Variation in microbial community composition across vineyard plots. Dissimilarities among A fungal and B bacterial communities in the topsoil, phyllosphere and leaf endosphere for the five pairs of plots sampled in 2022, represented using a Principal Component Analysis (PCA). Samples collected from the same pair of plots are shown in the same color, with symbols indicating high and low downy mildew incidence and severity (triangles and circles, respectively)
