寄生植物会调节入侵植物的生长。然而，寄生植物调节土壤微生物对入侵植物影响的机制尚未得到研究。在此，我们使用入侵植物和全寄生植物来测试寄生是否以及如何改变本地土壤微生物对[植物名称]生长的影响。在析因实验设置中，[植物名称]种植于有或无寄生以及有或无本地土壤微生物的花盆中。研究结果表明，仅在没有寄生虫的情况下，本地土壤微生物才会增加[植物名称]的生物量和克隆生长，而仅在有土壤微生物的情况下，寄生才会降低[植物名称]的生物量和克隆生长。此外，土壤微生物的存在增加了寄生虫对[植物名称]的有害影响。这些结果表明，寄生可以改变本地土壤微生物对入侵植物[植物名称]生长的影响。我们的结果丰富了对植物入侵成功背后机制的理解。
