Aims

Soil microbiome roles in agriculture is becoming more and more important. This importance is also reflected on the way plants are seen: complex organisms formed by the plant itself plus the microbes inhabiting its tissues, including the ones on the surface of every organ and the ones adhered or in proximity to the roots. In addition, as already demonstrated, the microbial community associated with a specific soil is able to predetermine the health status of crops. For all the above mentioned reasons, defining the microbial composition of agricultural soils and the factors driving the assemblage is pivotal to achieve more sustainable agriculture and viticulture.

Methods

We aimed to investigate how the soil geological characteristics influence the microbiome composition associated with close geographically related vineyards. Moreover, we studied both the top (15 cm in depth) and deep (120 cm in depth) soil layers as anthropically influenced and almost-undisturbed soil, respectively.

Results

We observed slightly different microbial communities despite the close geographical proximity of the two vineyards, which is considered one of the main determinants of the soil microbiome composition. In addition, we found that the geological characteristics of the two soils influence both the root distribution and the accumulation of pathogen- and symbiont-related genera. Sensory profiles of the Grillo wines from the two different soils confirmed the tight link between soil origin and wine traits.

Conclusions

In the present study, we highlight that the geological characteristics of soil can influence soil microbial composition and assemblage in close geographically related vineyards, with a potential effect on wine features.

对土壤特性和微生物群落的微观分析揭示了对植物和水果的潜在影响：以葡萄园为例

目的

土壤微生物组在农业中的作用越来越重要。这种重要性还体现在观察植物的方式上：植物本身加上栖息在其组织中的微生物形成的复杂生物，包括每个器官表面的微生物以及附着或靠近根部的微生物。此外，正如已经证明的那样，与特定土壤相关的微生物群落能够预先确定农作物的健康状况。由于上述所有原因，确定农业土壤的微生物组成和驱动其聚集的因素对于实现更可持续的农业和葡萄栽培至关重要。

方法

我们旨在研究土壤地质特征如何影响与紧密相关的葡萄园相关的微生物组组成。此外，我们分别研究了受人为影响和几乎未受侵蚀的土壤的顶层（深度15厘米）和深层（深度120厘米）。

结果

尽管两个葡萄园的地理位置接近，但我们观察到的微生物群落略有不同，这被认为是土壤微生物组组成的主要决定因素之一。此外，我们发现两种土壤的地质特征既影响根系分布，也影响病原体和共生体相关属的积累。来自两种不同土壤的Grillo葡萄酒的感官特征证实了土壤起源与葡萄酒特性之间的紧密联系。

结论

在本研究中，我们强调土壤的地质特征会影响与地理相关的紧密葡萄园中土壤微生物的组成和组合，并对葡萄酒的特性产生潜在影响。
