a Principal Component Analysis (PCA) of 23 V. vinifera whole-genome resequenced genotypes by [9]. The samples selected in this study to perform the repeatome comparative analysis are red-dotted, namely Adjaruli Tetri (ADJ), Aglianico (AGL), Airen (ARN), Chardonnay (CHR), Chasselas Blanc (CHS), Enantio (ENT), Falanghina (FAL), Gamay Noir (GMY), Greco Bianco (GRC), Lambrusco di Sorbara (LBS), Mgaloblishvili (MGL), Mtsvane Kachuri (MTS), Muscat of Alexandria (MSL), Muscat Petits Grains Blanc (MSP), Nebbiolo (NBL), Nosiola (NSL), Ojaleshi (OJL), Pinot Noir (PNT), Schiava Gentile (SCH), Semillon (SML), Sultanina (SLT), Terbash (TRB), Tschvediansis Tetra (TSC). b Proportion of DNA repetitive sequences identified. (C) PCA of different grape cultivars based on their repeats landscape. Clustering was performed with K-means and colors were assigned according to the cluster. c Boxplots showing the most significant and enriched families of repeats in clusters 1 and 2 of PCA shown in (c). Wilcoxon test results are shown for each repeat class
