Understanding the plant microbiome is a key for plant health and controlling pathogens. Recent studies have shown that plants are responsive towards natural and synthetic sound vibration (SV) by perception and signal transduction, which resulted in resistance towards plant pathogens. However, whether or not native plant microbiomes respond to SV and the underlying mechanism thereof remains unknown. Within the present study we compared grapevine-associated microbiota that was perpetually exposed to classical music with a non-exposed control group from the same vineyard in Stellenbosch, South Africa. By analyzing the 16S rRNA gene and ITS fragment amplicon libraries we found differences between the core microbiome of SV-exposed leaves and the control group. For several of these different genera, e.g., and , a host-beneficial or pathogen-antagonistic effect has been well studied. Moreover, abundances of taxa identified as potential producers of volatile organic compounds that contribute to sensory characteristics of wines, e.g., , , and , were either increased or even unique within the core music-exposed phyllosphere population. Results show an as yet unexplored avenue for improved plant health and the terroir of wine, which are important for environmentally friendly horticulture and consumer appreciation. Although our findings explain one detail of the long-term positive experience to improve grapevine's resilience by this unusual but innovative technique, more mechanistic studies are necessary to understand the whole interplay.
了解植物微生物群是实现植物健康和控制病原体的关键。最近的研究表明，植物通过感知和信号转导对自然和合成声振动（SV）产生反应，从而对植物病原体产生抗性。然而，本地植物微生物群是否对声振动做出反应及其潜在机制仍然未知。在本研究中，我们将长期暴露于古典音乐的葡萄相关微生物群与来自南非斯泰伦博斯同一葡萄园的未暴露对照组进行了比较。通过分析16S rRNA基因和ITS片段扩增子文库，我们发现暴露于声振动的叶片核心微生物群与对照组之间存在差异。对于其中几个不同的属，例如[此处原文缺失具体属名]，其对宿主有益或对病原体有拮抗作用已得到充分研究。此外，被鉴定为有助于葡萄酒感官特征的挥发性有机化合物潜在生产者的分类群，例如[此处原文缺失具体属名]，在暴露于音乐的核心叶际菌群中丰度要么增加，甚至是独一无二的。结果表明，这是一条尚未探索的改善植物健康和葡萄酒风土的途径，这对环境友好型园艺和消费者喜好都很重要。虽然我们的研究结果解释了通过这种不寻常但创新的技术提高葡萄复原力的长期积极经验的一个细节，但仍需要更多的机制研究来理解整个相互作用。
