微生物组在植物健康和性能中发挥着至关重要的作用，植物有益微生物组的发展可以通过有机肥料的投入来引导。特别是对肥料引起的细菌和真菌变化以及这些群体的变化如何改变植物性能进行了深入研究。然而，对原生生物群落的影响，包括它们在微生物组内的营养相互作用以及对植物性能的影响仍然很大程度上未知。在这里，我们跟踪了不同施肥方案（传统施肥、有机施肥和木霉生物有机施肥）下黄瓜六个生长季的整个微生物组，包括细菌、真菌和原生生物，并将微生物数据与植物产量联系起来，以确定促进植物生长的微生物。 （生物）有机施肥处理的产量较高。施肥制度改变了土壤非生物条件，其中（生物）有机施肥处理的显着影响。这些治疗还导致原生生物群落发生显着变化，尤其是食微生物的尾虫原生生物。我们发现这些原生生物与植物产量和潜在对植物有益的微生物的密度呈正相关。我们通过温室实验进一步探索了这些关系的机制后果，表明尾虫原生生物可以通过与植物有益微生物（包括生物肥料提供的生物制剂木霉菌）的相互作用，对植物生长产生积极影响。我们表明，原生生物可能通过微生物组相互作用在刺激植物性能方面发挥核心作用。未来的农业实践可能旨在专门增强对植物有益的原生生物，或将这些原生生物用作新型、可持续的生物肥料。视频摘要 在线版本包含可在 10.1186/s40168-021-01025-w 获取的补充材料。
Microbiomes play vital roles in plant health and performance, and the development of plant beneficial microbiomes can be steered by organic fertilizer inputs. Especially well-studied are fertilizer-induced changes on bacteria and fungi and how changes in these groups alter plant performance. However, impacts on protist communities, including their trophic interactions within the microbiome and consequences on plant performance remain largely unknown. Here, we tracked the entire microbiome, including bacteria, fungi, and protists, over six growing seasons of cucumber under different fertilization regimes (conventional, organic, and Trichoderma bio-organic fertilization) and linked microbial data to plant yield to identify plant growth-promoting microbes. Yields were higher in the (bio-)organic fertilization treatments. Soil abiotic conditions were altered by the fertilization regime, with the prominent effects coming from the (bio-)organic fertilization treatments. Those treatments also led to the pronounced shifts in protistan communities, especially microbivorous cercozoan protists. We found positive correlations of these protists with plant yield and the density of potentially plant-beneficial microorganisms. We further explored the mechanistic ramifications of these relationships via greenhouse experiments, showing that cercozoan protists can positively impact plant growth, potentially via interactions with plant-beneficial microorganisms including Trichoderma, the biological agent delivered by the bio-fertilizer. We show that protists may play central roles in stimulating plant performance through microbiome interactions. Future agricultural practices might aim to specifically enhance plant beneficial protists or apply those protists as novel, sustainable biofertilizers.
